RECENT APPLICATIONS AND POTENTIALLY ADMINISTER FUTURE PHARMACO THERAPY OF PULMONARY DRUG DELIVERY SYSTEM M. Navya*, Kameswara Rao. S

Abstract: Pulmonary route as an non-invasive administration for systemic delivery of therapeutic agents (mainly peptides and proteins) due to the fact that the lungs could provide a large absorptive surface area but extremely thin (0.1 μm ? 0.2 μm) absorptive mucosal membrane and good blood supply. However, recent advances show great promise, but pulmonary delivery of peptides and proteins is complicated by the complexity of the anatomic structure of the human respiratory system and the effect of disposition exerted by the respiration process. Pulmonary drug delivery system is a needle free technique.. Now a day’s pulmonary drug delivery remains the preferred route for administration of various drugs. It is an important research area which impacts the treatment of illnesses including asthma, chronic obstructive pulmonary disease and various diseases. Drug is delivered directly to the conducting zone of the lungs. In this article, we summarize recent advances in applications of pulmonary drug delivery system. Previously pulmonary drug delivery is used for management of Asthma and COPD only but due advancement in application nowadays Pulmonary drug delivery is useful to treat Diabetes, angina pectoris, cancer , bone disorders ,migraine, tuberculosis, acute lung injury and others.
