To reduce the development of drug-resistant bacteria and maintain the effectiveness of Zithromax (azithromycin) and other antibacterial drugs, Zithromax (azithromycin) should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. DESCRIPTION ZITHROMAX (azithromycin tablets and azithromycin for oral suspension) contain the active ingredient az...

RP 59500 is a new injectable streptogramin composed of two synergistic components (quinupristin and dalfopristin) which are active against a number of erythromycin-susceptible and -resistant gram-positive bacteria. The following experiments investigate the ability of RP 59500 to prevent experimental endocarditis due to either of two erythromycin-susceptible streptococcal isolates or their const...

Streptococcus pyogenes is the major bacterial pathogen responsible for acute pharyngitis in children. Oral penicillin is the drug of choice for streptococcal pharyngitis, while macrolides are an alternative option for patients allergic to penicillin. The frequent use of macrolides promotes the spread of erythromycin resistance (1-2), but reducing the use of these antibiotics has been correlated...

The in vitro susceptibility of human isolates of Pasteurella multocida to oral antimicrobial agents from our current study and from a review of the literature suggests that dicloxacillin (oxacillin), erythromycin, clindamycin, cephalexin, cefaclor, and cefadroxil should not be used for empiric therapy of animal bite wounds. Agents that were consistently active against P. multocida were penicill...

The efficacy of erythromycin was assessed in the treatment of 14 children aged 4 to 13 years with refractory chronic constipation, and presenting megarectum and fecal impaction. A double-blind, placebo- controlled, crossover study was conducted at the Pediatric Gastroenterology Outpatient Clinic of the University Hospital. The patients were randomized to receive placebo for 4 weeks followed by ...

A fixed drug eruption (FDE) is not difficult to diagnose, given its clinical characteristics. However, the causative agent can be difficult to identify, particularly when the patient denies ingestion of any drugs. To the best of our knowledge, we present herein the first reported case of an FDE caused by antibiotics taken in food; doxycycline and erythromycin contained in pork and fish. A 57-ye...

Azithromycin, 9-Deoxo-9a-aza-9a-methyl-9a-homoerythromycin a dihydrate, is a semi-synthetic 15-membered azalide antibiotics derived from erythromycin. Its chemical structure differs from that of erythromycin by the insertion of methyl-substituted nitrogen at position 9a in the lactone ring. This modification results in the improved acid stability associated with more reliable and greater oral b...
