Accutane is an analog of which vitamin?

Accutane, known generically as isotretinoin, is a medication primarily used to treat severe acne. It is a derivative of vitamin A, which is crucial for several bodily functions, including vision, immunity, and skin health. Isotretinoin works by decreasing oil production in the skin and making it less prone to form acne.

Vitamin A, or retinoids, are essential for maintaining healthy skin, and their analogs, like Accutane, are specifically designed to modulate skin cell functions. This is why Accutane is classified as a vitamin A analog.

The other options, while representing other important vitamins, do not relate to the mechanism or structure of Accutane. Vitamin C is primarily known for its antioxidant properties, Vitamin B comprises a group of vitamins important for energy production and metabolism, and Vitamin D is crucial for bone health but does not play a role in the skin conditions that Accutane primarily addresses. Thus, the connection of Accutane to vitamin A makes it the accurate choice in this context.
