[A sulfadiazine-tetroxoprim combination (co-tetroxazine) in the treatment of the acute exacerbation of chronic bronchitis].

After considering the bacterial flora which is most common in relapses in patients with bronchitis, 40 patients with chronic bronchitis have been treated with tetroxoprim a recently synthetized benzyl pyrimidine associated with sulfadiazine. One 350 mg tablet was administered every 12 hours for different periods, from 7 to 14 days. This study has shown how tetroxoprim has a wide antibacterial range, how it is well tolerated and extremely powerful in treating relapses of chronic infections in bronchi.
