Analgesic comparison of propiram fumarate with pentazocine, codeine, and placebo in postsurgical pain.

The safety and effectiveness of a single oral dose of 50 mg propiram fumarate as an analgesic was compared in a double-blind clinical trial trial against single doses of standard reference analgesics (50 mg pentazocine hydrochloride or 60 mg codeine sulfate) or placebo. Subjects were adult patients experiencing severe postsurgical pain. Mean pain scores and SPID scores showed all three active drugs to be favored (P less than 0.05) over placebo in patients with severe initial pain. The most common side effects seen were drowsiness, nausea, and dizziness. These were not severe enough to require treatment. Propiram fumarate (50 mg) was shown to be an effective and safe analgesic in the treatment of severe postsurgical pain.
