The administration of medication via the subcutaneous route is typically chosen for medications that require a slow and steady absorption into the bloodstream. Insulin is a prime example of this, as it is designed to manage blood glucose levels in individuals with diabetes. The subcutaneous tissue contains fat and fewer blood vessels than muscle tissue, which allows for the gradual release of insulin into the bloodstream. This slow absorption is crucial for maintaining stable blood glucose levels throughout the day.

Medroxyprogesterone, while it can sometimes be injected, is more commonly given intramuscularly for long-acting effects, especially in contraceptive forms. Penicillin, particularly in its injectable forms, is often administered intramuscularly rather than subcutaneously due to its pharmacokinetics and the need for more immediate effects. Vaccines, including those for tetanus, are generally given intramuscularly as well to provide a more robust immune response. Thus, among the given options, insulin is indeed the medication that is most commonly administered via the subcutaneous route.
