Pancreatic cancer (PC) is the fourth leading cause of deaths in the United States, claiming approximately 43,000 lives every year. Existing trends suggest that it will be the second cause of death after lung cancer within the next 20 years. With mortality rates remaining high even after decades of research, scientists are now turning to develop chemopreventive strategies that may stop or delay the initiation and progression of the disease. Our study reports the chemoprevention potential of (1) a free drug combination of H1-receptor antagonist drug with Sulforaphane (SFN), a neutraceutical compound derived from broccoli and (2) lipid nanocarriers of H1-receptor antagonist drug (SP1 SMEDDS; formulation patent pending) with free SFN when administered at low doses in human pancreatic cancer cell lines (MIA PaCa-2 and Panc-1). IC50 concentrations were calculated for various treatment groups using MTS viability assay in accordance with published protocol, using 96-well microplates and incubation time of 72 h. The free drug combination revealed almost 70-fold and 20-fold enhancement in chemoprevention efficacy (based decrease in cancer cell viability) as compared to controls. Interestingly, the free drug combination (at 5µM) showed ~55 % (p Citation Format: Preshita Desai, Arvind Thakkar, Jeffrey Wang, Sunil Prabhu.
