Why subcutaneous injection is the slowest?

Why subcutaneous injection is the slowest?

As subcutaneous tissue has few blood vessels, the injected drug is diffused very slowly at a sustained rate of absorption.

Which of the injection route have the longest absorption time?

Intradermal injections (ID) are injections administered into the dermis, just below the epidermis. The ID injection route has the longest absorption time of all parenteral routes.

Which is faster absorption intramuscular or subcutaneous?

Intramuscular injections are absorbed faster than subcutaneous injections. This is because muscle tissue has a greater blood supply than the tissue just under the skin. Muscle tissue can also hold a larger volume of medication than subcutaneous tissue.

The intravenous route is known to be the fastest way to deliver drugs into the human body and hydrophilic drugs reach 100% of bioavailability.

Why intraperitoneal injection is faster?

Drug that is absorbed from the peritoneal cavity by the portal system is subjected to hepatic first-pass elimination. The fast uptake of drug from the peritoneal cavity will result in a more rapid saturation of the drug metabolizing enzymes than following oral administration.

How is a subcutaneous injection absorbed?

A subcutaneous injection or shot is one into the fatty tissues just beneath the skin. These injections are shallower than those injected into muscle tissues. Providers often use subcutaneous injections for medications that must be absorbed into the bloodstream slowly and steadily, such as insulin.

Which route of administration has the slowest onset of action?

subcutaneous
The intravenous route provides immediate onset of action. The intramuscular and subcutaneous routes can be used to achieve slow or delayed onset of action.

Which parenteral route of administration has the longest absorption time?

ID injection route
