Problems solved by technology

In these preparations, there are many deficiencies, such as ordinary tablets, capsules, and granules, which are used for a long time for the treatment of patients, and the natural herbal medicine extracts all have the characteristics of slow onset, so It is unfavorable for patients with hemiplegia and elderly patients with coronary heart disease to take medicine too many times a day; in addition, the way of taking medicine three times a day makes the blood drug concentration show a peak-valley effect, which is not conducive to the treatment of diseases; according to the point of view of pharmacoeconomics , one more way of taking medicine will cause huge sunk costs for doctors, nurses and patients, resulting in a huge waste of resources
The existence of safety problems caused by injections due to various factors, chills, arrhythmia, dyspnea and even shock, which have been widely reported, are all great potential unsafe factors
