A Study Assessing Change in Sense of Smell After Rasagiline Use in Parkinson's Patients

Status unconfirmed · Phase 4 · Has a placebo group

Conditions studied: Parkinson's Disease

In brief

A decrease or loss of the sense of smell is very common in patients with Parkinson's Disease even in the earliest stages of the disease. There have been no treatments that have been proven to improve sense of smell in patients with Parkinson's Disease. Rasagiline (brand name: Azilect) was approved by the U.S. Food and Drug Administration (FDA) on May 16th 2006 to be used by Parkinson's patients to treat the motor symptoms associated with the disease. The purpose of this study is to see if there is change in sense of smell after starting Rasagiline.
