chlormethiazole + haloperidol

Chlormethiazole + haloperidol is a combination therapy consisting of two distinct drugs used together, primarily in the management of delirium tremens and severe alcohol withdrawal. Chlormethiazole is a sedative and hypnotic agent that acts as a central nervous system depressant, mainly by potentiating GABAergic neurotransmission, leading to its calming effects. Haloperidol is a typical (first-generation) antipsychotic that exerts its primary effect through antagonism of dopamine D2 receptors in the brain, reducing psychotic symptoms such as hallucinations and agitation. The rationale for combining these agents is to address both the neurovegetative (autonomic) disturbances with chlormethiazole and the psychotic features with haloperidol during acute alcohol withdrawal syndromes like delirium tremens.
