KETOROLAC TROMETHAMINE vs TENATHAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ketorolac tromethamine is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby decreasing pain and inflammation.
TENATHAN is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the central nervous system by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane, leading to increased serotonin levels in the synaptic cleft.
10 mg orally every 4-6 hours, not to exceed 40 mg per day; or 15-30 mg intramuscularly or intravenously every 6 hours, not to exceed 120 mg per day (maximum 60 mg for single dose).
1 tablet (40 mg) orally once daily, increased to 80 mg once daily if needed after 4 weeks.

Terminal half-life is 5-6 hours in young adults, prolonged to 9-10 hours in elderly patients (≥65 years) and up to 12-15 hours in renal impairment (CrCl <30 mL/min). Context: q6h dosing interval recommended; accumulation risk in elderly/renal impairment.
Terminal elimination half-life is 4-6 hours; in severe renal impairment (CrCl <30 mL/min) may extend to 8-12 hours, requiring dose adjustment.
Primarily renal excretion: ~92% of dose excreted in urine as parent drug (60%) and metabolites (p-hydroxyketorolac, conjugated forms). Fecal excretion accounts for ~6%. Biliary excretion is minimal.
Primarily renal excretion as unchanged drug (60-70%) and metabolites (20-30%); biliary/fecal elimination accounts for <10%.
