Nebulization of pharmacological solutions with an innovative medical device based on microvaporization
2023
The currently available nebulization devices have a slow aerosol flow and produce vapor with large microdrops. Improved devices that achieve higher airflow and produce smaller microdrops are needed to improve the clinical care of patients. To address this critical need, we developed a novel system for the molecular vaporization of liquids. This device vaporizes an active pharma-cological substance dissolved in water, alcohol, or a mixture of water and alcohol using two energy sources at the same time: high-frequency ultrasound and thermal induction. Application of energy to a solution contained in the device's tank allows, within tens of seconds, for the vaporization of the solution itself,…
Pharmaceutical compositions in the form of gel containing xyloglucan and alcohols for the controlled release of active ingredients
2020
The invention relates to gel compositions comprising pharmaceutical active ingredients. The composition comprises xyloglucan at concentration between 0.1% and 10.0% by total weight of the composition, together with a primary alcohol at a concentration between 20.0 and 50.0% by total weight of the composition. The invention also describes a process for the preparation of the composition and its use in the treatment of pathologies wherein a controlled release of the active principle is useful.
