Medroxyprogesterone Injection (400 mg/mL) and Zorbtive

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.

Somatropin may decrease the blood levels and effects of medroxyPROGESTERone. You may need a dose adjustment if you have been taking medroxyPROGESTERone and are starting treatment with somatropin. Contact your doctor if your condition changes during treatment with these medications. The interaction is not expected to occur if you are getting medroxyPROGESTERone by shot for birth control. However, let your doctor know if you experience bleeding outside of your menstrual cycle, since it may indicate reduced effectiveness of medroxyPROGESTERone. 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.

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations and pharmacologic effects of medroxyprogesterone, which is primarily metabolized by the isoenzyme. Aminoglutethimide, a CYP450 3A4 inducer, has been shown to significantly decrease the serum levels of medroxyprogesterone by 50% or more when administered at 250 mg two to four times daily to women with breast cancer receiving high-dose medroxyprogesterone orally. The decrease was accompanied by an increase in serum cortisol level, which suggests diminished adrenal suppressive effect of medroxyprogesterone. The interaction has not been studied with depot formulations of medroxyprogesterone. Because the clearance of medroxyprogesterone is approximately equal to the rate of hepatic blood flow, drugs that induce CYP450 3A4 are not expected to significantly affect the pharmacokinetics of medroxyprogesterone administered parenterally. In one study, no interaction was reported when medroxyprogesterone was administered intravenously with aminoglutethimide.

MANAGEMENT: Pharmacologic response to medroxyprogesterone should be monitored more closely whenever a CYP450 3A4 inducer is added to or withdrawn from therapy, and the dosage adjusted as necessary. When administered as the depot formulation for contraception, no dosage adjustment for medroxyprogesterone is currently recommended during coadministration with CYP450 3A4 inducers. However, consideration may be given to decreasing the dosing interval (e.g., from one injection every 12 weeks to every 10 weeks) if an interaction is suspected.
