Generic Acetazolamide Information

Introduction

Acetazolamide is a carbon‑dioxide‑binding diuretic that serves as a cornerstone in several clinical specialties across the United Kingdom. Its principal action is a reversible inhibition of the enzyme carbonic anhydrase, leading to altered tubular re‑absorption of sodium, bicarbonate, and water. The drug is listed under the British National Formulary (BNF) as a diuretic and is prescribed for conditions such as glaucoma, certain forms of epilepsy, and altitude‑related hypoxia. Although several manufacturers produce branded preparations, the active compound remains Acetazolamide. The molecule also finds secondary uses in metabolic alkalosis, certain types of renal tubular acidosis, and as an adjunct in the management of some respiratory disorders.

What is Acetazolamide?

Acetazolamide is the generic version of Diamox, a long‑standing brand name that contains the same active compound, Acetazolamide. The drug belongs to the sulfonamide class of carbonic anhydrase inhibitors and is administered systemically in tablet or injectible form. First introduced in the 195s by the pharmaceutical company Barbosa Laboratories (historical reference), it has since been marketed worldwide by multiple reputable suppliers. Our online pharmacy provides this generic alternative as a cost‑effective treatment option that matches the therapeutic quality of the original branded product.

How Acetazolamide Works

Carbonic anhydrase is an enzyme that catalyses the rapid conversion of carbon dioxide and water into bicarbonate and protons. By binding to the zinc ion at the enzyme’s active site, Acetazolamide reduces the formation of bicarbonate in the proximal renal tubule. The downstream effects are:

• Reduced bicarbonate re‑absorption → increased urinary excretion of bicarbonate, sodium, and water.
• Mild metabolic acidosis → stimulates peripheral chemoreceptors, lowering cerebral and intra‑ocular pressure in glaucoma, and enhancing ventilation in patients at high altitude.
• Altered electrolyte balance → the induced diuresis is modest compared with loop diuretics, making it useful when a milder fluid shift is desired.

Pharmacokinetic data from the UK Medicines and Healthcare products Regulatory Agency (MHRA) indicate an oral onset of action within 1–2 hours, a plasma half‑life of 10–15 hours, and renal excretion of unchanged drug. Steady‑state concentrations are achieved after 3–5 days of regular dosing.

Conditions Treated with Acetazolamide

Glaucoma (Open‑Angle)

Elevated intra‑ocular pressure (IOP) is a primary risk factor for optic‑nerve damage. By decreasing bicarbonate‑driven aqueous humour production, Acetazolamide lowers IOP, complementing topical therapies. In the UK, approximately 3% of adults (>40 years) have glaucoma, and oral carbonic anhydrase inhibition is a recognised adjuvant.

Epilepsy (Repetitive Myoclonic or Focal Seizures)

Acetazolamide reduces neuronal excitability through systemic acidosis and altered ion transport. Clinical trials in the UK have demonstrated seizure frequency reduction in drug‑resistant focal epilepsy when added to conventional antiepileptics.

Altitude‑Related Illness

Travelers to elevations >2 500 m frequently develop acute mountain sickness (AMS). The drug’s stimulation of ventilation via mild metabolic acidosis improves oxygenation, decreasing AMS scores in controlled studies conducted on the Scottish Highlands.

Metabolic Alkalosis and Renal Tubular Acidosis Type 2

In conditions where renal bicarbonate re‑absorption is excessive, Acetazolamide restores acid–base balance, reducing the need for aggressive electrolyte replacement.

Idiopathic Intracranial Hypertension

By lowering CSF production through reduced bicarbonate transport, the medication can lessen headache intensity and papilloedema, though it is adjunctive rather than first‑line.

Primary Candidates for Acetazolamide Therapy

• Adults with newly diagnosed open‑angle glaucoma requiring an oral adjunct to topical agents.
• Patients experiencing focal or myoclonic seizures who have not responded adequately to standard antiepileptic drugs.
• Individuals planning rapid ascent to high‑altitude locations (e.g., hiking the Scottish Highlands, skiing in the Alps) who are at risk of AMS.
• Those with persistent metabolic alkalosis where fluid and electrolyte replacement alone fails to correct pH.
• Persons with idiopathic intracranial hypertension presenting with visual symptoms or refractory headaches.

Acetazolamide may be unsuitable for patients with severe hepatic impairment, known sulfonamide hypersensitivity, or those taking concomitant drugs that raise the risk of hypokalaemia (e.g., loop diuretics, high‑dose corticosteroids). Contra‑indications also include uncontrolled diabetes mellitus type 1, advanced chronic kidney disease (eGFR < 15 mL/min/1.73 m²), and pregnancy.

Risks, Side Effects, and Interactions

Common adverse events

• Paraesthesia or tingling in the lips and fingers – often reversible after dose reduction.
• Taste disturbance (metallic or salty) – usually mild and transient.
• Mild metabolic acidosis (elevated serum lactate) – may cause fatigue or deeper breathing.
• Gastro‑intestinal upset – nausea, loose stools, or abdominal discomfort.

Rare adverse events

• Allergic reactions – urticaria, angio‑oedema, or rash, particularly in patients with sulfonamide sensitivity.
• Hypokalaemia – significant potassium loss can precipitate muscle weakness; monitor electrolytes if combined with other diuretics.
• Hepatic dysfunction – isolated cases of elevated transaminases reported in long‑term therapy.

Serious adverse events

• Severe metabolic acidosis – may lead to coma in patients with underlying respiratory compromise.
• Life‑threatening anaphylaxis – immediate discontinuation and emergency care required.
• Bone marrow suppression – rare agranulocytosis or aplastic anaemia, necessitating complete blood count monitoring.

Clinically relevant drug–drug interactions

• Potassium‑depleting agents (e.g., furosemide, spironolactone) – increase risk of hypokalaemia.
• Barbiturates, salicylates, or other carbonic‑anhydrase‑inhibiting drugs – additive effect on acidosis.
• Lithium – acetazolamide reduces lithium re‑absorption, raising serum lithium concentrations and toxicity risk.
• Corticosteroids – may amplify electrolyte disturbances.
• Warfarin – potential increase in pro‑coagulant effect due to altered plasma protein binding; monitor INR.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing – 250 mg taken one to three times daily for most indications. Initiation often begins with 125 mg twice daily, titrating to the lowest effective dose.
• Missed dose – If more than 8 hours have elapsed, take the missed dose immediately unless it would result in a dosing interval of less than 4 hours. Otherwise, skip the dose and resume the regular schedule.
• Overdose – Acute ingestion of more than 4 g may cause profound metabolic acidosis, seizures, or respiratory depression. Seek urgent medical attention; treatment includes symptomatic support, sodium bicarbonate infusion, and electrolyte monitoring.
• Food and alcohol – Absorption is not markedly influenced by meals, but high‑salt diets may counteract diuretic efficiency. Alcohol can exacerbate CNS side effects; moderate consumption is advised.
• Comorbidities – Renal impairment demands dose reduction; hepatic dysfunction warrants caution and close monitoring of acid–base status.
