What dry cough syrup can I give to a child who uses Azycin, Nebbud and Stodal?

Hello. Daughter 2.5 years, on Wednesday diagnosed bronchitis. If it gets worse, I had to give the antibiotic azycin and so I did. The daughter is suffocated by a drier cough (sometimes something coughing) and there is a terrible match, even rumbling from the throat. What syrup can I give to calm it down a little? Procz antyb still has nebbud ins and barn syrup. Thank you
