Benefits of technology

This patented technology solves problems with traditional methods for delivering medicine through skin or mucous membranes by allowing it to slowly dissolve over time without causing any side effects on other parts of our bodies. It achieves these benefits while maintaining stability at physiological levels within an organism's circulatory system.

Problems solved by technology

This patented technical problem addressed in this patents describes how to develop a new combination formulation containing three active ingredients (the first being called pseudoprofen) followed by each component separately chosen based on their desired therapeutic results. Previous methods were either slow down or require complicated steps like extractions before administering them individually. Therefore, these techniques had limitations because they could lead to overuse syndromes related to inflammability and reduced immunity.

Abstract

The invention provides a compound preparation which can comprehensively overcome the symptom relative to cold and can slowly release all the active ingredients. The slow-release preparation of the invention not only can overcome the symptom relative to cold but also can perform the synergistic function of compound medicine. The three active ingredients of the slow-release preparation of the invention can be released and absorbed synchronously so as to acquire expected releasing action in human body. The preparation of the invention can be taken for two times per day, namely, can be taken for one time in morning and evening instead of taking four times per day in the past. The preparation of the invention is characterized by less taking times, slow release in body, stable blood concentration, small fluctuation, high bioavailability and high safety.
