“…Thus, it is very crucial for an effective drug delivery system to deliver the therapeutic moiety to the target site at the right time and in an appropriate amount especially with various chronic respiratory diseases, such as asthma where an immediate therapeutic action is needed. Most of the conventional dosage forms have various limitations such as dose dumping, non-targeted effects, multiple administration of drug leading to lesser patient compliance, which lead to the emergence and trends of novel drug delivery systems where nanotechnology is one of the key role players [ 3 ]. Nanotechnology is an area in which the drug is incorporated into a nanosystem that provides a new dimension to the pharmacotherapy and have cell-targeted drug delivery approach [ 4, 5 ], which is required in majority of the chronic respiratory conditions such as lung cancer, COPD, and pulmonary fibrosis.…”
