Pulmonary Delivery of Pharmacotherapeutics: A Non-Invasive Promising Approach

Drug delivery strategies become scientific temperament during present day research arena. Pharmacotherapeutics can be successfully delivered through pulmonary route and this approach has captivated excellent scientific and biomedical attention in recent years. This approach has shown substantial progress within the context of local treatment for respiratory disorders, due to the augmented local targeting and decreased systemic side effects with comparatively lesser dose and rapid onset of action [1-4] Furthermore, due to the enormous surface area and high permeation capability of the lung encouraged the scientific community to develop inhalable drug delivery devices. But the respiratory tract tends to be considered as very promising route for the delivery of pharmacotherapeutics in the treatment of local pulmonary diseases such as asthma, chronic obstructive pulmonary diseases, microbial infections as well as systemic diseases such as diabetes, angina pectoris, cancer, bone disorders, tuberculosis, migraine, acute lung injury and others [5-8].
