Generic Zestoretic Information

Introduction

Zestoretic is a fixed‑dose combination tablet that contains the angiotensin‑converting‑enzyme (ACE) inhibitor lisinopril and the thiazide‑type diuretic hydrochlorothiazide. It belongs to the blood‑pressure medication group and is prescribed principally for the management of essential (primary) hypertension, either as initial therapy or when monotherapy does not achieve target blood‑pressure goals. In the United Kingdom the product is regulated by the Medicines and Healthcare products Regulatory Agency (MHRA) and is available on prescription for adult patients whose cardiovascular risk warrants combined ACE‑inhibitor and diuretic therapy.

What is Zestoretic?

Zestoretic is a tablet that delivers 20 mg, 40 mg or 80 mg of lisinopril together with 12.5 mg of hydrochlorothiazide, depending on the strength. The combination leverages two complementary mechanisms: inhibition of the renin‑angiotensin‑aldosterone system (RAAS) and promotion of renal sodium‑water excretion. The product is manufactured under licence by several pharmaceutical companies; in Europe the original brand was developed by AstraZeneca. Although Zestoretic is a branded formulation, its active ingredients are identical to those found in well‑known lisinopril products (e.g., Prinivil, Zestril) and thiazide diuretics (e.g., Hydrodiuril). The tablet is supplied in blister packs of 28 or 30 units, intended for once‑daily oral intake.

How Zestoretic Works

• Lisinopril component – Lisinopril is a selective ACE inhibitor. By blocking the conversion of angiotensin I to angiotensin II, it reduces vasoconstriction, aldosterone secretion, and sympathetic activation. The net effect is lower systemic vascular resistance and modest diuresis due to reduced sodium retention. Peak plasma concentrations of lisinopril are reached within 6–8 hours after oral dosing, and the drug’s half‑life is approximately 12 hours, supporting once‑daily administration.

• Hydrochlorothiazide component – Hydrochlorothiazide inhibits sodium‑chloride reabsorption in the distal convoluted tubule, increasing urinary sodium and water loss. This reduces plasma volume, thereby lowering cardiac preload and contributing to a fall in blood pressure. The diuretic effect appears within 2 hours and persists for up to 24 hours, complementing the longer‑acting lisinopril.

The two agents together produce an additive antihypertensive effect, often allowing a lower dose of each component than would be required if they were given separately, which can lessen the incidence of dose‑related adverse events.

Conditions Treated with Zestoretic

• Essential (primary) hypertension – Elevated systolic or diastolic pressures are a major contributor to cardiovascular morbidity in the UK, affecting an estimated 30 % of adults over 45 years. Combination therapy with an ACE inhibitor and a thiazide diuretic is recommended by NICE (NG136) when monotherapy fails to achieve a target of <130/80 mmHg in high‑risk patients.

• Hypertension with concomitant volume overload – Patients with mild heart failure or chronic kidney disease often have fluid retention; the diuretic component addresses excess volume while the ACE inhibitor offers renal protection and after‑load reduction.

• Secondary prevention after myocardial infarction – Although Zestoretic is not a first‑line post‑MI regimen, clinicians may employ it when a patient already requires both an ACE inhibitor and a thiazide diuretic for blood‑pressure control, provided there are no contraindications.

These indications are supported by large‑scale trials such as the ALLHAT and ASCOT studies, which demonstrated superior blood‑pressure lowering and reduction in major cardiovascular events when ACE inhibitors were combined with thiazide diuretics.

Who is Zestoretic For?

• Adults with stage 2 hypertension (clinic systolic ≥ 160 mmHg or diastolic ≥ 100 mmHg) who have not reached target pressure on monotherapy.
• Patients requiring a diuretic due to peripheral edema, mild heart failure, or early chronic kidney disease, provided estimated glomerular filtration rate (eGFR) is ≥ 30 mL/min/1.73 m².
• Individuals intolerant to higher doses of either component alone, as the fixed‑dose product permits lower individual doses while maintaining efficacy.

Zestoretic is not appropriate for:

• Pregnant or breastfeeding women (ACE inhibitors are contraindicated).
• Patients with a history of angio‑edema related to ACE‑inhibitor therapy.
• Severe renal impairment (eGFR < 30 mL/min/1.73 m²) or anuria.
• Hyper‑kalaemia (serum potassium > 5.5 mmol/L) without correction.

Clinical judgment and regular monitoring are essential before initiating therapy.

Risks, Side Effects, and Interactions

Common

• Dry cough (ACE‑inhibitor class effect)
• Light‑headedness or dizziness, especially after the first dose (orthostatic hypotension)
• Increased urination, mild electrolyte disturbance (hypokalaemia)

Rare

• Taste disturbances (dysgeusia)
• Skin rash or pruritus
• Elevated serum creatinine (>30 % increase from baseline)

Serious

• Angio‑edema involving face, tongue, or airway – requires emergency medical attention.
• Severe hyper‑kalaemia (K⁺ > 6. mmol/L) that can precipitate cardiac arrhythmia.
• Acute kidney injury, particularly in patients with bilateral renal artery stenosis or volume depletion.

Clinically Relevant Drug‑Drug Interactions

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – may blunt antihypertensive effect and increase risk of renal impairment.
• Potassium‑sparing diuretics (e.g., spironolactone) or potassium supplements – amplify risk of hyper‑kalaemia.
• Lithium – ACE inhibition can raise lithium levels, necessitating dose adjustment or close monitoring.
• Other antihypertensives (β‑blockers, calcium‑channel blockers) – additive blood‑pressure lowering; dose titration may be required.

Patients should disclose all concurrent medicines, including over‑the‑counter products and herbal supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Usual starting dose for most adults is one tablet containing 10 mg lisinopril + 12.5 mg hydrochlorothiazide, taken once daily in the morning.
• Dose titration may be increased to 20 mg/12.5 mg or 40 mg/12.5 mg after 2–4 weeks if blood‑pressure targets are not met and the patient tolerates the medication.
• Renal or hepatic impairment – consider starting at the lowest dose and extending the interval between dose adjustments.

Missed dose: If a dose is forgotten and the scheduled time is still > 12 hours away, skip the missed dose and resume the regular once‑daily schedule. Do not double‑dose.

Overdose: Symptoms may include profound hypotension, dizziness, fainting, or electrolyte disturbances. Immediate medical attention is required. Management is largely supportive, with attention to blood‑pressure monitoring, intravenous fluids if needed, and correction of electrolyte imbalances.

Precautions:

• Take the tablet with a full glass of water, preferably in the morning to avoid nocturnal diuresis.
• Limit alcohol intake, as it can exacerbate hypotension.
• Avoid excessive salt intake, which counteracts the diuretic effect.
• Regularly monitor blood pressure, serum electrolytes, renal function, and urine output, especially during the first few weeks of therapy.

FAQ

• Is Zestoretic available in multiple strengths in the UK?
  Yes, Zestoretic is marketed in tablets containing 10 mg lisinopril + 12.5 mg hydrochlorothiazide, 20 mg + 12.5 mg, and 40 mg + 12.5 mg. The strength is selected based on individual blood‑pressure response and tolerability.

• Can Zestoretic be stored in a kitchen cabinet?
  The tablets should be kept at controlled room temperature (15‑25 °C), protected from moisture, light, and heat. A kitchen cabinet is acceptable if it is not near the stove or a sink where humidity could be high.

• What does the blister pack of Zestoretic look like?
  Each blister pack contains 28 or 30 tablets, depending on the packaging batch. The tablet is round, film‑coated, and color‑coded according to strength (e.g., white for 10 mg/12.5 mg, pink for 20 mg/12.5 mg, and blue for 40 mg/12.5 mg).

• Are there any special considerations when traveling abroad with Zestoretic?
  Carry the medication in its original packaging with a copy of the prescription or a doctor’s note, as some countries require documentation for ACE inhibitors. Keep the tablets in your hand luggage to avoid temperature extremes in the cargo hold.

• Does Zestoretic contain any lactose or gluten?
  In the UK formulation, lactose is listed as an inactive ingredient, while gluten is not present. Patients with severe lactose intolerance should discuss alternatives with their clinician.

• How does Zestoretic differ from taking lisinopril and hydrochlorothiazide separately?
  The fixed‑dose tablet reduces pill burden, improves adherence, and provides a precisely calibrated ratio of the two drugs, which has been shown to produce more consistent blood‑pressure control than separate tablets taken at different times.

• Can Zestoretic affect routine drug testing at work?
  No, the active ingredients are not screened for in standard occupational drug‑testing panels. However, the presence of diuretics may be noted in specialized electrolyte panels if requested.

• What historical trial established the benefit of combining an ACE inhibitor with a thiazide diuretic?
  The ACCOMPLISH trial (2008) demonstrated that an ACE inhibitor plus a thiazide diuretic achieved greater reductions in cardiovascular events compared with an ACE inhibitor plus a calcium‑channel blocker in high‑risk hypertensive patients.

• Is there a difference between the EU and US formulations of Zestoretic?
  The European version adheres to the EU Pharmacopoeia for tablet hardness and dissolution, while the US version follows the United States Pharmacopeia (USP) standards. Both contain the same active amounts but may have minor excipient variations.

• Does Zestoretic have a known impact on athletic performance?
  While the medication lowers blood pressure, it can also reduce plasma volume due to its diuretic effect, potentially leading to decreased endurance performance in high‑intensity activities if not managed with adequate hydration.
