Cambridge Consultants and India’s Sun Pharma Advanced Research Company (SPARC) have developed a new dry powder inhaler. According to the companies, the device delivers an even, consistent drug dose deep into the lungs regardless of how strong the inhalation is performed by the patient.
The device employs a novel de-agglomeration engine to separate the drug from the lactose ‘carrier’ particles. Based on a highly efficient airway design, the patented drug separation mechanism has successfully completed clinical trials and demonstrated that it is capable of delivering significantly more of the drug to the deep lung than traditional inhalers. In practice, this will minimise side effects from drug build-up in the back of the throat, reduce non-systemic load and wastage, and means almost 50% less active drug needs pre-loading into the device in comparison to a standard inhaler.
This step change in inhaler technology is a reliable and easy to use device, particularly for patients with impaired lung function or those using the inhaler during an asthma attack – overcoming any patient concerns about the ability to use the device effectively.
In addition to its novel drug delivery mechanism, the device integrates a number of user-friendly design features. These include a numerical dose counter to indicate at a glance how many more doses are left in the inhaler before it runs out, a luminous feature to enable users to find the device in the dark and a small pop-out ‘braille’ button which activates when there are only a few doses remaining. The device gives audible and tactile feedback to indicate the delivery and completion of user steps. The device also features a unique palm-held form, designed to discreetly house the complex dose carriage and delivery system yet remain comfortable to hold and use.
