Indications & Clinical Uses

  • Nadexam is a fixed‑dose combination that targets the hypertension pathway to achieve blood‑pressure control.
  • Hypertension: reduces elevated systolic and diastolic pressure in adults with essential hypertension.
  • Essential hypertension: provides additional control when monotherapy is insufficient.
  • Isolated systolic hypertension: helps achieve target systolic values in older patients.

How It Works

  • Indapamide inhibits sodium reabsorption in the distal renal tubule, promoting diuresis and decreasing plasma volume. Amlodipine besilate blocks L‑type calcium channels in vascular smooth muscle, causing arterial vasodilation. The complementary actions lower systemic vascular resistance and cardiac preload, resulting in a net reduction of arterial blood pressure.

Side Effects

Nadexam may cause a range of adverse reactions, which are grouped by frequency.

Common Side Effects

  • Dizziness or light‑headedness
  • Headache
  • Peripheral edema, especially of the ankles
  • Flushing or warmth sensation
  • Fatigue or tiredness
  • Nausea or mild gastrointestinal upset

Serious or Rare Side Effects

  • Severe hypotension leading to fainting
  • Electrolyte disturbances such as low potassium
  • Acute renal dysfunction or worsening of existing kidney disease
  • Angioedema or severe swelling of face, lips, or throat
  • Hepatic injury manifested by jaundice or elevated liver enzymes
  • Severe skin reactions, including Stevens‑Johnson syndrome

Precautions & Warnings

  • Before initiating therapy, clinicians should evaluate patient‑specific factors and monitor for potential complications.
  • Monitor blood pressure regularly: adjust therapy if target levels are not reached.
  • Assess renal function: check serum creatinine and eGFR before and during treatment.
  • Check electrolytes: especially potassium and sodium levels.
  • Use caution in severe hepatic impairment: dose adjustment may be required.
  • Elderly patients: start at lower doses and monitor for orthostatic hypotension.
  • Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Avoid Interactions

Nadexam can interact with several medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

  • Lithium: risk of lithium toxicity increases.
  • NSAIDs (e.g., ibuprofen, naproxen): may blunt diuretic effect and raise renal risk.
  • Potassium‑sparing diuretics (e.g., spironolactone): can cause hyperkalaemia.
  • Strong CYP3A4 inhibitors (e.g., clarithromycin, itraconazole): raise amlodipine plasma concentrations.

Moderate Interactions (Monitor Closely)

  • ACE inhibitors or ARBs: additive blood‑pressure lowering effect; monitor for hypotension.
  • Beta‑blockers: may enhance hypotensive response.
  • Digoxin: amlodipine can increase digoxin levels; watch for toxicity.

Frequently Asked Questions

Nadexam is prescribed to lower high blood pressure in adults. It combines a thiazide‑like diuretic (indapamide) with a calcium‑channel blocker (amlodipine) to provide complementary blood‑pressure reduction, especially when single‑agent therapy does not achieve target levels.

Indapamide promotes the excretion of sodium and water by inhibiting reabsorption in the kidney’s distal tubule, which reduces plasma volume. Amlodipine blocks L‑type calcium channels in arterial smooth muscle, causing vasodilation. Together they lower both cardiac output and peripheral resistance, resulting in an overall drop in arterial pressure.

The specific dose of Nadexam is determined by the prescribing clinician based on the patient’s blood‑pressure profile, age, renal function and other medical factors. Dosage adjustments are made to achieve optimal control while minimizing side effects.

Safety data for Nadexam in pregnancy and lactation are limited. The product should only be used if the potential benefit justifies the potential risk to the fetus or infant. Women who are pregnant, planning pregnancy, or breastfeeding should discuss alternatives with their healthcare provider.

To place an order, submit an enquiry on the Nadexam product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and necessary import documentation.

Compared with single‑agent diuretics or calcium‑channel blockers, Nadexam offers dual mechanisms in one tablet, which can improve blood‑pressure control and simplify regimens. It may be preferred when monotherapy fails to reach targets, but clinicians consider patient‑specific factors such as renal function, electrolyte balance and drug‑interaction potential.

Store Nadexam at ambient temperature, below 25 °C, in the original blister or bottle. Keep the product away from moisture, heat and direct sunlight. Do not use if the packaging is damaged or the tablets appear discoloured.

Nadexam is taken orally, usually once daily, with or without food. Swallow the tablet whole with a full glass of water. Patients should follow the dosing schedule prescribed by their clinician and not alter the timing without medical advice.

Serious adverse events include severe hypotension, electrolyte disturbances (especially low potassium), acute kidney injury, angioedema, and rare severe skin reactions such as Stevens‑Johnson syndrome. Patients should seek immediate medical attention if they experience swelling of the face or throat, sudden weakness, or a rash that spreads.

Nadexam is contraindicated in patients with known hypersensitivity to indapamide, amlodipine, or any component of the formulation. It should also be avoided in individuals with severe hepatic impairment, uncorrected electrolyte abnormalities, or those taking prohibited medications that may cause dangerous interactions.
