Administration routes refer to the various methods used to deliver medications or treatments to patients. Common routes include oral (by mouth), intravenous (directly into the bloodstream), intramuscular (into a muscle), and subcutaneous (under the skin). Each route has its own advantages and disadvantages, affecting how quickly and effectively the medication works. Choosing the appropriate administration route depends on several factors, including the type of medication, the desired speed of action, and the patient's condition. For example, intravenous administration allows for rapid effects, while oral administration is often more convenient and easier for patients to manage.
