Efficacy of Albuterol in the Treatment of Congenital Myasthenic Syndromes

The aim of the proposal is to evaluate the effects of albuterol, an adrenergic agonist, in the treatment of congenital myasthenic syndromes (CMS). Over the past 2 decades I found that some CMS patients refractory to or worsened by cholinergic agonists, namely those suffering from defects in acetylcholinesterase (AChE) or Dok-7, respond to ephedrine, a medication used for over half-a-century in the treatment of autoimmune myasthenia gravis. After ephedrine became unavailable, I treated the same type of patients with albuterol in doses ranging from 4 mg daily to twice daily for adults; the dose for children 6 to 12 years is 2 mg two or three times daily; the dose for children 2 to 6 years is 0.1 mg/kg/day (maximum 2 mg) three times daily. Evaluation of the effects of the medications are based on the Table shown below.
