Imprimis Pharmaceuticals Reports Results of Independent Third Party Potency Analysis of its Compounded Pyrimethamine and Leucovorin Capsules

SAN DIEGO, Dec. 11, 2015 /PRNewswire/ -- Imprimis Pharmaceuticals, Inc. (NASDAQ: IMMY), a specialty pharmaceutical company focused on the development and commercialization of proprietary compounded drug therapies, today released the results of a third party potency analysis of its customizable compounded formulation of pyrimethamine and leucovorin for physicians to consider prescribing as a lower cost alternative to Daraprim® for toxoplasmosis and other types of infections.  An independent third party laboratory tested the potency of the active pharmaceutical ingredients (API) of its pyrimethamine and leucovorin formulation using U.S. Pharmacopeia (USP) methods described in the monograph for each API.  The USP standard, recognized by the FDA, is used in the U.S. and internationally in order to set the standards for the identity, strength, purity and other important qualities of active drug ingredients.  The subject report on assays from a random sampling of Imprimis' pyrimethamine and leucovorin capsules found that the concentration of purported 12.5 mg of pyrimethamine was 100.1% potency with 12.509 mg of the active drug found, and the purported 2.5 mg of leucovorin tested had 100.5% potency with a concentration of 2.512 mg of active drug found.  The sample met USP potency requirements. 

Upon a physician prescription for a patient's specific condition, Imprimis will customize various quantities and dosages of its pyrimethamine and leucovorin formulation, making this formulation available as a personalized medicine, and the cost will remain $0.99 per capsule.  If you would like to learn more about this formulation, or if you are a physician and would like to order it, please visit

Mark L. Baum, CEO of Imprimis stated, "As a part of the process of familiarizing our newest customers with the value we are presenting to the market with one of our oral dosage formulations of pyrimethamine and leucovorin, I am happy to make public, independent potency testing results of a random sampling of this formulation.  These excellent results speak to the quality of our process, the skill of our team and the value we bring in our service of patients."

Baum continued, "I am confident, that as a national leader in pharmaceutical compounding, our commitment to quality, for sterile and non-sterile dosage forms, is second to none.  All raw materials we use are made at FDA-registered and inspected manufacturing facilities that must comply with current good manufacturing practices (cGMP).  We only purchase active drug ingredients that have the USP monograph claim.  All of our FDA approved raw materials come with certificates of analysis connected to the USP monograph.  Federal and state oversight is a part of every aspect of our drug supply chain from raw material acquisition to production, testing and dispensing.  We meet and/or exceed all quality standards for the formulations we dispense and we are committed to transparency to our customers when it comes to the batch and lot testing we do, including providing the actual sterility test results for each order we dispense for a sterile compounded drug."

Imprimis' finished compounded drug formulations do not have an FDA-approval label for recommended use.  Imprimis finished compounded formulations are not FDA approved and may only be prescribed pursuant to a physician prescription for an individually identified patient consistent with federal and state laws governing compounded drug formulations.
