FAQs

Q1: Which estrogen preparations are commonly used for hormonal disorders?
Common estrogens include estradiol, ethinylestradiol, and conjugated equine estrogens. They are used in hormone replacement therapy and for conditions like primary ovarian failure. They are also used in contraceptive formulations.

Q2: How do combined oral contraceptive pills prevent pregnancy?
Combined pills contain estrogen and progestin. They mainly inhibit ovulation by suppressing gonadotropin release, and also thicken cervical mucus and alter the endometrium.

Q3: What drugs are used for medical termination of pregnancy?
The most common regimen is mifepristone followed by misoprostol. Mifepristone blocks progesterone receptors, and misoprostol causes uterine contractions to expel the pregnancy.

Q4: Why is diethylstilbestrol contraindicated during pregnancy?
Diethylstilbestrol is a synthetic nonsteroidal estrogen that is teratogenic. It can cause vaginal clear cell adenocarcinoma and reproductive tract abnormalities in offspring exposed in utero.

Q5: What are selective estrogen receptor modulators (SERMs) and give two examples?
SERMs are drugs that act as estrogen agonists in some tissues and antagonists in others. Tamoxifen is used in breast cancer, while raloxifene is used for osteoporosis.
