Medicines are substances or compounds that are used to prevent, treat, or cure diseases, illnesses, or physical and mental disorders in humans and animals. They are typically administered orally, injected, applied topically, or inhaled, with the aim of restoring or improving health and well-being.
Medicines can be found in various forms such as pills, tablets, capsules, liquids, creams, ointments, and inhalers, and may be prescribed by healthcare professionals including doctors, nurses, dentists, or veterinarians. They are developed through extensive research, testing, and regulatory approval processes to ensure their effectiveness, safety, quality, and appropriate use.
The main purpose of medicines is to alleviate symptoms, manage chronic conditions, prevent the progression of diseases, or eradicate infections. They can act by different mechanisms, including targeting specific cells, enhancing the immune system, regulating body functions, or correcting chemical imbalances. Medicines often contain active pharmaceutical ingredients (APIs) that exert the desired therapeutic effect, along with other components known as excipients that serve various purposes such as ensuring stability, aiding absorption, or improving taste.
It is important to note that medicines should be used in accordance with healthcare professionals' advice, guidelines, or instructions to maximize their benefits and minimize potential risks or adverse effects. Adherence to prescribed dosage and duration is crucial to achieve the desired outcomes. Moreover, misuse, abuse, or inappropriate self-medication with medicines can lead to harmful consequences and should be avoided.
