- Background
Chlorquinaldol was used historically as a topical antiseptic under the trade name Sterosan.5 It was marketed in the 1950s as an iodine-free alternative which was also unrelated to sulfa drugs or hormones. Chlorquinaldol is currently approved by the European Medicines Agency as a combination tablet with promestriene for the treatment of bacterial vaginosis.6

- Pharmacodynamics
Chlorquinaldol is bacteriocidal in both gram positive and gram negative bacteria. It is more effective in targeting gram positive bacteria, particularly staphylococci.1
- Mechanism of action
The mechanism by which Chlorquinaldol exerts it's bacteriocidal effect is unknown. 8-hydroxyquinolines are known to be bidentate chelators of several metal ions which act as critical enzyme cofactors.3 However, the addition of exogenous metal ions does not appear to alter the minimum inhibitory concentration for mycobacterium tuberculosis suggesting that the primary mechanism does not rely on chelation.4
- Absorption
There is a high degree of variability in the extent of absorption of topically applied chorquinaldol preparations.2 It is reported to be between 4.2 and 23.5% of the applied dose. This is quite low compared to orally administered preparations which displayed 67.6% absorption in the same study.
