Generic Aciphex Information

Introduction

Aciphex® (rabeprazole) is a prescription medication classified within the Gastro Health group. It is principally indicated for the management of acid‑related disorders such as gastro‑oesophageal reflux disease (GERD) and peptic ulcer disease. In Hong Kong, Aciphex is supplied by AstraZeneca and is registered with the Department of Health. The drug is also used off‑label for conditions requiring sustained suppression of gastric acid, for example, Zollinger‑Ellison syndrome.

What is Aciphex?

Aciphex contains the active compound rabeprazole, a proton pump inhibitor (PPI). It was developed by AstraZeneca and received regulatory approval in the United States in 1997, followed by approval in the European Union and many Asian jurisdictions, including Hong Kong. The product is marketed as a delayed‑release tablet that delivers rabeprazole to the acidic environment of the stomach.

How Aciphex Works

Rabeprazole inhibits the H⁺/K⁺‑ATPase enzyme (the gastric proton pump) located on the secretory surface of parietal cells. By forming a covalent disulfide bond with cysteine residues of the pump, rabeprazole blocks the final step of acid secretion, leading to a profound and prolonged increase in gastric pH. The onset of acid suppression generally occurs within 1 hour after oral intake, with maximal effect reached after 3‑4 days of once‑daily dosing. The drug is metabolised primarily by hepatic cytochrome P450 2C19 (CYP2C19) and to a lesser extent by CYP3A4, resulting in a plasma half‑life of approximately 1–2 hours; however, the functional inhibition of the proton pump persists for up to 24 hours because new pump synthesis is required for acid production to resume.

Conditions Treated with Aciphex

• Gastro‑oesophageal reflux disease (GERD). Persistent reflux of gastric contents causes esophageal mucosal injury; acid suppression promotes symptom relief and mucosal healing.
• Erosive oesophagitis. Endoscopically confirmed erosions respond to higher gastric pH, facilitating regeneration of the esophageal epithelium.
• Healing of duodenal and gastric ulcers. By reducing gastric acidity, Aciphex creates an environment conducive to ulcer repair and protects against re‑bleeding.
• Zollinger‑Ellison syndrome. This rare gastrin‑secreting tumour causes hyper‑secretion of acid; high‑dose PPI therapy is required for adequate control.

In Hong Kong, prevalence studies estimate that up to 15 % of adults experience weekly heartburn, making GERD a common indication for PPI therapy. Aciphex’s rapid onset and sustained suppression align with the therapeutic goals for these populations.

Patient Groups Most Likely to Benefit

• Adults with frequent heartburn or regurgitation (≥ twice weekly) unresponsive to lifestyle modification.
• Patients diagnosed with erosive oesophagitis (Los Angeles grades A–D) who require accelerated healing.
• Individuals on non‑steroidal anti‑inflammatory drugs (NSAIDs) who develop ulcerative complications.
• Patients with confirmed Zollinger‑Ellison syndrome requiring high‑dose acid suppression.

Aciphex is not recommended for patients with known hypersensitivity to rabeprazole or other PPIs, for those with severe hepatic impairment (Child‑Pugh C), or for pregnant women unless the benefit outweighs the risk after obstetric consultation.

Risks, Side Effects, and Interactions

Common

• Headache
• Diarrhoea or constipation
• Abdominal pain
• Nausea

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

Rare

• Raised serum aminotransferases (hepatic enzyme elevation)
• Skin rash or urticaria
• Myalgia

Patients experiencing persistent liver enzyme elevation should be evaluated for alternative therapy.

Serious

• Clostridioides difficile infection. Prolonged acid suppression can predispose to enteric infections.
• Pneumonia (including aspiration). Meta‑analyses suggest a modest increase in risk with long‑term PPI use.
• Fracture risk. Chronic suppression of calcium absorption may increase hip, wrist, and vertebral fracture incidence, particularly in patients >  years.
• Severe hypersensitivity (anaphylaxis). Immediate medical attention is required if symptoms such as swelling of the face, lips, or tongue occur.

Drug–Drug Interactions

• Clopidogrel. Rabeprazole may reduce the antiplatelet effect of clopidogrel via CYP2C19 inhibition; consider alternative PPIs (e.g., pantoprazole) if combined therapy is necessary.
• Warfarin. PPIs can enhance anticoagulant effect; monitor INR closely when initiating or discontinuing Aciphex.
• Antiretrovirals (e.g., atazanavir, nelfinavir). Increased gastric pH can reduce absorption, potentially compromising viral suppression.
• Methotrexate (high dose). Reduced renal clearance may occur; dose adjustment and monitoring are advisable.

Patients should disclose all concurrent medications, including over‑the‑counter products and herbal supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing for GERD: 20 mg once daily before a morning meal; treatment duration is usually 4‑8 weeks.
• Erosive oesophagitis: 20 mg once daily for 8 weeks; severe cases may require 40 mg daily.
• Zollingerison syndrome: initial dose of 40 mg twice daily, titrated to the lowest effective dose.

Missed dose: Take the missed tablet as soon as remembered unless it is close to the time of the next scheduled dose; do not double‑dose.

Overdose: Symptoms may include nausea, vomiting, and dizziness. Immediate medical evaluation is recommended; supportive care is the primary treatment.

Food and alcohol: Aciphex should be taken on an empty stomach (at least 30 minutes before breakfast) to optimise absorption. Moderate alcohol intake does not affect efficacy but excessive consumption may exacerbate gastric irritation.

Renal or hepatic impairment: No dosage adjustment is required for mild to moderate renal impairment. Patients with severe hepatic dysfunction should avoid use due to limited data on safety.

FAQ

• Is a prescription required to obtain Aciphex in Hong Kong?
  Yes, Aciphex is a prescription‑only medication under Hong Kong law. Our online pharmacy arranges a qualified prescriber’s review to issue a prescription before dispensing.

• Can Aciphex be stored in the refrigerator?
  No, Aciphex tablets should be kept at room temperature, away from moisture and direct sunlight. Refrigeration is unnecessary and may affect tablet integrity.

• How long can a patient safely continue Aciphex therapy?
  For most indications, a treatment course of 4‑8 weeks is sufficient. Long‑term maintenance therapy should be periodically reassessed by a physician, especially in patients over 65 years due to increased fracture and infection risks.

• Does Aciphex affect the absorption of vitamins or minerals?
  Prolonged acid suppression can reduce absorption of calcium, magnesium, and vitamin B12. Patients on chronic therapy may require monitoring and supplementation as advised by their healthcare provider.

• Are there any known differences between Aciphex formulations sold in the US, EU, and Asia?
  The core active ingredient (rabeprazole) and delayed‑release technology are consistent across regions. Excipients such as lactose or maize starch may vary slightly, but these differences do not alter clinical efficacy.

• Can Aciphex be used together with antacids?
  Antacids containing aluminum or magnesium may neutralise gastric acid and provide rapid relief, they can also reduce rabeprazole absorption if taken concurrently. It is advisable to separate antacid intake by at least 30 minutes after the Aciphex tablet.

• Is Aciphex safe for patients with hepatitis C undergoing antiviral therapy?
  While rabeprazole does not directly interact with most hepatitis C antivirals, the increased gastric pH can affect the bioavailability of certain protease inhibitors. Consultation with the treating hepatologist is recommended.

• What should a patient do if the Aciphex tablets arrive damaged or look counterfeit?
  Contact our customer service immediately. We will arrange for a replacement shipment or a full refund, and we cooperate with regulatory authorities to investigate any suspected counterfeit products.

• Does Aciphex have any known effect on blood pressure or heart rate?
  Rabeprazole does not have a direct pharmacological impact on cardiovascular parameters. However, indirect effects can arise from electrolyte disturbances (e.g., low magnesium) in long‑term use, which may influence cardiac rhythm.

• Can Aciphex be ordered for personal import without a local prescription?
  Personal import of prescription medicines into Hong Kong requires a valid prescription from a Hong Kong‑registered practitioner. Our online pharmacy’s prescription service complies with this regulation, ensuring legal importation.
