In the pharmaceutical industry, drug dissolution testing is routinely used to provide critical in vitro drug release information for both quality control purposes, i.e., to assess batch-to-batch consistency of solid oral dosage forms such as tablets, and drug development, i.e., to predict in vivo drug release profiles.

Tablet hardness testing is a laboratory technique used by the pharmaceutical industry to determine the breaking point and structural integrity of a tablet and find out how it changes "under conditions of storage, transportation, packaging and handling before usage" [1] The breaking point of a tablet is based on its shape.

A caplet is a smooth, coated, oval-shaped medicinal tablet in the general shape of a capsule. Many caplets have an indentation running down the middle, so they may be split in half more easily. [5] Consumers have viewed capsules as the most effective way to take medication ever since they first appeared.
The dosage should have a uniform appearance, with an acceptable taste, tablet hardness, and capsule disintegration. It is unlikely that formulation studies will be complete by the time clinical trials commence. This means that simple preparations are developed initially for use in phase I clinical trials.
Clonazepam ODT blister pack and tablet Etizest-1 MD (Etizest-brand 1mg-doskk etizolam mouth-dissolving (MD) blister pack and opened tablet. An orally disintegrating tablet or orally dissolving tablet (ODT) is a drug dosage form available for a limited range of over-the-counter (OTC) and prescription medications.
Friability testing is a laboratory technique used by the pharmaceutical industry to test the durability of tablets during transit. This testing involves repeatedly dropping a sample of tablets over a fixed time, using a rotating wheel with a baffle.
The hardness value of a tablet gives an early indication of the tablet's disintegration time. Further measured parameters are weight, thickness, diameter, disintegration time, friability, and abrasion. Friability and abrasion testing is performed in rotating testing drums, designed according to the pharmacopeia.
An enteric coating is a polymer barrier applied to oral medication that prevents its dissolution or disintegration in the gastric environment. [1] This helps by either protecting drugs from the acidity of the stomach, the stomach from the detrimental effects of the drug, or to release the drug after the stomach (usually in the upper tract of the intestine).
