INDOCIN vs TENATHAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever. It also decreases renal blood flow and may cause ductus arteriosus closure.
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.
25 mg orally 2-3 times daily; maximum 200 mg/day. Intravenous: 0.5-1 mg/kg as single dose for ductus arteriosus closure.
1 tablet (40 mg) orally once daily, increased to 80 mg once daily if needed after 4 weeks.

Terminal elimination half-life approximately 4.5 hours (range 2.6–11.2 hours); prolonged in elderly and patients with hepatic 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.
Renal (60% as unchanged drug and glucuronide conjugates), biliary/fecal (33% via enterohepatic circulation).
Primarily renal excretion as unchanged drug (60-70%) and metabolites (20-30%); biliary/fecal elimination accounts for <10%.
