Megazol, one of a number of related 5‐nitroimidazoles, can be dissolved in dimethylsulphoxide and the solution can be converted into a gel by the addition of hydroxypropylcellulose which facilitates the ease and accuracy of administration. This megazol gel, when used in combination with melarsoprol (3.6%) in propylene glycol gel, will cure experimental CNS‐trypanosomiasis in mice. A single application of 0.1 ml of melarsoprol (3.6%) gel plus 0.1 ml of either 8 or 16 mg/ml megazol gel successfully treated experimental CNS‐trypanosomiasis while two consecutive days' treatment with 0.05 ml melarsoprol and 0.1 ml of 16 or 32 mg/ml megazol gels also produced satisfactory cures.
