ELDEPRYL, with the generic name Selegiline, is a prescription medication primarily used in the treatment of Parkinson's disease. It belongs to a class of drugs known as monoamine oxidase inhibitors (MAOIs). By inhibiting the enzyme monoamine oxidase, Selegiline helps increase the levels of certain neurotransmitters in the brain, such as dopamine, which can improve motor function and alleviate symptoms associated with Parkinson's disease.
