BISMUTH SUBSALICYLATE, METRONIDAZOLE AND TETRACYCLINE HYDROCHLORIDE vs OXY-KESSO-TETRA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bismuth subsalicylate exerts antimicrobial and anti-inflammatory effects via binding to gastrointestinal mucosa and inhibiting prostaglandin synthesis; metronidazole inhibits DNA synthesis by forming nitro radical anions; tetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit.
Oxycodone is a full opioid agonist with relative selectivity for the mu-opioid receptor, though it can interact with other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxycodone. Oxycodone is combined with aspirin (OXY-KESSO-TETRA) for analgesic synergy.
Each dose consists of 2 capsules (each containing bismuth subsalicylate 262.4 mg, metronidazole 250 mg, and tetracycline hydrochloride 375 mg) taken orally 3 times daily (after meals) for 10 days.
200 mg orally every 8 hours for 10 days.

Bismuth subsalicylate: Bismuth component ~5 days (accumulation risk), salicylate 2–3 hours; Metronidazole: 8 hours (increased in hepatic impairment); Tetracycline HCl: 6–12 hours (prolonged in renal impairment).
Terminal elimination half-life approximately 8-12 hours in adults with normal renal function; prolonged to 20-40 hours in moderate to severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
Bismuth subsalicylate: Renal excretion of salicylate and bismuth (bismuth largely fecal as insoluble sulfide); Metronidazole: Renal 60–80% (unchanged and metabolites), fecal 6–15%; Tetracycline HCl: Renal 60% unchanged, fecal 40% (biliary and direct excretion).
Primarily renal (60-70% as unchanged drug) via glomerular filtration and tubular secretion; approximately 20-30% is metabolized hepatically with metabolites excreted renally; less than 5% eliminated via bile/feces.
