Double-blind study of the analgesic effect of indoprofen (K 4277)

In a double-blind study, indoprofen was superior to placebo in decreasing pain in patients with primary and metastatic cancer and with neuralgia. A single oral dose of 200 mg was more active than a 100-mg dose. The preferences of patients proved to be a more sensitive parameter in this study than scores of pain intensity, pain relief, and other related measurements (SPID, TOTPAR, and Peak PID).
