Cloxacin Dry Suspension is a compounded ingredient that contains Cefaclor, which is an antibiotic that is a second generation cephalosporin, so the compounded formulation can also be considered as an antibiotic that has the ability to kill bacteria. The drug is made up of two ingredients, Cefaclor is mainly more effective against bacterial infections, especially against positive bacterial infections, and respiratory infections are more often positive bacterial infections, so it is mainly used for respiratory infections. Cloxacin dry suspension also includes bromhexine, whose main function is to dilute the sputum, making the sticky sputum more dilute and favoring the expulsion of sputum. Therefore, given the antibacterial spectrum of cefaclor and the main effect of bromhexine, the compound preparation is mainly suitable for respiratory tract infections, on the one hand, it has the function of killing bacteria, killing pathogens and clearing pathogenic bacteria, on the other hand, it can also improve the viscous sputum from the symptoms and promote the discharge of sputum, which is conducive to the treatment of respiratory tract infections. Therefore, although Cloxacin dry suspension is an antibiotic, but in addition to antibacterial effect, it also has the effect of promoting phlegm expulsion.
