摘要

Two new crystalline forms of 1S-[1alpha(2S*, 3R*), 9alpha]6, 10-dioxo-N-(2-ethoxy-5-oxo-tetrahydro-3-furany1)-9 [[(1-isoquinolyl) carbony1]amino]octahydro-6H-pyridazino [1,2-a][1,2]diazepin-1-carboxamide (anhydrous or hydrated), their preparation process and the pharmaceutical compositions containing them.
