Interactions between your drugs

Moderate

tolazoline alfuzosin

Applies to: tolazoline and alfuzosin

GENERALLY AVOID: Additive pharmacodynamic effects may be expected when alfuzosin is coadministered with other alpha-blockers. Clinical data have not been reported, but there may be an increased risk and/or severity of adverse effects related to blockade of alpha-1 adrenergic receptors in the peripheral vasculature such as postural hypotension, dizziness, headache, syncope, priapism, and nasal congestion. These effects have occurred with alfuzosin even when given alone for the treatment of benign prostatic hyperplasia, despite relative selectivity for the 1A subtype of alpha-1 adrenoreceptors located in prostatic and bladder tissues.

MANAGEMENT: The use of alfuzosin in combination with other alpha-blockers should be avoided.

ADJUST DOSING INTERVAL: Administration of alfuzosin with food enhances oral bioavailability. According to the manufacturer, extent of absorption is 50% higher when administered under fed conditions compared to fasting conditions.

MANAGEMENT: To ensure maximal oral absorption, alfuzosin should be administered with or immediately after a meal.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
