Procyclidine is used to treat a range of conditions related to movement disorders, particularly those caused by chemical imbalances in the brain. It is often used to control symptoms of Parkinson's disease, such as muscle stiffness, tremors, and difficulty moving; to reduce the side effects of certain antipsychotic medications, such as rigidity or involuntary muscle contractions; and to help calm muscle spasms or other movement disorders associated with the nervous system.
Procyclidine should be used under close medical supervision to avoid any potential side effects or unwanted interactions with other medications.
