This study examines the effect of treatment with controlled-release poly(DL-lactide-coglycolide) microsphere formulations of the LH-RH agonist [D-Trp6, des-Gly-NH10(2)]-LH-RH ethylamide (LH-RH-A) designed to release about 100 or 200 micrograms of the peptide per day for 3, 5 or 6 months in male dogs. Plasma levels of testosterone and LH-RH-A were measured at 2-day intervals. After the first injection of the 100-micrograms/day formulation, plasma testosterone increased from 1.6 +/- 0.2 to 3.5… CONTINUE READING
