DRUG INTERACTION Chlorpromazine is known to interact with other drugs like alcohol, belladona, benzhexol (HCl), benztropine (Mesylate), bethanidine (Sulphate), bovine Insulin, cimetidine (HCl), clonidine (HCl), cyclophosphamide, debrisoquine (Sulphate), dexamphetamine (Sulphate), diazoxide, disulfiram, epirubicin, fosphenytoin, glibornuride, gliquidone, guanethidine, human insulin, imipramine (HCl), insulin lispro, lithium, metacycline (HCl). Always consult your physician for the change of dose regimen or an alternative drug of choice that may strictly be required. MECHANISM OF ACTION Chlorpromazine acts as an antagonist (blocking agent) on different postsysnaptic receptors -on dopaminergic-receptors (subtypes D1, D2, D3 and D4 - different antipsychotic properties on productive and unproductive symptoms), on serotonergic-receptors (5-HT1 and 5-HT2, with anxiolytic, antidepressive and antiaggressive properties as well as an attenuation of extrapypramidal side-effects, but also leading to weight gain, fall in blood pressure, sedation and ejaculation difficulties), on histaminergic-receptors (H1-receptors, sedation, antiemesis, vertigo, fall in blood pressure and weight gain), alpha1/alpha2-receptors (antisympathomimetic properties, lowering of blood pressure, reflex tachycardia, vertigo, sedation, hypersalivation and incontinence as well as sexual dysfunction, but may also attenuate pseudoparkinsonism - controversial) and finally on muscarinic (cholinergic) M1/M2-receptors (causing anticholinergic symptoms like dry mouth, blurred vision, obstipation, difficulty/inability to urinate, sinus tachycardia, ECG-changes and loss of memory, but the anticholinergic action may attenuate extrapyramidal side-effects).
