UW says Nitrates should not be followd after Viagra until 24 hrs

But says a-Blocker should not be followd after Viagra until 4 hrs?

i think it shud be same because We are using Viagra 1st?

I think its b/c of more potent n longer lasting effects of Nitrates in venous/arterial vasculature compared to BB Blockers

Yeh that can be reason but i thought may be its typo 2 for 24 hrs...its important there are alot questions on this
