Comparative effectiveness of oral dexamethasone vs. oral prednisolone for acute exacerbation of asthma: A randomized control trial.
Journal of Family Medicine and Primary Care 2022 April
BACKGROUND: Acute exacerbation of asthma is a common condition leading to emergency visits. Prednisolone is a commonly prescribed drug in the standard management of acute exacerbation of asthma along with other drugs. This study was planned to see the efficacy of oral dexamethasone when compared with oral prednisolone in the management of acute exacerbation of asthma.
METHODS: A single-center pilot study in the form of randomized control trial was done by recruiting children aged 2-14 years diagnosed with acute asthma exacerbation with mild to moderate severity. A total of 88 patients received oral dexamethasone (0.3 mg/kg) in two doses 24 h apart, which was compared with 87 patients who received oral prednisolone (1 mg/kg) in two divided doses 12 h apart for 5 days. The patients were assessed at the time of admission (zero hour), at 4th hour, and on the 5th day by various parameters such as respiratory rate, use of accessory muscles, Pediatric Respiratory Assessment Measure (PRAM) score, peak expiratory flow rate (PEFR), 6-h admission stay, and rate of hospital admission.
RESULTS: Baseline demographic profile, clinical characteristics, comorbidities, indoor pollution, and use of Metered Dose Inhaler (MDI) among the two study groups were comparable. Six-hour emergency stay and rate of admission were significantly lower in the dexamethasone group ( P < 0.05). Improvement in PRAM score, PEFR, use of accessory muscles, and respiratory rate was also better in dexamethasone group at the 4th hour and 5th day ( P < 0.05). In addition, oral dexamethasone was shown to have less incidence of vomiting/gastritis than prednisolone ( P < 0.05).
CONCLUSION: Oral dexamethasone can be considered a reliable and better option as compared with prednisolone due to its faster action and minimal side effects.
