Chronic respiratory conditions like asthma have a significant negative impact on world health and need for further study into safe and efficient treatments. The goal of this study is to develop and assess oral herbal granules of Adhatoda vasica Nees, a plant used in asthma treatment because of its bronchodilator and anti-inflammatory qualities. The herbal granules stability, bioavailability, and palatability are all optimized during the formulation process by carefully choosing the excipients. To find the best treatment, the granules contained various doses of Vasaca extract. To assess the products quality attributes, physicochemical characterization is carried out, which involves measuring the products moisture content, flow characteristics, and particle size. Studies on in vitro dissolution are carried out to assess the bioactive compounds release profile and to learn more about the pharmacokinetic behaviour of the goods. In order to ascertain the granules shelf life under various circumstances, stability testing is also conducted.
