how long does it taked benazapril to work?

ok, thanks. do you know how long it takes to work? i'm wondering about getting his protein tested befoer the effects of the drug start to kick in. i'd just like to know. he got one pill yesterday. i wonder if i could postpone it stop it for a few days, get a test, and then start it. if he actually isn't losing protein, i would rather not be giving it to him because his pressure is normal. at least at this time. thanks a lot.
