Cardiovascular Considerations

Combination therapy for the treatment of hypertension should be individualized for each patient. Potential advantages for bisoprolol and hydrochlorothiazide combination therapy may include improved compliance and synergistic reductions in blood pressure with an accomplished reduction in side effects. Beta-blockers and thiazide diuretics are first-line therapies for the treatment of hypertension.


Dental Health: Local Anesthetic/Vasoconstrictor Precautions

No information available to require special precautions


Dental Health: Effects on Dental Treatment

Noncardioselective beta-blockers (ie, propranolol, nadolol) enhance the pressor response to epinephrine, resulting in hypertension and bradycardia. This has not been reported for bisoprolol, a cardioselective beta-blocker. Therefore local anesthetic with vasoconstrictor can be safely used in patients medicated with bisoprolol. Many nonsteroidal anti-inflammatory drugs such as ibuprofen and indomethacin can reduce the hypotensive effect of beta-blockers after 3 or more weeks of therapy with the NSAID. Short-term NSAID use (ie, 3 days) requires no special precautions in patients taking beta-blockers.
