The Centers for Disease Control reports that in the U.S. about one in 12 people have asthma.  The numbers are increasing. Between 2001 and 2011, the number of people diagnosed with asthma increased 28%, according to the CDC.(1)  Why the increase? The American Academy of Allergy, Asthma & Immunology lists a few possible theories.

The “hygiene hypothesis” theory suggests that the over-sanitization of a child’s environment can lead to a less robust immune system. Increased antibiotic use parallels the rise in allergy and asthma, leading researchers to theorize the antibiotic use may change the bacterial flora, affecting the immune system. Increased obesity seen in the U.S. can be a contributing factor for asthma.(2)

According to the Asthma and Allergy Foundation of America, common symptoms of asthma include: coughing, wheezing, shortness of breath, rapid breathing, and chest tightening. The foundation states that the first steps towards diagnosis include a doctor discussing the patient’s medical history, a physical exam, and possibly a chest or sinus X-ray. For some patients, a lung function test may be required.(3)

For providers and hospitals, Edge Pharma offers a compounded Methacholine Challenge Kit comprising a set of five pre-filled syringes.
