Inflammatory myositis typically follows a step-wise treatment approach based on disease severity and progression. For mild cases at onset, prescribers commonly rely on corticosteroids such as prednisone for its potent anti-inflammatory effects. If symptoms persist, a steroid-sparing immunosuppressant such as methotrexate (Rheumatrex) may be added.

For moderate-severe disease, prescribers often initiate combination therapy with glucocorticoids and immunosuppressants. Popular choices include prednisone with methotrexate, mycophenolate mofetil (CellCept), or azathioprine (Imuran). Intravenous immunoglobulin (Gamunex, Privigen) provides an alternative first-line approach.

In refractory cases, biologics that target specific immune processes become options. The tumor necrosis factor inhibitors infliximab (Remicade) and adalimumab (Humira) see frequent usage. The interleukin-6 receptor blocker tocilizumab (Actemra) also demonstrates effectiveness. Off-label drugs like rituximab (Rituxan) may feature when other treatments fail.

Other factors influencing prescriber preferences include cost, insurance coverage, safety/tolerability, convenience of oral versus intravenous dosing, and past patient responses. Monitoring disease progression through physician-patient communication and biomarkers aids treatment selection.

Inflammatory myositis can be broadly classified into three stages - mild, moderate, and severe based on symptoms and muscle involvement.

In the mild stage, medications like hydroxychloroquine and methotrexate are preferred as first-line treatment options either alone or in combination. These slow the disease progression with minimal side effects.

The disease progresses to the moderate stage with increasing muscle weakness. At this stage, immunosuppressants like mycophenolate mofetil are widely used either alone or in combination with glucocorticoids. Mycophenolate is very effective in reducing disease activity and preventing relapses with a mild side effect profile.

In refractory or severe cases, biologics may be considered. Inambiix (sarilumab) - an interleukin-6 receptor antagonist, is becoming the standard of care owing to its effectiveness in improving muscle strength and inhibiting further damage. It is usually used along with low-dose glucocorticoids to boost response rates. Actemra (tocilizumab) is another biologic from the same drug class as Inambiix and used interchangeably depending on insurance and cost considerations.

Stem cell transplantation using the patient's own hematopoietic stem cells (autologous HSCT) is sometimes considered for aggressive cases unresponsive to other therapies to induce remission. However, it is a high-risk procedure reserved only for select refractory patients due the risk of life-threatening complications.
