Generic Indapamide

Introduction

Indindapamide is a thiazide‑like diuretic used principally to lower blood pressure and to reduce fluid accumulation in conditions such as hypertension and mild‑to‑moderate oedema. In the United Kingdom it is classified within the Blood Pressure and Diuretics groups of medicines. The active compound, indapamide, exerts a dual action that combines diuresis with peripheral vasodilation, offering an effective oral option for people whose blood‑pressure targets are not achieved with monotherapy. It is also occasionally prescribed off‑label for certain cases of chronic heart failure where fluid overload is a concern.

What is Indindapamide?

Indindapamide is a synthetic sulfonamide derivative developed in the early 197s by Hoechst AG (now part of Sanofi). It is marketed worldwide under several brand names, the most recognised being Lozol, Moduret, and Natrilix.

Indindapamide is the generic version of these brand‑name products, containing the same active compound indapamide. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

The medication is supplied as film‑coated tablets of 1.5 mg and 2.5 mg strengths, formulated for oral administration. It is approved by the Medicines and Healthcare products Regulatory Agency (MHRA) for use in the UK.

How Indindapamide Works

Indindapamide belongs to the class of thiazide‑like diuretics, but its pharmacology differs from classic thiazides such as hydrochlorothiazide. The drug inhibits the sodium‑chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption. This leads to increased urinary excretion of sodium, chloride, and water, lowering extracellular fluid volume.

Concurrently, indandapamide opens calcium‑activated potassium channels in vascular smooth muscle, producing a modest but sustained vasodilatory effect. The combination of modest diuresis and direct vasodilation reduces both preload and peripheral resistance, thereby lowering systemic arterial pressure.

Pharmacokinetic data show a rapid oral absorption (peak plasma concentration within 2–4 hours), a half‑life of roughly 14 hours, and predominant renal excretion. The prolonged half‑life supports once‑daily dosing for most adult patients.

Conditions Treated with Indindapamide

• Essential (primary) hypertension – Indindapamide is listed in the UK NICE hypertension guideline as a first‑line or add‑on therapy for patients requiring further blood‑pressure control.
• Mild to moderate peripheral oedema – The diuretic effect helps to remove excess interstitial fluid in conditions such as chronic venous insufficiency or medication‑induced fluid retention.
• Chronic heart failure (NYHA class II‑III) – Although not a primary heart‑failure medication, indandapamide may be added to standard therapy to improve symptom control through additional fluid removal.

In the UK, hypertension affects roughly 1 in 5 adults, and appropriate treatment reduces the risk of stroke, myocardial infarction, and renal disease. Indindapamide’s combined diuretic and vasodilatory actions make it a useful option when monotherapy is insufficient.

Who is Indindapamide For?

• Adults with newly diagnosed hypertension who are intolerant of, or have contraindications to, other thiazide diuretics (e.g., severe hypokalaemia).
• Patients already receiving an ACE inhibitor, ARB, or calcium‑channel blocker who need an additional antihypertensive agent to reach NICE‑recommended targets (<140/90 mmHg, or <130/80 mmHg for high‑risk groups).
• Individuals with fluid retention secondary to chronic venous disease or early‑stage heart failure, where a low‑dose diuretic can improve symptoms without causing marked electrolyte loss.

Indindapamide is not appropriate for patients with anuria, severe renal impairment (eGFR < 30 mL/min/1.73 m²), known hypersensitivity to sulfonamides, or uncontrolled gout, as the drug can precipitate uric acid accumulation. Pregnant or lactating women should only use the medication if the benefits clearly outweigh potential risks, under specialist supervision.

Risks, Side Effects, and Interactions

Common

• Electrolyte disturbances – mild hypokalaemia, hyponatraemia, or hypomagnesemia.
• Transient increase in serum uric acid – may precipitate gout attacks.
• Headache or dizziness – related to blood‑pressure reduction, especially after the first dose.

Rare

• Photosensitivity – skin rash or sun‑burn‑like reactions after prolonged UV exposure.
• Pancreatitis – isolated case reports; monitor for severe abdominal pain.

Serious

• Severe electrolyte imbalance – profound hypokalaemia or hyponatraemia leading to cardiac arrhythmia or seizures.
• Acute renal failure – especially in patients with pre‑existing renal disease or concurrent use of nephrotoxic drugs.
• Hypersensitivity reactions – including Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Clinically Relevant Drug–Drug Interactions

• Potassium‑sparing diuretics (e.g., spironolactone, amiloride) – may increase the risk of hyperkalaemia.
• Lithium – indandapamide reduces lithium clearance, raising the risk of lithium toxicity.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – can blunt the antihypertensive effect and worsen renal function.
• ACE inhibitors/ARBs – combined use may potentiate renal impairment and hyperkalaemia; monitor renal function and electrolytes regularly.

Patients should inform health‑care professionals of all medicines, over‑the‑counter products, and herbal supplements they are taking.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dose for hypertension: 1.5 mg tablet taken once daily in the morning. For oedema, the dose may be increased to 2.5 mg after clinician review.
• Renal impairment adjustment: In patients with eGFR 30‑50 mL/min/1.73 m², a reduced dose of 1.5 mg is advised; avoid use when eGFR < 30 mL/min/1.73 m².
• Missed dose: Take the missed tablet as soon as remembered unless it is within 12 hours of the next scheduled dose. In that case, skip the missed dose and continue with the regular schedule. Do not double‑dose.
• Overdose: Symptoms may include severe dehydration, electrolyte disturbances, and low blood pressure. Seek urgent medical attention. Management is supportive, focusing on fluid and electrolyte replacement and monitoring renal function.

Practical precautions – Indindapamide may increase the effect of alcohol on blood pressure; moderate consumption is advisable. The drug should be taken with food or a full glass of water to minimise gastrointestinal irritation. Regular monitoring of blood pressure, renal function, and serum electrolytes is recommended, especially after dose changes.

FAQ

• Is indandapamide available in both brand‑name and generic forms in the UK?
  Yes. The medication is marketed under several brand names such as Lozol, Moduret, and Natrilix, while generic versions contain the identical active compound indandapamide and are generally less expensive.

• What should I do with indandapamide tablets if I travel abroad?
  Keep the tablets in their original packaging, store them at room temperature away from excessive heat or humidity, and carry them in hand luggage to avoid temperature fluctuations in checked baggage.

• Does indandapamide require any special storage conditions?
  The tablets should be stored in a dry place at a temperature between 15 °C and 30 °C. Do not refrigerate or expose them to direct sunlight, as moisture can degrade the film coating.

• Are there any inactive ingredients that might cause allergies?
  Common excipients include lactose, microcrystalline cellulose, and magnesium stearate. Patients with known lactose intolerance or hypersensitivity to these substances should discuss alternatives with a health professional.

• Can indandapamide be imported for personal use in the UK?
  Personal import of up to a three‑month supply of a prescription‑only medication is permitted under UK regulations, provided the product is obtained from a licensed overseas pharmacy and the import is for personal, non‑commercial use.

• Do certain ethnic groups have different safety warnings for indandapamide?
  Studies suggest that individuals of Asian descent may experience a slightly higher incidence of electrolyte disturbances, so clinicians often monitor serum potassium and sodium more closely in these patients.

• How does indandapamide compare with older thiazide diuretics like hydrochlorothiazide?
  Indandapamide has a longer half‑life and a milder impact on blood‑potassium levels, making it less likely to cause hypokalaemia. Its vasodilatory component also contributes to better blood‑pressure reduction in some patients.

• Is there any evidence that indandapamide reduces cardiovascular events?
  Large‑scale outcome trials, such as the HYVET (Hypertension in the Very Elderly Trial), demonstrated that indandapamide‑based therapy lowered the risk of stroke and heart failure hospitalization in elderly hypertensive patients.

• Can indandapamide be taken with over‑the‑counter antihistamines?
  Most antihistamines do not interact clinically with indandapamide. However, sedating antihistamines may exacerbate dizziness caused by blood‑pressure lowering, so patients should be cautious when standing up quickly.

• What are the differences in tablet appearance between regions?
  In the EU, the 1.5 mg tablet is typically white and round, while the 2.5 mg tablet is blue and oval. In the US, the same strengths may be pink (1.5 mg) and green (2.5 mg). The colour coding helps avoid dosage errors.

• Does indandapamide have any impact on drug testing for athletes?
  Indandapamide is not listed on the World Anti‑Doping Agency (WADA) prohibited list. However, its diuretic effect could be considered a masking agent in some sports, so athletes should disclose its use to relevant governing bodies.

• Is there a risk of indandapamide causing dehydration during hot weather?
  Because the drug promotes fluid loss, patients exercising or working in high temperatures should maintain adequate hydration and monitor for signs of dizziness or excessive thirst.

• Can indandapamide be crushed or split for dose adjustment?
  The film coating is designed for controlled release; crushing may alter absorption and increase the risk of side effects. Tablet splitting is permissible only for the 2.5 mg strength if a lower dose is required, using a proper tablet‑splitter.

• How long does it take for blood pressure to stabilise after starting indandapamide?
  Blood‑pressure reduction can be observed within 2 weeks, but full therapeutic effect is usually achieved after 4–6 weeks of consistent daily dosing.
