Four types of paromomycin regimen were evaluated: topical paromomycin alone, (14, 16, 20) topical paromomycin with methylbenzethonium chloride, (13, 18, 21) an ointment containing 15% paromomycin sulfate and 10% urea Paromo-U, (15), (17) and paromomycin 15% and gentamicin 0.5%.
The success rate of treatment among individuals receiving paromomycin only was 20;29, (14) 8;48, (16) and 5;30, (20) while the success rate of treatment among individuals receiving paromomycin with methylbenzethonium chloride was 14;34, (13) 14;34, (21) and 29;34.
The drug that is mostly used in topical treatments is paromomycin, while some other drugs such as imidazole and methylbenzethonium chloride [45-47].
