Methimazole is used to treat hyperthyroidism in cats. It works by blocking the thyroid gland from making thyroid hormone. The effect is temporary. Most cats with hyperthyroidism require lifelong treatment with methimazole unless other, permanent treatment options are pursued. More details on these options are available on the page entitled Hyperthyroidism in Cats.
Enalapril and benazepril are related members of a class of drugs called ACE inhibitors. They have similar effects and uses in veterinary medicine.
In veterinary medicine, sulfadimethoxine is used primarily to treat coccidia (Isospora) in puppies and kittens. Courses of sulfadimethoxine generally last from 3 to 21 days.
Sulfadimethoxine also may be used as an antibiotic, but this is not common in veterinary medicine.
Sulfadimethoxine is currently considered an inferior treatment option for coccidia. A different drug, ponazuril, is preferred.
Antihistamines such as hydroxyzine (Atarax®), diphenhydramine (Benadryl®), and chlorpheniramine (Chlor-Trimeton®) are used in veterinary medicine primarily to treat allergies that cause skin problems.

Cimetidine, ranitidine, and famotidine are related medicines. They are in a class of drugs called H2 blockers. They have similar effects and uses in veterinary medicine.
H2 blockers cause decreased production of stomach acid. In pets, these medicines are prescribed mainly to treat or prevent gastrointestinal upset (vomiting, diarrhea, or lack of appetite). They also may be used to prevent or treat ulcers or irritation of the esophagus, stomach, or intestines.
