II. Pharmacology

  1. Hypersensitivity to Sulfonamide groups most affects Sulfonylarylamines, but can affect Non-Sulfonylarylamines and Sulfonamide Moieties
  2. Sulfonamide Allergy does not cross react with sulfur, sulfate, Sulfites

III. Preparations: Sulfonylarylamines (Sulfa agents)

  1. General
    1. Typical sulfa-allergens, with greatest cross-reactivity to other sulfa agents
  2. Sulfa Antibiotics
    1. Trimethoprim-Sulfamethoxazole (Bactrim, Sulfatrim, Co-trimoxazole, Septra)
    2. Sulfadiazine
    3. Sulfacetamide
  3. Sulfa Antiinflammatories
    1. Sulfasalazine
  4. Protease Inhibitors (HIV Infection)
    1. Darunavir (Prezista)
    2. Fosamprenavir (Lexiva)

IV. Preparations: Non-Sulfonylarylamines

  1. General
    1. Similar structure to Sulfonylarylamines , but Hypersensitivity cross-reactivity is uncommon
    2. However, do not use non-Sulfonylarylamines if history of Anaphylaxis or Erythema Multiforme Major to sulfa agents
  2. Diuretics
    1. All Thiazide Diuretics
    2. Some Loop Diuretics (Furosemide, Torsemide, Bumetanide)
  3. Anti-hyperglycemics (Diabetes Mellitus)
    1. Sulfonylureas (e.g. Glipizide)
  4. Analgesics
    1. Celecoxib (Celebrex)

V. Preparations: Sulfonamide Moieties

  1. General
    1. Differ significantly from Sulfonylarylamines (despite both having Sulfonamide group)
    2. However, do not use non-Sulfonylarylamines if history of Anaphylaxis or Erythema Multiforme Major to sulfa agents
  2. Neurologic agents
    1. Sumatriptan (Imitrex)
    2. Topiramate (Topamax)
    3. Zonisamide (Zonagran)
  3. Protease Inhibitor (Hepatitis C Infection)
    1. Simeprevir (Olysio)
