MedKoo CAT#: 412303

CAS#: 65132-60-7 (HCl)

Description: Carbidopa hydrochloride is a drug given to people with Parkinson's disease in order to inhibit peripheral metabolism of levodopa. This property is significant in that it allows a greater proportion of peripheral levodopa to cross the blood–brain barrier for central nervous system effect.
