CLINICAL PHARMACOLOGY
Propoxyphene is a centrally acting narcotic analgesic agent. Equimolar
doses of propoxyphene
hydrochloride or napsylate provide similar plasma concentrations.
Following administration of 65, 130,
or 195 mg of propoxyphene hydrochloride, the bioavailability of
propoxyphene is equivalent to that of
100, 200, or 300 mg respectively of propoxyphene napsylate. Peak
plasma concentrations of

propoxyphene are reached in 2 to 2 /
hours. After a 65-mg oral dose of propoxyphene hydrochloride,
peak plasma levels of 0.05 to 0.1 mcg/mL are achieved. As shown in
Figure 1, the napsylate salt tends to
be absorbed more slowly than the hydrochloride. At or near therapeutic
doses, this absorption
difference is
