In the United States, a boxed warning (sometimes "black box warning", colloquially) is a type of warning that appears on the package insert for certain prescription drugs, so called because.

The United States Pharmacopoeia (USP) is a pharmacopoeia (compendium of drug information) for the United States published annually by the United States Pharmacopoeial Convention (usually also called the USP), a nonprofit organization that owns the trademark and copyright.

The USP is published in a combined volume with the National Formulary (a formulary) as the USP-NF.

If a drug ingredient or drug product has an applicable USP quality standard (in the form of a USP-NF monograph), it must conform in order to use the designation "USP" or "NF." Drugs subject to USP standards include both human drugs (prescription, over-the-counter, or otherwise), as well as animal drugs.

USP-NF standards also have a role in U.S. federal law; a drug or drug ingredient with a name recognized in USP-NF is deemed adulterated if it does not satisfy compendial standards for strength, quality or purity.

USP also sets standards for dietary supplements, and food ingredients (as part of the Food Chemicals Codex).

USP has no role in enforcing its standards; enforcement is the responsibility of FDA and other government authorities in the U.S. and elsewhere.

A tablet is a pharmaceutical dosage form.

Tablets may be defined as the solid unit dosage form of medicament or medicaments with or without suitable excipients and prepared either by molding or by compression.

It comprises a mixture of active substances and excipients, usually in powder form, pressed or compacted from a powder into a solid dose.

The excipients can include diluents, binders or granulating agents, glidants (flow aids) and lubricants to ensure efficient tabletting; disintegrants to promote tablet break-up in the digestive tract; sweeteners or flavours to enhance taste; and pigments to make the tablets visually attractive or aid in visual.

A polymer coating is often applied to make the tablet smoother and easier to swallow, to control the release rate of the active ingredient, to make it more resistant to the environment (extending its shelf life), or to enhance the tablet's appearance.
