tablet


tablet
A solid dosage form containing medicinal substances with or without suitable diluents; it may vary in shape, size, and weight, and may be classed according to the method of manufacture, as compressed t.. SYN: tabule. [Fr. tablette, L. tabula]
- buccal t. usually a small, flat t. intended to be inserted in the buccal pouch, where the active ingredient is absorbed directly through the oral mucosa; such a t. dissolves or erodes slowly.
- compressed t. a t. prepared, usually as a large-scale production, by means of great pressure; most compressed tablets consist of the active ingredient and a diluent, binder, disintegrator, and lubricant.
- dispensing t. a t. prepared by molding or by compression; used by the dispensing pharmacist to obtain certain potent substances in a convenient form for accurate compounding. Formerly used to prepare bulk solutions of germicidal chemicals, e.g., bichloride of mercury. Not intended for internal use.
- enteric coated t. an oral dosage form in which a t. is coated with a material to prevent or minimize dissolution in the stomach but allow dissolution in the small intestine. This type of formulation either protects the stomach from a potentially irritating drug ( e.g., aspirin) or protects the drug ( e.g., erythromycin) from partial degradation in the acidic environment of the stomach.
- hypodermic t. a compressed or molded t. that dissolves completely in water to form an injectable solution.
- prolonged action t., repeat action t. SYN: sustained action t..
- sublingual t. usually a small, flat t. intended to be inserted beneath the tongue, where the active ingredient is absorbed directly through the oral mucosa; such a t. ( e.g., nitroglyerine) dissolves very promptly.
- sustained action t., sustained release t. a drug product formulation that provides the required dosage initially and then maintains or repeats it at desired intervals. SYN: prolonged action t., repeat action t..
- t. triturate a small, usually cylindrical, molded or compressed disk of varying size, containing a diluent usually consisting of dextrose (glucose) or of a mixture of lactose and powdered sucrose and a moistening agent or excipient, such as dilute alcohol.
