Medications, also known as medicines or drugs, are substances or compounds that are used to prevent, treat, or relieve symptoms of diseases, medical conditions, or injuries. They are specifically designed to have therapeutic effects on the human body. Medications can be derived from both natural sources, such as plants and animals, or synthesized through a combination of chemical processes in laboratories.
These substances are typically ingested, injected, applied externally, or inhaled, and they work by interacting with the physiological processes or biochemical pathways in the body to restore or maintain health. Medications may target specific organs, systems, or cells to address specific conditions or alleviate symptoms. They can vary greatly in their composition, including active ingredients, excipients, and additives, all of which contribute to their effectiveness and safety.
Medications can be prescribed by licensed healthcare professionals, such as doctors, physician assistants, or nurse practitioners, following a thorough diagnosis and assessment of an individual’s medical condition. However, some medications are also available over-the-counter (OTC) and can be purchased without a prescription.
It is important to note that medications should always be taken as directed and in the appropriate dosage. Failure to do so can lead to harmful side effects or reduced efficacy. Additionally, some medications may have contraindications, interactions with other medications or substances, or specific instructions for administration, which should be carefully followed to ensure safety and effectiveness.
