Zinc deficiency may play a role in the etiology of anorexia nervosa. The symptoms of anorexia nervosa and zinc deficiency are similar in a number of respects, e.g., weight loss, loss of appetite, amenorrhea in females, impotence in males, nausea and skin lesions. In both conditions females under 25 are most at risk. Stress, estrogen and dietary habits may also be involved in the complex of factors which create or exacerbate a zinc deficiency and result in anorexia nervosa. It is proposed that effectiveness in the treatment of anorexia nervosa.

Diuretics can result in various undesired biochemical changes, such as impotence, skin rashes, nausea, dizziness and lethargy as well as subjective side effects. The side effects are mostly predictable, their effects depending on both the circulatory blood volume and on the transport of water and solute in the renal tubules. Two of the commonest side effects are mild hypovolaemia, when any diuretic is used, and mild hypokalaemia when the non-potassium-sparing diuretics, such as thiazides and frusemide are used. Its occurrence is dose dependent and can be corrected by potassium supplements, but potassium-retaining diuretics, which also correct the often associated fall in serum magnesium, are preferable. Many reports link hypokalaemia with cardiac arrhythmias, but some dispute this association in the absence of the concomitant use of digoxin. Hyponatraemia rarely occurs, but can be life threatening. Calcium excretion is markedly reduced, but unlike other electrolyte disturbances from diuretics, this may be valuable: some suggest diuretics have an anti-osteoporotic action. Diuretics increase glucose and insulin resistance and should be used sparingly in diabetics. They rarely cause a non-ketotic hyperosmolar coma. Urate is raised, but clinical gout is not common. Cholesterol elevation has been reported in some studies, but long-term studies indicate that lipid changes are minor. Other rare side effects are not predictable from their pharmacological actions and these include the occurrence of skin rashes, thrombocytopenia, pancreatitis and interstitial nephritis; and ototoxicity from frusemide.

In 984 patients with generalized anxiety disorder who received buspirone in double-blind studies, the incidence of drowsiness (9 percent) did not differ significantly from that (10 percent) reported in 334 patients who received placebo. A probability value of p less than or equal to 0.10 was the criterion for significance. The incidence of drowsiness in buspirone-treated patients was significantly less than that in each of the groups receiving diazepam (32 percent), clorazepate (26 percent), lorazepam (58 percent), or alprazolam (43 percent). The side effects that did occur significantly more frequently in the buspirone group than in the placebo group were dizziness (9 percent versus 2 percent), headache (7 percent versus 2 percent), nervousness (4 percent versus 1 percent), light-headedness (4 percent versus less than 1 percent), diarrhea (3 percent versus less than 1 percent), paresthesia (2 percent versus less than 1 percent), excitation (2 percent versus less than 1 percent), and sweating/clamminess (1 percent versus 0 percent). The severities of these effects were predominantly rated as only mild or moderate. Fatigue occurred less frequently in buspirone-treated patients than in those receiving any of the benzodiazepines, and weakness occurred more frequently in diazepam-treated patients. Depression occurred less frequently in buspirone-treated patients than in those receiving clorazepate, diazepam, or lorazepam. Impotence occurred only in clorazepate- and lorazepam-treated patients. Decreased libido occurred more frequently in diazepam-treated patients, whereas increased libido was more frequent in clorazepate-treated patients. Nausea was reported more frequently in buspirone-treated patients than in those receiving clorazepate, diazepam, or alprazolam; diarrhea occurred more frequently in the buspirone group than in the diazepam group. The mean daily doses of the various treatments were buspirone, 20 mg; diazepam, 20 mg; clorazepate, 24 mg; lorazepam, 3 mg; and alprazolam, 1.5 mg. In an open-field study in West Germany involving 5,414 patients, gastrointestinal-related complaints were the most frequently reported side effects.

To evaluate interactions between the opiate and adrenergic systems in healthy humans, concomitant administration of the opiate antagonist, naloxone hydrochloride, and the alpha 2-adrenergic receptor antagonist, yohimbine hydrochloride, was compared with the administration of placebo and of each drug separately. A synergistic effect of the combination (larger than the sum of the effects of the two drugs separately) was observed on subject ratings of nervousness, anxiety, tremors, palpitations, nausea, hot and cold flashes, and increased plasma cortisol concentrations. In addition, following the combination, each of the male subjects studied reported a full penile erection lasting at least 60 minutes, an effect not reported when each drug was given separately. These results demonstrate that interactions between the opiate the adrenergic systems have important implications for our understanding of the cause and treatment of anxiety disorders and male impotence.

Apomorphine (Apo), a short acting dopamine (DA) receptor agonist induces penile erections in normal subjects. The erectile response to one or more doses of Apo HCl (0.25, 0.5, 0.75, 1.0 mg sc) or placebo was investigated in eight impotent subjects and penile tumescence monitored using a mercury strain gauge and strip chart recording. Four patients showed a full erection with Apo and one a partial response. Distressing side effects (nausea, sweating) were associated with non-response or partial response. Three responders to Apo were treated with low doses of the long acting DA receptor agonist, bromocriptine (2.5-3.75 mg/d po); all three showed complete recovery of erectile function within two weeks. A subgroup of impotent patients may have impaired central DA function. Testing with Apo may provide a diagnostic and predictive test to identify such patients who may respond to treatment with low doses of bromocriptine or other DA receptor agonist.

We conducted a 10-center, double-blind trial to compare the efficacy and toxicity of four antiepileptic drugs in the treatment of partial and secondarily generalized tonic-clonic seizures in 622 adults. Patients were randomly assigned to treatment with carbamazepine, phenobarbital, phenytoin, or primidone and were followed for two years or until the drug failed to control seizures or caused unacceptable side effects. Overall treatment success was highest with carbamazepine or phenytoin, intermediate with phenobarbital, and lowest with primidone (P less than 0.002). Differences in failure rates of the drugs were explained primarily by the fact that primidone caused more intolerable acute toxic effects, such as nausea, vomiting, dizziness, and sedation. Decreased libido and impotence were more common in patients given primidone. Phenytoin caused more dysmorphic effects and hypersensitivity. Control of tonic-clonic seizures did not differ significantly with the various drugs. Carbamazepine provided complete control of partial seizures more often than primidone or phenobarbital (P less than 0.03). Overall, carbamazepine and phenytoin are recommended drugs of first choice for single-drug therapy of adults with partial or generalized tonic-clonic seizures or with both.

In the United States, the drugs most commonly used to treat peptic ulcer disease are antacids and the H2-receptor antagonists cimetidine and ranitidine. Other available agents include anticholinergics and the coating agent sucralfate. Investigational drugs such as colloidal bismuth, carbenoxolone, prostaglandins, the tricyclic compound pirenzepine, and substituted benzimidazoles are not available for use in the United States. Most of the commercially available and investigational compounds have similar efficacy; therefore the optimal drug may be the one associated with the fewest adverse effects and the most convenient dosing regimen. Cimetidine causes a small number of adverse effects, including neuropsychiatric disorders, gynecomastia, impotence, loss of libido, elevation of serum creatinine and serum transaminases concentrations, and drug interactions. Some of these reactions have been of clinical significance. Presently, there are rare reports of gynecomastia, bradycardia, inhibition of acetylcholinesterase, headache, lethargy, diarrhea, and rash in patients receiving ranitidine. Antacids can produce either diarrhea or constipation and have been associated with low serum phosphorus concentrations, and metabolic alkalosis. Anticholinergics, especially in elderly or debilitated patients, can cause central nervous system disorders, intestinal atony, or urinary retention. Sucralfate may cause constipation, diarrhea, nausea, and headache. The investigational agents have their own side effect profiles. The adverse effects of anticholinergics make them unattractive therapeutic choices, and antacids and sucralfate have inconvenient dosing requirements compared with some equally efficacious alternatives. In addition, clinical experience with sucralfate in the United States is limited. The safety record of cimetidine is admirable. As clinical experience with ranitidine increases, currently unrecognized adverse effects may be reported. However, based on current data, ranitidine is as effective as cimetidine and is associated with a lower incidence of side effects.

More than 1200 patients who received pindolol for the treatment of hypertension, angina pectoris, and various arrhythmias in studies conducted in the United States were included in the New Drug Application submitted to the FDA. Nearly 1000 of these patients received pindolol as monotherapy. The side effects reported were generally transient and of mild or moderate severity. The most frequently reported side effects seen after pindolol administration, compared to those seen after placebo, were in decreasing order of incidence: headache, dizziness, insomnia, muscle pain, fatigue, weakness, nervousness, joint pain, edema, nausea, and muscle cramps. Other side effects that occurred more frequently with pindolol than with placebo but at a rather low incidence induced weight gain, bizarre dreams, visual disturbances, lethargy, and diarrhea. Nasal congestion, throat discomfort, nocturia, impotence, pruritus, anxiety, hypotension, bradycardia, and heart failure occurred only rarely. Of the 323 patients who received pindolol alone for the treatment of mild to moderate hypertension, only 20 (6.2%) were withdrawn from the study because of side effects. Overall, 3.4% of the patients treated with pindolol were withdrawn because of side effects, most of which involved the central nervous system, that is, insomnia, anxiety, dizziness, and headache. However, a few patients manifested some edema and weight gain while receiving pindolol alone. Review of the side effects data did not reveal a tendency for the incidence of side effects to be dose related. One placebo-controlled, double-blind study designed to evaluate the fixed dosages of 15, 30, and 60 mg in the treatment of mild to moderate hypertension suggested that only the incidences of insomnia and nervousness increased with increasing doses. However, these side effects were generally transient and of mild or moderate severity. The evidence indicates that pindolol has an acceptable safety profile and that any side effects that appear are generally well tolerated and disappear with continued treatment.

Timolol has become so populat with ophthalmologists that it is prescribed 44% of the time when an anti-glaucoma drop is needed. This popularity is due to its newness and the publicity it has received, its effectiveness in most types of glaucoma, and the apparent scarcity of side effects. This paper looks at the first 489 patients treated with timolol at Wills Eye Hospital and the side effects encountered. These include blurring of vision, burning and pain, bradycardia and heart failure, hallucinations, dilated pupils, headaches, dizziness, hypotony, allergy, asthma, impotence, drowsiness, anxiety, emotional lability, and nausea.

The chemistry, pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage of sotalol hydrochloride are reviewed. The chemical name of sotalol hydrochloride is 4'-[1-hydroxy-2-(isopropylamino)ethyl]methanesulfonanilide monohydrochloride. Sotalol is a class III antiarrhythmic that prolongs the action potential and refractoriness of cardiac tissue and has potent nonselective beta-blocking activity. Sotalol is well absorbed after oral administration. The pharmacokinetics of sotalol can be described by an open, linear, two-compartment model. The drug is eliminated primarily by the kidneys; mean elimination half-life is 12 hours. Sotalol has been found to be effective in controlling life-threatening ventricular arrhythmias, including sustained ventricular tachycardia, ventricular fibrillation, and premature ventricular complexes. Although sotalol has FDA-approved labeling for use in the treatment of ventricular arrhythmias only, it is also effective against a variety of supraventricular arrhythmias. Noncardiac adverse effects include fatigue, impotence, depression, headache, nausea, diarrhea, and increased triglyceride levels. Cardiovascular adverse effects include atrioventricular block, bradycardia, hypotension, exacerbation of heart failure, and polymorphic ventricular tachycardia. Overall, 11-21% of patients experience adverse effects; 6-18% of these patients have reactions serious enough to warrant the discontinuation of sotalol therapy. The initial dosage of oral sotalol hydrochloride in adults is 80 mg twice daily or 160 mg once daily; the dosage can be increased every three to four days in increments of 40-160 mg/day to a maximum of 480 mg/day. Sotalol is useful in the control of intractable, life-threatening ventricular arrhythmias, as well as a variety of supraventricular arrhythmias, in patients who do not respond to or are intolerant of more conventional antiarrhythmics.
