Macrilen and Xenleta

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer information for this interaction is not currently available.GENERALLY AVOID: Macimorelin can cause prolongation of the QT interval. Theoretically, coadministration with other agents that can prolong the QT interval may result in additive effects and increased risk of ventricular arrhythmias including torsade de pointes and sudden death. In a dedicated thorough QT study consisting of 60 healthy subjects, a mean baseline- and placebo-adjusted change in QTcF of 9.6 msec was observed 4 hours following administration of a supratherapeutic dose of macimorelin 2 mg/kg (4 times the recommended dose), which occurred after the mean maximum macimorelin plasma concentration (0.5 hour). A similar increase in the QTcF interval was also observed in a single-ascending dose study, which included three dose levels: 0.5 mg/kg; 1 mg/kg (2 times the recommended dose); and 2 mg/kg (4 times the recommended dose). All three doses levels produced a similar magnitude of QTcF prolongation as reported in the thorough QT study, suggesting an absence of dose-dependent changes. The mechanism for the observed QTcF prolongation is unknown. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia). In addition, the extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s). MANAGEMENT: Coadministration of macimorelin with other drugs that can prolong the QT interval should generally be avoided. A sufficient washout period following discontinuation of these drugs is recommended prior to macimorelin administration. Patients treated with any medication that can cause QT prolongation should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.
