How does ZIAC work?

How does ZIAC work?

ZIAC is a combination of two different medications that both work to lower blood pressure.
Bisoprolol is a cardioselective beta blocker. It works by blocking chemicals that attach to receptors on the heart. This slows down your heart rate and lowers your blood pressure.
Hydrochlorothiazide is a thiazide diuretic (water pill) that makes you urinate more. It works in your kidneys to remove extra water and certain electrolytes, which helps lower your blood pressure.

How do I take ZIAC?

How do I take ZIAC?

ZIAC is typically started at 2.5 mg/6.25 mg (bisoprolol / hydrochlorothiazide) by mouth once daily. If needed, your provider will raise your dose every 2 weeks. The maximum recommended dose of Ziac is 20 mg/12.5 mg (bisoprolol / hydrochlorothiazide) by mouth once daily.

Sinus bradycardia (a type of slow heartbeat)
Heart block greater than first degree
Shock
Heart failure
Not producing urine
Allergy to sulfa-containing medications

    Effects of other drugs, drug classes and over-the-counter products on ZIAC

    Effects of other drugs, drug classes and over-the-counter products on ZIAC

    The following medications may interact with ZIAC:

  • Catecholamine-depleting drugs may have an additive effect when given with beta-blocking agents.
  • Patients may be unresponsive to the usual doses of epinephrine used to treat allergic reaction.
  • CYP2D6 Inhibitors are likely to increase ZIAC concentration.
  • Concomitant use of glycosides, clonidine, and diltiazem and verapamil with beta-blockers can increase the risk of bradycardia.
  • Beta-blockers including ZIAC, may exacerbate the rebound hypertension that can follow the withdrawal of clonidine.
  • Alcohol, barbiturates, or narcotics: Potentiation of orthostatic hypotension may occur.
  • Antidiabetic drugs (oral agents and insulin) dosage adjustment of the antidiabetic drug may be required.
  • Other antihypertensive drugs: Additive effect or potentiation.
  • Cholestyramine and colestipol resins: Cholestyramine and colestipol resins bind the hydrochlorothiazide and reduce its absorption.
  • Corticosteroid, ACTH: Possible electrolyte depletion, particularly hypokalemia.
  • Pressor amines (e.g., norepinephrine): Possible decreased response to pressor amines.
  • Skeletal muscle relaxants, nondepolarizing (e.g., tubocurarine): Possible increased responsiveness to the muscle relaxant.
  • Lithium: Generally should not be given with diuretics.
  • Non-steroidal anti-inflammatory drugs: May reduce the diuretic, natriuretic, and antihypertensive effects of loop, potassium-sparing and thiazide diuretics.
