Rotigotine API produced by major manufacturers like Uquifa and Neuland Laboratories plays a key role in Parkinson's disease drugs through its specific neuropharmacological profile.

Dopamine Depletion in Parkinson's

Loss of dopamine-producing neurons in the substantia nigra pars compacta leads to striatal dopamine deficiency, manifesting as motor impairment.

Rotigotine is a Dopamine Agonist

Rotigotine acts as a non-selective dopamine receptor agonist, mimicking dopamine's actions by binding to D1-D5 subtypes in nigrostriatal and mesocortical pathways.

Activation of Downstream Signaling

This stimulates G-protein coupled, second messenger cascades that increase neuronal excitability and elevate motor function-regulating neurotransmitters like glutamate.

Resulting Therapeutic Effects

The net result is enhanced dopaminergic neurotransmission, compensating for the underlying loss of endogenous dopamine. Common Parkinson's motor symptoms improve as shown below:

Therefore, high-quality rotigotine API forms the pharmacological basis for an important non-levodopa treatment approach in Parkinson's disease.
