Callan

Callan Pharma Services is a private, founder-led formulation development company focused on solving complex ophthalmic and parenteral drug delivery challenges for pharmaceutical clients. The company operates as a research laboratory rather than a commercial drug manufacturer, offering formulation development, analytical services, lyophilization support, intellectual property support, and nanoparticle-related capabilities. Its work emphasizes poorly water-soluble drugs and uses its proprietary Apisolex polymer technology to address solubility and pharmacokinetic limitations. Based in Tampa, Florida, Callan appears to function primarily as a specialized CRO and formulation partner rather than a therapeutic product company with a disclosed internal clinical pipeline.
