The excretions of the coordination compound of germanium with nicotinamide (MIGU-2) was studied. After single-valued intraperitoneal introduction the compound was excreted mainly by urine. 74.98 % of germanium from introduced dose was excreted during 48 hours, out of 53.01 % by urine and 21.97 % by faces. Germanium was determinated in the faces only during 48 h. 85.00 % of introduced dose was excreted during 120 h, out of 63.03 % by urine and 21.97 % by faces. Studies did not determinate organs and tissues, which accumulated germanium.
