Interactions between your drugs

Moderate

tamsulosin vericiguat

Applies to: Jalyn (dutasteride / tamsulosin) and vericiguat

MONITOR: Vericiguat may cause hypotension and coadministration with antihypertensives, organic nitrates, or agents with hypotensive properties may increase the potential for symptomatic hypotension, especially in patients with hypovolemia, severe left ventricular outflow obstruction, resting hypotension, autonomic dysfunction, or patients with a history of hypotension. Patients with heart failure receiving hemodynamically active substances have reported systolic blood pressure (SBP) reductions of approximately 1 to 2 mmHg with concomitant use. Co-administration of multiple doses of vericiguat up to 10 mg once daily did not significantly alter the seated blood pressure effects of short- and long-acting nitrates in patients with coronary artery disease and concomitant use of short-acting nitrates was well tolerated in patients with heart failure. However, there is limited experience with concomitant use of vericiguat and long-acting nitrates in patients with heart failure and no data on initiation of vericiguat in patients with systolic blood pressure (SBP) less than 100 mmHg or symptomatic hypotension at treatment initiation.

MANAGEMENT: If patients experience tolerability issues (symptomatic hypotension or SBP less than 90 mmHg), temporary down-titration or discontinuation of vericiguat is recommended.

Drug and food interactions

Moderate

tamsulosin food

Applies to: Jalyn (dutasteride / tamsulosin)

ADJUST DOSING INTERVAL: Food may delay the gastrointestinal absorption of tamsulosin. The time to maximum plasma concentration (Tmax) is reached by 4 to 5 hours under fasted conditions and by 6 to 7 hours when tamsulosin is administered with food. The delay in Tmax has the desirable effect of smoothing the tamsulosin plasma concentration profile, thereby reducing fluctuation of the plasma peak and trough concentrations with multiple dosing. Food may also affect the extent of absorption of tamsulosin. It has been reported that taking tamsulosin under fasted conditions results in a 30% increase in bioavailability (AUC) and 40% to 70% increase in peak plasma concentration (Cmax) compared to fed conditions. The effects of food on the pharmacokinetics of tamsulosin are consistent regardless of whether tamsulosin is taken with a light meal or a high-fat meal.

MANAGEMENT: To ensure uniformity of absorption, tamsulosin should be administered approximately one-half hour following the same meal each day.

Moderate

vericiguat food

Applies to: vericiguat

ADJUST DOSING INTERVAL: Administration of vericiguat with food reduces its pharmacokinetic variability and increases its exposure. Vericiguat is less soluble at neutral pH than at acidic pH. Administration of vericiguat with a high-fat, high-calorie meal or low-fat, high-carbohydrate meal increased time to reach peak plasma concentration (Tmax) from about 1 hour (fasted) to about 4 hours (fed) and increased vericiguat systemic exposure (AUC) by 19% and peak plasma concentration (Cmax) by 9% for the 5 mg tablet and by 44% (AUC) and 41% (Cmax) for the 10 mg tablet as compared with the fasted state. Concurrent treatment with drugs that increase gastric pH, such as proton pump inhibitors or antacids, decrease vericiguat AUC by about 30%. Co-treatment with drugs that increase gastric pH did not affect vericiguat exposure in patients with heart failure when vericiguat was taken as directed with food.

MANAGEMENT: Administer vericiguat with food to ensure maximal exposure and decrease pharmacokinetic variability.

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.
