Dexamethasone is a common pharmaceutical that falls into the ____ category.

  1. Antibiotic.

  2. Analgesic.

  3. Sedative.

  4. Steroid.

The correct answer is: Steroid.

Dexamethasone is classified as a steroid because it is a synthetic form of a hormone called cortisol, which is naturally produced in the body. Steroids are used to reduce inflammation and help control a variety of conditions, such as allergic reactions, skin diseases, and arthritis. Antibiotics, on the other hand, are used to treat bacterial infections while analgesics are used to alleviate pain. Sedatives are prescribed to induce sleep or relaxation. Therefore, options A, B, and C are incorrect categories for dexamethasone.
