A double-blind comparison of the efficacy and safety of droperidol (5 mg), hydroxyzine HCl (50 mg), diazepam (5 mg), and saline placebo, given concomitantly with meperidine (50 or 75 mg) for preoperative medication, was conducted in 280 female patients scheduled for minor gynecologic procedures. Droperidol proved to significantly superior to the other study drugs in alleviating apprehension (83% of patients calm versus 54, 46, and 34% for hydroxyzine, diazepam, and placebo, respectively). Some drowsiness, occurred in 68 percent of the droperidol-treated patients versus 31, 30, and 21 percent of the other 3 groups, respectively. Global evaluations were consistent with these findings. No clinically significant changes were observed in vital signs in any of the study-drug groups. Adverse reactions were unremarkable in all groups. Significantly less nausea occurred with droperidol than with other treatments, and signficantly less vomiting occurred with droperidol or hydroxyzine. Significantly fewer patients in the droperidol group than in the diazepam group required postoperative antiemetics.

One of a novel series of compounds (AMAPS or arylmethylaminopropanediols), 773U82-HCl has shown significant antitumor activity in in vitro and in in vivo tumor systems, but has less animal CNS toxicity than the lead compound in the same series (crisnatol). This study was designed to evaluate the pharmacokinetics, qualitative and quantitative toxicities of 773U82-HCl and to determine the recommended phase II dose (MTD) of 773U82-HCl given as a short infusion daily for 3 days every 3 weeks. Twenty-nine patients with refractory malignancies received 79 courses over 9 dose levels during this study. Doses ranged from 50 to 1060 mg/m2/d x 3 days. Due to the possibility of local hemolysis with concentrations > 1.5 mg/ml, drug was administered in solutions containing < or = 1.5 mg/ml. Because large volumes were needed at the higher dose levels, the infusion duration was increased from 2 hours to 4 hours. Mild to moderate nausea, vomiting, fatigue, dizziness and headaches were observed. Myelosuppression was the dose limiting toxicity. The recommended phase II dose and schedule was determined to be 800 mg/m2/d x 3d every 3 weeks. 773U82-HCl plasma concentration-time data were analyzed using a two-compartment pharmacokinetic model. The t1/2 beta averaged 6 hours and the total body clearance was 75.9 L/hr/m2. The volume of distribution (Vdss) was large, averaging 470 L/m2.

One hundred eighteen patients, 77 men and 23 women ranging in age from 18 to 70 years of age, admitted to an inpatient facility in Central New York were administered buspirone HCl for treatment of the alcohol withdrawal syndrome. Although one patient had an unwitnessed seizure, none of the subjects required discontinuance of buspirone HCl because of symptoms of dizziness, nausea, headache, nervousness, or lightheadedness, typical side effects described by the manufacturer. All but one of the individuals given buspirone HCl for alcohol detoxification completed that phase of treatment within six days in a manner which effectively controlled their withdrawal symptoms. The findings were suggestive of an important role for buspirone HCl in the detoxification of the alcohol-dependent patient using a pharmacologic agent other than traditional medications such as benzodiazepines, phenobarbital, beta blockers, magnesium sulphate, or clonidine.

Bulfield and others found X-linked muscular dystrophic (mdx) mouse by screening C57 BL/10 mice. The serum CK and PK are high in mdx mice, and they develop muscle degeneration 10-15 days after birth. The regeneration is vigorous in mdx mice and almost all the muscle fibers are replaced by regenerated fibers by 60 days after birth. Although mdx mice have been developed as a model for X-linked muscular dystrophy we have found that myotonic bursts are recorded when a glass microelectrode is inserted into the muscle fibers of hemidiaphragm preparations of mdx mice. Insertion myotonia is ceased by addition of the Na channel blocker tetrotoxin. Myotonia is not reduced, nor ceased by lowering the extracellular Ca to 1/15 of the volume of ordinary Tyrode's solution. Calcium antagonist, nicardipine at the dose of 10(-7), and 10(-6)M/L do not reduce myotonic bursts. Higher dose of nicardipine up to 2 x 10(-5)M/L abolished myotonic bursts. These results indicate that myotonic bursts are related to muscle membrane abnormalities, and each action potential occurs through Na channel, but not through Ca channel Higher dose of calcium antagonist can abolish myotonia by affecting Na channel in addition to their primary effects of Ca channel. The clinical effects of the Ca antagonist for myotonia was reported in one study. Since previous medications for myotonia including quinine HCl, procaine amide, diphenylhydantoin, and carbamazepine have some side effects such as tinnitus, headache, nausea, cardiac blocks, and bone marrow suppression, Ca antagonist may be used as a safe therapeutic drug for myotonia.

The influence of food on release of drug from a modified release capsule of bromocriptine 5 mg (Parlodel SRO) and a conventional formulation of bromocriptine 5 mg has been studied in 8 healthy male volunteers. Both formulations produced objective and subjective effects, such as orthostatic reactions, nausea, dizziness, vomiting and nasal congestion. The modified release capsule caused fewer side-effects than the normal capsule. Both formulations had less cardiovascular effect in the fed than in the fasting state. There was no significant difference between the normal and the modified release capsules taken fasting or after a meal in terms of the AUC extrapolated to infinity. The relative bioavailability of the 5 mg modified release capsule was 84.6% of the normal capsule under fasting conditions and 107.5% after food. In contrast to the virtually unchanged extent of absorption, the rate of absorption was markedly affected by food, especially from the conventional capsule. The mean time of 50% absorption increased from 1.06 h (fasting) to 3.2 h (fed), whereas for the modified release capsule food mainly resulted in an increased lag time of absorption. The almost instantaneous dissolution of bromocriptine from the normal capsule in vitro (both in HCl and fasting human gastric juice) and the delay of absorption after a meal in vivo suggest that the rate limiting step in absorption of the normal capsules is delivery of released drug from the stomach to the small intestine, which is delayed by food. Both the modified release 5-mg capsule and the normal 5-mg capsule showed extended suppression of prolactin over 36 h, in all subjects, both fasted and after a meal.

To investigate the tolerance and efficacy of moricizine HCl, single-blind placebo-controlled trials were conducted. The early protocols involved patients hospitalized for 14 days, and daily Holter monitoring was used to document efficacy and the degree of spontaneous variability of ventricular premature complexes (VPCs). Moricizine HCl was given orally from 2.9 to 15.3 mg/kg 3 times daily. Patients with lethal ventricular arrhythmias were excluded. Additional outpatient trials were conducted to define long-term efficacy and safety. A dose-response relation between moricizine HCl and the percentage of reduction in frequency of benign or potentially lethal ventricular arrhythmias was documented. Eighty-five percent of patients achieved a reduction in VPCs greater than 75% with daily dosages ranging from 10.1 to 15 mg/kg. This corresponded to a 95% decrease in mean frequency of VPCs. Long-term studies demonstrated no evidence of compromise in left ventricular function, and the proarrhythmic rate was only 2%. Symptomatic side effects were mild and usually well tolerated. Nausea, the most common, occurred in 11% of patients and dizziness in 9%. These results indicate that moricizine HCl is an effective and well-tolerated antiarrhythmic agent.

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.

A group of 71 women between 11-20 weeks of gestation who desired termination of pregnancy and had no contraindications for prostaglandin (PG) administration were given complete physical and gynecological examinations; hemoglobin was estimated and urinalysis was done. They were then given orally 2 tablets of Lomotil (diphenoxylate HCl 2.5 mg + atropine sulphate 0.025 mg) and 1 tablet of Stemetil (Prochlorperazine 5 mg). They were then given 15 (S) 15 methyl PGF2alpha intravenously at the dose level of 1 mcg/min. 61 subjects (85.9%) aborted within 30 hours. At regular intervals pulse rate, blood pressure, uterine pain, nausea, vomiting, diarrhea, temperature, and respiratory rate were measured and any other side effects were recorded. The mean induction abortion interval was 15.65 hours, the mean number of episodes of vomiting and diarrhea was 0.9 and 0.6 respectively. This study compared well with the intramuscular route of administration with a higher rate of complete abortions and lower rate of side effects. The latter is explained on the basis of smaller amounts of the drug being infused at a slower rate. Disadvantages include confinement to bed, discomfort, and need of constant supervision. Compared with intraamniotic and extraamniotic case studies, the latter are invasive procedures while the intravenous method is not. Also, the intravenous route allows for adjusted drug dosage and stopping the procedure in the event of an undesirable reaction.

The effect of daily dietary supplements of 30 gm of arginine HCl for 7 days on peripheral blood lymphocyte (PBL) mitogenic reactivity in vitro was measured in 21 healthy human volunteers. Arginine significantly increased stimulation indices of PBL following concanavalin A (Con A) (57.9 +/- 11.4 versus 216.9 +/- 46.6, P less than 0.01) and phytohemagglutinin (PHA) (84.1 +/- 12.8 versus 307.0 +/- 59.4, P less than 0.001) stimulation in a microculture assay utilizing RPMI 1640 medium supplemented with 10% heat-inactivated autologous serum. Similar enhanced blastogenesis was observed using medium supplemented with 10% heat-inactivated pooled AB normal human serum. In six volunteers studied following 3 days of similar arginine supplementation, blastogenic responses of their peripheral blood lymphocytes were already significantly enhanced, although not as greatly as after 7 days. Arginine had no effect on total peripheral blood lymphocyte counts and on T- and B-cell ratios. The effects of supplemental dietary arginine could not be duplicated in vitro by increasing the arginine concentration in the culture medium. Furthermore, dietary arginine supplementation did not increase cell viability in culture. Minimal side effects were noted, such as nausea or diarrhea, which responded to lowering the dose ingested at one time. No deleterious effects were noted on liver function test results. We conclude that supplemental dietary arginine is a safe nutritional stimulator of lymphocyte immune reactivity in healthy human beings.

Nine pale perspiring drug addicts with drowsiness, nausea, headache, normal blood pressure and marked sinus bradycardia with premature ventricular beats were seen at the Casualty Department soon after alleged i.v. cocaine administration. Eight were treated with atropine, as the bradycardia suggested intoxication with a parasympathomimetic compound. Seven were discharged in good condition after a few hours' observation. One patient developed a blood pressure of 150/120 mmHg after atropine. Subsequently, a hemiparesis was found and an intracerebral haematoma was evaluated at surgery. Another patient was admitted forthwith to the CCU. He did not receive any medication and recovered within two days. Urinalysis of these two patients disclosed contents of naphazoline, a powerful alpha-adrenergic agent. Samples of the alleged cocaine contained 97% naphazoline HCl. A conscious rabbit was injected with naphazoline and thereafter with atropine. I.v. naphazoline doubled mean arterial pressure (MAP) and reduced heart rate (HR) from 167 to 30 beats/min. Atropine doubled HR, but caused a marked rise in MAP, too, stressing the adverse effects of atropine in these cases. When confronted with patients after alleged cocaine abuse, the role of substitute drugs, especially alpha-adrenergic compounds, should be considered as this should influence the therapeutic approach.
