Aspirin and such refers to a group of medications known as analgesics, which are used to relieve pain. The term 'aspirin and such' is often used to refer to two specific types of analgesics: pills and esters. Pills are small, solid doses of medication that can be swallowed or taken orally. Esters are chemical compounds that are formed when an acid reacts with an alcohol. Aspirin and such are commonly used to treat headaches, muscle aches, and other minor pains.
