Clinical Study to Evaluate the Possible Efficacy and Safety of Fexofenadine in Patients With Parkinson's Disease Treated With Conventional Treatment

Short title used by the registry

Fexofenadine as Adjuvant Therapy in Parkinson Disease

Original description

Parkinson's disease (PD) is a chronic, progressive neurological disorder characterized by both motor and non-motor symptoms. PD is the second most common neurodegenerative disorder after Alzheimer's disease and the most common movement disorder. PD has age-related pathology; it is present in 1-2% of the population over 60 years of age. The disease is characterized by a triad of disordered voluntary motor activity in the form of bradykinesia (slowness of movement) or even akinesia (absence of movement),rigidity and postural instability, and a resting tremor of the hands and less commonly the feet.

Conditions reported: Parkinson Disease
