Félix Andrés Cuadrado has been found in the Archive of the Royal Academy of Pharmacy, which says it was established on the 5th of the Santa Isabel street, as a collegiate member, on January 2, 1836. It is one of the oldest known, and was located where the Ophthalmic was, until it was transferred to General Arrando, and therefore a good sales area, at least when it was he installed the first of his pharmacists, a native of Arévalo. It is located in the Musas neighborhood, next to establishments such as La Fontana de Oro, Lhardy, the English Brewery or the Canosa Brewery, all of which were daily meeting places from the late 19th and early 20th centuries
