Carbohydrate studies in women using a norethindrone triphasic oral contraceptive for eighteen months

  • Published:
Advances in Contraception

Abstract

Twenty women were tested before and after eighteen months of use of triphasic oral contraceptive (TOC) containing norethindrone and ethinyl estradiol (7-7-7). The evaluation was with an oral glucose tolerance test and plasma glucose and insulin levels were measured. The results showed a lower fasting glucose and elevated one-hour insulin values after TOC use. These results suggest improved safety with these contraceptives.

Resumé

Vingt femmes ont été examinées avant et après dix-huit mois d'utilisation d'un contraceptif oral triphasique (TOC) contenant du noréthindrone et de l'éthinylestradiol (7-7-7). L'évaluation s'est faite à l'aide d'un test oral de tolérance au glucose, au cours duquel on a mesuré les niveaux plasmatiques du glucose et de l'insuline. Les résultats ont montré qu'après utilisation du contraceptif oral triphasique les valeurs sont maintenues à un niveau inférieur à jeun et qu'il se produit une élévation de l'insuline pendant une heure. Ces résultats laissent penser que ces contraceptifs offrent une plus grande sécurité.

Resumen

Veinte mujeres fueron examinadas antes y después de dieciocho meses de utilización de un anticonceptivo oral trifásico (TOC) que contenía noretindrona y etinil estradiol (7-7-7). La evaluación se hizo mediante una prucba oral de tolerancia a la glucosa, en el curso de la cual se midieron los niveles plasmáticos de la glucosa e insulina. Los resultados mostraron que después de la utilización del TOC los valores se mantienen a un nivel inferior en el ayuno y que se produce un aumento de la insulina durante una hora. Estos resultados sugieren que estos anticonceptivos ofrecen mayor seguridad.
