An open comparative trial of Vanquin tablets and pripsen granules in the treatment of threadworm infestation

Thirty-eight patients presenting to their general practitioner with threadworm infestation were admitted to an open, comparative, multicentre trial of Vanquin tablets and Pripsen granules. Efficacy and tolerance were assessed. Twelve of nineteen patients treated with Vanquin had positive results from a peri-anal skin test at the start of treatment, all results were negative after twenty-one days. Fourteen of nineteen patients treated with Pripsen had positive results at the start of treatment and two of these had positive results after twenty-one days. One patient treated with Vanquin and five treated with Pripsen reported side-effects.
