Randomized Controlled TrialAnalgesic efficacy of tramadol by route of administration in a clinical model of pain.
The objective of this study was to evaluate the analgesic efficacy produced by tramadol given by two different routes of administration in patients experiencing pain after removal of an impacted mandibular third molar under local anesthesia. A double-blind, randomized, placebo-controlled clinical trial was conducted. Patients were assigned into four groups of treatment, twelve subjects per group: Group A, tramadol 50 mg IM one hr before surgery; group B, tramadol 50 mg into the surgical site; group C, tramadol by both routes of administration, 50 mg IM one hr before surgery plus 50 mg into the surgical site; and group D, control. ⋯ However, only in the route combination group was a significant reduction in the requirement of acetaminophen observed. Nine patients requiring additional medication were treated with ketorolac 30 mg injected intramuscularly; 2 in the systemic group, 2 in the local group, 4 in the control group and only 1 in the combination group. Adverse events were minimal and similar in all groups.
