LIPOSOMAL DRY POWDER INHALER: NOVEL PULMONARY TARGETED DRUG DELIVERY SYSTEM FOR THE TREATMENT OF LUNG CANCER

Abstract

Lung cancer is a great evil doer behind mortality around the world. The degree of lung cancer patients in developing nations has grown from 31% to 49.9% over the recent 20 y. Despite current upgrades in lung cancer chemotherapy, the death rate in lung cancer patients is high. Generally, cancer chemotherapy is accompanied by most side effects. If an anticancer drug could deliver only the right site in the right concentration at the right time, cancer could be cured without side effects. A liposomal dry powder inhaler (LDPI) is an innovative strategy to convey drug particles. A dry powder inhaler (DPI) has unique features such as targeted drug delivery, improved bioavailability, and the better therapeutic efficacy of the embedded drug's ability to deliver the drug at a constant rate. This paper emphasizes the utility of liposomes and DPI in lung cancer therapy, commonly used formulation techniques for manufacturing LDPI, various devices used to deliver the therapeutic formulation, and ongoing and recently concluded clinical trials. Patents filed by multiple researchers and the future perspective of LDPI in an innovative drug delivery system and promising systems for administering a wide variety of drugs, including anti-cancer drugs, are described for lung cancer.
