b.p. medication

[gipaeniug]

What are your thoughts on the use of blood pressure medication (amlodipine/calcium channel blockers) for screenings/initial study dates? Is it possible to get away with taking one the night before a screening or study date? Would it show up on a urinalysis or blood screening? And would the medication produce lowered bp within a day of first time use? 

Thoughts?

Thanks a million!!!
