Description: Lemildipine, also known as NB-818; NPK-1886, is a calcium channel blocker potentially for the treatment of hypertension.. Lemildipine attenuates the TGF response in SHR by dilating afferent arterioles and thereby corrects the left and downward shift of the TGF curve in SHR. In addition, the fall in FF indicates lemildipine-induced efferent arteriolar vasodilatation. Through balanced systemic and glomerular vasodilatation, lemildipine maintains the levels of Pgc and GFR in the face of reduced renal perfusion pressure.
