NEPHROFLOW vs PYLARIFY TRUVU
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
NEPHROFLOW is a vasodilator that increases renal blood flow by selectively dilating afferent arterioles, leading to enhanced glomerular filtration rate (GFR). It also inhibits sodium reabsorption in the proximal tubule, promoting diuresis.
PYLARIFY is a PSMA-targeted PET imaging agent composed of a urea-based PSMA ligand (piflufolastat) labeled with fluorine-18. It binds to prostate-specific membrane antigen (PSMA) on prostate cancer cells, allowing PET imaging for detection of PSMA-positive lesions.
NEPHROFLOW (Ioversol) 350 mg iodine/mL: 1 mL/kg intravenously up to 150 mL maximum for contrast imaging.
1 mg/kg intravenously every 3 months.

4.2 hours (terminal) in normal renal function; prolongs in CKD.
Terminal elimination half-life: approximately 77 hours (range 68-85 hours) in patients with prostate cancer. This supports a 2-week dosing interval for single-photon emission computed tomography (SPECT) imaging.
Primarily renal (85% unchanged); 15% biliary/fecal. In renal impairment, half-life doubles.
Renal excretion: approximately 93% (3% unchanged, 97% as metabolites). Fecal excretion: approximately 5%. Biliary excretion is negligible.
