LIQREV vs NUTRILIPID 20%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Liqrev (sildenafil) is a phosphodiesterase-5 (PDE5) inhibitor. It enhances the effect of nitric oxide by inhibiting PDE5, which degrades cGMP in the corpus cavernosum, leading to increased cGMP levels and smooth muscle relaxation, thereby facilitating penile erection.
Nutrilipid 20% is an intravenous fat emulsion providing a source of calories and essential fatty acids. It is composed of soybean oil, egg yolk phospholipids, and glycerin. The triglycerides in the emulsion are hydrolyzed by lipoprotein lipase into free fatty acids and glycerol, which are then metabolized for energy production and incorporation into cell membranes.
LIQREV (ivermectin) 200 mcg/kg orally once, taken on an empty stomach with water.
Intravenous infusion of 20% lipid emulsion: 1-2 g/kg/day (5-10 mL/kg/day) as part of parenteral nutrition; maximum infusion rate: 0.11 g/kg/h (0.55 mL/kg/h).

Terminal elimination half-life is 12–15 hours in healthy adults; prolonged to 24–30 hours in moderate renal impairment (CrCl <50 mL/min).
The terminal elimination half-life of triglycerides in NUTRILIPID 20% is approximately 30 minutes in healthy adults with normal lipid metabolism. In critically ill or lipemic patients, clearance is delayed, and half-life can exceed 6 hours, necessitating monitoring of serum triglycerides.
Primarily renal (70% as unchanged drug, 15% as glucuronide conjugate); 10% biliary/fecal.
NUTRILIPID 20% is a lipid emulsion; triglycerides are cleared from plasma via hydrolysis by lipoprotein lipase into free fatty acids and glycerol, which are then metabolized. Renal excretion of intact triglycerides is negligible (<1%); elimination is primarily metabolic, with less than 5% excreted unchanged in urine or feces.
