Oral dosage forms are medications designed to be taken by mouth. They come in various types, including tablets, capsules, and liquids. These forms allow for easy administration and are commonly used due to their convenience and effectiveness in delivering drugs to the body. Once ingested, oral dosage forms dissolve in the digestive system, releasing the active ingredients. This process allows the medication to be absorbed into the bloodstream, where it can exert its therapeutic effects. Common examples of oral dosage forms include acetaminophen tablets and liquid antibiotics.
