Liposomes and Nanotechnology in Drug Development: Focus On Pancreatic Cancer

Abstract

Pancreatic cancer usually has high morbidity and mortality and rests one of the most challenging cancers to treat. 5 years survival rate is less than 6 percent overall for people with pancreatic cancer, because of very late diagnosis and absence of effective treatment. In a western world, pancreatic tumor is the fourth most common cause of death in a western world. The pancreatic tumor needs selective delivery of drugs to target cells, with no side effects is major goals of the recent investigations for the real treatment of the pancreatic tumor. Medication which targets pancreatic tumor cells specially and carriers which deliver medications to specific cells which are quickly dividing, development of these kind drugs is considered as magic for the management of pancreatic cancer. In latest years, liposomes and nanotechnology can show a vital character in the treatment of pancreatic tumor. Liposomes contain multiple characteristics, such as the ability to protect the material from degradation, the capacity for encapsulating many materials and capability for delivering materials intracellularly fusion with plasma membrane. Nanoparticles as a carrier offer a new style of delivery of the medications to target cells of a tumor and allow drugs for the binding to tumor cell membrane, to cytoplasmic and to nuclear receptor sites. It delivers high medication concentrations to specific cells with few side effects to other normal tissues. The general importance of this evaluation is to increase overall understanding of development of the therapeutic nanomedicine for the treatment of pancreatic tumors, agents delivered by nano-liposomes, liposomal nanomedicine in targeting cancer and safety issues.
