Could you please explain to me the benefits of intramuscular vs sub-cutaneous injections?
Answer Dear Jane Why reinvent the wheel? Ive been lazy here and have attached this information as written for my textbook. It is probably more detailed than you require but I am sure it will give you all the answers you need. Subcutaneous injections The blood supply to the subcutaneous tissue is poor, so absorption of an injected drug will be relatively slow.This is often an advantage with drugs that cannot be given by mouth.An example is the protein insulin, which would be digested if given orally; when injected intravenously, the resultant fast action is not always desirable. Absorption rate of drugs given by subcutaneous injection can be slowed down further by incorporating adrenaline in the injection. Adrenaline promotes vasoconstriction, which decreases the distribution of the injected material. This vasoconstriction will also decrease bleeding when adrenaline is injected with a local anaes-thetic for minor surgical procedures. Conversely, if the enzyme hyaluronidase is added to a
