pl confirm any intera-action in drug.
my reading say that asprin and glucosamine togather alongwith ace inhibator and sildenafil
may become risky .can this drug combination creat palpitation?--because blood become thin and flow become fast because of vain opening and thin blood.
is it? what should be done before doctor come if palpitation or hypotension arise?can i take this drug for one month?or second openion?

Answer
Sildenafil (Viagra) [was researched as a HTN drug initially before the wonders of good erections were noticed] will have a blood pressure lowering property especially when in combination with other blood pressure lowering medications (nitrates, ACE inh., CCBs).  Other than this I can make no other recommendations.  Best to seek this answer from your prescribing physician.
