How is Aspirin Made?

Aspirin is made from four ingredients: acetylsalicylic acid with added corn starch and water serving as a binding agent and filler, and a lubricant to prevent the mixture from sticking to the machinery. Aspirin tables come in different shapes, weight, size, thickness, and hardness which is dependent upon the dosage amount. The aspirin is then packaged into various size plastic bottles, topped with cotton, sealed, and safety sealed with a clear plastic band to discourage product tampering. Various quality control measures are taken to test the aspirin to insure accurate dosage, table hardness, tablet disintegration, etc.
