2-Chloro-11-(2-dimethyl-aminoethoxy)dibenzo [b,f]thiepine (zotepine) is a new neuroleptic drug with a chemical structure different from known neuroleptics. The psychopharmacological effects of zotepine in mice, rats and dogs were studied and compared with those of commercially available neuroleptics. Haloperidol and perphenazine were the most active and thioridazine was the least active in hibiting apomorphine-induced gnawing and circling movement, methamphetamine-induced gnawing and circling movement, conditioned avoidance response, motor activity, dopamine-induced pancreatic secretion and apomorphine-induced vomiting. These drugs also had the same order of potency in inducing catalepsy and increasing dopamine turnover and prolactin release. Chlorpromazine, propericiazine and thiothixene were intermediate in potency. Zotepine equalled chlorpromazine in most activities, however, it was clearly less active than chlorpromazine in potentiation of barbiturate sleep and cardiovascular effect.

Chlorpromazine and fluphenazine decanoate were employed to treat aggressive behavior and emesis in a 22-year-old patient with Cornelia de Lange syndrome. Institution of the above neuroleptics, following an unsuccessful trial of diazepam, produced reductions of 95.1 per cent and 37.9 per cent for aggressive behavior and emesis, respectively. Four follow-up observations, occurring at 3-week intervals, revealed maintenance of low rates of aggressive behavior and continued reductions in emesis (mean reduction of 81.5 per cent). These findings are important for their a) inclusion of direct behavioral observation as the data base, and b) initial promising effects of neuroleptics for a rare mental retardation syndrome.

The efficiency of antiemetic drugs was investigated in 36 children with neoplasia (mainly of hematopoietic system) in the course of 83 cycles of chemotherapy. The following antiemetic drugs were investigated: Fenactil (brand of chlorpromazine), Torecan (brand of thienylpromazine maleate), Aviomarin (brand of dimenhydrinate), Decadron (brand of dexamethasone), Primperan (brand of metoclopramid), and placebo. The most efficient was dexamethasone which prevented vomiting in 54% cycles of chemotherapy and diminished their intensity in the remaining cycles. No adverse reactions were noted. Efficacy of Fenactil, Torecan, Aviomarin, and Primperan was similar to that of placebo.

In just-weaned piglets (n = 30, 3-4 weeks) diarrhoea (100%) and vomiting (66%) were provoked by inoculation with transmissible gastroenteritis virus and enterotoxigenic E. coli strains (O149: K91: K88ac; LT, STa and STb enterotoxin positive). This combined infection resulted in a mortality of 71% within 7 days. During this period animals revealed a decrease in body weight, in arterial pressure, in leukocyte count, in plasma pH and in plasma lactic acid concentrations, and an increase in heart rate and in total plasma protein concentration. In shocked and expiring piglets an increase in haematocrit and a decrease in base excess and actual bicarbonate were observed. Chlorpromazine, administered intramuscularly on 3 successive days following the dual infection in 8 K88ac susceptible pigs, in a dosage of 2 and 1.5 mg/kg.24 h, somewhat retarded the appearance of severe diarrhoea and suppressed vomiting. These beneficial effects, however, did not result in an increased survival.

The effects of eight neuroleptic drugs injected into the cerebral ventricles on behavior, autonomic and motor activity of unanesthetized cats have been studied. Chlorpromazine, trifluorpromazine, droperidol, haloperidol, domperidone and spiperone induced emotional behavior (restlessness, miaowing, rage, attack, defense, fighting with paws, biting), autonomic (mydriasis, tachypnoea, dyspnoea, panting, salivation, defecation, urination, licking, vomiting) and motor (ataxia, muscular weakness, adynamia) phenomena. The main and the most consistent effect was the motor impairment, while the aggression was inconsistent and of moderate intensity. Of the neuroleptic drugs injected, only spiperone, domperidone and trifluorpromazine produced a dose-dependent motor impairment. The autonomic effects were also inconsistent and of low intensity. Metoclopramide induced inconsistent autonomic and motor effects, while sulpiride was devoid of any visible behavioral, autonomic and motor activity. It appears, therefore, that the motor impairment as well as the aggression caused by the neuroleptic drugs is perhaps related to central D-1 rather than to central D-2 dopamine receptors, but an effect on central norepinephrine and on central serotonin receptors cannot be excluded.

Effects of various emetic and antiemetic drugs were studied using Suncus murinus for its potential use as an experimental model in emetic research. Subcutaneous injection of nicotine bitartrate (10-15 mg/kg), veratrine sulfate (0.5-1.0 mg/kg), emetine dihydrochloride (40-80 mg/kg) and oral administration of copper sulfate (20-100 mg/kg) caused dose-dependent emesis in suncus. The ED50 of nicotine, veratrine, emetine and copper sulfate were 7.9, 0.4, 47.6 and 21.4 mg/kg, respectively. However, subcutaneously injected apomorphine hydrochloride (0.1-100 mg/kg), digitoxin (0.5-1.0 mg/kg) and orally administered emetine dihydrochloride (10-80 mg/kg) did not induce the vomiting. Chlorpromazine and promethazine decreased the emetic effect of nicotine, veratrine and copper sulfate, but scopolamine hydrobromide was not effective. These results indicate that the Suncus murinus is sensitive to various emetic and antiemetic drugs and can be used as a new experimental animal model for the emesis. Emetic behavior of suncus was discussed in comparison with other animals.

A randomized, double-blind controlled trial of nabilone versus chlorpromazine was performed in 20 patients with advanced gynaecological cancer who received chemotherapy including cis-platinum. Each patient served as his own control. Nabilone was administered at a dose of 3 mg given orally three times a day, starting the day before cis-platinum and ending the day after. Chlorpromazine was administered at a dose of 12.5 mg given IM, 15 minutes before the start of cis-platinum. Nabilone, in comparison with chlorpromazine did not significantly reduce the number of vomiting. Ten patients preferred nabilone, 5 preferred chlorpromazine and 3 were undecided. Predominant side effects noted by patients were similar for both agents and included somnolence, dry mouth and orthostatic hypotension. No other intervention besides reassurance of the patient was necessary to treat these adverse reactions.

In cytostatic drug treatment, nausea and vomiting are very frequent, unpleasant and undesirable side effects that cause considerable discomfort to the patient. However, many established antiemetics (Torecan, haloperidol, Valium, Largactil etc.) have not shown significant antiemetic activity in the patients to whom cytostatics were applied. In our controlled randomized clinical trial, the antiemetic activity of methylprednisolone was investigated and compared with placebo (10 ml saline) and Torecan. All the compounds were injected before cis-platinum administration, knowing that this agent induces vomiting in almost 100% of patients. Ninety patients entered the study and have been evaluated. The results of the trial have shown that methylprednisolone in the single dose of 250 mg applied i.v. 2 h before injection of a cytostatic agent experienced pronounced antiemetic activity in 48% of the patients (15/31), as compared to Torecan 21% (6/29) and placebo 13% (4/30). This difference was statistically significant (P less than 0.01). No side effects were recorded after methylprednisolone application. The results of the study showed that methylprednisolone possesses a pronounced antiemetic activity in almost half of the patients treated with cis-platinum.

Systemic administration of apomorphine, angiotensin II, neurotensin and leucine-enkephalin induces emesis in dogs in a dose-dependent fashion. Receptors for Leu-enkephalin and angiotensin II but not apomorphine show receptor desensitization, such that a second systemic administration 5 min after the first is ineffective. Domperidone blocked the emetic response to apomorphine but not to Leu-enkephalin or angiotensin II. Naloxone selectively blocked the Leu-enkephalin response, while saralasin blocked responses to both angiotensin II and Leu-enkephalin, but not apomorphine. Chlorpromazine prevented the emetic response to all agents, suggesting a dopamine receptor in the emetic pathway on the brain side of the blood-brain barrier. In dogs with ablation of the area postrema the emetic response to apomorphine and all peptides was prevented.

Levonantradol is a cannabis derivative. Cannabinoid anti-emetics are being assessed in cancer chemotherapy but have been little used in radiotherapy to date. A pilot study and randomised trial compared the anti-emetic effect of a standard drug (Chlorpromazine 26 mg) with Levonantradol at two doses (0.5 and 0.75 mg) in patients receiving palliative single fraction radiotherapy to sites likely to cause nausea and vomiting. Most patients were out-patients. Both drugs were well tolerated. The frequency of vomiting was similar in all three groups in both the pilot study and randomised trial.
