    Abstract:
    Roxithromicin is a semisynthetic macrolide antibiotic, with similar antibacterial activity to erythromycin. It is characterized by an excellent pharmacokinetic profile and a good tissue penetration. Particularly at the dose of 300 mg per day the dental tissue diffusion is extremely good, and this is important to oppose the oral cavity infections. Oral cavity infections can be either odontogenic or non odontogenic. Odontogenic infections are typically primary and are caused by commensal bacteria (oral Streptococci, Bacteroides sp., Veillonella sp. and Fusobacterium sp.). The antibacterial spectrum of roxithromycin is very large and includes many of the most frequent strains responsible for oral cavity infections. A very interesting characteristic of roxithromycin is its penetration in macrophages (uptake) that allow a more rapid inhibition of bacterial activity. To evaluate the clinical efficacy and tolerance of roxithromycin in the treatment of odontogenic infections, an open study was performed. This study evaluated both the microbiological and clinical aspects. Thirty patients (21 females and 9 males) who had not been previously treated with antibiotic or antibacterial drugs, affected by infective dysodontiasis, gingivitis and periodontal diseases, received 300 mg per day (once a day) of roxithromycin for an average period of 6 days. The symptomatology considered was: intumescence, redness, pain, lymphangitis and presence of trismus. Clinical symptomatology was assessed at the start and at the end of the treatment. The symptomatological improvement due to roxithromycin was rapid and very effective. After 6 days of therapy, the improvement was statistically significant (p < 0.01) compared to basal conditions. No adverse reactions or side-effects were complained during the study. No changement were detected in laboratory parameters.(ABSTRACT TRUNCATED AT 250 WORDS)
