Beta-agonists are used to alleviate the respiratory distress and bronchospasm resulting from the cholinergic medications used to treat MG.
Albuterol (Proventil-HFA, Ventolin-HFA, ProAir-HFA)
Standard unit doses of beta-agonist nebulizer treatment may improve respirations in a cholinergic crisis. Continuous beta-agonist nebulizer treatment may be indicated in severe cases. Otherwise, the standard dosing regimen of 2 puffs from a metered dose inhaler or 2.5-5 mg nebulized every 4-6 hours often will suffice in achieving bronchodilation.
