What is Cogentin

BenzatropineThe Generic name of this drug
Treatment SummaryBenztropine is a medication used to treat the symptoms of Parkinson’s disease. It is made up of two components - a tropane ring similar to cocaine, and a diphenyl ether from dialkylpiperazines. Benztropine was developed by USL Pharma and approved by the FDA in 1996. It works by blocking dopamine receptors in the brain, which helps to reduce the symptoms of Parkinson’s disease.

How Cogentin Affects PatientsBenztropine works by blocking the reuptake of dopamine in the nerve cells. This results in an increased amount of dopamine in the body. The effects of benztropine can be felt after 1-2 hours when taken orally and a few minutes when taken through an injection. The effects can last up to 24 hours. Benztropine also has a sedative effect, as well as antihistamine and anticholinergic properties that are similar to the effects found with pyrilamine and atropine.
How Cogentin works in the bodyBenztropine has two main effects on the body. First, it blocks dopamine transporters in the brain, which helps to balance out dopamine levels. It also binds to muscarinic receptors in the striatum, blocking their activity. This reduces the activity of acetylcholine in the body, which is useful for Parkinson's patients.

Cogentin Reviews: What are patients saying about Cogentin?

5Patient Review
Cogentin for Extrapyramidal Reaction
I've had bipolar disorder since I was a kid, and Cogentin has been really effective for me.
5Patient Review
Cogentin for Parkinson Symptoms
I've been using Cogentin for about 10 days now, and I'm already feeling a lot better. I'm more confident to take on tasks that I would have avoided before, and my tremor is gradually getting better.
4Patient Review
Cogentin for Parkinsonism due to Degenerations in the Brain
I started taking cogentin to help with side effects of my antidepressants, and it really made a difference. I felt more normal and had more energy. Additionally, it helped with some cognitive problems I was experiencing after a brain injury.
4Patient Review
Cogentin for Extrapyramidal Reaction
This medicine is great for reducing the rigidity and tremors that come with EPS and Dystonia, two conditions I've dealt with for most of my life. The only downside is that it gives me a really dry mouth shortly after taking it.
3Patient Review
Cogentin for Extrapyramidal Reaction
I took cogentin a few years ago to counteract side effects from a neuroleptic (EPS). Soon I was falling asleep all the time while driving, unable to speak in a complete sentence, and apparently raving about nonexistent missiles in Japan. I can't even remember most of what happened during that period of time. When I saw my doctor and couldn't communicate with him at all either by speaking or writing, he had to hospitalize me to get me stabilized and to change my medications.
1.3Patient Review
Cogentin for Parkinson Symptoms
My mother started taking this to counter side effects of Abilify. However, she only lasted three days because the medication caused such severe memory loss and dry mouth that it interfered with her quality of life. Not worth it!
