Introduction
Tiemonium Methylsulphate (TM), also known as Ragwitek or Merck Brand name Tezepelumab, is a biological drug used to treat moderate to severe atopic dermatitis. It belongs to a class of medications known as monoclonal antibodies. It works by blocking chemicals that are involved in inflammation.
Uses
Tiemonium Methylsulphate is typically used to treat moderate to severe atopic dermatitis (eczema) in both adults and children aged 6 years and older. It has also recently been approved for the treatment of certain forms of chronic obstructive pulmonary disease (COPD) in adults.
