Tablets are solid dosage forms Usu lly prepared with the aid of suitable pharmaceutical excipients
Tablets are solid dosage forms usually prepared with the aid of suitable pharmaceutical excipients
Tablets may vary in size, shape, weight hardness, thickness, disintegration, and dissolution characteristics and in other aspects, depending on their intended use and method of manufacture Tablets can be administered orally sublingually, buccally, or vaginally Tablets are prepared primarily y by compression, with a limited number prepared by molding
