Dosage forms refer to the various ways in which medications are prepared and delivered to patients. Common types include tablets, capsules, liquids, and injections. Each form is designed to ensure the proper release and absorption of the active ingredient in the body, making it easier for patients to take their medications. The choice of dosage form can depend on several factors, including the type of medication, the condition being treated, and patient preferences. For example, liquids may be preferred for children or those with difficulty swallowing, while injections are often used for rapid action or when oral administration is not possible.
