Problems solved by technology

There is a capsule dosage form of compound omeprazole on the market in foreign countries, the specification of sodium bicarbonate reaches 1.1g / capsule, and the prepared capsules are relatively large, so it is difficult to be suitable for some patients with swallowing disorders and elderly and children patients.
In order to avoid the decomposition and damage of gastric juice, the existing proton pump inhibitors are mostly oral enteric-coated preparations, which need to be coated with enteric coating during production. This design has several disadvantages: ① Special coating equipment is required in the production process , the process requirements are high, which increases the production cost; ②Most enteric-coated preparations are moisture-sensitive; ③Due to the release in the intestinal juice, the onset of the drug slows down and the time to peak is delayed
