Introduction

Myasthenia gravis is a chronic autoimmune neuromuscular disorder characterized by antibody-mediated disruption of neuromuscular transmission, leading to fluctuating muscle weakness and fatigue. Traditional treatment approaches relied on acetylcholinesterase inhibitors, corticosteroids, and broad immunosuppressants, but modern care increasingly incorporates targeted immune therapies. These advanced drugs focus on complement pathways, Fc receptor mechanisms, and B-cell mediated immune responses.

In Americas, treatment strategies are evolving toward precision immunotherapy supported by antibody profiling and disease severity classification. Advances in neuromuscular diagnostics and immune pathway research are improving therapy targeting. The therapeutic landscape is shifting toward mechanism-specific and steroid-sparing regimens.
