Conditions

Parkinson Disease

Brief summary

The clinical manifestations of Parkinson's disease (PD), a chronic neurodegenerative condition, include resting tremor, hypokinesia, bradykinesia, stiffness and postural instability. These motor symptoms are caused by a selective loss and degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNpc) region, which leads to a dopamine (DA) insufficiency in the striatum

Interventions

Carbidopa/levodopa, also known as levocarb and co-careldopa, is the combination of the two medications carbidopa and levodopa. It is primarily used to manage the symptoms of Parkinson's disease

DRUGMetformin

Metformin, sold under the brand name Glucophage, among others, is the main first-line medication for the treatment of type 2 diabetes, particularly in people who are overweight.
