Benztropine (Cogentin), Serum
Use
Benztropine is primarily used in the management of symptoms associated with Parkinson's disease and neuropathic disorders. It acts by balancing neurotransmitters in the brain, specifically by targeting the cholinergic and dopaminergic pathways. Measuring the serum concentration of Benztropine aids in therapeutic drug monitoring to ensure effectiveness and to prevent toxicity.
