Orciprenaline (also known as metaproterenol), a synthetic amine, is structurally and pharmacologically similar to isoproterenol. Orciprenaline is used exclusively as a bronchodilator. The pharmacological effects of beta adrenergic agonist drugs, such as orciprenaline, are at least in part attributable to stimulation through beta adrenergic receptors of intracellular adenyl cyclase, the enzyme which catalyzes the conversion of adenosine triphosphate (ATP) to cyclic- 3',5'- adenosine monophosphate (c-AMP). Increased cAMP levels lead to relaxation of bronchial smooth muscles and inhibition of the release of inalammatory mediators from mast cells that are involved in promoting immediate hypersensitivity .
- Mechanism of action
Orciprenaline stimulates the β2-adrenergic receptor expressed in the lungs, uterus, and vasculature supplying skeletal muscles by acting as a moderately selective agonist. It exerts minimal or no effect on alpha-adrenergic receptors. Intracellularly, the actions of orciprenaline are mediated by cAMP, the production of which is augmented by beta stimulation. The drug is believed to work by activating adenylate cyclase, the enzyme responsible for producing the cellular mediator cAMP.

- Protein binding
Hepatic and gastric. The major metabolite, orciprenaline-3-0-sulfate, is produced in the gastrointestinal tract. Orciprenaline is not metabolized by catechol-0-methyltransferase nor have glucuronide conjugates been isolated to date.
