Description
(extracted from source data)
PHARMACODYNAMICS Prochlorperazine is an antipsychotic agent that works to promote postsynaptic inhibition of dopaminergic neurons.[L6640] It also exerts its anti-emetic actions via anti-dopaminergic effects, where it displays similar efficacy as ondansteron, a 5HT-3 receptor antagonist and anti-emetic, in preventing delayed nausea and vomiting.[A179179] Prochlorperazine was shown to inhibit histaminergic, cholinergic and alpha-1 adrenergic receptors.[A179173,L6637] The blockade of alpha-1 adrenergic receptors may result in sedation, muscle relaxation, and hypotension. It displays anti-anxiety effects as well.[L6640] Compared to other phenothiazine derivatives, prochlorperazine is less sedating and has a weak propensity for causing hypotension or potentiating the effects of CNS depressants and anesthetics.[L6646] Other than its primary action on D2 receptors, one study showed that prochlorperazine may inhibit the P2X7 receptor in human macrophages, leading to inhibition of calcium ion influx.[L6637]
MOA The mechanism of action of prochlorperazine has not been fully determined, but may be primarily related to its anti-dopaminergic effects. Prochlorperazine blocks the D2 dopamine receptors in the brain, which are somatodendritic autoreceptors. Inhibition of D2 receptor signaling results in the blockade of postsynaptic dopamine receptors in the mesolimbic system [L6643] and an increased dopamine turnover. Nausea and vomiting are proposed to arise from peripheral or central stimulation of serotonin type 3 (5-HT3) and dopamine type 2 receptors, the predominant receptors expressed at the chemoreceptor trigger zone (CTZ).[A179194,L6643] Prochlorperazine exerts antiemetic effects and was shown to inhibit apomorphine-induced vomiting by blocking D2 dopamine receptors in the CTZ.[A179179].
INDICATION Indicated for the symptomatic treatment of severe nausea and vomiting.[label]; ; Indicated for the management of manifestations of psychotic disorders, such as schizophrenia and generalized non-psychotic anxiety. The use of prochlorperazine for the management of generalized non-psychotic anxiety is typically not a first-line therapy and should be limited to doses of less than 20 mg per day or for shorter than 12 weeks.[label,L6634]; ; Off-label uses include use in emergency settings for adult and pediatric migraines. The American Headache Society recommends the use of prochlorperazine as the first-line medication in this setting. In pediatric migraines, a non-steroidal anti-inflammatory agent is often used in combination with dopamine antagonist.[L6637]
ROE Prochlorperazine is reported to be mainly excreted via the feces and bile.[L6646] Low quantities of unchanged prochlorperazine and its metabolite were detectable in the urine.[A179173]
METABOLISM Prochlorperazine undergoes hepatic metabolism involving oxidation, hydroxylation, demethylation, sulfoxide formation and conjugation with glucuronic acid.[L6649] The oxidation reaction is mediated by CYP2D6.[A179179] N-desmethyl prochlorperazine was detected in the plasma[A179173], as well as prochlorperazine sulfoxide, prochlorperazine 7-hydroxide and prochlorperazine sulfoxide 4'-N-oxide, following oral and buccal administration.[A179188] Prochlorperazine may enter the enterohepatic circulation.[L6646]
ABSORPTION Following oral administration, prochlorperazine is reported to be well absorbed from the gastrointestinal tract. The onset of pharmacological action is about 30 to 40 minutes following oral administration and 10 to 20 minutes following intramuscular administration. The duration of action for all routes is about 3 to 4 hours.[L6646] Following oral administration in healthy volunteers, the mean oral bioavailability was about 12.5%. In these patients, the time to reach the peak plasma concentrations was about 5 hours. Repeated oral dosing resulted in an accumulation of prochlorperazine and its metabolite. Following multiple twice daily dosing, the steady state of prochlorperazine was reached by 7 days.[A179173]
HALF-LIFE Following intravenous and single oral dose administration, the terminal elimination half live were 9 and 8 hours, respectively.[A179173]
