AKL1 is a novel pharmaceutical agent derived from a combination of botanical products developed as a treatment for obstructive lung disease (asthma and COPD). The botanical product contains a synthetically-derived phytochemical component of Picrorrhiza kurroa, apocynin, together with standardized extracts of Picrorrhiza kurroa, Zingiber officinale and Ginkgo biloba that have previously been marketed as a health food supplements. Recent evidence suggests that Ginkgo biloba reduces inflammatory (protein kinase C positive ie eosinophils and neutrophils) cells in induced sputum which given in addition to inhaled corticosteroids to asthmatic patients. Anecdotal clinical evidence suggests that the botanical product has significant activity in respiratory conditions, with patients diagnosed as having obstructive lung disease (asthma and COPD) reporting reduced symptoms including breathlessness and cough, reduced frequency of attacks, reduced dependence on bronchodilators and ability to reduce inhaled corticosteroids dose.
