28 Pa. Code § 25.51
The term "prescription" or "prescription order" means an order for a controlled substance, other drug, or device for medication which is dispensed to or for an ultimate user, but does not include an order for a controlled substance, other drug, or device for medication which is dispensed for immediate administration to the ultimate user. For example, an order to dispense a drug to a bed patient for immediate administration in a hospital is not a prescription order.
