title: Mequitazine in the treatment of hayfever.
abstract: A single-blind, multicentre, comparative clinical trial was performed in 59 hayfever sufferers to compare the efficacy of mequitazine 5 mg bd and terfenadine 60 mg bd over a period of 14 days. Clinical assessments of nasal and ocular symptoms were made on admission to the trial and after seven and 14 days treatment by both physicians and patients. Critical flicker fusion threshold was measured at each assessment. A global assessment of efficacy was determined by both the doctor and patient at the end of treatment. Patients also completed a daily diary card. Thirty patients on mequitazine and 22 on terfenadine completed the trial. There were seven dropouts (five on terfenadine and two on mequitazine). Both treatments were equally effective in reducing the severity of symptoms over the 14 days of treatment. The overall assessment at the end of treatment showed no important significant differences between the two drugs. According to the physicians, 60 per cent of the mequitazine-treated patients and 63 per cent of the terfenadine-treated patients had an excellent or good response. Patients assessed their response as excellent or good in 56 and 62 per cent of cases respectively. Neither drug significantly impaired performance.
