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.

Non-steroidal anti-inflammatory drugs (NSAIDs) are currently considered a first-line treatment of renal colic. Their action has been ascribed to the inhibition of renal prostaglandin synthesis, which decreases renal blood flow and diuresis, and consequently lowers the pressure in the renal pelvis and ureter. However, the effects of NSAIDs on induced contractions of ureteral smooth muscle have received little attention. Also, there is a lack of clinically relevant spasmolytic drugs for the ureter. Therefore, we studied the influence of the non-selective cyclooxygenase (COX) inhibitor diclofenac, a NSAID drug customarily used in the treatment of renal colic, and of NS-398, a selective COX-2 inhibitor, on induced contractions of the pig ureter. Serotonin (0.1-30 microM), norepinephrine (0.1-30 microM) and neurokinin A (0.03-10 microM) induced reproducible concentration-dependent contractions, which were inhibited by diclofenac and NS-398 (10-300 microM) in a concentration-dependent manner. The sensitivity of neurokinin A-induced contractions to diclofenac was 3-4 times greater than that of the amines. Depending on the concentration, inhibition ranged between 25 and 96% of the initially induced contractile activity. In the presence of inhibitors, supramaximal concentrations of agonists were unable to trigger recuperation of the initially induced contractions. Prostaglandin F2alpha did not reverse the effect of diclofenac on agonist-induced contractions. Removal of diclofenac or NS-398 from the organ baths showed that the inhibition was totally reversible. Thus, the non-selective COX inhibitor diclofenac and the selective COX-2 inhibitor NS-398 are almost equipotent in reducing agonist-induced contractions in the isolated porcine ureter. Although the clinical relevance of this spasmolytic effect remains to be demonstrated, the data suggest that patients suffering from renal colic may benefit not only from the anti-diuretic and analgesic effects of diclofenac, but also from its potential spasmolytic properties. Moreover, selective COX-2 inhibitors may have clinical potential, as they may cause fewer side effects.
