Roxithromycin Ambroxol Tablets and Amoxicillin can be used together, but they are not normally used that way. Roxithromycin Ambroxol Tablets is a compound preparation, the main ingredients of which are Roxithromycin and Ambroxol Hydrochloride. Roxithromycin mainly acts as a bacteriostatic agent and is used for diseases caused by infections of G+ bacteria, mycoplasma or chlamydia. Ambroxol hydrochloride can promote the secretion of lung surface active substances and airway fluid secretion, promote the dissolution of mucous sputum and facilitate sputum discharge. And amoxicillin is a broad-spectrum penicillin antibiotic with strong bactericidal effect, powerful bacteriostatic and bactericidal effect on most G+ and G- bacteria, but resistant to mycoplasma and other flora. Some studies have shown that macrolide anti-inflammatory drugs such as roxithromycin can interfere with the antimicrobial effect of amoxicillin in vitro, but the clinical significance is unknown, and it is generally recommended that they not be taken at the same time. Unless it is a serious infection, or drug sensitivity test suggests that these two drugs are really sensitive cases to consider under the guidance of the doctor to co-medication. Self-medication should be avoided.
