CALOX is a pioneer company in the manufacture and commercialization of high quality generic drugs, committed to health, quality of life and well-being, both human and veterinary.

The company began in 1935 when it began operations under the name Biogen Laboratories. In 1965 CALOX is associated with McKesson, a well-known North American corporation, with a long tradition in the field of medicine since 1833. Through this alliance, CALOX considerably strengthened its technological capacity and marketing activity.

In 1990, CALOX became a 100% Venezuelan company, establishing in 1996 a strategic alliance with Sukia Farmaceutica, a Costa Rican company with 50 years of experience in its market. Today, CALOX owns 2 manufacturing plants: one in Venezuela and the other in Costa Rica, supplying directly to Venezuela, Costa Rica, Panama, Nicaragua, Honduras, Guatemala, El Salvador and the Dominican Republic and, indirectly through maquilas, to commercial partners in Venezuela and the rest of Central America and the Caribbean.
