Company Develops Universal Dose Counter For Asthma Inhalers

Attention: Business/Financial Editor, Health/Medical Editor, Lifestyle Editor, Science Editor, Tech/Telecomm Editor HARROW, ONTARIO --(Marketwire - Oct. 8, 2009) - Ontario based Eristan Medical Systems has developed and successfully tested a universal dose counter for metered dose inhalers. PulmoScale? utilizes the weight of an inhaler's contents to accurately determine the number of doses remaining. Their latest model can be used with every inhaler available in Canada. In 2003 the FDA challenged manufacturers to develop counting systems for their inhalers so that users could keep better track of their medications and avoid needless trips to the emergency room. Six years later, less than 25% of inhalers are available with counters.

"We are extremely pleased to have developed a cost effective product that can address the needs of all Asthmatics," stated Stan Langford, President of Eristan. Before PulmoScale? the only way most Asthmatics could be sure they had medication left in their inhaler was by manually logging each actuation; an inconvenient and time consuming task prone to mistakes.

Inhalers have a long history as being the most reliable method of delivering aerosol medications to the lungs. Their major shortcoming has been the inability to keep track of how many doses have been used. Consequently, many patients use them long beyond their useful life. Drug manufacturers caution us, that if an inhaler says 200 doses, then you get only 200 reliable doses. An inhaler will release propellant for another 60 to 80 puffs, but that gas may not contain enough active medicine to stop an attack. Unlike a certain brand of coffee, your asthma puffer is not "good 'til the last drop."
