    1.Name:

    Levonorgestrel powder

     

    2.Levonorgestrel powder usage and dosing:

    1.Oral contraception:
    At low doses, Levonorgestrel powder is used in monophasicand triphasicformulations of combined oral contraceptive pills, with available monophasic doses ranging from 100-250μg, and triphasic doses of 50μg/75μg/125μg. It is combined with the estrogen ethinylestradiol in these formulations.
    At very low daily dose of 30μg, Levonorgestrel powder is used in some progestogen only pillformulations.

     

    2.Emergency contraception

    Levonorgestrel powder is used in emergency contraceptive pills (ECPs), both in a combined Yuzpe regimen which includes estrogen, and as a Levonorgestrel raw powder-only method. The Levonorgestrel powder-only method uses Levonorgestrel raw powder 1.5 mg (as a single dose or as two 0.75 mg doses 12 hours apart) taken within 3 days of unprotected sex, with one study indicating that beginning as late as 120 hours (5 days) after intercourse could be effective.
    The primary mechanism of action of Levonorgestrel raw powder as a progestogen-only emergency contraceptive pill is, according to International Federation of Gynecology and Obstetrics (FIGO), to prevent fertilization by inhibition of ovulation and thickening of cervical mucus.FIGO has stated that: “review of the evidence suggests that LNG [levonorgestreol] ECPs cannot prevent implantation of a fertilized egg. Language on implantation should not be included in LNG ECP product labeling.” In November 2013, the European Medicines Agency (EMA) approved a change to the label saying it cannot prevent implantation of a fertilized egg. Other studies still find the evidence to be unclear. While it is unlikely that emergency contraception affects implantation it is impossible to completely exclude the possibility of post-fertilization effect. In November 2013, the EMA also approved a change to the label for HRA Pharma’s NorLevo saying: “In clinical trials, contraceptive efficacy was reduced in women weighing 75 kg [165 pounds] or more, and Levonorgestrel powder was not effective in women who weighed more than 80 kg .”In November 2013 and January 2014, the FDA and the EMA said they were reviewing whether increased weight and body mass index (BMI) reduce the efficacy of emergency contraceptives
