  3. Methodology

    DMARDs is not very well defined term but we selected the basket of medicines below to include based on clinical experience and NHS polices such as the North Central London Joint Formulary Commmittee DMARDs quick reference guide for primary care prescribers. We used BNF code hierachy to generate a list of dm+d AMPS and VMPs.

    Medicines included

    • Azathioprine
    • Mercaptopurine
    • Sulfasalazine
    • Hydroxychloroquine
    • Ciclosporin
    • Methotrexate
    • Penicillamine
