The role of beta blockers

Beta-adrenergic receptor antagonists, or beta blockers, are a class of drugs that interfere with the transmission of sympathetic nerve impulses by binding to beta-adrenergic receptors. By inhibiting sympathetic stimulation of a target organ, beta blockers compete with neurotransmitters for beta-1 or beta-2 adrenergic receptor sites.
