Astemizole suspension in the maintenance treatment of paediatric hay fever: a comparison with terfenadine suspension.

A study was carried out in general practice during the summer months of 1985 to compare the efficacy and tolerance of astemizole suspension with terfenadine suspension in the treatment of paediatric hay fever. The 65 patients who entered the study were all aged between 6 and 12 years and had suffered from hay fever in at least one previous season. Each child was randomly allocated to receive either 5 ml astemizole suspension (1 mg/ml) once daily or 5 ml terfenadine suspension (6 mg/ml) twice daily for a period of 8 weeks on a single-blind basis. Symptom scores assessed by the patient (or parent/guardian) on two visual analogue scales for ocular and nasal symptoms showed no significant difference between the treatment groups, neither did an analysis of visual analogue scores for runny nose, blocked nose, wheeze, sneezing or eye symptoms assessed by the investigator on entry or after 4 and 8 weeks. The global assessments made by the investigator at 4 weeks and the patient at 8 weeks, however, indicated significantly better overall symptom control in the astemizole group. Both treatments were well tolerated, side-effects being few and minor.
