The original pharmacy was mentioned in the 16th century and was located in five rooms from the second half of the 18th century until its abolition and handover for museum purposes in 1953.

The collection of the Museum has 8,500 items and nearly 3,000 volumes of old pharmaceutical literature, which is rarity in Slovakia. The permanent exhibition of the museum provides access to the history of pharmacy in Bratislava in the first of three rooms. The entrance room is furnished with furniture from the original pharmacy "U červeného raka".
