Insights
Sildenafil citrate may safely and effectively treat pulmonary hypertension (PH) in infants with bronchopulmonary dysplasia (BPD). Continued treatment until PH resolution might reduce mortality in this serious condition.
Area of Science:
- Pediatric Pulmonology
- Neonatology
- Pharmacology
Background:
- Infant pulmonary hypertension (PH) secondary to bronchopulmonary dysplasia (BPD) is a significant cause of morbidity.
- Sildenafil citrate, a phosphodiesterase-V inhibitor, is a first-line therapy for idiopathic PH.
- Limited evidence exists for sildenafil's efficacy in managing PH associated with BPD.
Purpose of the Study:
- To review current evidence on sildenafil citrate for treating PH in BPD.
- To evaluate sildenafil as monotherapy and in combination with other agents.
- To assess the potential impact of sildenafil on mortality when continued until PH resolution.
Main Methods:
- Review of existing literature and clinical knowledge on sildenafil for PH in BPD.
- Analysis of safety and efficacy data for sildenafil monotherapy.
- Evaluation of combination therapy approaches including sildenafil.
Main Results:
- Sildenafil citrate appears to be safe for treating PH in BPD.
- Evidence suggests potential efficacy for sildenafil, alone or in combination.
- Continuing sildenafil until PH resolution may reduce mortality.
Conclusions:
- Sildenafil citrate is a potentially valuable therapeutic option for infants with PH and BPD.
- Further research is warranted to confirm efficacy and optimal treatment duration.
- Early and continued sildenafil treatment may improve outcomes in this vulnerable population.
Abstract:
Pulmonary hypertension (PH) secondary to bronchopulmonary dysplasia (BPD) in infants remains a serious concern and continues to cause significant morbidity despite improvements in both quality of life and survival for patients. One of the potential agents that might help is sildenafil citrate, a phosphodiesterase-V inhibitor used a first line therapy for idiopathic PH. However, only limited evidence exists for its use as either monotherapy or part of a combination approach towards the management of PH in BPD. The evidence and current knowledge is presented for sildenafil alone and in combination with other disease modifying agents to treat PH in the presence of BPD. We have previously suggested that sildenafil appears to be safe and possibly effective in this condition. We present the evidence that if continued until PH resolution, there might be reduced mortality in this debilitating disease.
