Welcome to Sigma Pharmaceuticals Limited


Sigma Pharmaceuticals Limited is a leading Australian manufacturer and marketer of prescription, over-the-counter and generic pharmaceutical products. We are also a leading full-line wholesaler and distributor to pharmacies throughout Australia.

Our success is supported by our ownership of some of the largest and most recognised pharmacy retail brands in Australia, Amcal and Guardian and the Amcal Max brand, as well as the special relationship we have with our banner member and independent pharmacist customers and medical practitioners.

Our ability to grow is enhanced by the group's portfolio of strong brands that are sold across a broader distribution network covering both the pharmacy and grocery channels.

Sigma was originally founded by two Melbourne pharmacists in 1912 and merged with Arrow Pharmaceuticals in December 2005. Following the merger, the business has expanded to provide a comprehensive service and product offering to our customers.
