Tablets
A tablet is a pharmaceutical dosage
form. It comprises a mixture of active substances and excipients, usually
in powder form, pressed or compacted into a solid. The compressed
tablet is the most popular dosage form in use today. About two-thirds
of all prescriptions are dispensed as solid dosage forms, and half of
these are tablets. A tablet can be formulated to deliver an accurate dosage to
a specific site; it is usually taken orally, but can be administered sublingually,
buccally, rectally or intravaginally. Medicinal tablets were
originally made in the shape of a disk of whatever color their components
determined, but are now made in many shapes and colors to help distinguish
different medicines. Tablets are often stamped with symbols, letters, and
numbers, which enable them to be identified. Sizes of tablets to be swallowed
range from a few millimeters to about a centimeter. Some tablets are in the
shape of capsules, and are called “caplets”.
