The effectiveness of 50 mg cyclizine and 2.5 mg perphenazine against the emetic sequelae of 100 mg meptazinol were studied in a randomized double-blind placebo-controlled trial. Three groups of 40 women received the opioid, together with an anti-emetic by i.m. injection, as premedication prior to minor gynaecological surgery. Beneficial or noxious effects were noted at standard time intervals and anaesthesia standardized as incremental methohexitone with nitrous oxide/oxygen. In the placebo group, 33 out of 40 subjects experienced either nausea or vomiting at some time after the opioid. Cyclizine, 50 mg, provided significant reduction of emetic tendency in both pre-operative and post-operative phases of the study with 22 out of 40 subjects experiencing nausea or vomiting overall. Perphenazine, 2.5 mg, showed no useful anti-emetic effect. Both anti-emetics increased the soporific effect of premedication at the 90-min interval. Subjects receiving perphenazine experienced significantly more dizziness than those of other groups.

Antiemetic effects of perphenazine and prochlorperazine, both administered by continuous i.v. infusion after a loading dose, were compared in patients receiving cisplatin. Study subjects were 6 men and 13 women for whom other antiemetic therapy had failed; each patient was studied during two courses of cisplatin therapy. Patients were randomly selected to receive either perphenazine or prochlorperazine during the first course; for the second course, each received the other antiemetic. During drug administration, nausea, retching, vomiting, and side effects of the antiemetic were recorded hourly by the patient and concurrently by a pharmacist observer (both blinded). Each patient's scores on nausea, retching, and vomiting were compared by drug and by treatment sequence. Evaluable data for 17 patients showed that aggregate differences between responses to the two drugs were not significant. Fourteen patients had significantly less nausea, retching, and vomiting during the second course of treatment. Few side effects were reported. Nervousness was experienced with prochlorperazine in four patients and perphenazine in one, and drowsiness occurred with prochlorperazine in four patients and perphenazine in three. Perphenazine and prochlorperazine, when given in equal doses and administered by continuous i.v. infusion after a loading dose, were equally effective in controlling nausea and vomiting associated with cisplatin therapy.

In the effort to improve treatment effectiveness in glioblastoma, this short note reviewed collected data on the pathophysiology of glioblastoma with particular reference to intersections with the pharmacology of perphenazine. That study identified five areas of potentially beneficial intersection. Data showed seemingly 5 independent perphenazine attributes of benefit to glioblastoma treatment - i) blocking dopamine receptor 2, ii) reducing centrifugal migration of subventricular zone cells by blocking dopamine receptor 3, iii) blocking serotonin receptor 7, iv) activation of protein phosphatase 2, and v) nausea reduction. Perphenazine is fully compatible with current chemoirradiation protocols and with the commonly used ancillary medicines used in clinical practice during the course of glioblastoma. All these attributes argue for a trial of perphenazine's addition to current standard treatment with temozolomide and irradiation. The subventricular zone seeds the brain with mutated cells that become recurrent glioblastoma after centrifugal migration. The current paper shows how perphenazine might reduce that contribution. Perphenazine is an old, generic, cheap, phenothiazine antipsychotic drug that has been in continuous clinical use worldwide since the 1950's. Clinical experience and research data over these decades have shown perphenazine to be well-tolerated in psychiatric populations, in normals, and in non-psychiatric, medically ill populations for whom perphenazine is used to reduce nausea. For now (Summer, 2020) the nature of glioblastoma requires a polypharmacy approach until/unless a core feature and means to address it can be identified in the future. Conclusions: Perphenazine possesses a remarkable constellation of attributes that recommend its use in GB treatment.
