Improved arterial blood gas levels (normal values: PO2 80 to 100 mm Hg; PCO2 35 to 45 mm Hg; pH, 7. Decreased incidence and severity of acute attacks of bron- chospasm with chronic administration of drugs 3. With adrenergic bronchodilators, observe for tachycardia, These signs and symptoms result from cardiac and central nervous arrhythmias, palpitations, restlessness, agitation, insomnia. With ipratropium, observe for cough or exacerbation of Ipratropium produces few adverse effects because it is not ab- symptoms. With xanthine bronchodilators, observe for tachycardia, Theophylline causes cardiac and CNS stimulation. Convulsions arrhythmias, palpitations, restlessness, agitation, insomnia, occur at toxic serum concentrations (>20 mcg/mL). Theophylline also stimulates the chemoreceptor trigger zone in the medulla oblongata to cause nausea and vomiting. With inhaled corticosteroids, observe for hoarseness, cough, Inhaled corticosteroids are unlikely to produce the serious adverse throat irritation, and fungal infection of mouth and throat. With leukotriene inhibitors, observe for headache, infection, These drugs are usually well tolerated. A highly elevated ALT and nausea, pain, elevated liver enzymes (eg, alanine aminotrans- liver dysfunction are more likely to occur with zileuton. With cromolyn, observe for dysrhythmias, hypotension, Some of the cardiovascular effects are thought to be caused by the chest pain, restlessness, dizziness, convulsions, CNS depres- propellants used in the aerosol preparation. Drugs that increase effects of bronchodilators: (1) Monoamine oxidase inhibitors These drugs inhibit the metabolism of catecholamines.

With anticholinergic drugs, observe for atropine-like effects, such as: (1) Tachycardia and palpitations These effects may occur with usual therapeutic doses but are not likely to be serious except in people with underlying heart disease. The drug has anti- histaminic and anticholinergic properties, and sedation is attributed to the antihistamine effect. With levodopa, observe for: (1) Anorexia, nausea, and vomiting These symptoms usually disappear after a few months of drug ther- apy. They may be minimized by giving levodopa with food, gradu- ally increasing dosage, administering smaller doses more frequently or adding carbidopa so that dosage of levodopa can be reduced. It can be minimized by arising slowly from supine or sitting positions and by wearing elastic stockings. People with pre-existing coronary artery disease may need a beta-adrenergic blocking agent (eg, propranolol) to counter- act these effects. Carbidopa may heighten this adverse effect, and there is no way to prevent it except by decreasing levodopa dosage. Many people prefer dyskinesia to lowering drug dosage and subsequent return of the parkinsonism symptoms. With amantadine, observe for: (1) CNS stimulation—insomnia, hyperexcitability, ataxia, Compared with other antiparkinson drugs, amantadine produces dizziness, slurred speech, mental confusion, hallucinations few adverse effects.

Late in the afternoon buy generic benicar 20mg, after the faculty members had been picked up, each from a different town, we flew south down the branching and con- verging waters of the rivers north of Mobile. Te waters glistened and broadened, eventually forming the backwaters and then the expanse of Mobile Bay that stretched more than thirty miles to the Gulf of Mexico. Far off in the distance to the east, we saw the jut of land called Fairhope. Te pilot, something of a daredevil, then turned the plane into a sharply descending dive, swooping to within fifty feet of the waters of the bay. Shortly, we neared the rows of sticklike piers in front of hundreds of clapboard summer homes. We aimed at the pier where we knew our wives were gathered to wave at us as we returned from our day in the field. Just as we roared over the pier, the plane abruptly rose and tipped its wings to the gathering below. Te wives waved back, signaling a weekend of parties, sun, boat rides, and seafood. In 1894, a group of farmers and citizens from Iowa formed a commune and colony in what is now Fairhope. Supporters of a na- 95 96 Symptoms of Unknown Origin tional single-tax movement, their dream was to have a single tax and live in a community with joint ownership of the land. Tey wrote back to family in Iowa, Tere is a fair hope that our experi- ment will work—hence the name of the town. In the long run, the single-tax movement failed, but the community thrived. I wanted to find out what really goes on between patients and physicians.
