Abstract

A double-blind comparison between orally administered NAB 365 (clenbuterol) and salbutamol was conducted in 30 impatients with either asthma or chronic bronchitis with asthma who had at least 15% reversibility in airway obstruction following inhalation of 1,500 microgram of orciprenaline. NAB 365 (clenbuterol) was administered to 15 patients at 30 microgram b.i.d. for 3 days; then the dosage was reduced to 20 microgram b.i.d. Salbutamol was administered to the other 15 patients at 4 mg t.i.d. Both drugs were administered for an average of 13 days. NAB 365 (clenbuterol) was shown to be an effective bronchodilator, with more rapid activity than that of salbutamol, on the FVC, FEV1, PEFR, the differences being significant on the third and seventh day of treatment. These findings are briefly discussed. No significant cardiovascular effects were noted for either drug, nor were differences found in need for additional treatment or in side-effects.

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.

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.
