Summary
Mebendazole tablets which are produced by most pharmaceutical manufacturers, including the State Pharmaceutical Manufacturing Corporation (SPMC) of Sri Lanka, contain a mixture of polymorphs A and C. However, there is some evidence to show that mebendazole polymorph C is the only form effective against the soil-transmitted helminths. This protocol describes a stratified, randomized, placebo-controlled trial that examined the efficacy of different mebendazole polymorphs produced by the SPMC in the treatment of hookworm infections.
