Which injection solution base will result in the slowest absorption?

Question

Quizplus · Accepted Answer

Oil-based solutions are known to have the slowest absorption rate because they are less water-soluble, and the lipid barrier slows down their distribution in the body. Therefore, oil-based injections have a sustained release effect, prolonging their therapeutic efficacy. On the other hand, alcohol, saline, and water-based solutions tend to have a faster absorption rate due to their water solubility and the hydrophilic nature of body tissues.
