  • Sildenafil improves insulin sensitivity and enhances insulin secretion in β cells, particularly in the presence of other depolarizing stimuli.
  • The drug operates independently of the traditional PDE5/cGMP pathway, primarily by increasing calcium influx through R-type voltage-dependent calcium channels.
  • This study positions sildenafil as a potential antidiabetic medication and provides insights into a novel mechanism for insulin secretion.
