The effects of long term Tranilast administration on bronchial hypersensitivity in asthmatics

Tranilast is an oral antiallergic agent developed in Japan. This study investigated the effect of prolonged administration of Tranilast on the bronchial sensitivity of 18 asthmatic subjects. They were treated for either less than 3 months or more than 3 months continuously. Methacholine loading testing was used to assess bronchial reactivity, and the respiratory parameters were recorded on an Astograph. Patients treated for longer than 3 months showed a significant decrease in bronchial sensitivity (p less than 0.05). The anticholinergic and bronchodilatory properties of Tranilast were also investigated in 8 subjects. No significant anticholinergic or bronchodilatory effects were observed following a single oral dose of 100 mg of Tranilast.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.


This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
