Randomized Controlled Trial Clinical TrialA double-blind controlled trial of salmon calcitonin in pain due to malignancy.
Thirty-two patients with established malignancy and associated pain participated in a randomised double-blind controlled trial. They received salmon calcitonin SC 200 UI or matching placebo 6-hourly for 48 h and were assessed by using a combination of a 20-point visual analogue scale (VAS), a 4-point physician's global pain scale, and ranking of the co-administered analgesics into 20 grades of potency. ⋯ One week after commencing therapy there was improvement or marked improvement of pain in significantly more patients in the calcitonin group (5/13) than in the placebo group (0/12) (Fisher's exact two-tailed probability test, P = 0.0484). At the end of the second week three patients in the calcitonin group were still showing marked improvement.
