Antifungal or antibacterial compositions are commonly used as lotions, creams or ointments. Also, in some cases it is difficult to determine whether the skin condition is due to a bacterial factor or a fungus. [0003] One approach to treating skin diseases is eradication by trial and error. The antibacterial or antifungal composition is administered alternately to monitor response and modify treatment. The main disadvantage of this method is that multiple sessions per day are required during the treatment period. This is inconvenient and uneconomical ...
