Diuretic and vasodilator drugs alter the BP response to saralasin causing drug interactions. Saralasin-induced BP reduction is related directly to PRA and intravascular volume. Diuretic agents deplete intravascular volume and elevate PRA, enhancing saralasin hypotension. Vasodilating agents increase PRA and may induce angiotensin dependence of BP. Thus, with potent vasodilators, saralasin can induce hypotension. Rebound hypertension has been reported after saralasin infusion in several patients with accelerated or malignant hypertension. Theoretically, this BP elevation could be related to sustained release of renin resulting from disinhibition of an intrarenal angiotensin receptor inhibitory to renin release. Since propranolol can block saralasin-induced renin release, angiotensin and beta-blockers could constitute a beneficial drug interaction.
