One study suggested that topical ketanserin is more effective than clioquinol cream or zinc paste. Topical phenytoin (two studies) may be more effective than saline dressing regarding ulcer healing. For the other dressings the results were equivocal. Canvas shoes were a little better than PVC-boots, but not significantly, and the effect of double rocker shoes compared to below-knee plasters was no different in promoting the healing of ulcers. No side effects were documented.
There is a lack of high quality research in the field of ulcer prevention and treatment in leprosy. New trials should follow the current standards for design and reporting of randomised controlled trials.
Use of topical ketanserin for the treatment of ulcers in leprosy patients.
A comparative study was carried out in which 66 leprosy patients with ulcers were randomly divided in two groups of 33 patients each: Group A (experimental group) was treated with ketanserin gel (2%) and group B with clioquinol cream and/or Lassar paste during a three month period. At the end of the study, when ulcer sizes in the two groups were compared, the group treated with topical ketanserin showed superior results (p < 0.001 using Kolmogorov-Smirnov's test). We conclude that the drug is useful as coadjuavant treatment for healing ulcers in these patients.
