AUTONOMIC NERVOUS SYSTEM AGENT; ALPHA- AND BETA-ADRENERGIC AGONIST; BRONCHODILATOR
Temporary relief of bronchospasm, acute asthmatic attack, mucosal congestion, hypersensitivity and anaphylactic reactions, syncope due to heart block or carotid sinus hypersensitivity, and to restore cardiac rhythm in cardiac arrest. Ophthalmic preparation is used in management of simple (open-angle) glaucoma, generally as an adjunct to topical miotics and oral carbonic anhydrase inhibitors; also used as ophthalmic decongestant. Relaxes myometrium and inhibits uterine contractions; prolongs action and delays systemic absorption of local and intraspinal anesthetics. Used topically to control superficial bleeding.
