Adrenergic agonist. Sympathomimetic. Phenylpropanolamine nonselectively acts as an agonist for the alpha-adrenergic and beta-adrenergic receptor. These receptors are found throughout the body, such as on sphincters, blood vessels, smooth muscle, and heart. The most profound effects observed with phenylpropanolamine are on vascular smooth muscle (vasoconstriction) and urethral smooth muscle (increased tone of urethra). The half-life in dogs is 4-7 hours. However, the duration of effect may be at least 8-12 hours and as long as 24 hours in some animals. A longer interval of administration may pr
Phenylpropanolamine (PPA) has been used as a decongestant, as a mild bronchodilator, and to increase tone of the urinary sphincter. Pseudoephedrine and ephedrine are related drugs that produce similar alpha-receptor and beta-receptor effects. The most common use in animals is for treating urinary incontinence. The mechanism for this action appears to be via stimulating receptors on the sphincter. It has also been used to treat priapism (persistent erection) in dogs. Abuse potential and adverse effects have limited the routine use as a decongestant and appetite suppressant in human medicine. Mo
