Pharmacokinetic evaluation of sildenafil as a pulmonary hypertension treatment
Abstract
INTRODUCTION: Sildenafil citrate is a potent, selective phosphodiesterase type 5 inhibitor approved for the treatment of pulmonary arterial hypertension (PAH) and plays an important role in the management of the disease.
AREAS COVERED: In this review, we focus on the current available information on the pharmacokinetics, pharmacodynamics, clinical efficacy and safety of sildenafil citrate in PAH through a MEDLINE literature search. Comparison of sildenafil citrate with tadalafil, another phosphodiesterase type 5 inhibitor was also performed.
EXPERT OPINION: In the last few years, considerable progress has been made in the understanding and treatment of PAH. Sildenafil citrate has multiple advantages and whether it is first-line treatment alone or in combination for the mild form of the disease, it is one of the treatments of choice. In terms of its future use, more studies are still needed to better evaluate the benefit/risk balance of sildenafil citrate in pediatric populations.
How strong is the evidence?
Evidence Hub reads this as a review, done in animal, not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
