    Summary
    VIP (6 pmol/kg/min) infusion caused significant (p less than 0.01) increase in peak expiratory flow rate (PEFR) of 26 +/- 9 (SEM) l/min after 30 minutes infusion compared with a bronchodilation of 39 +/- 19 l/min seen with salbutamol (5 mcg/min).

    In inpatients recovering from severe acute asthma, the bronchodilation with VIP infusion was smaller than with salbutamol.
