In the context of Parkinson’s Disease (PD) is a neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta, leading to hallmark motor symptoms such as bradykinesia, tremor, rigidity, and postural instability. Non-motor symptoms are also significant, often preceding motor signs and increasing in complexity as PD advances. Pharmacists play a pivotal role in PD management, optimizing pharmacotherapy, educating patients, and monitoring outcomes. Pharmacologic treatment is symptomatic, with levodopa being the cornerstone, supplemented by dopamine agonists, MAO-B inhibitors, and other agents as the disease progresses. Non-pharmacological interventions such as physical, occupational, and speech therapies are integral for maintaining quality of life. New research into the genetic underpinnings of PD holds promise for future targeted therapies, but currently, a cure remains out of reach. Clinicians must be adept at diagnosing PD, differentiating it from other parkinsonian syndromes, and managing the complex interplay of motor and non-motor symptoms with a personalized approach to care.
