TRIHEXYPHENIDYL HYDROCHLORIDE
About
TRIHEXYPHENIDYL HYDROCHLORIDE belongs to a group of medicines called anti-spasmodic agents used as an adjunct to treat Parkinson’s disease and extrapyramidal symptoms (drug-induced movement disorders). Parkinson’s disease is a progressive neurological disorder in which the first signs are problems with movements.
TRIHEXYPHENIDYL HYDROCHLORIDE contains ‘Trihexyphenidyl hydrochloride’, which works by relaxing the muscles and nerve impulses that control muscle functioning. Besides this, TRIHEXYPHENIDYL HYDROCHLORIDE also balances chemical messengers called neurotransmitter in the brain, thereby improves muscle control and reduces stiffness, thus helps the muscles move naturally.
You are advised to take TRIHEXYPHENIDYL HYDROCHLORIDE for as long as your doctor has prescribed it for you, depending on your medical condition. Sometimes, you may experience certain common side effects such as nausea, vomiting, dizziness, constipation, weakness, headache, dry mouth, decreased urination, drowsiness, and feeling nervous or restless. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Do not discontinue TRIHEXYPHENIDYL HYDROCHLORIDE on your own. Consult your doctor before taking TRIHEXYPHENIDYL HYDROCHLORIDE if you are pregnant or breastfeeding.

Medicinal Benefits
TRIHEXYPHENIDYL HYDROCHLORIDE contains Trihexyphenidyl hydrochloride, an anti-spasmodic agent used to treat the symptoms of Parkinson’s disease and extrapyramidal symptoms (drug-induced movement disorders). TRIHEXYPHENIDYL HYDROCHLORIDE exerts a direct inhibitory effect upon the parasympathetic nervous system. It works by relaxing the muscles and nerve impulses that control muscle functioning. TRIHEXYPHENIDYL HYDROCHLORIDE improves muscle control and reduces stiffness, thereby helps the muscles move naturally. TRIHEXYPHENIDYL HYDROCHLORIDE is used as an adjuvant therapy along with levodopa to treat Parkinson's disease. Additionally, TRIHEXYPHENIDYL HYDROCHLORIDE is used to control drug-induced movement disorders caused by CNS drugs such as dibenzoxazepines, thioxanthenes, phenothiazines, and butyrophenones.

Patients Concern
Disease/Condition Glossary
Parkinson’s disease: It is a progressive neurological disorder in which the first signs are problems with movements. Dopamine is a naturally-occurring neurotransmitter in the brain which is reduced or absent in people with Parkinson’s disease. Due to this, problems arise with smooth and coordinated movements. Symptoms include decreased ability to smell, stooped posture, changes in voice, constipation, small/ cramped handwriting, tremor, slow movements, stiffness of arms, legs, trunk, and balance problems.
