Absorption is slow meaning in parenteral route?

In the parenteral route, absorption refers to the process by which a drug is taken up into the bloodstream after administration. When absorption is slow in the parenteral route, it means that the drug is being absorbed into the bloodstream at a slower rate compared to other routes of administration. This can result in a delayed onset of action and a longer duration of effect for the drug. Slow absorption in the parenteral route can be influenced by factors such as the formulation of the drug, the site of injection, and the characteristics of the individual receiving the drug.
