When a healthcare provider prescribes a medication, the "form" of that medicine is just as important as the active ingredient itself. A drug's dosage form—whether it is a hard tablet, a thick ointment, or a slow-release capsule—determines how quickly the body absorbs the chemical, how long the effect lasts, and how much irritation it might cause to the digestive tract. Understanding these various preparations is essential for ensuring patient safety and therapeutic effectiveness.
Solid Oral Preparations
Solid oral medications are among the most common forms of drug administration due to their stability and ease of use. These preparations are designed to be swallowed or held in the mouth to deliver a precise dose of medication.
Tablets and Capsules
The tablet is a compressed hard disk made of powdered medication. Some tablets are scored, meaning they have a groove that allows them to be easily broken into smaller, equal doses. To improve ease of swallowing or to protect the drug, tablets may also feature sugar or film coatings.
In contrast, a capsule consists of a gelatinous container that holds either liquid or powder medicine. A more advanced version of this is the spansule, which is a specialized time-release capsule designed to dissolve slowly, providing a prolonged therapeutic effect over a long period.
Specialized Solid Forms
Not all solids are meant to be swallowed whole. A lozenge (or troche) is a tablet specifically designed to be held in the mouth so that it can dissolve slowly. Additionally, some medications come as a powder, which consists of finely ground drug particles that are frequently mixed with a liquid immediately before administration.
