Studies of both human and nonhuman primates show an inverse relationship between high-density lipoprotein (HDL) cholesterol concentrations and coronary artery atherosclerosis. For this reason, there has been concern that the HDL cholesterol-lowering effect of oral contraceptives might exacerbate coronary artery atherosclerosis. We studied three groups of adult female cynomolgus macaques fed a moderately atherogenic diet: a control group, a group given ethinyl estradiol and norgestrel, and another group given ethinyl estradiol and ethynodiol diacetate. Norgestrel and ethynodiol diacetate, co-administered with ethinyl estradiol, lowered the plasma concentrations of HDL cholesterol. However, the extent of coronary artery atherosclerosis was lessened by both contraceptives, especially among females at high risk based on their plasma lipid profiles.

D009644 Norgestrel A synthetic progestational agent with actions similar to those of PROGESTERONE. This racemic or (+-)-form has about half the potency of the levo form (LEVONORGESTREL). Norgestrel is used as a contraceptive, ovulation inhibitor, and for the control of menstrual disorders and endometriosis. 18,19-Dinorpregn-4-en-20-yn-3-one, 13-ethyl-17-hydroxy-, (17alpha)-(+-)-,DL-Norgestrel,Neogest,Ovrette,Postinor,Wy-3707,DL Norgestrel,Wy 3707,Wy3707
