Biased Agonism: The Future (and Present) of Inotropic Support.

Biased agonism, which is the concept that different ligands activate different downstream signalling partners in different ratios to cause different functional effects, is yet to gain appropriate appreciation in the field of inotropic pharmacology. Biased agonism has already proven to be a clinically translatable technology in analgesic pharmacology, but this development is yet to be translated into inotropes. A better appreciation of bias in clinically used inotropes and a focus on bias when developing novel inotropes has the potential to lead to more targeted, personalized, and cleaner inotropes.
