A Pharmaceutical Injection is the act of administering a liquid, especially a drug, into a person's body using a needle and a syringe. An injection is considered a form of administering drugs via the parenteral route, which refers to routes of administration which do not involve absorption in the digestive tract. This allows the medication to be absorbed more rapidly and avoid the first pass effect. Besides taking oral medicines for health problems or topical applications of medicines in the form of lotions and creams, there is a Pharmaceutical Injection, which is considered the most frequently used medical procedures.
