Question

Which of the following estrogen medications is not a transdermal dosage form?

a. climara
b. estraderm
c. premarin
d. vivelle

Answer 1

Premarin is an estrogen medication that is not available in a transdermal dosage form.

Step-by-step explanation:

The estrogen medication that is not a transdermal dosage form is premarin.

1. Climara is a transdermal patch that delivers estrogen through the skin.
2. Estraderm is also a transdermal patch that contains estrogen.
3. Vivelle is another transdermal patch formulation of estrogen.

However, premarin is available in the form of oral tablets, not transdermal patches. It contains a mixture of estrogens derived from pregnant mares' urine.
