The subcutaneously injected interleukin-13 (IL-13) antagonist tralokinumab-ldrm (Adbry – Leo) and the oral Janus kinase (JAK) inhibitors abrocitinib (Cibinqo – Pfizer) and upadacitinib (Rinvoq – Abbvie) have been approved by the FDA for treatment of moderate to severe atopic dermatitis.

The FDA has approved a 1.5% topical cream formulation of the Janus kinase (JAK) inhibitor ruxolitinib (Opzelura – Incyte) for short-term, non-continuous chronic treatment of mild to moderate atopic dermatitis (AD) in non-immunocompromised patients ≥12 years old whose disease has not been adequately controlled with other topical prescription drugs. Ruxolitinib is the first JAK inhibitor to be approved for topical use and the first to be approved in the US for treatment of AD. An oral formulation of ruxolitinib (Jakafi) is approved for treatment of myelofibrosis, polycythemia vera, and graft-versus-host disease.

Atopic dermatitis (AD; also known as eczema) is frequently associated with other atopic disorders such as allergic rhinitis, asthma, and food allergy. It commonly presents in infancy and early childhood and has a relapsing course, often improving by adolescence, but sometimes persisting into (or first appearing in) adulthood or even old age.

Allergic rhinitis can be classified as seasonal, perennial, or episodic. It is often associated with allergic conjunctivitis, rhinosinusitis, and asthma.

H₁-ANTIHISTAMINES — Oral – Oral second-generation H₁-antihistamines are the preferred first-line treatment for relief of the itching, sneezing, and rhinorrhea that characterize mild-to-moderate allergic rhinitis. They are less effective for nasal congestion.

The FDA has approved dupilumab (Dupixent – Sanofi/Regeneron), a subcutaneously-injected fully human monoclonal antibody, for treatment of adults with moderate to severe atopic dermatitis (eczema) that has not responded to topical therapies. It can be used with or without topical corticosteroids.

The FDA has approved crisaborole 2% ointment (Eucrisa – Pfizer) for topical treatment of mild to moderate atopic dermatitis in patients ≥2 years old. It is the first phosphodiesterase type-4 (PDE4) inhibitor to be approved in the US for this indication.

The FDA has approved the over-the-counter (OTC) sale of Nasacort Allergy 24HR (Sanofi), a triamcinolone acetonide nasal spray previously available only by prescription as Nasacort AQ. The OTC product, which is scheduled to be marketed in the spring of 2014, will be the first corticosteroid nasal spray that can be purchased without a prescription in the US. Nasacort Allergy 24HR is approved for use in patients ≥2 years old with nasal allergy symptoms.

The use of drugs to prevent and control symptoms of allergic disorders can be optimized when patients avoid exposure to specific allergens and/or environmental conditions that trigger or worsen their symptoms.

Allergic rhinitis, allergic conjunctivitis, atopic dermatitis, urticaria, anaphylaxis and asthma (not included here; reviewed in Treatment Guidelines 2008; 6:83) are prevalent worldwide, especially in industrialized countries. Pharmacologic treatment of these disorders continues to improve in efficacy and safety. In addition to using drugs to prevent and control these allergic diseases, patients should be instructed to avoid, if possible, specific allergens and/or environmental conditions that trigger or worsen their symptoms. Allergen-specific immunotherapy may be useful for treatment of allergic rhinitis and allergic conjunctivitis, and in preventing severe insect venom-triggered reactions.

Allergic rhinitis, allergic conjunctivitis, atopic dermatitis, urticaria, anaphylaxis and asthma (reviewed in Treatment Guidelines 2005; 3:33 and not included here), are prevalent worldwide, especially in industrialized countries. Pharmacologic treatment of these disorders continues to improve in efficacy and safety. In addition to using drugs to prevent and control the symptoms of their allergic diseases, patients should also be instructed to avoid, if possible, specific allergens and/or environmental conditions that trigger or worsen their symptoms.

Allergic rhinitis, allergic conjunctivitis, atopic dermatitis, urticaria and anaphylaxis, along with asthma (reviewed in Treatment Guidelines 2002; 1:7 and not included here), have increased in prevalence during the past 30 years and are now epidemic worldwide, especially in industrialized countries. Many safe and effective drugs are currently available for prevention and relief of symptoms in these disorders, but pharmacological treatment alone may not be sufficient. Patients should also be instructed to avoid specific allergens or environmental conditions that trigger their symptoms. Allergen-specific immunotherapy, parenteral administration of gradually increasing doses of the allergen ("allergy shots"), has been effective in allergic rhinitis, allergic conjunctivitis and allergic asthma, and also in prevention of anaphylaxis triggered by stings from bees, yellow jackets, hornets and wasps. It has not been effective in food allergy, atopic dermatitis or urticaria.
