Interactions between your drugs

Moderate

leuprolide paliperidone

Applies to: Fensolvi (leuprolide) and paliperidone

GENERALLY AVOID: Long-term androgen deprivation therapy (ADT) can prolong the QT interval. Coadministration of ADT with other agents that may prolong the QT interval could also result in additive effects and an increased risk of ventricular arrhythmias including torsade de pointes and sudden death. The risk may be increased in patients with certain underlying risk factors like congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia). Studies in young men have shown that endogenous serum testosterone levels are inversely associated with QTc (QT interval corrected for heart rate) duration. Clinical trials in men with low serum testosterone levels have reported testosterone administration being associated with a shortening of QTc. Likewise, studies using ADT have shown that it may prolong the QT interval; however, this effect may vary by drug, dose, or even each drug class that can be used to reduce testosterone levels. A clinical study comparing abarelix to a luteinizing hormone-releasing hormone agonist plus nonsteroidal antiandrogen therapy found that both therapies prolonged the mean Fridericia-corrected QT interval (QTcF) by more than 10 msec from baseline. Approximately 20% of patients in both groups had either changes from baseline QTc of >30 msec or end-of-treatment QTc values >450 msec. Similarly, a study comparing degarelix to leuprolide found that approximately 20% of patients on each drug had QT/QTc intervals >450 msec after 1 year of treatment. From baseline to end of study, the median change in QTcF was 12.3 msec for degarelix and 16.7 msec for leuprolide. Some drugs used to lower testosterone levels may also have other side effects that can predispose a patient to QT prolongation and torsade de pointes. For example, inhibitors of 17 alpha-hydroxylase/C17,20-lyase (CYP17) like abiraterone may cause hypokalemia as a result of increased mineralocorticoid levels. Clinical data on ADT prolonging the QT interval in women and children are lacking.

MANAGEMENT: The benefits of androgen deprivation therapy (ADT) should be carefully assessed against the potential risk in patients receiving other drugs known to prolong the QT interval. Electrolyte abnormalities should be corrected prior to initiating therapy, and monitoring of electrocardiograms and electrolytes may be advisable. The manufacturer's labeling as well as current clinical guidelines should be consulted for monitoring recommendations.

Drug and food interactions

Moderate

paliperidone food

Applies to: paliperidone

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of paliperidone. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

Administration with food may increase the bioavailability of paliperidone from the extended release tablets. In healthy ambulatory subjects, administration of a 12 mg paliperidone extended release tablet with a standard high-fat/high-caloric meal resulted in 60% and 54% increases, respectively, in the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of paliperidone compared to administration under fasting conditions. The clinical significance of these changes is unknown.

MANAGEMENT: Patients receiving paliperidone should be advised to avoid the consumption of alcohol. Since clinical trials establishing the safety and efficacy of paliperidone were carried out without regard to the timing of meals, presumably paliperidone may be administered with or without food.

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.
