One could presume any kind of vasodilator would potentially be an issue here, although studied rationale does not exist. The issue would probably be short-lived at best as the half-life of NO is VERY quick! In that setting, rebound HTN would be more of an issue with shorter-spurt PDE5 inhibitors (i.e. - Viagra...possibly Levitra)- than something like cialis (but we must consider a dose-response relationship here ... 5mg daily is not the same as 20mg every 3rd day).
