From Bayer Schering Pharma AG:
Echovist-200® was an effectively one-pass-only contrast medium for contrast sonography and Doppler-echocardiographic examinations for the detection, exclusion or follow-up of pathological states leading to hemodynamic changes. Because of the short intravascular life of the microparticles and microbubbles, transit through the pulmonary circulation is unusual. In cardiac evaluations Echovist-200® has been replaced by newer ultrasound contrast agents (USCA), therefore the manufacturing was discontinued.
Another range of echo contrast application is the female genital tract, in particular for the demonstration or exclusion of acquired or congenital changes of the uterine cavity and for the visualization of the Fallopian tubes and investigation of their patency.
1 g Echovist-200 granules contain 1 g D-galactose microparticles. 1 ml aqueous solution for production of the suspension contains 200 mg D-galactose.
Brand names in other countries: Ecovist.

The Germany-based pharmaceutical company is the result of the take-over of Schering AG by Bayer AG in 2006. The Bayer Schering Pharma AG is part of the Bayer HealthCare AG, which represents the pharmaceutical part of the Bayer Group.
