Different types of tablets are formulated by the pharmaceutical industry, according to the route of administration and function. They can be different in size, weight, shape, thickness, hardness, disintegration and dissolution characteristics, and other features based on their amount of medicinal substances, intended use, and process of preparation.
The dosage form is a pharmaceutical formulation in which a particular mixture of active pharmaceutical ingredients (APIs) and excipients are used to allow simple and precise administration and delivery of active drug substances. Generally, it is classified based on the physical state, route of administration, site of application, and uses.
The tablet type of oral solid dosage form and is one of the most preferred compared to another form of medicine because it offers several applications and advantages to patients, physicians, and manufacturers. A tablet contains a mixture of active pharmaceutical ingredients (API/drug) and excipients, typically in powder form which is compressed to form a solid pill.
