Bioactivity | Talinolol (Cordanum) is a long-acting, cardioselective β1-adrenergic receptor blocker. Talinolol exhibits cardioprotective and antihypertensive activities. Talinolol is also a well-known and frequently used probe substrate for P-glycoprotein (P-gp) activity[1][2]. |
Invitro | Human OATP1A2-, rat Oatp1a5-, and rat Mdr1a-mediated Talinolol transport can be inhibited by naringin, with IC50s of 343, 12.7, and 604 μM, respectively, in LLC-PK1 cell and Xenopus laevis oocyte systems[3]. |
In Vivo | Talinolol (20 mg/kg; i.p.) plasma and liver AUC0-5 h are increased by Zosuquidar administration[2].Bioavailability of Talinolol can be enhanced by coadministration with grapefruit juice (GFJ) in rats[3]. |
