In a hospital setting, an intravenous PCA (IV PCA) refers to an electronically controlled infusion pump that delivers an amount of analgesic when the patient presses a button. [4] IV PCA can be used for both acute and chronic pain patients. It is commonly used for post-operative pain management, and for end-stage cancer patients. [5]
Extended-release (or slow-release) formulations of morphine are those whose effect last substantially longer than bare morphine, availing for, e.g., one administration per day. Conversion between extended-release and immediate-release (or "regular") morphine is easier than conversion to or from an equianalgesic dose of another opioid with ...
The implantable medical device requires a surgical procedure; sometimes a surgeon performs a trial intrathecal injection or implants a temporary intrathecal catheter and pump to determine if the medication works to begin with, and thus if a pump is appropriate. A permanent intrathecal pump is then implanted if the patient derives at least 50% ...
In pharmacokinetics, the rate of infusion (or dosing rate) refers not just to the rate at which a drug is administered, but the desired rate at which a drug should be administered to achieve a steady state of a fixed dose which has been demonstrated to be therapeutically effective. Abbreviations include K in, [1] K 0, [2] or R 0.

Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.

Routes of administration are usually classified by application location (or exposition). The route or course the active substance takes from application location to the location where it has its target effect is usually rather a matter of pharmacokinetics (concerning the processes of uptake, distribution, and elimination of drugs).
