Capsules and tablets are oral medications taken by mouth. Capsules typically contain powdered medication enclosed in a dissolvable shell, while tablets are compressed medication designed to dissolve after swallowing.

Injectable medications are sterile liquid formulations delivered with a syringe by the patient in the comfort of their home.

Nasal sprays deliver medication through the nasal passages using a spray device. The medication is absorbed through the nasal lining and administered without swallowing a pill or receiving an injection.

Topical medications are applied directly to the skin. These formulations may include creams, gels, ointments, or solutions designed for localized or transdermal application.

Troches are small medicated lozenges designed to dissolve slowly in the mouth, typically between the cheek and gum. The medication is absorbed through the oral mucosa as it dissolves.
