Question

Misoprostol used in the induction of labour is an analogue of which of the following type of prostaglandin ?

• A. PG E₁
• B. PG E₂
• C. PG I₂
• D. PG F₂ alpha

Answer 1

The Correct Option is A

Misoprostol is a medication used to induce labor. It is an analogue of a particular type of prostaglandin, designed to mimic the effects of naturally occurring prostaglandins in the body.

The question asks which prostaglandin misoprostol is an analogue of, providing the following options:

• PG E₁
• PG E₂
• PG I₂
• PG F₂ alpha

Misoprostol is an analogue of prostaglandin PG E₁. It binds to the prostaglandin E receptor, causing the cervix to dilate and uterine contractions to occur, aiding in the induction of labor. This specific action is aligned with the properties of PG E₁ analogues, making PG E₁ the correct choice.

Therefore, the correct option is:

PG E₁
