Routes Of Drug Delivery To The Lungs Pdf Respiratory Tract Lung

Routes Of Drug Delivery To The Lungs Pdf Respiratory Tract Lung Abstract. pulmonary drug delivery offers targeted therapy for the treatment of respiratory diseases such as asthma, lung cancer, and chronic obstructive pulmonary diseases. however, this route poses challenges like deposition mechanism, drug instability, and rapid clearance mechanism. other factors like the type of inhaler device, patient. Pulmonary drug delivery is a highly attractive topic for the treatment of infectious lung diseases. drug delivery via the pulmonary route offers unique advantages of no first pass effect and high bioavailability, which provides an important means to deliver therapeutics directly to lung lesions. starting from the structural characteristics of the lungs and the biological barriers for achieving.

Inhaled drug delivery has been an emerging route for the treatment of lung diseases with clear advantages over oral and intravenous routes. however, the delivery efficacy is affected by multiple physiologic barriers including mechanical clearance, mucociliary clearance, macrophage phagocytosis and exhalation lymphatic transport in the respiratory tract. The respiratory membrane is highly permeable with sufficient blood flow in the lungs, which can avoid the first pass effect following systemic administration. thus, pulmonary drug delivery represents a promising route of drug administration especially for therapeutic drugs that easily undergo liver metabolism following the first pass effect. Pulmonary drug delivery is relatively complex because the respiratory tract has evolved defense mechanisms to keep inhaled drug particles out of the lungs and to remove or inactivate them once deposited. in addition to these mechanical, chemical and immunological barriers, pulmonary drug delivery is adversely affected by the behavioral barriers.

Pulmonary drug delivery is relatively complex because the respiratory tract has evolved defense mechanisms to keep inhaled drug particles out of the lungs and to remove or inactivate them once deposited. in addition to these mechanical, chemical and immunological barriers, pulmonary drug delivery is adversely affected by the behavioral barriers. Inhalation drug delivery, compared with other routes, is a promising non invasive strategy and may be the most appropriate treatment for patients suffering from lung disorders. the market appeal for inhaled medications to treat lung disorders could confirm these advantages. inhalation drug delivery to the lungs would provide rapid. To provide drug delivery devices that are efficient for delivery of drugs to the respiratory tract and convenient to use for patients, different pulmonary devices have been designed and developed. the most commonly used inhaler devices are classified into three groups: nebulizers, pressurized metered dose inhalers (pmdis), and dry powder.
