PerioGard (Chlorhexidine Gluconate Oral Rinse, 0.12%) is an oral rinse containing 0.12% chlorhexidine gluconate [N, N”-bis(4-chlorophenyl)-3, 12-diimino-2, 4, 11, 13-tetraazatetradecane-diimidamide di-D-gluconate] in a base containing water, 11.6% alcohol, glycerin, PEG-40 sorbitan diisostearate, flavor, sodium saccharin, and FD&C Blue No. 1. PerioGard® oral rinse is a near-neutral solution (pH range 5-7). Chlorhexidine gluconate is a salt of chlorhexidine and gluconic acid, with a molecular formula of C22H30Cl2N10·2C6H2O7 and a molecular weight calculated to be 897.77.
Chlorhexidine gluconate provides antimicrobial activity during oral rinsing. The clinical significance of 0.12% chlorhexidine gluconate oral rinse’s antimicrobial activities is not clear. Microbiological sampling of plaque has shown a general reduction of counts of certain assayed bacteria, both aerobic and anaerobic, ranging from 54-97% through six months’ use. Use of a chlorhexidine gluconate oral rinse in a six-month clinical study did not result in any significant changes in bacterial resistance, overgrowth of potentially opportunistic organisms, or other adverse changes in the oral microbial ecosystem. Three months after chlorhexidine gluconate use was discontinued, the number of bacteria in plaque had returned to baseline levels and the resistance of plaque bacteria to chlorhexidine gluconate was equal to that at baseline.
