Quinolone levels in serum and maxillofacial tissues under ibuprofen co-administration following surgical trauma.

ABSTRACT

Administration of antibiotics is considered to be an important factor, during or after operational procedures in the maxillofacial area, in order to avoid post-surgical complications. Furthermore, administration of anti-inflammatory drugs is often prescribed for control of the post-operative pain. The aim of this study was to determine the levels of quinolones in serum and tissues (parotid gland, tongue, mandible), during traumatic injury in the oral cavity, with or without co-administration of ibuprofen, a non-steroidal anti-inflammatory drug. Four groups of Wistar rats, (A, B control), (C, D experimental) were used. In the experimental group, traumatic injury was performed through the whole length of the cheek. Groups B and D received ibuprofen. The quinolone levels in serum and tissues were estimated by the inhibition zone of B. subtilis. Free fatty acid (FFA) levels and the adrenal weight, considered as a stress index, were increased in trauma groups. Quinolone concentrations in serum and in most of the tissues were significantly higher in the experimental groups compared to the controls. However, the co-administration of ibuprofen caused a higher increase of the quinolone levels in the control animals than in the experimental groups.
