Abstract

In a pilot study 8 patients with allergic obstructive airway disease were treated with the new compound picumast dihydrochloride (3,4-dimethyl-7-[4-(4-chlorobenzyl)piperazine-1-yl]propoxycoumarine++ + dihydrochloride) 2 x 2 mg daily orally during a period of 8 days additionally to a usual therapy of bronchodilators and corticoids in a steady state. It was demonstrated that the compound inhibited the allergen induced histamine liberation of patients basophils significantly. Compared with a collective of patients without an additional picumast dihydrochloride treatment the effect of the substance was shown more clearly. From reasons of these experimental data picumast dihydrochloride may be of a considerable value as a prophylactic agent in allergic bronchial asthma when given orally.

Basophils

Basophils are myeloid cells with a high affinity IgE receptor and is involved in inflammatory responses during allergy. Discover the latest research on Basophils here.

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.

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.
