Trihexyphenidyl

Trihexyphenidyl Hydrochloride (Benzhexol) is a synthetic tertiary amine centrally acting anticholinergic (antimuscarinic) agent on the WHO Model List of Essential Medicines. It competitively antagonizes muscarinic acetylcholine receptors (M1) in the corpus striatum, restoring balance between dopamine deficiency and cholinergic excess. Indicated for adjunctive treatment of Parkinson's disease (particularly for reducing resting tremor and rigidity) and prevention/treatment of drug-induced extrapyramidal symptoms (acute dystonia, akathisia, parkinsonism) caused by neuroleptics.

Risperidone and Trihexyphenidyl (Benzhexol) is a therapeutic combination designed to provide antipsychotic efficacy while preventing drug-induced movement disorders. Risperidone, a benzisoxazole atypical antipsychotic, blocks dopamine D2 and serotonin 5-HT2A receptors to control psychosis, while trihexyphenidyl, a centrally acting anticholinergic agent, blocks muscarinic M1 receptors to restore the dopamine-acetylcholine balance in the basal ganglia, preventing extrapyramidal symptoms (acute dystonia, parkinsonian rigidity, tremors, akathisia). Indicated for schizophrenia, schizoaffective disorder, and severe psychotic agitation complicated by high extrapyramidal risk.

Trifluoperazine is a high-potency piperazine phenothiazine typical antipsychotic. It potently blocks postsynaptic dopamine D2 receptors in the mesolimbic and nigrostriatal systems, producing robust anti-hallucinatory and anti-delusional effects with low sedation and low autonomic burden, but high propensity for extrapyramidal movement disorders. Indicated for schizophrenia, other psychotic disorders, and short-term non-psychotic anxiety.
