Faes Farma Zyloric (Allopurinol)

Zyloric is a widely used brand name for the medication allopurinol, primarily prescribed to treat hyperuricemia and prevent gout attacks. In Spain, this product is commercialized and manufactured by Faes Farma, S.A., a Spanish pharmaceutical corporation founded in 1933 in Bilbao (Basque Country).

Faes Farma operates extensive research, development, and manufacturing facilities in Spain, notably in Leioa (Bizkaia) and Derio. While the allopurinol molecule and original brand names were developed historically by international predecessors (such as Burroughs Wellcome), the marketing and supply rights in Spain reside with Faes Farma, an independent publicly traded company listed on the Spanish stock exchange (Bolsas y Mercados Españoles).
