Which type of medication can be administered via transdermal patches?

Transdermal patches are specifically designed to deliver medication through the skin into the bloodstream for systemic effects. Hormones and analgesics are well-suited for transdermal administration because they can provide steady drug delivery over an extended period, enhancing their therapeutic effects while minimizing peaks and troughs in drug levels.

For instance, hormone replacement therapies (like estrogen) and analgesics (like fentanyl for pain management) utilize this method effectively. The patches allow for a controlled release and convenient administration without the need for injections or frequent dosing.

Other types of medications listed may not be appropriate for transdermal delivery. For example, oral antibiotics typically require gastrointestinal absorption, and topical antiseptics are intended for localized application rather than systemic absorption. Thus, the transdermal route is optimal for specific classes of medications such as hormones and analgesics, making this answer the most accurate choice.
