Interactions between your drugs

Moderate

pentoxifylline silodosin

Applies to: pentoxifylline and silodosin

MONITOR: Pentoxifylline may potentiate the action of hypotensive agents. Small decreases in blood pressure have been observed in some patients treated with pentoxifylline plus nifedipine or captopril. The mechanism of interaction has not been described.

MANAGEMENT: Caution is advised if pentoxifylline is used in combination with hypotensive agents. Periodic systemic blood pressure monitoring is recommended.

Drug and food interactions

Moderate

silodosin food

Applies to: silodosin

ADJUST DOSING INTERVAL: Food may reduce the oral bioavailability of silodosin. The effect of a moderate-fat, moderate-calorie meal on silodosin pharmacokinetics was variable and decreased silodosin maximum plasma concentration (Cmax) by approximately 18% to 43% and systemic exposure (AUC) by 4% to 49% across three different studies. The maximum effect of food (i.e., coadministration with a high-fat, high-calorie meal) on the pharmacokinetics of silodosin was not evaluated. Safety and efficacy clinical trials for silodosin were always conducted in the presence of food intake.

MANAGEMENT: Patients should be instructed to take silodosin with a meal to reduce the risk of adverse events.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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.
