title: [Pain-relief effect of tramadol HCL capsule for moderate and severe cancer pain].
abstract: Fifty-one patients with moderate (11/51) and severe (40/51) cancer pain were given a new non-narcotic analgesic -Tromadol HCL capsule (THC). In 42 of these patients, partial relief was obtained with an average relief time (ART) of 4.1 hours. The average starting time was 58 minutes. Pain relief rate (PRR) in moderate and severe pain was 82% (P = 0.945), and the ARTs were 7.4 hr. and 3.2 hr., respectively (P = 0.005). In 43 patients who were entered into a randomized study with control drugs of AT-237 (36 cases) or Anfendein (7 cases), the PRR was 60.4% (26/43), ART was 1.3 hours. The PRR and ART of THC and control drugs were statistically significant (P less than 0.001 and P = 0.023). Within adequate dose range, increase of THC dose could improve its analgesic effect (P = 0.011). The main side-effects were: somnolence (37.3%), nausea (35.3%), dizziness (33.3%), palpitation and anorexia (25.5%) and constipation (9.8%) which did not necessitate the suspension of THC administration.
