OXY-KESSO-TETRA vs ROBITET
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Robitussin (Robitet) is a combination product containing the antitussive dextromethorphan and the expectorant guaifenesin. Dextromethorphan acts centrally on the cough center in the medulla oblongata by increasing the threshold for coughing, primarily through sigma-1 receptor agonism and NMDA receptor antagonism. Guaifenesin increases the hydration of respiratory tract secretions, reducing mucus viscosity and facilitating expectoration.
200 mg orally every 8 hours for 10 days.
Tetracycline hydrochloride: 250-500 mg orally every 6 hours; maximum 4 g/day.

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.
Terminal elimination half-life: 3.5 hours (2.6–4.8 h) in adults; prolonged to 6–12 h in severe renal impairment
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.
Renal: 30% unchanged; biliary/fecal: 50% as metabolites; remainder metabolized
