adrenergic beta receptor antagonist drug pathway +
The pharmacokinetics and pharmacodynamics pathway of adrenergic beta receptors blockers. Adrenergic beta receptors, in response to epinephrine or norepinephrine couple to the Gs alpha subunit of heterotrimeric G protein to elicit several responses. Beta receptor antagonists are used to inhibit these responses and they are either selective or non-selective. Genetic variations can result in changes in drug availability and can cause differences in the response of the organism to the drug.
