Aspirin, also known as acetylsalicylic acid, is a salicylate drug. It is mostly used as an analgesic or painkiller. The active ingredient in aspirin is acetyl salicylic acid, which is a synthetic derivative of salicin compound. This compound is found naturally in plants, particularly the willow tree. It is the oldest and widely used analgesic available in the market. It is a non-steroidal anti-inflammatory drug (NSAID), which can be used to treat mild to moderate aches or pains. Some of them muscle aches, toothaches and headaches. It also treats ailments like common cold, fever and inflammation. There are coated and uncoated aspirins available in the market. The coated or enteric coated aspirin has a shiny and smooth layer over the tablet, whereas the non- coated one has a rough surface.
