SEGLENTIS vs STERI-STAT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
SEGLENTIS is a fixed-dose combination of the opioid oxycodone and the opioid antagonist naltrexone. Oxycodone acts as a mu-opioid receptor agonist, providing analgesia. Naltrexone is intended to reduce the abuse potential of oxycodone by blocking opioid receptors when the drug is tampered with (e.g., crushed or chewed), but is sequestered in the core of the tablet and not released when taken orally as directed.
Binds to the 50S ribosomal subunit of bacteria, inhibiting protein synthesis by blocking peptide bond formation and translocation.
Subcutaneous injection: 300 mg (1.5 mL) once weekly. Administer in combination with oral capecitabine.
Adults: 1 gram intravenously every 8 hours infused over 60 minutes.

The terminal elimination half-life of celecoxib is approximately 11 hours; for tramadol, it is about 6 hours, and for its active M1 metabolite, about 7 hours. Clinically, this supports twice-daily dosing for Seglentis (two tablets BID).
Terminal elimination half-life is 8-12 hours in adults with normal renal function; prolonged to 18-24 hours in moderate renal impairment (CrCl 30-50 mL/min).
Seglentis (celecoxib and tramadol) is primarily excreted renally. Celecoxib is eliminated via hepatic metabolism (CYP2C9) with <3% excreted unchanged in urine; fecal excretion accounts for approximately 70% of an oral dose (as metabolites). Tramadol and its active metabolite (M1) are mainly excreted renally (about 90% of the dose, with 30% unchanged tramadol and 15% M1); the remainder is excreted fecally.
Renal excretion of unchanged drug accounts for approximately 95% of elimination; biliary/fecal elimination is minimal (<5%).
