Study summary

Considering the pathogenesis of several allergic skin diseases to be investigated in this study as well as the pharmacodynamic mechanisms of the association of dexamethasone and clemastine fumarate, it is believed that the components of topical medication may act synergistically in the reduction of signs and symptoms of the diseases in question. Therefore it is expected that the association promotes results significantly superior to dexamethasone alone.

What researchers measure

Primary outcomes

  1. Through clinical examinations, evaluating the efficacy of the cream composed by 0.5 mg dexamethasone and clemastine 1mg compared with the cream of 0.5 mg dexamethasone in improving the signs and symptoms associated with allergic dermatitis.

    Time frame: 14 days

Secondary outcomes

  1. Improvement of the erythema associated with allergic dermatitis.

    Time frame: 14 days

  2. Improvement of the edema associated with allergic dermatitis.

    Time frame: 14 days

  3. Improvement of the extension of lesion associated with allergic dermatitis.

    Time frame: 14 days

  4. Evaluate, through clinical examinations, the effectiveness of the drug association in reducing excoriation associated with allergic dermatitis.

    Time frame: 14 days

  5. Evaluate, through clinical examinations, the effectiveness of the drug association in reducing exudation associated with allergic dermatitis.

    Time frame: 14 dyas

  6. Evaluate, through clinical examinations, the effectiveness of the drug association in reducing of scabbing associated with allergic dermatitis.

    Time frame: 14 days

  7. Evaluate, through clinical examinations, the effectiveness of the drug association in reducing of lichenification associated with allergic dermatitis.

    Time frame: 14 days

  8. Evaluate the safety of the formulations in relation to the occurrence, type, frequency and intensity of adverse events during treatment.

    Time frame: 14 days
