NAQUIVAL vs TRIVARIS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
NAQUIVAL (trichlormethiazide) is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing electrolyte reabsorption and increasing urine output, thereby lowering blood pressure and reducing edema.
TRIVARIS combines an opioid agonist-antagonist (buprenorphine) and a mu-opioid receptor antagonist (naloxone). Buprenorphine partially binds to mu-opioid receptors, reducing withdrawal and craving, while naloxone precipitates withdrawal if injected, deterring abuse.
Adults: 0.1 mg/kg IV bolus, then 0.1 mg/kg/hour continuous IV infusion, titrated to clinical response. Maximum 0.5 mg/kg/hour.
TRIVARIS 10 mg orally once daily, with or without food.

Terminal elimination half-life: 14-16 hours (healthy adults). Extended to 26-35 hours in heart failure or hepatic cirrhosis due to reduced clearance.
Terminal half-life 12-18 hours; allows twice-daily dosing in chronic therapy
Renal: 50-60% as unchanged drug; fecal: <10% (biliary); remainder as metabolites (80% renal, 10% fecal).
Renal: 60% unchanged; Biliary/Fecal: 30% as metabolites; 10% minor pathways
