Ziac (bisoprolol and hydrochlorothiazide) is currently available in both brand-name and generic form. Generic Ziac tablets are available in three strengths and manufactured by various companies, including Sandoz, Mylan Pharmaceuticals, and Watson Laboratories, Inc. All of these generic versions have been given an "AB" rating by the FDA, which means they are considered equivalent to brand-name Ziac.
Ziac® (bisoprolol and hydrochlorothiazide) is a prescription medication. It contains a beta blocker (bisoprolol) and a thiazide diuretic (hydrochlorothiazide). It is approved for the treatment of high blood pressure (hypertension).
Brand-name Ziac is manufactured by Duramed Pharmaceuticals, Inc. However, the patents for this drug have expired, and generic Ziac is now available.
Generic Ziac tablets are available in the following strengths:
- Bisoprolol and hydrochlorothiazide 2.5 mg/6.25 mg
- Bisoprolol and hydrochlorothiazide 5 mg/6.25 mg
- Bisoprolol and hydrochlorothiazide 10 mg/6.25 mg.
A few different companies make a generic version of Ziac, such as:
- Actavis US
- Mylan Pharmaceuticals
- Watson Laboratories, Inc.
All generic medications must have certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns a rating to each one. An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic bisoprolol and hydrochlorothiazide versions currently available have an "AB" rating, which means they should be equivalent to Ziac.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that could cause problems for people with allergies or sensitivities.
