Introducing TopChem Pharma

TopChem Pharmaceuticals Limited was established in 2006 as a new GMP supplier of APIs and related support services to the Pharmaceuticals sector worldwide. TopChem is targeting niche, low-volume APIs and excipients that are often difficult to source by Drug Product companies.

Our Products page shows the range of products we have developed. Please contact us if you have an API or Excipient that you cannot find. Most of our products have been developed in response to specific customer demand. We can offer global or territory exclusivity if required.

TopChem Pharma has successfully passed GMP inspections by the US FDA and EU regulatory authorities. All our products are manufactured in our GMP facility in Sligo, Ireland.

TopChem operates to the highest international Quality, Safety and Environmental standards.
