Priority 12 from the Contraception PSP

UNCERTAINTY: What are the benefits and risks of using micronised progestogen or newer progestogens (such as Nomegestrol acetate, drospirenone) either in pill form or in long acting preparations, such as implants or in combined hormonal contraception?  (JLA PSP Priority 12)
Overall ranking 12
JLA question ID 0049/12
Explanatory note Newer progestogens such as drosperinone are derived from spironolactone rather than 19-nor testosterone. Compared to placebo the drosperinone ethinyl estradiol pill seemed to help women with severed symptoms in the short term, the placebo also had a positive effect. his may have an influence on fluid balance, and reduce side effects. Differences between progestogens were minimal in the systematic review comparing different formulations- it was noted the RCTs in the quality of the evidence was low, outcomes were unblinded, 23/33 RCTs were sponsored by the pharmaceutical companies. The potential risks of newer progestogens is uncertain.  Further double-blind comparisons of the side-effect and benefit profiles of new progestogens versus the earlier progestogens in combined and progestogen only contraception is needed to evaluate the benefits and common side effects of these preparations.
