buprenorphine triptorelin

Applies to: buprenorphine and Triptodur (triptorelin)

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

Major

buprenorphine food

Applies to: buprenorphine

GENERALLY AVOID: Concomitant use of buprenorphine with benzodiazepines or other central nervous system (CNS) depressants (e.g., nonbenzodiazepine sedatives/hypnotics, anxiolytics, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol) may increase the risk of buprenorphine overdose, severe respiratory depression, coma, and death. Reported cases have primarily occurred in the setting of buprenorphine maintenance treatment for opiate addiction, and many, but not all, involved abuse or misuse of buprenorphine including intravenous self-injection. The mechanism of interaction probably involves some degree of additive pharmacologic effects. Preclinical studies also suggest that benzodiazepines can alter the usual ceiling effect on buprenorphine-induced respiratory depression and render the respiratory effects of buprenorphine appear similar to those of full opioid agonists. Coadministration of buprenorphine with some CNS depressants such as alcohol, benzodiazepines, and phenothiazines may also increase the risk of hypotension.

MANAGEMENT: The use of opioids in conjunction with benzodiazepines or other CNS depressants should generally be avoided unless alternative treatment options are inadequate. If coadministration is necessary, the dosage and duration of each drug should be limited to the minimum required to achieve desired clinical effect. Patients should be monitored closely for signs and symptoms of respiratory depression and sedation, and advised to avoid driving or operating hazardous machinery until they know how these medications affect them. Extreme caution is advised when prescribing buprenorphine to patients who are addicted to opioids and also abusing benzodiazepines or alcohol. Due to potential risk of overdose and death, dependence on sedative-hypnotics such as benzodiazepines or alcohol is considered a relative contraindication for office-based buprenorphine treatment of opioid addiction. For patients who have been receiving extended therapy with both an opioid and a benzodiazepine and require discontinuation of either medication, a gradual tapering of dose is advised, since abrupt withdrawal may lead to withdrawal symptoms. Severe cases of benzodiazepine withdrawal, primarily in patients who have received excessive doses over a prolonged period, may result in numbness and tingling of extremities, hypersensitivity to light and noise, hallucinations, and epileptic seizures.

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.
