Comparison of a narcotic (oxicone) and a non-narcotic anti-inflammatory analgesic (indoprofen) in the treatment of renal colic.
Intravenous indoprofen (400 mg), a cyclooxygenase inhibitor, was compared with intramuscular oxicodone hydrochloride (= oxicone 10 mg), a narcotic analgesic agent, in regard to efficacy and side effects in the treatment of renal colic. Oxicone was combined with papaverine (20 mg). Patients were randomized to either treatment, and the drugs were given in double-dummy fashion, i.e. one injection of active drug plus one placebo injection. Pain intensity before and after treatment was registered by the patient (visual analog scale) and by a nurse, who also registered side effects. Oxicone was given to 46 patients and indoprofen to 48. The groups did not differ in body weight, age, sex distribution, or pretreatment intensity of pain. More patients required additional treatment in the oxicone than in the indoprofen group (19 v. 10). At 2-5 min after injection, pain reduction was greater with indoprofen, and more patients in this group had pain relief after 3-5 hours. Side effects were less frequent with indoprofen than with oxicone (1 v. 20 patients), in particular from the central nervous system. This difference probably was related to indoprofen's slow and poor penetration of the blood-brain barrier. The study affirmed that non-narcotic cyclooxygenase inhibitors can replace narcotic analgesics for acute pain alleviation in renal colic. Indoprofen seems to be a useful alternative, with low risk of central nervous side effects.
