Examples of enhanced functions include increased migration of leukocytes to antigens, increased antibody toxicity, and increased phagocytosis. The most serious adverse effect of tolcapone is liver failure, which may be fatal. Proper timing of chamber contractions is made possible by the cardiac conduction system, a branching network of specialized cardiac muscle cells that sends a synchronized, electrical signal across the myocardium. Depression is one of the oldest known mental health conditions and one of the most frequently diagnosed. Have the client increase intake of caffeine by consuming cola products, coffee, or tea to counteract the depressive effect. Off-label indications for atenolol include ethanol withdrawal, migraine prophylaxis, and unstable angina. Almotriptan (Axert): Almotriptan was approved as an oral antimigraine drug in 2001.

Be aware that the administration of this drug is an emergency situation to prevent opioid-induced respiratory arrest. It is an ancient drug, used for centuries in India as an herbal tea to produce sedation and calm the nerves. As the disease stabilizes and the desired degree of anticoagulation has been achieved, the patient is gradually switched to oral anticoagulants, with careful monitoring of appropriate coagulation laboratory values. The remaining Class I drugs are more specific, and indicated only for life-threatening ventricular dysrhythmias. In the 1950s, health care providers called antibiotics "miracle drugs" and predicted that all infectious disease would one day be eliminated. Ethosuximide (Zarontin) Classification: Therapeutic: Antiepileptic drug Pharmacologic: Succinimide, neuronal calcium channel modulator Therapeutic Effects and Uses: Ethosuximide is the only drug in this class that is commonly prescribed. Drug Interactions: Hepatitis B immunoglobulin should not be administered in the same syringe or at the same site as the vaccine because it can impair the development of immunity from the vaccine.

Drug Interactions: Use of tramadol concurrently with carbamazepine or certain antidepressants increases the risk of seizures. Because constipation is common, especially in older adults, an increase in dietary fiber intake is indicated. Lifespan and Diversity Considerations: Monitor the older adult for the development of dizziness related to possible hypotension. Oseltamivir is the only antiviral approved to treat both A and B influenza viruses in patients 12 months of age or older. Lifespan and Diversity Considerations: Monitor older adults for bleeding more frequently because normal hepatic changes related to aging may prolong the action of the drug and increase the risk of bleeding. Morphine is used to provide effective analgesia, and naltrexone, which has no pharmacologic activity of its own, is included to block some of the side effects of morphine and to prevent product misuse. Adverse effects may include nausea, vomiting, weakness in the legs, myalgia, numbness and tingling in fingers and toes, anginalike pain, and tachycardia. It is important that disinfecting agents with heavy metal content not be used to disinfect the skin prior to the insertion of the epidural catheter because these have been associated with swelling and edema. During a migraine, the amount of serotonin in the brain declines and the vessels dilate; nerves surrounding the dilated vessels become inflamed. Drug Interactions: Because very little of the drug is absorbed, no clinically significant drug interactions occur.

In essence, the thrombolytics simply accelerate the normal process of clot removal in the body. Severe myopathy and rhabdomyolysis are rare, although they are serious adverse effects of the statins. Ibuprofen inhibits inflammatory cell chemotaxis, decreases the release of superoxide radicals, and increases the scavenging of these products at the inflammatory sites. Beta-adrenergic blockers or sublingual nitrates may be administered concurrently to reduce the possibility of reflex tachycardia in patients with angina pectoris. The patient may report having an unpleasant taste, a coated tongue with discoloration, vomiting, anorexia, diarrhea with flatulence, or paralysis. Treatment is sometimes delayed, however, because the initial symptoms are nonspecific and may resemble the common cold or flu.

This is due to the rapid release of calcium ions in muscle cells, which produces hypermetabolism and intense muscle rigidity. Just as important, erythropoietin also stimulates the production of hemoglobin (Hgb), which is required for a functional erythrocyte. The drug can lower bone mineral density, placing the patient at risk for osteopenia or bone fractures. Cholestyramine may indirectly increase the effects of warfarin by binding to vitamin K, decreasing its absorption and lowering the levels of vitamin K in the body. Because coagulation factors, antibodies, and most other blood proteins have been removed, allergic reactions from albumin are rare.

Classifying drugs only by their susceptible organism, such as an antibacterial, tells us nothing about the properties, actions, or adverse effects of a drug. The drug should be used with extreme caution in patients with chronic or acute renal failure because the drug may accumulate to high levels. For most patients, anticoagulation with aspirin or clopidogrel is sufficient for protection from thromboembolic events. Methylxanthines are agents similar to xanthine, a chemi- Because of differences in metabolism, monitor ethnically diverse patients closely to ensure optimal therapeutic effects of other drugs taken along with this drug.

Ketoconazole should not be given to patients with chronic alcoholism due to the possibility of additive liver damage. This is because health care providers have developed clear rationales for prescribing these drugs to discourage the emergence of resistant strains. Although some of the opioids do indeed cause direct histamine release from mast cells, these types of idiosyncratic reactions do not result in the classic signs of anaphylaxis, thus they are not true allergic reactions. Diuretics can increase the risk of lithium toxicity by promoting sodium loss; the body replaces lost sodium with lithium, which is also a salt. Severe metabolic alkalosis may be reversed by the administration of acidic agents such as ammonium chloride. A slight increase in mortality has been reported with the use of tigecycline, although its cause remains unknown.

Folate deficiency during pregnancy has been linked to neural birth defects such as spina bifida. They produce a more predictable anticoagulant response than heparin because there is less binding of the drug to proteins and macrophages; therefore, less frequent laboratory monitoring is required. In the 1970s, it became increasingly clear that serotonin had a more substantial role in depression than once thought. When possible, pregnant patients are treated after the first trimester to minimize risks to the fetus. In addition to resistance, several other factors have led to a significant decline in the use of sulfonamides. The risk of bleeding returns to normal within 24 hours after the drug has been infused. Black Box Warning: Although rare, hepatotoxicity is a serious and sometimes fatal adverse effect; thus, the patient should be monitored carefully for jaundice, fatigue, elevated hepatic enzymes, or loss of appetite.

Concurrent administration with cimetidine will increase the plasma levels of diazepam. The third major class is named potassium-sparing diuretics, because they have minimal effect on potassium ion (K) excretion. This is because, in myocardial cells, the signal for opening calcium channels is linked to activation of the sympathetic nervous system. From what you learned in Chapter 23, what two drugs are usually combined with the atypical antipsychotics The balance between these two activities appears to account for the decrease in observed adverse effects, relative to other antipsychotic agents. Facilities should be available to provide prompt and accurate serum concentration data. Some studies have suggested that certain antihypertensive drug classes are less effective in African Americans. Mast cells detect foreign agents or injury and respond by releasing histamine, which initiates the inflammatory response within seconds.

He was stabilized with lithium for the manic periods and is also taking valproic acid. Unlike flecainide, propafenone exhibits clinically significant betaadrenergic antagonist activity. Second, the heart and vessels simply weaken over time and, as the average life span of the population increases, more pharmacotherapy will be needed to treat the cardiovascular diseases of older adults. This slow vasopressor response is believed to be responsible for producing a sustained elevation of blood pressure and a gradual decline of renal function. Avoid licorice because large amounts can cause potassium depletion and sodium retention.
