It is supplied as a pill in a fixed dose of 2.5 mg hydrochlorothiazide plus 6.25 mg bisoprolol. The product belongs to the therapeutic class of antihypertensive agents and is primarily prescribed to lower high blood pressure. Secondary uses may include adjunctive therapy for certain cardiovascular conditions, though these are not formally approved. ## Quick Reference Facts **Active Ingredient** : Hydrochlorothiazide and Bisoprolol **Form** : pill 2.5/6.25 mg **Primary and Off-Label Uses** : • Hypertension (primary) : • Chronic heart failure (off-label) : • Angina pectoris (off-label) ## What is Ziac? Ziac is the generic version of medications that combine the active compounds hydrochlorothiazide and bisoprolol. It is classified as an antihypertensive combination product. The formulation pairs a diuretic, which reduces fluid volume, with a β-blocker that slows heart rate and lowers cardiac output. While the brand name Ziac is marketed by Pfizer, the generic formulation is available from multiple manufacturers and provides a cost-effective alternative. Because it is a generic, Ziac offers the same therapeutic effect as the brand-name product, fulfilling bioequivalence standards set by regulatory agencies. ## How Ziac Works Hydrochlorothiazide acts on the distal convoluted tubule of the kidney, inhibiting sodium-chloride reabsorption. This promotes excretion of sodium, chloride, and water, decreasing plasma volume and thereby lowering blood pressure. Bisoprolol selectively blocks β1-adrenergic receptors in the heart, reducing heart rate, myocardial contractility, and renin release. The combined effect produces a complementary reduction in systemic vascular resistance and cardiac output, leading to more consistent blood-pressure control than either component alone. Both agents are metabolized primarily by the liver and excreted renally; the half-life of bisoprolol is approximately 10-12 hours, while hydrochlorothiazide’s effect persists for 24 hours, supporting once-daily dosing. ## Conditions Treated with Ziac - **Essential Hypertension** Ziac lowers elevated systolic and diastolic pressures by decreasing fluid volume (hydrochlorothiazide) and reducing cardiac output (bisoprolol). This dual mechanism addresses two major contributors to hypertension, improving blood-pressure control in patients who require more than single-agent therapy. - **Isolated Systolic Hypertension in the Elderly** The diuretic component mitigates volume overload common in older adults, while bisoprolol attenuates the age-related increase in arterial stiffness, offering a balanced approach for this subgroup. - **Adjunctive Therapy in Resistant Hypertension** When blood pressure remains above target despite three or more antihypertensives, adding Ziac can provide additional lowering through its complementary mechanisms, often reducing the need for higher doses of other agents. ## Is Ziac the Right Medication for You? Ziac is most suitable for adults with stage 1 or stage 2 hypertension who have not achieved target blood pressure with monotherapy or who benefit from combined diuretic-β-blocker therapy. It is also appropriate for patients who require a low-dose β-blocker due to comorbid conditions such as tachyarrhythmias. Contraindications include severe renal impairment (eGFR < 30 mL/min/1.73 m²), uncontrolled asthma, severe bradycardia (< 50 bpm), and known hypersensitivity to either component. Caution is advised in patients with diabetes, gout, or electrolyte disturbances, as the diuretic may exacerbate these conditions. Physicians often prefer Ziac when a patient needs both volume reduction and heart-rate control without adding multiple separate pills. ## Buying Ziac from [our online pharmacy](https://liabilis.com/order-ziac-online-en.html) ### Why Choose Our Service?

Dose adjustments may be made by a healthcare professional based on blood-pressure response and tolerability. - **Missed Dose** If a dose is forgotten, take it as soon as remembered unless it is within 12 hours of the next scheduled dose. In that case, skip the missed pill and resume the regular dosing schedule. Do not double-dose. - **Overdose** Symptoms of overdose may include excessive hypotension, bradycardia, dizziness, or fainting. Seek emergency medical care immediately; treatment typically involves supportive measures such as intravenous fluids, atropine for severe bradycardia, and monitoring of cardiac rhythm. - **Precautions** - Avoid consuming large amounts of alcohol, which can potentiate hypotensive effects. - Do not operate heavy machinery or drive until you know how Ziac affects you. - Taking the medication with a substantial meal may reduce peak plasma concentration of bisoprolol, but does not necessitate a dose change. ## Safety Information ### ⚠️ Who Should Not Take Ziac - Patients with severe renal impairment (eGFR < 30 mL/min/1.73 m²). - Individuals with known hypersensitivity to hydrochlorothiazide, bisoprolol, or any excipients. - Patients with uncontrolled asthma or chronic obstructive pulmonary disease where β-blockade may precipitate bronchospasm. - Those with symptomatic bradycardia (heart rate < 50 bpm) or second- or third-degree atrioventricular block without a pacemaker. ### Common Side Effects - **Electrolyte imbalance** - mild hyponatremia or hypokalemia may occur due to the diuretic effect; monitoring electrolytes is advised. - **Fatigue or dizziness** - related to blood-pressure lowering; typically transient. - **Cold extremities** - β-blocker-induced peripheral vasoconstriction, usually mild. ### Serious Side Effects (Seek Immediate Medical Help) - Severe hypotension (systolic < 90 mmHg) leading to syncope. - Acute heart block or worsening heart failure. - Allergic reactions such as rash, swelling, or anaphylaxis. ### Drug & Food Interactions - **Non-steroidal anti-inflammatory drugs (NSAIDs)** - may blunt the antihypertensive effect of hydrochlorothiazide. - **Potassium-sparing diuretics or supplements** - can raise serum potassium when combined with hydrochlorothiazide, risking hyperkalaemia. - **Other β-blockers** - additive cardiac depression; avoid concurrent use unless directed. - **Grapefruit juice** - may increase bisoprolol plasma levels by inhibiting CYP3A4 metabolism; limit intake. ## Off-Label and Investigational Uses of Ziac - **Chronic Heart Failure** - Clinical studies suggest that low-dose bisoprolol combined with a thiazide diuretic may improve symptom control and reduce hospitalizations, though this indication is not formally approved. - **Angina Pectoris** - Some cardiology guidelines reference β-blocker plus diuretic combinations for relief of exertional chest pain, but evidence remains limited and off-label. - **Prevention of Stroke in High-Risk Patients** - Observational data indicate that aggressive blood-pressure lowering with combination therapy can lower stroke incidence; however, Ziac is not specifically labeled for this purpose. All off-label applications should be undertaken only under the direct supervision of a qualified healthcare provider. ## Storage & Handling - Store tablets at controlled room temperature (20 °C-25 °C). - Protect from excess moisture and direct sunlight. - Keep out of reach of children. - Do not use tablets beyond the expiration date printed on the packaging. - Dispose of unused medication through a pharmacy take-back program or according to local regulations to avoid environmental contamination. ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I travel internationally with Ziac?** Yes, but you should carry a copy of the prescription label and a declaration of medication in case customs request verification. - **Will taking Ziac affect my ability to climb mountains or engage in high-altitude activities?** The diuretic component may increase fluid loss, so adequate hydration is essential at altitude. Monitor blood pressure and adjust fluid intake accordingly. - **Is it safe to drink coffee while on Ziac?** Moderate caffeine intake does not significantly interact with either component, but excessive consumption may elevate heart rate, counteracting bisoprolol’s effect. **Product & Formulation Details** - **What do Ziac tablets look like?** They are round, film-coated tablets, typically white with a scored line to facilitate splitting if required. - **Are there any inactive ingredients that could cause allergic reactions?** Ziac tablets may contain lactose, microcrystalline cellulose, and magnesium stearate. Patients with known allergies to these excipients should verify with the manufacturer. **Regulatory & Safety Nuances** - **Will Ziac appear on a standard urine drug test?** Neither hydrochlorothiazide nor bisoprolol is screened for in typical employment drug tests, as they are not controlled substances. - **Can Ziac be used by athletes subject to anti-doping regulations?** Both components are permitted; however, athletes should disclose medication use to their governing body to avoid inadvertent violations. - **Is Ziac classified as pregnancy category?** Bisoprolol is generally classified as Category C, indicating risk cannot be ruled out. Hydrochlorothiazide is also Category C. Women who are pregnant or planning pregnancy should discuss risks with their healthcare provider. **Scientific & Clinical Curiosity** - **When was the combination of bisoprolol and hydrochlorothiazide first approved?** The fixed-dose combination received regulatory approval in the United States in the early 2000s, following separate approvals of each active ingredient. - **How does Ziac compare to other antihypertensive combos like amlodipine/valsartan?** Ziac targets blood-pressure reduction through diuresis and β-blockade, whereas amlodipine/valsartan combines calcium-channel blockade with angiotensin-II receptor antagonism. The choice depends on patient comorbidities and tolerability profiles. ## Glossary **β-Blocker** : A class of drugs that inhibit β-adrenergic receptors, reducing heart rate and contractility. **Thiazide Diuretic** : A medication that promotes excretion of sodium and water by inhibiting sodium-chloride reabsorption in the distal kidney tubule. **Bioequivalence** : Demonstration that a generic product delivers the same amount of active ingredient to the bloodstream as the reference brand product. **eGFR** : Estimated glomerular filtration rate, a measure of kidney function used to adjust dosing of renally cleared drugs. ## Disclaimer The information provided about Ziac is for general knowledge only.
