Official title
β2AR Polymorphisms and Albuterol Responsiveness in Acute Asthma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The hypothesis to be tested is that acutely ill asthmatics who do not resolve their attacks following standard doses of albuterol and require admission to hospital have single nucleotide polymorphisms of their B2 adrenergic receptors that lower B2 agonist responsivity.
