COMPRO vs MEZOFY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prochlorperazine is a phenothiazine antipsychotic that primarily acts as a dopamine D2 receptor antagonist, with additional antagonism at D3, 5-HT2A, alpha1-adrenergic, and histamine H1 receptors. It also has antiemetic effects via D2 blockade in the chemoreceptor trigger zone.
MEZOFY is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane.
5 to 10 mg intramuscularly every 3 to 4 hours as needed; or 5 to 10 mg intravenously at a rate not exceeding 5 mg per minute; or 10 mg orally every 6 to 8 hours; maximum daily dose 40 mg.
MEZOFY (mexiletine) 200 mg orally every 8 hours; may increase to 300 mg every 8 hours if needed.
