PHYSIOLOGY Transmembrane receptors composed of excitable G-proteins‚ which cross the cell membrane and link selectively with extra cellular ligands are called adrenoceptors. They are also termed as α-2 Adrenoceptor agonists α-2 adrenergic receptors. Three α-2 isoreceptors - α-2a‚ α-2b and α-2c of adreno receptor bind α-2 agonists and antagonists with similar rapport and share an amino acid composition homology of roughly 70 to 75%. The efficacy of sub receptor specific agonists that constrains deleterious

Metoprolol Metoprolol is a beta-Adrenergic blocking agent. Beta receptors are part of the sympathetic nervous system and are found on cells of the heart‚ smooth muscles‚ in airways‚ arteries and kidneys. Associated with stress response‚ they are stimulated by epinephrine. Beta blockers interfere with the binding of epinephrine at the receptors. Metoprolol works by inhibiting the response to adrenergic stimuli by blocking beta one adrenergic receptors within the myocardium. (Hoffman‚ Jones
