Antibacterial preparations
Although there are a great many antibacterial drugs presented in topical preparations some are potentially hazardous and frequently their use is not necessary if adequate hygienic measures can be taken. Moreover, not all skin conditions that are oozing, crusted, or characterised by pustules are actually infected. Topical antibacterials should be avoided on leg ulcers unless used in short courses for defined infections; treatment of bacterial colonisation is generally inappropriate. To minimise the development of resistant organisms it is advisable to limit the choice of antibacterials applied topically to those not used systemically.

Antifungal preparations
Most localised fungal infections are treated with topical preparations.
