FLUXID vs PREVACID IV
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FLUXID is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity by blocking the reuptake of serotonin at the presynaptic neuronal membrane, increasing serotonin availability in the synaptic cleft.
Lansoprazole is a proton pump inhibitor (PPI) that suppresses gastric acid secretion by specific inhibition of the (H+, K+)-ATPase enzyme system at the secretory surface of gastric parietal cells. This action is dose-related and leads to inhibition of both basal and stimulated gastric acid secretion.
1-2 g IV every 8 hours; maximum 6 g/day.
30 mg intravenous infusion over 30 minutes once daily for up to 7 days; may switch to oral therapy when patient can tolerate oral intake.

Terminal half-life: 12 hours (range 10–14 hours). In renal impairment (CrCl <30 mL/min), half-life prolonged to 24–36 hours; dose adjustment required.
Terminal elimination half-life is approximately 1.5–2 hours in healthy individuals; however, the pharmacodynamic half-life (duration of acid suppression) is longer (up to 24 hours) due to accumulation in parietal cell canaliculi.
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%.
Primarily hepatic metabolism via CYP2C19 and CYP3A4; approximately 75% excreted in urine as metabolites, with less than 1% as unchanged drug; about 20% eliminated in feces via bile.
