From the Guidelines

Salbutamol is not a standard treatment for myasthenia gravis, and the primary treatment for this condition is pyridostigmine bromide administered orally two to four times a day. Myasthenia gravis is a chronic autoimmune disorder that affects the neuromuscular junction, leading to muscle weakness and fatigue. The treatment for myasthenia gravis typically involves medications that improve neuromuscular transmission, such as acetylcholinesterase inhibitors like pyridostigmine bromide 1.

Treatment Options

  • Pyridostigmine bromide is the first-line treatment for myasthenia gravis, but about half of patients with strabismus-associated myasthenia show minimal response 1.
  • Corticosteroids are also effective in treating myasthenia gravis, with about 66% to 85% of patients showing a positive response 1.
  • Immunotherapy with azathioprine or other agents may be offered by treating neurologists for some patients 1.
  • Thymectomy is indicated in some cases, always in the presence of thymoma, and may substantially reduce symptoms for certain subpopulations with myasthenia gravis 1.

Salbutamol Use

Salbutamol, also known as albuterol, is a beta-2 adrenergic agonist that is commonly used to treat bronchospasm in conditions such as asthma. While it may be used to treat bronchospasm in patients with myasthenia gravis, it is not a standard treatment for the condition itself 1.

Management

Diagnosis and management of myasthenia gravis require the training and clinical judgment of an experienced ophthalmologist typically working in concert with a treating neurologist 1. Counselling and referral to a neurologist or neuro-ophthalmologist, and sometimes a general surgeon, is often indicated in the management of myasthenia 1. The ophthalmologist should discuss the findings, explain the disorder, provide a diagnosis, and discuss management options with the patient and any caregivers and be aware of any comorbidities such as respiratory distress that might present with generalization of the disease 1.

From the Research

Treatment of Myasthenia Gravis

  • Myasthenia gravis is typically treated with acetylcholinesterase inhibitors, immunosuppressive, and immunomodulatory therapies 2
  • The primary goal of treatment is to improve neuromuscular transmission and reduce the production or presence of the nicotinic acetylcholine receptor (achR) 3
  • Treatment options include:
    • Acetylcholinesterase inhibitors as the first line treatment
    • Plasmapheresis or intravenous immunoglobulin (IVIg) for exacerbations
    • Thymectomy in cases of suspected thymoma or in young patients with unstable myasthenia gravis
    • Corticosteroids and/or immunosuppressive agents for severe forms of the disease

Role of Salbutamol (Albuterol)

  • There is no direct evidence in the provided studies that salbutamol (albuterol) is used to treat myasthenia gravis
  • Salbutamol is a beta-2 adrenergic agonist commonly used to treat asthma and chronic obstructive pulmonary disease (COPD), but its use in myasthenia gravis is not mentioned in the studies 3, 4, 5, 6, 2

Immunomodulatory Therapies

  • Immunomodulatory therapies, such as corticosteroids, azathioprine, mycophenolate mofetil, and cyclosporine, are used to treat myasthenia gravis 4, 5, 6
  • These therapies aim to reduce the immune system's attack on the nicotinic acetylcholine receptor (achR) and improve neuromuscular transmission 3
