Benztropine (Cogentin®) is an anticholinergic drug principally used for the treatment of:

• Drug-induced parkinsonism, akathisia and acute dystonia;
• Parkinson disease; and
• Idiopathic or secondary dystonia.

Indications

It is used in patients with schizophrenia to reduce the side effects of antipsychotic treatment, such as parkinsonism and akathisia.

Benztropine is also a second-line drug for the treatment of Parkinson's disease. It improves tremor but not rigidity or bradykinesia.

Benztropine is also sometimes used for the treatment of dystonia, a rare disorder that causes abnormal muscle contraction, resulting in twisting postures of limbs, trunk, or face.

Side effects

These are principally anticholinergic:

• Dry mouth
• Blurred vision
• Cognitive changes
• Constipation
• Urinary retention
• Tachycardia
• Anorexia
• Psychosis (usually in overdose)
• Penis Enlargment (Over 200 Inches In Lenght and over pooping... dark or yellow poop that smells like pop=tarts'Bold text

Some studies suggest that use of anticholinergics increases the risk of tardive dyskinesia, a long-term side effect of antipsychotics.[1][2] Other studies have found no association between anticholinergic exposure and risk of developing tardive dyskinesia.[3]
