Which of the following drug delivery systems can provide steady release of medication over time?

Transdermal system
Intramuscular injection
Oral tablets
Sublingual tablets

The correct answer is: Transdermal system

The transdermal system is designed specifically to enable the continuous and steady release of medication over an extended period of time. It consists of a patch that is applied to the skin, allowing the medication to be absorbed through the dermis and into the bloodstream. This method provides a consistent therapeutic level of the drug, reducing the peaks and troughs associated with other delivery methods. In contrast, intramuscular injections typically deliver a bolus of medication that may provide immediate effects, but the release is not controlled over a long duration. Oral tablets may also provide steady release, but they can vary significantly based on digestion and metabolism, and not all oral formulations are designed to be extended-release. Sublingual tablets provide rapid absorption through the mucous membranes but do not release medication steadily over time, as they dissolve quickly in the mouth and enter systemic circulation immediately. Thus, the transdermal system is the most suitable option for achieving a steady and controlled release of medication.
