Pain control is essential to quality patient care. Analgesics ensure patient comfort. They can have side effects such as sedation, constipation, or, rarely, respiratory depression.

Morphine (Duramorph, Astramorph, MS Contin)

The opioid used most often; many physicians are probably more comfortable with this medication than other opioids. However, other available opioids can also be used in pain control. Starting dose may depend on whether patient is already taking narcotic analgesics. Large doses required in patients who have been taking opioid analgesics for a long time. Available orally in both immediate-release and timed-release preparations. Long-acting form usually dosed q12h, but many authorities believe it loses much of its effect after 8 h. Immediate-release form may be needed for periods of pain "breakthrough." Treatment should begin at the lowest available dose in newly diagnosed patients. Available preparations of oral morphine include MSIR, MS Contin, Oramorph, RMS (Purdue Frederick), and Roxanol (Roxane).
