Serving The Underserved…Safely

Our Name & Mission

Primus means "first" in Latin. Primus Pharmaceuticals is the first and only company specializing in prescription medical nutrition.

What Patients Want

Above all, patients want to improve their quality of life. They want products that are clinically proven to be safe and effective and to avoid side effects and adverse interactions commonly associated with other medications. Patients instead want products with pure and natural ingredients that are manufactured to high standards of quality and consistency that help minimize the overall cost of care.
