Lorlatinib and Ramelteon Tablets
Determining the interaction of Lorlatinib and Ramelteon Tablets and the possibility of their joint administration.
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:Lorlatinib may reduce the blood levels of ramelteon in some patients, which may make the medication less effective in the treatment of insomnia. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:MONITOR: Coadministration with inducers of CYP450 isoenzymes may decrease the plasma concentrations and pharmacologic effects of ramelteon, which is metabolized by CYP450 1A2 and, to a lesser extent, by CYP450 3A4 and the 2C subfamily of isoenzymes. When a single 32 mg oral dose of ramelteon was administered to healthy volunteers following pretreatment with the potent CYP450 inducer rifampin (600 mg orally once daily for 11 days), total systemic exposure (AUC) to ramelteon and its pharmacologically active metabolite was decreased by an average of approximately 80% (range 40% to 90%). Use with other inducers has not been adequately studied.
MANAGEMENT: The efficacy of ramelteon may be reduced when prescribed with potent inducers of CYP450 isoenzymes such as carbamazepine, enzalutamide, phenobarbital, phenytoin, rifampin, and St. John's wort. Other known inducers include aminoglutethimide, bexarotene, bosentan, dabrafenib, dexamethasone, efavirenz, etravirine, mitotane, modafinil, nafcillin, nevirapine, rifabutin, rifapentine, barbiturates and various other anticonvulsants, although the extent to which they interact with ramelteon is unknown.
