Question

drugs that affect multiple adrenergic receptors are?

Answer 1

The two types of adrenergic receptors are norepinephrine and epinephrine are called alpha receptors and beta receptors .Such receptors are visceral effectors innervated by most sympathetic post ganglionic axons.Both aipha and beta receptors are classified into sub types.The receptors are distinguished by the specific responses they elicit and by their selective binding of drugs that activiate or block them.In general alpha receptors are excitatory .While some beta receptors are excitatory while others are inhibitory.In general norepinephrine stimulates alpha receptors more vigorously than beta receptors wheras epinephrine is a potent stimulator of both alpha and beta receptors.
