Voltapraz 20mg Tab

VOLTAPRAZ 20MG TABLET is a medication primarily used for managing conditions associated with excessive stomach acid production. It is manufactured by SUN PHARMA-SYGNUS DIV.

Name

• Brand Name: VOLTAPRAZ 20MG TAB
• Common Name (Active Ingredient): Vonoprazan

Composition

VOLTAPRAZ 20MG TABLET contains 20 mg of Vonoprazan as its active ingredient. Vonoprazan is a potassium-competitive acid blocker (P-CAB) that works by inhibiting the H+/K+-ATPase enzyme in the stomach's parietal cells, thereby reducing the amount of acid produced in the stomach. This mechanism provides a faster and more consistent control of gastric pH compared to traditional proton pump inhibitors (PPIs).

Uses

VOLTAPRAZ 20MG TABLET is prescribed for several gastrointestinal conditions:

• Stomach Ulcers: It accelerates the healing process of stomach ulcers and helps prevent their recurrence.
• Gastroesophageal Reflux Disease (GERD) and Acid Reflux: It reduces stomach acid to alleviate symptoms like heartburn and acid regurgitation, and aids in healing damage to the esophagus (reflux esophagitis).
• Erosive Esophagitis: Used to heal all grades of erosive esophagitis and relieve associated heartburn in adults.
• H. pylori Infection: When used in combination with antibiotics (such as clarithromycin and/or amoxicillin), it helps to eradicate Helicobacter pylori bacteria, which can cause stomach ulcers.
• Prevention of Ulcers: It can prevent the recurrence of gastric or duodenal ulcers, especially those caused by the use of low-dose aspirin or NSAIDs.

Dosage and Administration

Follow your doctor's instructions for dosage and duration. VOLTAPRAZ 20MG TABLET should be swallowed whole with water; do not chew, crush, or break the tablet. It can be taken with or without food, but some sources suggest taking it at the same time each day for optimal results, possibly in the morning. To prevent acid reflux, avoid lying down immediately after taking the medication.

Side Effects

Common side effects may include:

• Nausea
• Diarrhea
• Indigestion
• Bloating
• Stomach pain or inflammation
• High blood pressure
• Urinary tract infection
• Headache

Consult your doctor if any side effects persist or worsen.

Precautions

• Allergies: Do not take if you are allergic to Vonoprazan or any other ingredients.
• Pregnancy and Breastfeeding: Consult your doctor before use if you are pregnant, planning to conceive, or breastfeeding.
• Liver/Kidney Conditions: Use with caution in patients with liver impairment; dose adjustments may be necessary. Inform your doctor about any kidney or liver problems.
• Drug Interactions: Inform your healthcare provider about all medications, supplements, and herbals you are taking, as VOLTAPRAZ can interact with certain drugs (e.g., Rilpivirine, Nelfinavir, Atazanavir, iron salts, some antifungals).
• Lifestyle: Avoid alcohol, spicy foods, and caffeine, and refrain from smoking, as these can worsen symptoms or reduce medication effectiveness.
• Medical Conditions: Inform your doctor if you have a history of gastric malignancy, acute tubulointerstitial nephritis, Clostridioides difficile-associated diarrhea, osteopenia, osteoporosis, or low levels of magnesium, calcium, or potassium in your blood.
• Children: Safety and effectiveness have not been established in children.

Storage

Store VOLTAPRAZ 20MG TABLET at room temperature, in a cool and dry place, away from direct sunlight. Keep it out of the reach of children and pets.

VOLTAPRAZ 20MG TAB contains Vonoprazan, a medication used to reduce stomach acid. It belongs to a class of drugs known as potassium-competitive acid blockers (PCABs).

Here are some frequently asked questions about VOLTAPRAZ 20MG TAB:

What is VOLTAPRAZ 20MG TAB used for?

VOLTAPRAZ 20MG TAB (Vonoprazan) is used to treat various acid-related conditions of the stomach and esophagus. These include healing and maintenance of erosive esophagitis (damage to the esophagus from stomach acid), relief of heartburn associated with non-erosive gastroesophageal reflux disease (GERD), and healing of gastric and duodenal ulcers. It is also used in combination with antibiotics to treat Helicobacter pylori (H. pylori) infection and to prevent the recurrence of ulcers during ongoing use of NSAIDs (non-steroidal anti-inflammatory drugs) or low-dose aspirin.

How does VOLTAPRAZ 20MG TAB work?

Vonoprazan, the active ingredient, works as a potassium-competitive acid blocker (PCAB). It suppresses the production of stomach acid by inhibiting the H+, K+-ATPase enzyme system (also known as the proton pump) in the gastric parietal cells. Unlike traditional proton pump inhibitors (PPIs), Vonoprazan binds to the proton pump in a reversible and potassium-competitive manner and does not require activation by acid. This mechanism allows for rapid and sustained reduction of gastric acid secretion.

What is the usual dosage of VOLTAPRAZ 20MG TAB?

The dosage of VOLTAPRAZ 20MG TAB varies depending on the condition being treated:

• For healing of erosive esophagitis: Typically 20 mg once daily for 8 weeks.
• For maintenance of healed erosive esophagitis: Usually 10 mg once daily for up to 6 months.
• For relief of heartburn associated with non-erosive GERD: Generally 10 mg once daily for 4 weeks.
• For H. pylori eradication: 20 mg twice daily, in combination with specific antibiotics (e.g., amoxicillin and clarithromycin) for 14 days.
• For healing peptic ulcers: Usually 20 mg once daily. It's important to follow your doctor's specific instructions regarding dosage and duration.

What are the possible side effects of VOLTAPRAZ 20MG TAB?

Common side effects may include headache, diarrhea, nausea, abdominal pain, indigestion, constipation, dizziness, and bloating.

More serious, but rare, side effects can include:

• Severe allergic reactions (rash, itching, swelling of the face/lips/tongue/throat, trouble breathing).
• Kidney problems, such as acute tubulointerstitial nephritis (symptoms like changes in urination, fever, rash, joint pain).
• Low magnesium levels (hypomagnesemia), especially with long-term use (symptoms like muscle cramps, irregular heartbeat, tremors, seizures).
• Low vitamin B12 levels with long-term use (symptoms like unusual tiredness, nerve damage).
• Increased risk of bone fractures (hip, wrist, spine), particularly with long-term or high-dose use.
• Stomach growths (fundic gland polyps), typically benign, with long-term use.

Consult your doctor if you experience any severe or persistent side effects.

Is VOLTAPRAZ 20MG TAB safe during pregnancy or breastfeeding?

Pregnancy: VOLTAPRAZ 20MG TAB (Vonoprazan) is generally not recommended during pregnancy due to limited information on its use in pregnant women and animal studies showing embryo-fetal toxicity at high doses. Your doctor will weigh the potential benefits against the risks if considering this medication during pregnancy.

Breastfeeding: The manufacturer advises against breastfeeding while taking Vonoprazan due to potential risks, specifically liver damage observed in nursing rodents. If treatment is necessary for the mother, pumping and discarding breast milk is recommended during treatment and for two days after the last dose.

Can VOLTAPRAZ 20MG TAB be taken with other medications?

Vonoprazan can interact with several medications. It may significantly decrease the effectiveness of certain HIV drugs (such as rilpivirine, atazanavir, and nelfinavir) and is contraindicated with rilpivirine-containing products. It can also interact with:

• Anticoagulants like warfarin (may increase bleeding risk).
• Certain antifungals (e.g., ketoconazole, itraconazole) by altering their absorption.
• Digoxin (may enhance its effects).
• Methotrexate (may increase its blood levels).
• Iron salts and other drugs that require stomach acid for proper absorption.
• It may also inhibit certain liver enzymes (CYP3A4, CYP2C9, CYP2D6, CYP2B6), which can affect how other medications are metabolized.

Always inform your doctor and pharmacist about all prescription, over-the-counter medications, vitamins, herbs, and supplements you are taking to avoid potential interactions.

What precautions should be taken while using VOLTAPRAZ 20MG TAB?

Inform your doctor if you have kidney or liver disease, a history of low magnesium levels (hypomagnesemia), osteoporosis, or other bone problems. Long-term use of Vonoprazan may lead to vitamin B12 deficiency and low magnesium levels, so your doctor may monitor these periodically. Additionally, there is a risk of developing benign stomach polyps with prolonged use.

What happens if a dose of VOLTAPRAZ 20MG TAB is missed?

• For once-daily dosing (e.g., for erosive esophagitis or non-erosive GERD): Take the missed dose as soon as you remember, unless it has been more than 12 hours since your usual dose time. In that case, skip the missed dose and take your next dose at the regular scheduled time. Do not double the dose.
• For twice-daily dosing (e.g., for H. pylori infection): Take the missed dose as soon as you remember, unless it has been more than 4 hours since the missed dose. If more than 4 hours have passed, skip the missed dose and continue with your regular dosing schedule. Do not double the dose.

How should VOLTAPRAZ 20MG TAB be stored?

Store VOLTAPRAZ 20MG TAB in a closed container at room temperature, typically between 20°C to 25°C (68°F to 77°F). Keep it away from excessive heat, moisture, and direct light. It's crucial to keep all medicines out of the reach of children.
