Generic Prevacid Information

Introduction

Prevacid, known internationally by its active ingredient lansoprazole, belongs to the Gastro Health group of medicines. It is a proton‑pump inhibitor (PPI) that reduces gastric acid production, providing relief for a range of acid‑related disorders. In the United Kingdom, Prevacid is prescribed by clinicians and dispensed by pharmacies for conditions such as gastro‑oesophageal reflux disease (GORD), peptic ulcer disease and the prevention of non‑steroidal anti‑inflammatory drug (NSAID)‑induced ulcers. The drug is manufactured by Takeda Pharmaceuticals and is regulated by the UK Medicines and Healthcare products Regulatory Agency (MHRA).

What is Prevacid?

Prevacid is the generic version of the original brand Prevacid®, containing the same active compound lansoprazole. Other well‑known lansoprazole brand names include Lanzor, Lansox and Prevacid® in different markets. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, delivering the same therapeutic effect at a price close to the manufacturer’s cost.

Lansoprazole is classified as a proton‑pump inhibitor. It was first approved for clinical use in the early 199s and has since become a staple in the management of acid‑related gastrointestinal diseases. In the UK, it is listed in the British National Formulary (BNF) and follows the same prescribing guidelines as the brand‑named product.

How Prevacid Works

Lansoprazole acts on the gastric parietal cell’s H⁺/K⁺‑ATPase enzyme, commonly called the “proton pump.” By forming a covalent disulfide bond with cysteine residues on the pump, lansoprazole irreversibly blocks the final step of acid secretion. This inhibition reduces both basal and stimulated gastric acid output for up to 24 hours after a single dose.

Key pharmacokinetic points:

• Onset of action: Acid suppression begins within 1 hour of ingestion, reaching maximal effect after 2–4 hours.
• Duration: The effect persists for about 24 hours, allowing once‑daily dosing for most indications.
• Metabolism and clearance: Lansoprazole is metabolised primarily by hepatic CYP2C19 and CYP3A4 enzymes; its metabolites are eliminated renally. Genetic polymorphisms in CYP2C19 can affect plasma levels, which is why dose adjustments may be required in poor metabolizers.

The result is an increased gastric pH that promotes ulcer healing, reduces reflux symptoms, and protects the gastrointestinal lining from NSAID‑induced injury.

Conditions Treated with Prevacid

• Gastro‑oesophageal reflux disease (GORD):
  Prevalence in the UK is estimated at 15‑20 % of the adult population. Acid suppression relieves heartburn, regurgitation and oesophagitis, improving quality of life and preventing complications such as Barrett’s oesophagus.

• Erosive oesophagitis:
  Endoscopically confirmed mucosal erosion benefits from rapid acid control, allowing mucosal repair within weeks of therapy.

• Peptic ulcer disease (duodenal and gastric ulcers):
  By maintaining a higher gastric pH, lansoprazole supports ulcer healing and reduces the risk of recurrence.

• Helicobacter pylori eradication (as part of triple therapy):
  Lansoprazole enhances the efficacy of antibiotics by creating a less acidic environment, which improves bacterial susceptibility.

• NSAID‑induced ulcer prophylaxis:
  Long‑term NSAID users, especially those over 60 years or with a history of ulcer disease, receive protective therapy to prevent gastrointestinal bleeding.

• Zollinger‑Ellison syndrome (rare):
  Although uncommon, high‑dose lansoprazole can control the severe hyper‑acidity seen in this endocrine tumour.

Each indication is supported by NICE technology appraisal guidance (TA150) and the BNF, which recommend lansoprazole as first‑line PPI therapy for most acid‑related conditions.

Who is Prevacid For?

• Adults with frequent heartburn or reflux symptoms that persist despite lifestyle modification.
• Patients diagnosed with erosive oesophagitis confirmed by endoscopy.
• Individuals with confirmed duodenal or gastric ulcers, especially when Helicobacter pylori infection is present.
• Long‑term NSAID users who have risk factors for gastrointestinal bleeding (age > 60, prior ulcer, concurrent anticoagulant therapy).
• Patients requiring H. pylori eradication regimens, where lansoprazole forms part of the triple‑therapy protocol.

Contraindications and cautions

• Known hypersensitivity to lansoprazole or any excipients in the tablet.
• Severe hepatic impairment (Child‑Pugh class C) – dose reduction or alternative therapy may be needed.
• Pregnancy and lactation: Lansoprazole is classified as Category B; it should only be used when clearly indicated.

Patients with a history of Clostridioides difficile infection, osteoporosis, or low magnesium levels should discuss risks with a clinician before initiating therapy, as long‑term PPI use has been associated with these conditions in observational studies.

Risks, Side Effects, and Interactions

Common

• Headache
• Diarrhoea or constipation
• Abdominal pain or flatulence
• Nausea
• Dry mouth

These events are usually mild, transient and resolve without the need for discontinuation.

Rare

• Cutaneous reactions (rash, pruritus, photosensitivity)
• Elevated liver enzymes (transient ALT/AST rise)
• Hypomagnesemia (particularly with prolonged therapy > 12 months)

Patients experiencing unexplained skin eruptions or persistent gastrointestinal symptoms should seek medical advice.

Serious

• Clostridioides difficile‑associated diarrhoea – PPIs may alter gut flora, increasing infection risk.
• Severe allergic reactions (anaphylaxis, angio‑oedema) – immediate medical attention required.
• Fracture risk – long‑term high‑dose use has been linked to reduced bone mineral density, especially in post‑menopausal women and older adults.

Drug‑drug interactions

• Antiplatelet agents (e.g., clopidogrel): Lansoprazole can reduce the activation of clopidogrel, potentially diminishing antiplatelet effect. Consider alternative PPIs (e.g., pantoprazole) when dual therapy is required.
• Antiretrovirals (e.g., atazanavir, nelfinavir): Reduced plasma concentrations may occur, compromising HIV therapy.
• Warfarin: Enhanced anticoagulant effect has been reported; monitor INR more closely.
• Ketoconazole, Itraconazole, Voriconazole: Absorption of these antifungals is pH‑dependent; co‑administration may decrease their efficacy.

Patients should provide a full medication list, including over‑the‑counter drugs and herbal supplements, to avoid adverse interactions.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing (tablet form, oral):

  • GORD, erosive oesophagitis, ulcer prophylaxis: 30 mg once daily.
  • H. pylori eradication (triple therapy): 30 mg twice daily for 7–14 days.
  • Zollinger‑Ellison syndrome: 60 mg once daily, may be increased up to 90 mg based on acid output measurements.

• Administration: Swallow whole with a glass of water, preferably 30 minutes before a meal. Food does not significantly affect absorption, but taking on an empty stomach enhances onset.

• Missed dose: Take the missed tablet as soon as remembered unless it is near the time of the next scheduled dose. In that case, skip the missed tablet and continue with the regular schedule; do not double dose.

• Overdose: Acute overdose of lansoprazole is unlikely to be life‑threatening. Symptoms may include mild nausea, vomiting or dizziness. Seek urgent medical assessment if large amounts are taken accidentally.

• Precautions: Chronic alcohol intake may exacerbate gastritis; limit consumption while on therapy. Renal impairment does not require dose adjustment, but hepatic dysfunction may.
