How is a drug administered when it is injected directly into the body?

When a drug is administered by injection, it means that the medication is delivered directly into the body using a syringe and needle. This method allows for rapid absorption into the bloodstream, enabling the drug to work quickly and effectively.

Injecting medication can occur in various forms, such as intramuscular, subcutaneous, or intravenous, depending on the desired effect and the speed of action needed. This direct method bypasses the digestive system, unlike oral medications, which must be broken down and absorbed through the gastrointestinal tract.

By understanding the characteristics of drug administration methods, it becomes clear that the injection process is distinct and offers unique advantages in certain medical situations, making it the correct choice in this context.
