PIROXICAM vs TENATHAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby decreasing inflammation, pain, and fever.
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.
10-20 mg orally once daily; maximum 20 mg/day.
1 tablet (40 mg) orally once daily, increased to 80 mg once daily if needed after 4 weeks.

Terminal elimination half-life is 50 hours (range 30-86 hours), allowing once-daily dosing. Prolonged in elderly (up to 80 hours) and in hepatic impairment.
Clinical Note
moderatePiroxicam + Gatifloxacin
"Piroxicam may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderatePiroxicam + Rosoxacin
"Piroxicam may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderatePiroxicam + Levofloxacin
"Piroxicam may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderatePiroxicam + Trovafloxacin
"Piroxicam may increase the neuroexcitatory activities of Trovafloxacin."
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.
Approximately 60-70% renal (glomerular filtration and tubular secretion) as unchanged drug and metabolites; 30-40% fecal via biliary excretion. Less than 5% as unchanged drug in urine.
Primarily renal excretion as unchanged drug (60-70%) and metabolites (20-30%); biliary/fecal elimination accounts for <10%.
