Abstract:
Intradermal injection of antigen can theoretically produce the same antibody response as 10-20% of the volume required for subcutaneous injection. This paper demonstrates equal efficacy of intradermal injection of Fluviral vaccine as compared to subcutaneous injection in an ambulatory geriatric population. There was no difference in adverse reactions between the two groups. A significant portion of both groups did not develop protective HAI antibody level to or more than 1/40.

Overview
01:29Drug Delivery: Parenteral Route
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

01:25Routes of Drug Administration: Parenteral
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
