Dr. Karl Thomas

Dr. Karl Thomas GmbH was a significant German pharmaceutical company based in Biberach an der Riß, which operated as a major subsidiary of Boehringer Ingelheim. The company is historically notable for the discovery and development of several essential medicines, most notably the antiplatelet drug dipyridamole (Persantin) and the respiratory treatments bromhexine (Bisolvon) and ambroxol (Mucosolvan). Following its full integration into the Boehringer Ingelheim group, its Biberach site has evolved into one of Europe's largest centers for biopharmaceutical development and production. Today, the legacy of Dr. Karl Thomas persists through these widely used therapeutic products and the continued industrial importance of its original headquarters. The company played a pivotal role in establishing Biberach as a global hub for pharmaceutical research and manufacturing.
