D-Lysine is a useful raw material employed as an analog of lutenizing-hormone-releasing hormone and as a drug carrier in the form of polylysine. D-Lysine decreases renal uptake of radioactivity during scintigraphy and PRRT with low toxicity. D-Lysine not interferes with the natural amino acid metabolic balance[1][2].
D-Lysine (400 mg/kg; i.v. or p.o.) dose not result in significantly greater inhibition of kidney uptake of '"In-DTPAOC, and Oral administration of D-lysine also reduces kidney uptake in rats[1].
