FLURBIPROFEN vs PROPOXYPHENE HYDROCHLORIDE W/ ASPIRIN AND CAFFEINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cyclooxygenase (COX) inhibitor, reducing prostaglandin synthesis; nonsteroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic, and antipyretic effects.
Propoxyphene is a centrally acting opioid analgesic that binds to mu-opioid receptors. Aspirin inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis. Caffeine is a CNS stimulant that may enhance analgesia.
Oral: 50-100 mg every 6-8 hours; maximum 300 mg/day. Ophthalmic: 1 drop every 30 minutes starting 2 hours before surgery, then 1 drop every 4-6 hours for 24-48 hours post-surgery.
1-2 capsules orally every 4-6 hours as needed; maximum 6 capsules per day. Each capsule contains propoxyphene hydrochloride 65 mg, aspirin 325 mg, and caffeine 32.4 mg.

Terminal elimination half-life: 3-4 hours (healthy adults) in short-term use; prolonged to 6-12 hours in elderly or renal impairment.
Propoxyphene: 6-12 hours (up to 36 hours in overdose); norpropoxyphene: 30-36 hours. Aspirin: 2-3 hours for low doses, up to 15-30 hours in overdose. Caffeine: 3-6 hours; prolonged in liver disease.
Renal: 70% as conjugated metabolites (e.g., glucuronides) and <5% unchanged; biliary/fecal: 30%, with enterohepatic circulation.
Renal elimination of propoxyphene and its metabolites (mainly norpropoxyphene) accounts for approximately 70-90% of the dose; fecal excretion is minimal (<10%). Aspirin is renally eliminated as salicylates (75-90% as conjugates, 10% free), while caffeine is primarily metabolized and its metabolites are excreted renally.
