Oral hypoglycemic agents are medications taken orally to reduce blood glucose levels in patients with type 2 diabetes. Oral contraceptives, also known as birth control pills, contain hormones that prevent pregnancy through several mechanisms of action. They work by inhibiting ovulation and thickening cervical mucus to prevent fertilization and implantation. Some common oral contraceptives contain estrogens like ethinyl estradiol or progestins like norethindrone or levonorgestrel. Both oral hypoglycemic agents and oral contraceptives are taken orally to achieve their effects.
