Medication is a broad term that refers to drugs used to treat various diseases and health conditions. Medication can be categorized into several types, including prescription, over-the-counter, and dietary supplements. Prescribed medications are typically prepared in tablet, capsule, syrup, or powder form and are often dispensed by a licensed healthcare professional. Over-the-counter medications, also known as OTC, are sold without a prescription and can be purchased without a doctor's visit. Dietary supplements, such as vitamins, minerals, and herbal remedies, are not considered medication but are allowed to be sold without a prescription.

They can also be used to alleviate pain, reduce inflammation, or抑制 the spread of infection. Many medications target chronic conditions, such as heart disease, diabetes, and hypertension. Additionally, medications are used to prevent disease, such as vaccines for infectious diseases.
Types of Medication
There are several types of medication, each with its own unique set of uses and effects.处方 medications are reserved for patients who are diagnosed with a condition that requires medical intervention.

Routes of Administration
Medications can be administered through several routes, including oral, intravenous (IV), intramuscular (IM), subcutaneous (SC), and transdermal.
