Triperiden is primarily used in the treatment of Parkinson's disease and other conditions characterized by involuntary muscle movements, such as drug-induced extrapyramidal symptoms. It functions as an anticholinergic agent, helping to restore the balance of neurotransmitters in the brain, which alleviates symptoms like tremors, rigidity, and bradykinesia. Additionally, it is effective in managing dystonia and akathisia, often caused by antipsychotic medications. Its ability to block acetylcholine receptors makes it a valuable therapeutic option for controlling motor disturbances and improving patient quality of life.
