Problems solved by technology

Ordinary tablets, because ceftazidime pivoxil hydrochloride has a very bitter taste, generally need to be taken after coating the tablet core, the process is complicated, and both of these two dosage forms have the problems of slow dissolution and slow onset of action
Although the suspension is convenient to take, it still needs to be controlled under certain conditions during production and storage.
