(±)-Talinolol is primarily used in pharmacological research as a model compound to study the absorption, distribution, metabolism, and excretion (ADME) of drugs, particularly beta-blockers. Its application extends to investigating the role of P-glycoprotein (P-gp) in drug transport across biological membranes, which is crucial for understanding multidrug resistance in cancer therapy. Additionally, (±)-Talinolol serves as a tool in assessing the impact of genetic polymorphisms on drug pharmacokinetics, aiding in personalized medicine approaches. It is also employed in studies exploring drug-drug interactions, especially those involving P-gp inhibitors or inducers, to optimize therapeutic efficacy and minimize adverse effects.
