The abbreviation "TD" stands for "transdermal," which refers to the method of administering medication through the skin. This route allows for the gradual release of the drug into the bloodstream, providing a continuous effect over time. Transdermal systems are commonly used for medications such as pain relief patches or hormone replacement therapy, where a stable and prolonged therapeutic effect is needed without frequent dosing.

The other abbreviations do not refer to transdermal administration. "PR" signifies "per rectum," indicating a route of administration through the rectum, commonly used for medications that need to be absorbed quickly or for patients who are unable to take oral medications. "INH" stands for "inhalation," which is a method of delivering medication directly to the lungs, often used for respiratory conditions. "neb" refers to "nebulizer," a device used to convert liquid medication into a mist for inhalation, primarily for respiratory treatments. Understanding these distinctions is crucial for accurately interpreting medication directions and ensuring proper administration routes.
