Decreased permeability into the resistant bacterial cells (chloramphenicol appears to enter bacterial cell both by passive diffusion as well as by facilitated transport) and lowered affinity of bacterial ribosome for chloramphenicol are the other mechanisms of resistance. Dose and clinical application in influenza A is similar to amantadine and it is being preferred over the latter. Emergency postcoital contraception should be reserved for unexpected or accidental exposure (rape, condom rupture) only, because all emergency regimens have higher failure rate and side effects than regular low-dose combined pill. Chlorthalidone is longer acting (~ 48 hours) than hydrochlorothiazide (< 24 hours) and may have better round-the-clock action. Any diuretic acting proximal to the aldosterone sensitive ion exchange site causes an increased delivery of Na+ to the distal nephron-more exchange with K+ takes place. However, the doses should be so spaced that the surviving organisms again start multiplying and a cidal action is exerted. Terazosin, Doxazosin these are long-acting congeners of prazosin with similar properties but suitable for once daily dosing (see p. Worsening of levodopa adverse effects such as nausea, vomiting, dyskinesia, postural hypotension, hallucinations, etc. They act by reducing the unbalanced cholinergic activity in the striatum of parkinsonian patients. Corticosteroids are generally used for short term, and discontinued after remission is induced. The H1 receptors are widely distributed in the brain, where high densities are found in regions linked to neuroendocrine, behavioral, and nutritional state control. Their function appears to be aimed at maintaining blood glucose levels during starvation-so that brain continues to get its nutrient. Phenytoin is available in two types of oral formulations that differ in their pharmacokinetics: rapid-release and extended-release forms. In the periphery, it consists of nerves, ganglia, and plexuses that innervate the heart, blood vessels, glands, other visceral organs, and smooth muscle in various tissues. The net result is neurite extension, cell growth, antiapoptosis, and cell survival. Caspofungin is approved for use in deep and invasive candidiasis, esophageal candidiasis and salvage therapy of nonresponsive invasive aspergillosis. It is 90% bound to plasma proteins, partly metabolized in liver to inactive products and excreted by kidney. Cautious use of low doses of an appropriate drug for the type of sleep disturbance may be made. The patient may have a personality disorder, but often there is no specific stress factor. Insulin glulisine: Another rapidly acting insulin analogue with lysine replacing asparagine at B 23 and glutamic acid replacing lysine at B 29. Dietary restrictions and drug interactions with monoamine oxidase inhibitors: the state of the art. Anaemia, phlebitis, tremor, convulsions and other neurological as well as constitutional symptoms due to hypocalcaemia are frequent. Magnesium ions release cholecystokinin which augments motility and secretion, contributing to purgative action of Mag. These conjugation reactions usually require the substrate to have oxygen (hydroxyl or epoxide groups), nitrogen, and sulfur atoms that serve as acceptor sites for a hydrophilic moiety, such as glutathione, glucuronic acid, sulfate, or an acetyl group, that is covalently conjugated to an acceptor site on the molecule. With early recognition and stoppage of the drug, visual toxicity is largely reversible. However, tolerance quickly develops to this action (probably due to receptor down-regulation) and undesirable alteration of bacterial flora limit use of erythromycin as a prokinetic agent. However, a high fraction is acetylated, which is relatively insoluble-crystalluria can occur. Cefotaxime It is the prototype of the third generation cephalosporins; exerts potent action on aerobic gram-negative as well as some grampositive bacteria, but is not active on anaerobes (particularly Bact. Atropine has a t1/2 of about 4 h; hepatic metabolism accounts for the elimination of about half of a dose, and the remainder is excreted unchanged in the urine.

They can reflexly stimulate gravid uterus, therefore are contraindicated during pregnancy. Following antibody binding, the T-cell receptor is internalized and the T-cells get rapidly depleted from blood, partly by cytolysis and partly by their migration to non-lymphoid organs. Nasal irritation, sneezing, crusting, itching of throat and dryness may occur, especially in the beginning. No goiter occurs if antithyroid drugs are given to hypophysectomised animals or if T4 is given along with them. Initially, when disease is mild, only anticholinergics or selegiline may be sufficient. The combination has the potential to cause serious adverse effects (exfoliative dermatitis, StevensJohnson syndrome, etc. Their fixed dose combinations with antitussives are not satisfactory because of differences in time course of action of the components and liability for indiscriminate use. Long-term treatment decreases the cellular inflammatory response; bronchial hyperreactivity is reduced to variable extents. Penfluridol An exceptionally long acting neuroleptic, recommended for chronic schizophrenia, affective withdrawal and social maladjustment. Late: Behavioral alterations, mental confusion, hallucinations, psychosis-are more prominent than with levodopa. Characterization of ethosuximide reduction of lowthreshold calcium current in thalamic neurons. In contrast, a convincing role for 2A adrenergic receptor polymorphisms in human type 2 diabetes has been elucidated. Drug concentrations are subsequently measured, and dosage is adjusted if necessary (described further in the chapter). Chronic use of large doses cause negative N2 balance by increased conversion of protein to carbohydrate. Alongwith vit A to enhance its absorption and storage, and in hypervitaminosis A to reduce its toxicity. Toxicology of Drugs With Antimuscarinic Properties the deliberate or accidental ingestion of natural belladonna alkaloids is a major cause of poisonings. Muscle dystonia and other extrapyramidal side effects are the most important limiting features. This is the most important measure; prevents retinal damage and other symptoms; large quantities may be needed. There are several reasons which could account for failure of this patient of iron deficiency anaemia to respond to the oral iron medication she has been taking: Taking 160 mg of ferric ammonium citrate (iron content 20%) would provide just 32 mg of elemental iron/day. Ultralente (long-acting) and semilente (short-acting) are not separately marketed. There is no cephalopelvic disproportion or any other contraindication to normal vaginal delivery. The latter combination avoids use of a calcineurin inhibitor, and is particularly suitable for patients developing renal toxicity with cyclosporine. Nalidixic acid is absorbed orally, highly plasma protein bound and partly metabolized in liver: one of the metabolites is active. Patients in severe pain require higher doses of opioids and tolerate them without manifesting toxicity. Glutamate is the principal agonist at both ionotropic and metabotropic receptors for glutamate and aspartate. Thus, it is one of the most popular alkylating agents useful in many solid tumours. It is nearly equipotent antitussive as codeine, especially useful in spasmodic cough. As a matter of practicality, the number of animals used in experiments on toxic materials usually will be small compared with the size of human populations potentially at risk.

This may play a role in the analgesic action of morphine in conditions like burns and trauma. Fluconazole is 94% absorbed; oral bioavailability is not affected by food or gastric pH. Thus, uptake blockade appears to initiate a series of time-dependent changes that culminate in antidepressant effect. A variety of vascular, neurogenic, hormonal, pharmacologic or psychogenic causes may underlie the disorder. The first to be introduced was chlortetracycline in 1948 under the name aureomycin (because of the golden yellow colour of S. When toxicity is due to acute ingestion of large doses of digoxin, plasma K+ may be high; it should not be given from outside. One should not hesitate to use adequate dose of a bulk forming agent, lactulose or docusates. It binds the Rho antigens and does not allow them to induce antibody formation in Rh negative individuals. Interactions (a) Allopurinol inhibits the degradation of 6-mercaptopurine and azathioprine: their doses should be reduced to 1/3rd, but not that of thioguanine, because it follows a different metabolic path (S-methylation). Atracurium, vecuronium, doxacurium, pipecuronium, mivacurium, and rocuronium are even more selective, showing less ganglionic blockade (Naguib et al. Atropine is added in subpharmacological dose to discourage abuse by taking several tablets. Over the past 40 years they have been among the most intensely investigated substances. Haemostatic plug of platelets formed at the site of injury to blood vessels is reinforced by fibrin deposition to form a thrombus. This fact probably explains their differing sensitivity to the various -lactam antibiotics. It occurs due to stimulation of mechano- or chemoreceptors in throat, respiratory passages or stretch receptors in the lungs. Status Epilepticus and Other Convulsive Emergencies Status epilepticus is a neurological emergency. After a week, he was brought with incoherent talking, drowsiness, tremor and ataxia. Being a basic drug it is partitioned to the acid gastric juice, ionizes there and does not diffuse back into blood. In the past decade many large scale placebo controlled randomized interventional trials and cohort studies have yielded opposite results. Uses Mephenamic acid is indicated primarily as analgesic in muscle, joint and soft tissue pain where strong antiinflammatory action is not needed. A practical distinction between the two on the basis of a growth inhibiting versus direct lethal action is futile because these are often concentration dependent actions. At high concentrations, cisapride blocks delayed rectifying K+ channels in heart-prolongs Q-Tc interval and predisposes to torsades de pointes/ventricular fibrillation. Because of slow and persistent nature of action, sedative and subjective effects are less 7. Pituitary Gland Dopamine is the primary regulator of prolactin secretion from the pituitary gland. Several checkpoints typically exist to identify and prevent an adverse drug event, and that adverse event can only occur if holes in several systems align. These transporters ensure that vesicles fill rapidly during neurotransmission and provide a means for reducing cytoplasmic concentrations of neurotransmitter in areas where rates of reuptake are high. Ciclopirox olamine It is a newer drug effective in tinea infections, pityriasis versicolor and dermal candidiasis. About 90% of the cases occur in India, Bangladesh, Nepal, Sudan and Brazil, but the disease is also present in other countries of East Africa, South America, Mediterranean basin and central Asia. C, left panel) and the Eadie-Hofstee transformation of the transport data (v/C vs.

Intravaginal misoprostol is now favoured by many as it produces fewer side effects. Side effects that occur in their use to relieve anxiety are-sedation, light-headedness, psychomotor and cognitive impairment, confusional state (especially in the elderly), increased appetite and weight gain, alterations in sexual function. Ether is not used now in developed countries because of its unpleasant and inflammable properties. Responses are monitored from compound action potentials or muscle tension developed in the adductor pollicis (thumb) muscle. However, because of the availability at more convenient and better tolerated albendazole/mebendazole it is now considered a second choice drug. It may be useful in some cases of rheumatoid and osteoarthritis but has no distinct advantage. This is especially valuable for obstetric purposes (mother can participate in labour without feeling pain) and for postoperative pain relief. Low dose maintenance or intermittent regimens of antipsychotics have been tried in relapsing cases. Muscular weakness: proximal (shoulder, arm, pelvis, thigh) muscles are primarily affected. Reactions carried out by phase 1 enzymes usually lead to the inactivation of a drug. The most appropriate drugs and regimens for treating chlamydial endocervicitis are: Azithromycin 1. The wall of the pore is formed by all four S5-S6 segments, while the short nonhelical loops connecting S5S6 on the extracellular surface fold into the pore and serve as the activation gate. The choice depends on the particulars of the patient, the infecting organism and the drug. Uterine contractions are provoked and the conceptus is expelled within the next few hours. In many cases, this plasmid has also carried resistance to ampicillin and tetracycline. Evidence for Neurohumoral Transmission the concept of neurohumoral transmission or chemical neurotransmission was developed primarily to explain observations relating to the transmission of impulses from postganglionic autonomic fibers to effector cells. Absorption of its complex salt with ampicillin- sultamicillin tosylate is better, which is given orally. Acute rheumatic fever Aspirin is the first drug to be used in all cases; other drugs are added or substituted only when it fails or in severe cases (corticosteroids act faster). Carvedilol has been tested in numerous controlled trials (Cleland, 2003; Poole-Wilson et al. Brief spurts in linear growth can be induced by anabolic steroids, but this probably does not make a difference in the final stature, except in hypogonadism. Routine and long-term use must be discouraged, because it can produce colonic atony. An alternative approach has been to use "atypical" antipsychotic agents (see Chapter 16). These conditions are benefited by baclofen, diazepam, tizanidine and dantrolene but not by mephenesin group of drugs. The response of the human uterus varies, but there usually is an increase in tone. Other allergic manifestations are rare with erythromycin base or esters other than estolate. Conduction refers to the passage of an electrical impulse along an axon or muscle fiber. In addition, dose dependent adverse effects noted when use is made for other indications are- 1.

However, due to the development of insecticide resistance among mosquitoes and other factors, it staged a comeback in the mid 1970s (6. While humans can now choose their dietary sources, a typical animal does not have this luxury and as a result is subject to its environment and the vegetation that exists in that environment. Oral diazepam administered 1 hr before is also used with the limitation that level of sedation cannot be titrated. Certain irritants also produce a remote effect which tends to relieve pain and inflammation in deeper organs-called Counter-irritants. Astringent action of alcohol is utilized in antiperspirant and aftershave lotions. Except for these unusual instances and rare genetic abnormalities of biotin dependent enzymes, there are no clearly defined therapeutic uses of biotin. Because they inhibit platelet function, use with anticoagulants should, nevertheless, be avoided. Efficacy of all chelating agents in promoting excretion of the toxic metal and in reversing toxic manifestations declines rapidly as the interval between entry of the metal in the body and the administration of the chelator increases. Antitussives (Cough centre suppressants) (a) Opioids: Codeine, Ethylmorphine, Pholcodeine. In practice situations, these in vitro interactions occur when injectable drugs are mixed in the same syringe or infusion bottle. Labetalol has been recommended as treatment of acute severe hypertension (hypertensive emergency). Methylcellulose It is a synthetic cellulose derivative used as bulk purgative, in nose drops and contact lens solutions. The cidal action of these drugs appears to be based on secondary changes in the integrity of bacterial cell membrane, because other antibiotics which inhibit protein synthesis (tetracyclines, chloramphenicol, erythromycin) are only static. Ankle edema is not due to fluid retention, but because of greater dilatation of precapillary than postcapillary vessels. Oral hypoglycaemics should be used to supplement dietary management and not to replace it. It has been promoted for: Sequelae of cerebrovascular accidents, head injury, prolonged anaesthesia. Combination of inhaled ipratropium with 2 agonist produces more marked and longer lasting bronchodilatation; since their effects are additive. It has caused respiratory depression, paralytic ileus and toxic megacolon in children. Nicotine is readily absorbed from the respiratory tract, buccal membranes, and skin. Higher cardiac mortality has been reported among patients with steady-state plasma digoxin levels > 1. Iron should be normally administered orally; parenteral therapy is to be reserved for special circumstances. His heart (ventricular) rate can be controlled by a drug which depresses A-V conduction. When a counter-irritant is applied to the area of skin supplied by nerves from the same segment as the deeper organ from which pain impulses are coming, the cutaneous impulses obscure the deeper sensation. Other proposed uses are-in endometriosis, uterine fibroid, certain breast cancers and in meningioma. Absorption and fate All three forms of the vitamin are well absorbed from the intestine. This led to the discovery and cloning of the two cannabinoid receptors and the identification of endogenous compounds that modulate them. Trying to treat untreatable (viral) infections or other causes of fever (malignancy, collagen diseases). Glyceryl trinitrate, the drug unsurpassed in its ability to abort and terminate anginal attack, was introduced by Murrell in 1879. Of the three major classes of antianginal drugs described above, generally one agent is used initially; choice depends on the stage and severity of disease, associated cardiac/other medical conditions and individual acceptability of side effects.

Divalproex, a compound of valproate, is more commonly used due to better gastric tolerance. Cefprozil this 2nd generation cephalosporin has good oral absorption (>90%) with augmented activity against Strep. These differences are important factors governing their choice for different uses. Though acyclovir eye ointment acts slower than idoxuridine eye drops, blindness can be prevented. However, all benzodiazepines possess sedative-hypnotic properties to varying degrees; these properties are exploited extensively clinically, especially to facilitate sleep. Dose: For roundworm infestation 4 g once a day for 2 consecutive days; children 0. Megaloblastic anaemia occurring in chronic alcoholism is due to interference with folate metabolism. Diarrhoea patients can be broadly placed in one of the two categories: (a) Abundant watery diarrhoea lacking mucus or blood, usually dehydrating with frequent vomiting, but little or no fever. Streptococcal pharyngitis, tonsillitis, mastoiditis and community acquired respiratory infections caused by pneumococci and H. It is administered by infusion with pre and post dose oral probenecid which inhibits its tubular secretion and improves its availability for entering into cells, as well as reduces nephrotoxicity. Bambuterol this biscarbamate ester prodrug of terbutaline is slowly hydrolysed in plasma and lungs by pseudocholinesterase to release the active drug over 24 hours. However, the site of action, ceiling effect, renal haemodynamic changes and duration of action are similar to furosemide. She went to a local doctor 2 months ago who got her blood tested, which showed Hb was 7. On being engulfed by the synovial cells, they release mediators and start an inflammatory response. Tenofovir was initially used only in previously treated patients, but because of good tolerability profile, it is now being included in first line regimens as well. Clozapine can be associated with significant orthostasis, even when titrated slowly. The only serious concern is 3-fold increase in risk of deep vein thrombosis and pulmonary embolism. Pharmacologically distinct phenotypes of 1Badrenoceptors: variation in binding and functional affinities for antagonists. The major action of estrogens is to reduce maturation and activity of osteoclasts by modifying regulatory cytokine signals from osteoblasts (see Ch. Drug interactions Oral absorption of itraconazole is reduced by antacids, H2 blockers and proton pump inhibitors. The disease often gets disseminated in immunocompromised individuals and may be treated with oral or i. This drug occasionally may be useful in treating selected patients with pheochromocytoma. It may be an alternative to long-term steroids in some other autoimmune diseases as well. However, promiscous and often indiscriminate use has gradually narrowed the field of their usefulness. It has prominent immunosuppressant property useful in rheumatoid arthritis, psoriasis and many other antoimmune disorders (see Ch.

This regimen has been found to prevent postoperative deep vein thrombosis without increasing surgical bleeding. In this patient, use of furosemide alone resulted in further hypokalaemia and alkalosis. Pantothenic acid Pantothenic acid is an organic acid, widely distributed in food sources, especially liver, mutton, egg yolk and vegetables. Notable bacilli that are not inhibited are Pseudomonas aeruginosa, Proteus, Klebsiella, Salmonella typhi and many Bact. However, it causes constriction of conjunctival vessels, clouding and rarely sloughing of cornea (due to drying and local tissue toxicity). Two derivatives of clonidine, apraclonidine and brimonidine, applied topically to the eye, decrease intraocular pressure with little or no effect on systemic blood pressure. Antianabolic effect of tetracycline increases urea production which is retained by the diuretic; Avoid concurrent use. However, it appears to be the most effective and most suitable of the antimotility antidiarrhoeal drugs. It also increases intestinal peristalsis to some extent, but has no significant action on colonic motility and gastric secretion. Genetic causes are solely responsible for rare forms inherited in an autosomal dominant or autosomal recessive manner. Larger molecules, such as proteins, slowly gain access to the circulation by way of lymphatic channels. Though cardiomyopathy can occur, major toxicity is marrow depression and mucosal inflammation. Bioavailability of iron from such preparations, though claimed to be good, is actually variable. Following uptake, catecholamines can be metabolized (in neuronal and nonneuronal cells) or re-stored in vesicles (in neurons). Similarly, the low degree penicillin-resistant gonococci are less permeable to penicillin G; chloroquine-resistant P. The major constraint in their long-term use for anxiety disorders is their potential to impair mental functions and to produce dependence. Lysosomal stabilization and free radical scavenging are the other proposed mechanisms. Being bacteriostatic, it is not suitable for treatment of enterococcal endocarditis. Adverse effects Laryngospasm occurs generally when respiratory secretions or other irritants are present, or when intubation is attempted while anaesthesia is light. The indications are-severe urinary, biliary, respiratory, skin-soft tissue infections, typhoid, meningitis and septicaemias. It is also good for patients with altered consciousness, because it does not cause sedation or increase intracranial pressure. It has also been used to improve harvesting of granulocytes because it accelerates erythrocyte sedimentation. Buspirone is used in the treatment of generalized anxiety disorder (Goodman, 2004). About 20% of halothane that enters blood is metabolized in the liver, the rest is exhaled out. The latent period between vaccination and development of immunity and the period for which it lasts depends primarily on the organism, but varies somewhat in different individuals. Barbiturates (but not benzodiazepines), carbamazepine, rifampin and griseofulvin induce the metabolism of oral anticoagulants. However, short-term use may be made during convalescence for the sense of wellbeing and improvement in appetite caused by such treatment. The region that has undergone depolarization remains momentarily in a refractory state.

Latanoprost (a prostaglandin analogue) would be a more suitable antiglaucoma drug for this patient. While majority of asexual schizonts are killed by chloroquine and the fever subsides, some survive and multiply to cause fever again. Accordingly, in clinical trials, ivabradine has been found to improve exercise tolerance in stable angina and reduce angina frequency. However, the distinctive feature is its high activity against a variety of anaerobes, especially Bact. Methylxanthines: Theophylline (anhydrous), Aminophylline, Choline theophyllinate, Hydroxyethyl theophylline, Theophylline ethanolate of piperazine, Doxophylline. Tachycardia and hypotension are prominent at doses which suppress uterine contractions. Increased risk of bleeding due to concurrent use of antiplatelet drugs (aspirin, clopidogrel) with anticoagulants (warfarin). Such studies determine how humans will metabolize a particular drug and, to a limited extent, predict the rate of metabolism. Oral dosage forms of the triptans are the most convenient to use but may not be practical in patients experiencing migraine-associated nausea and vomiting, for whom injectable and nasal spray formulations are useful. Deflazacort the glucocorticoid potency of this newer steroid is somewhat less than of prednisolone, but it lacks mineralocorticoid activity. During biotransformation the disulfide bonds are reduced-A and B chains are separated. Anorexia, vomiting and diarrhoea are the commonest side effects occurring in over 50% patients. The remaining subunits, two copies of, one of, and one of, are shown to surround an internal channel with an outer vestibule and its constriction located deep in the membrane bilayer region. Sexual distress: especially delay or interference with erection, ejaculation and occasionally with orgasm. However, they reduce certain types of spasticity: the site of action being in the basal ganglia or medulla oblongata. Lorazepam is metabolized chiefly by conjugation with glucuronic acid; its t1/2 in plasma is about 14 h. Its oral absorption is slow (making first dose hypotension less likely) and incomplete, but unaffected by food. Although these naturally occurring alkaloids are of great value as pharmacological tools and muscarine has toxicological significance (discussed further in the chapter), present clinical use is restricted largely to the employment of pilocarpine as a sialagogue and miotic agent (Chapter 69). Hence, two routes for termination of effect are available, both of which remain functional in renal failure. This selectivity, however, is not absolute and is lost at high concentrations of these drugs. Because it is fungistatic and not cidal, the newly formed keratin is not invaded by the fungus, but the fungus persists in already infected keratin, till it is shed off. Serum K+ levels are only a rough guide to K+ depletion, because K+ is primarily an intracellular ion. Neurogenic, hypercapnoeic and later hypoxic drives to the respiratory centre are suppressed in succession. Therefore, steady state will be achieved when the electrochemical potentials of a compound on both sides of the membrane become equal. A drug that interacts with a single type of receptor that is expressed on only a limited number of differentiated cells will exhibit high specificity. Adverse effects Because of V2 selectivity, desmopressin produces fewer adverse effects than vasopressin, lypressin or terlipressin. As a result high frequency discharges are inhibited with little effect on normal low frequency discharges which allow Na+ channels to recover even when their inactivation is prolonged.

Synergistic prolongation of postantibiotic effect has also been demonstrated for combinations of -lactams with an aminoglycoside, and by addition of rifampin to a variety of antibiotics. Carvedilol and nebivolol on oxidative stress-related parameters and endothelial function in patients with essential hypertension. Estrogens benefit by suppressing ovarian production of androgen by inhibiting Gn release from pituitary. Ocular manifestations include marked miosis, ocular pain, conjunctival congestion, diminished vision, ciliary spasm, and brow ache. It permeates the outer layers of the cell wall of gram-negative bacteria and inhibits the periplasmically located -lactamase. Ofloxacin is relatively lipid soluble; oral bioavailability is high, and higher plasma concentrations are attained. Chemotactic factors are produced granulocyte migration into the joint; they phagocytose urate crystals and release a glycoprotein which aggravates the inflammation by: (i) Increasing lactic acid production from inflammatory cells local pH is reduced more urate crystals are precipitated in the affected joint. Dexamethasone (which has to be given) also lowers praziquantel blood levels, but increases albendazole absorption. Though, it does not directly inhibit the helminth Dracunculus medinensis, extraction of the worm from under the skin is facilitated. In general, the more potent nondepolarizing blockers have a longer onset of action. The functions of autophagy are to remove cell contents that are damaged and provide cells with substrates for energy and biosynthesis under conditions of stress and starvation. Streptomycin has the lowest nephrotoxicity among aminoglycosides; probably because it is not concentrated in the renal cortex. Drug interactions always should be considered when unexpected responses to drugs occur. Mechanism of action All -lactam antibiotics interfere with the synthesis of bacterial cell wall. Anticholinergic: dry mouth, bad taste, constipation, epigastric distress, urinary retention (especially in males with enlarged prostate), blurred vision, palpitation. Overdose of pethidine produces many excitatory effects-tremors, mydriasis, hyperreflexia, delirium, myoclonus and convulsions. Irinotecan is primarily indicated in metastatic/advanced colorectal carcinoma; also in cancer lung/cervix/ ovary and stomach. A small but important subgroup of striatal neurons consists of interneurons that connect neurons within the striatum but do not project beyond its borders. Prednisolone appears safer than dexa/ beta methasone, because it is metabolized by placenta, reducing foetal exposure. Megaloblastic anaemias due to: (a) Nutritional folate deficiency; manifests earlier than vit B12 deficiency. The other important general points are: the 3 drugs in the regimen should belong to at least 2 different classes. K+ is excreted in faecal water by exchange with Na+, as well as by secretion into mucus and in desquamated cells. Estrogen antagonist in breast and blood vessels, but agonist in uterus, bone, liver and pituitary. Apparently, a longer latent period of onset of marrow aplasia is associated with higher mortality. Members of the family include receptors for circulating steroid hormones such as androgens, estrogens, glucocorticoids, thyroid hormone, and vitamin D. It also permits faster water absorption, precludes risk of hypernatremia and is cheaper. Bronchospasm induced by allergens, irritants, cold air and exercise may be attenuated. Moreover, larger particles settle on the walls of the spacer reducing the fraction that deposits in the throat and is later swallowed.

Erlotinib It is similar to gefitinib in action, pharmacokinetics, adverse effects and efficacy in a subtype of non-small cell lung cancer. However, rifampin given with ciprofloxacin prevents development of resistance to the latter by Staph. Tyrosine-protein kinase inhibitors Imatinib It is the first selectively targeted drug to be introduced for treatment of a malignancy. It is contraindicated during pregnancy, febrile illness and in untreated tuberculosis patients. Structure of the human M2 muscarinic acetylcholine receptor bound to an antagonist. At baseline (black and green tracings), there is no difference in computed action potential duration. Anaerobic bacterial infections They occur mostly after colorectal or pelvic surgery, appendicectomy, etc. If pregnancy occurs during use of hormonal contraceptives-it should be terminated by suction-aspiration, because the risk of malformations, genital carcinoma in female offspring and undescended testes in male offspring is increased. Subjected to stress, these patients may go into acute adrenal insufficiency leading to cardiovascular collapse. Weight gain in general may induce deleterious lipid changes; the evidence indicates that antipsychotic-induced hypertriglyceridemia is a weight-independent adverse event that occurs within weeks of starting an offending medication and resolves within 6 weeks after medication discontinuation. Pharmacokinetics Oral bioavailability of procainamide is about 75%, peak plasma concentration occurs in 1 hour. Retinoic acid (vit A acid) Retinoic acid has vit A activity in epithelial tissues and promotes growth, but is inactive in eye and reproductive organs. Risk of tendon damage is higher in patients above 60 years of age and in those receiving corticosteroids. The synthesis of several compounds of much greater toxicity than parathion, such as sarin, soman, and tabun, was kept secret by the German government. The Vascular theory holds that initial vasoconstriction or shunting of blood through carotid arteriovenous anastomoses produces cerebral ischaemia and starts the attack. It is well absorbed orally, 99% protein bound, metabolized and excreted both in urine and bile. The agonist-binding site is intimately coupled with the ion channel; in the Nm, simultaneous binding of two agonist molecules results in a rapid conformational change that opens the channel. The third generation cephalosporins alone or with an aminoglycoside are favoured for this purpose. Spiramycin this macrolide antibiotic, though available for more than a decade, has been employed only sporadically. Ultrarapid elimination Triazolam Very potent, peak effect occurs in < 1 hour; good for sleep induction but poor for maintaining it. Gastrointestinal intolerance, rashes, granulocytopenia, myalgia and uveitis have been reported with rifabutin. Enzyme preparations containing an antispasmodic or a laxative and fixed dose combinations of pancreatine or pancrelipase containing amylase, protease and lipase with any other enzyme are banned in India. It is claimed to have selective anxiolytic action, but the accompanying sedation is quite marked. Use for spinal anaesthesia of long duration has declined after the availability of bupivacaine. Niacin (vit B3) Chemistry and source Niacin refers to Nicotinic acid as well as Nicotinamide-pyridine compounds, initially termed pellagra preventing factor. It is a preferred drug for mild intestinal/asymptomatic amoebiasis, and is given after or along with any tissue amoebicide to eradicate cysts. Although many attempts have been made to separate the anxiolytic actions of benzodiazepines from their sedative-hypnotic effects, distinguishing between these behaviors is problematic. Antithyroid drugs do not affect release of T3 and T4-their effects are not apparent till thyroid is depleted of its hormone content. It may be combined with piperacillin or a third generation cephalosporin for serious infections. Anaemia: Ascorbic acid enhances iron absorption and is frequently combined with ferrous salts (maintains them in reduced state). Signaling Pathways and Drug Action Throughout this text, cellular signaling pathways figure prominently in explaining the actions of therapeutic agents.
