Compliance for Clinical Use

Mechanism and Biochemical Profile

Nicergoline selectively binds to and antagonizes alpha-1A adrenergic receptors, thereby inhibiting receptor-mediated intracellular signaling cascades and modulating vascular and neuronal smooth muscle tone. This pharmacological attenuation enhances local microcirculation and muscular responsiveness, providing a mechanistic basis for its clinical investigation in treating dysphagia.
