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.
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.

With stability testing, pharmaceutical industry inspects the quality of drug substances and drug products as per the guidelines outlined by US Food and Drug Administration and International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use to make sure that they retained the quality over the period of time.
Pharmaceutical tablet presses are required to be easy to clean and quick to reconfigure with different tooling, because they are usually used to manufacture many different products. There are two main standards of tablet tooling used in pharmaceutical industry: American standard TSM and European standard EU.
Friability and abrasion testing is performed in rotating testing drums, designed according to the pharmacopeia. The measured parameter is weight loss before and after testing and tumbling the tablets at a particular time and speed. In the friability test drum tablets are being carried up by a "shovel" and dropped.
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.

Such official endorsements are not winning policy debates. A recent windfall from the state’s settlements with pharmaceutical companies over allegations of corrupt practices has meant more than $30 million in new funding for addiction treatment and prevention programs. None of it is being used on medically assisted treatment.
Pharmaceutics deals with the formulation of a pure drug substance into a dosage form.Pure drug substances are usually white crystalline or amorphous powders. Before the advent of medicine as a science, it was common for pharmacists to dispense drugs as is.
