Problems solved by technology

[0005] Currently, the dosage forms of azithromycin in clinical use include ordinary tablets, capsules, suspensions, injections, granules, etc. Most of these oral dosage forms need to be taken with water, and it will be difficult for patients with difficulty in swallowing or taking water; although granules The granule is a dosage form specially designed for children, but because most children cannot drink it by themselves, and it is inconvenient to take granules in schools or kindergartens, these dosage forms cannot fully meet the medication needs of all patients
