Randomized Controlled Trial Clinical Trial
Dose response and safety of cizolirtine citrate (E-4018) in patients with pain following extraction of third molars.
The objectives of this study were to determine the dose response and safety of the oral analgesic cizolirtine citrate (E-4018) in patients with postoperative pain after third molar extraction. This was a placebo-controlled, double-blind, randomised, parallel-group study. Doses of E-4018 were 50 mg, 100 mg, or 150 mg. ⋯ We conclude that there was a dose-related trend in the percentage of patients requiring paracetamol within five hours of their study medication, and in the percentage of patients that recorded the treatment as providing good or excellent treatment of pain. There was, however, no firm evidence of a dose-related analgesic effect over the dose range of Cizolirtine chosen for this study. E-4018 was well tolerated in all patients.
