Pulmonary drug delivery systems have proven to be advantageous due to high drug-loading efficiency and effective absorbance

Pulmonary drug delivery systems have helped many patients on their way to recovery. In fact, PDR is one of the most commonly used choices in the treatment of pulmonary embolism, a type of blockage in the pulmonary circulation that causes blood to pool in the lungs. This condition, if left untreated, could cause partial or full restriction of blood supply to the patient, or even death. A PDR will help a patient safely and comfortably get these medications into their system.

The concept of a PDR came about when a nurse was assigned to a patient who was in the process of being given IV drugs. The nurse noticed that the patient was often not able to follow the oral instructions for the medications. This nurse was able to alter the oral syrups to help the patient complete the doses and to avoid some of the problems that he was having. This led to the development of this convenient and easy-to-use system for administering medications. Now, the same technology has been adapted for the pumping of medications into the lungs of patients.

There are several different types of pulmonary drug delivery systems that can be used depending on the severity of a patient's condition. The actual system has been designed to fit into a vein and to be attached to the lung tissue with a number of pumps. The system delivers the medications into the bloodstream through the vein and into the lungs. There are ventilators that are included in some systems in order to improve the oxygenation of the lungs during the process of delivery. Pulmonary drug delivery systems have been designed to fit easily into a medical office or surgical suite, and are used in the best possible manner for all patients. PDRs are available in two primary forms. There are the systems that are used directly by the physicians themselves. These are called the "direct ventilating units" and the "self-contained ventilating system." Both of these types of PDRs have been very successful in delivering important and lifesaving drugs directly to the lungs of patients who need them. It is even possible for patients to receive a dose of a PDR via a mobile air transfer unit.
