Norelgestromin and estrogen; ATC-code.
It contains two active substances: norelgestromin(6 mg) and ethinyl estradiol 600 micrograms.
Mg norelgestromin and 600 micrograms ethinyl estradiol.
Each 20 cm2 transdermal patch contains 6 mg norelgestromin(NGMN) and 600 micrograms ethinyl estradiol EE.
The active substances in Evra are two hormones, ethinyl estradiol(an oestrogen) and norelgestromin a progestogen.
Norelgestromin and norgestrel(a serum metabolite of norelgestromin) are highly bound(> 97%) to serum proteins.
Data on reproductive toxicity of the combination of norelgestromin with ethinyl estradiol are not available.
Norelgestromin is bound to albumin and not to SHBG, while norgestrel is bound primarily to SHBG, which limits its biological activity.
EVRA acts through the mechanism of gonadotropin suppression by the estrogenic andprogestational actions of ethinyl estradiol and norelgestromin.
Steady state concentrations of norelgestromin and EE during one week of patch wear are approximately 0.8 ng/ ml and 50 pg/ ml, respectively.
Results from an EVRA study of extended wear of single contraceptive patch for 7 days and10 days indicated that target Css of norelgestromin and ethinyl estradiol were maintained during a 3-day period of extended wear of EVRA 10 days.
The results indicated that for norelgestromin there were no significant treatment effects on Css or AUC when compared to normal wear.
Evra should not be used by women who may be hypersensitive(allergic) to norelgestromin, ethinyl estradiol or any of the other ingredients.
Hepatic metabolism of norelgestromin occurs and metabolites include norgestrel, which is largely bound to SHBG, and various hydroxylated and conjugated metabolites.
However, only a small fraction(10- 20%)of the overall variability in the pharmacokinetics of the norelgestromin and EE following application of EVRA may be associated with any or all of the above demographic parameters.
The absorption of norelgestromin and ethinyl estradiol following application of EVRA was studied under conditions encountered in a health club(sauna, whirlpool, treadmill and other aerobic exercise) and in a cold water bath.
Following removal of a patch, the mean elimination half-lives of norelgestromin and ethinyl estradiol were approximately 28 hours and 17 hours, respectively.
With respect to the reproductive toxicity norelgestromin showed foetal toxicity in rabbits, but the safety margin for this effect was sufficiently high.
In multiple-dose studies, serum concentrations and AUC for norelgestromin and EE were found to increase only slightly over time when compared to week 1 cycle 1.
The combination of the synthetic ethinylestradiol and norelgestromin- which are artificial versions of oestrogen and progestogen, respectively- influence your body's natural cycle, so that you stop ovulating.
However, under the recommended dosing regimen, the in vivo concentrations of norelgestromin and its metabolites, even at the peak serum levels, are relatively low compared to the inhibitory constant(Ki), indicating a low potential for clinical interaction.
