Generic Candesartan Information

Introduction

Candesartan is an oral antihypertensive medication approved for the treatment of high blood pressure and chronic heart failure. It belongs to the angiotensin II receptor blocker (ARB) class and is listed on the NHS formulary for adults in the United Kingdom. The active compound, candesartan, is supplied both as a stand‑alone generic product and under the well‑known brand name Atacand (Novartis). In addition to its primary role in controlling blood pressure, candesartan is used to reduce cardiovascular mortality in patients with left‑ventricular systolic dysfunction.

What is Candesartan?

Candesartan is the generic version of the original brand Atacand, containing the same active compound, candesartan. Our online pharmacy provides this generic alternative as a cost‑effective treatment option. The drug is marketed as candesartan cilexetil, a pro‑drug that is rapidly hydrolysed in the gastrointestinal tract to the active candesartan. It is classified as an angiotensin II receptor blocker (ARB) and was first developed by Takeda Pharmaceutical Company before being licensed to Novartis for commercial distribution. In the UK, the Medicines and Healthcare products Regulatory Agency (MHRA) authorises its use for hypertension and heart failure, and it is listed in the National Institute for Health and Care Excellence (NICE) guidance NG136.

How Candesartan Works

Candesartan blocks the binding of angiotensin II to the AT1 receptor on vascular smooth‑muscle cells, adrenal glands, and the renal tubules. By preventing this interaction, the drug inhibits the vasoconstrictive, aldosterone‑secreting, and sympathetic‑stimulating effects of angiotensin II. The result is arterial vasodilation, reduced sodium and water reabsorption, and a modest decrease in sympathetic tone. Clinically this translates into lower systemic vascular resistance and a reduction in blood pressure, usually evident within 2 weeks of therapy. In patients with heart failure, the same mechanism reduces afterload and ventricular remodeling, thereby improving cardiac output and survival. Candesartan has a bioavailability of approximately 15 % for the pro‑drug, an elimination half‑life of 9 hours for the active moiety, and is excreted primarily unchanged by the kidneys (≈30 %) and the liver (≈70 %).

Conditions Treated with Candesartan

• Essential (primary) hypertension – The most common indication. In the UK, roughly one in three adults has elevated blood pressure, and ARBs are a first‑line option when ACE inhibitors are not tolerated.
• Chronic heart failure (NYHA class II–IV) with reduced ejection fraction – Large‑scale trials (e.g., CHARM‑Overall) demonstrated a 15 % relative risk reduction in cardiovascular death and hospitalisation when candesartan was added to standard therapy.
• Left‑ventricular systolic dysfunction post‑myocardial infarction – NICE recommends ARBs for patients who remain symptomatic despite optimal ACE‑inhibitor therapy or who develop cough.

These indications are supported by robust randomised controlled trials and are incorporated into UK clinical pathways.

Who is Candesartan For?

Candesartan is appropriate for adult patients who require long‑term blood‑pressure control, particularly when:

• ACE‑inhibitor therapy has caused a persistent dry cough or angio‑edema.
• Co‑existing chronic kidney disease (CKD) stage 1–3 is present, provided serum potassium is monitored.
• Heart failure with reduced ejection fraction is diagnosed, and the patient is on stable background therapy (β‑blocker, mineral‑ocorticoid receptor antagonist).

Contra‑indications include pregnancy, breastfeeding, severe hepatic impairment, and known hypersensitivity to candesartan or any excipients. Caution is advised in patients with bilateral renal artery stenosis, serum potassium >5. mmol/L, or those taking potassium‑sparing diuretics.

Risks, Side Effects, and Interactions

Common

• Headache – Often mild and transient during dose titration.
• Dizziness or light‑headedness – Related to orthostatic hypotension, especially after the first dose.
• Fatigue – May improve as blood pressure stabilises.
• Upper respiratory tract infection – Not drug‑specific but frequently reported.

Rare

• Hyperkalaemia – More likely in patients with CKD or when combined with potassium‑rich diets or supplements.
• Renal function decline – Small rise in serum creatinine (≤30 %) is expected; larger increases warrant discontinuation.
• Angio‑edema – Very uncommon, but requires immediate medical attention.

Serious

• Severe hypotension – Risk is heightened in volume‑depleted patients, those on high‑dose diuretics, or elderly individuals.
• Acute renal failure – May occur in bilateral renal artery stenosis or rapid decline in renal perfusion.
• Liver injury – Extremely rare; monitor for jaundice or unexplained transaminase elevation.

Drug–Drug Interactions

• Potassium‑sparing diuretics (e.g., spironolactone, amiloride) – Potentiate hyperkalaemia.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – May blunt antihypertensive effect and increase renal risk.
• Lithium – Candesartan can raise lithium levels; therapeutic drug monitoring is advised.
• Dual RAS blockade (ACE inhibitor + ARB) – Increases risk of hypotension, hyperkalaemia, and renal impairment; generally discouraged.

Patients should disclose all over‑the‑counter medicines, supplements, and herbal products before initiating candesartan.

Practical Use: Dosing, Missed Dose, Overdose

• Initial dose for hypertension – 4 mg once daily; may be increased after 2 weeks to 8 mg, 16 mg or 32 mg according to blood‑pressure response.
• Heart‑failure dosing – Start with 4 mg once daily; titrate to 16 mg once daily as tolerated, with the maximum recommended dose of 32 mg.
• Renal impairment – For eGFR 15–30 mL/min/1.73 m², initiate at 4 mg and consider a maximum of 8 mg daily; avoid use if eGFR < 15 mL/min/1.73 m².
• Missed dose – Take the forgotten tablet as soon as remembered unless it is near the time of the next scheduled dose. In that case, skip the missed dose and continue with the regular regimen; do not double‑dose.
• Overdose – Symptoms may include profound hypotension, syncope, and renal dysfunction. Immediate medical evaluation is essential; supportive care with intravenous fluids and vasopressors may be required. Activated charcoal is effective if presentation is within one hour of ingestion.

Practical precautions – Candesartan can be taken with or without food. Alcohol may amplify hypotensive effects and should be consumed cautiously. Regular monitoring of blood pressure, serum potassium, and renal function is recommended, particularly after dose adjustments.

FAQ

• Is Candesartan available in both brand‑name and generic forms in the UK?
  Yes, the medication is marketed as the brand‑name Atacand and also as a generic called candesartan cilexetil. The generic version contains the identical active ingredient and is usually less expensive, making it a common choice for NHS prescribing.

• What does a candesartan tablet look like?
  Generic candesartan tablets are typically white, round, and film‑coated, bearing a dosage imprint such as “4 mg” or “16 mg” on one side. Brand‑name Atacand tablets are also white, but they may feature a different imprint and a slightly convex shape.

• Does candesartan require refrigeration?
  No, candesartan should be stored at controlled room temperature, between 15 °C and 30 °C (59 °F–86 °F). It must be kept away from excessive moisture, direct sunlight, and sources of heat.

• Can I travel internationally with candesartan?
  Yes, candesartan can be taken while traveling. Carry the medication in its original packaging with a copy of the prescription or a doctor’s note, and be aware of any import limits for personal medication in the destination country.

• Are there any differences in formulation between Europe and the United States?
  European formulations use candesartan cilexetil as the pro‑drug, identical to the US product. However, certain inactive ingredients such as lactose or specific film‑coating polymers may vary between manufacturers, which can be relevant for patients with excipient sensitivities.

• How long is the shelf‑life of candesartan tablets?
  The typical shelf‑life is 24 months from the date of manufacture, provided the product remains sealed and stored under recommended conditions. The expiry date is printed on the blister pack.

• Will candesartan affect routine blood‑test results?
  Candesartan does not interfere with standard laboratory assays for glucose, lipids, or liver function. However, it can modestly increase serum creatinine and potassium, so clinicians usually repeat these parameters after starting therapy.

• Is candesartan safe for people of Asian descent?
  Clinical data indicate that candesartan’s efficacy and safety profile are consistent across ethnic groups, including Asian populations. Nevertheless, some guidelines suggest closer monitoring of potassium levels in patients with higher baseline dietary potassium intake.

• Can candesartan be taken with a high‑potassium diet?
  While a moderate potassium intake is acceptable, patients on candesartan should avoid excessive potassium‑rich foods (e.g., banana, orange juice, dried fruit) if they are also using potassium‑sparing diuretics or have impaired renal function, to minimise the risk of hyperkalaemia.

• What is the half‑life of the active metabolite?
  The active form of candesartan has an elimination half‑life of approximately 9 hours, allowing once‑daily dosing. Steady‑state concentrations are generally achieved after 3–4 days of regular therapy.
