Vonzai 10mg Tab

VONZAI 10MG Tablet

VONZAI 10MG Tablet is a medication developed by ALKEM LABORATORIES LIMITED, primarily used to manage conditions associated with excessive stomach acid.

Composition

VONZAI 10MG Tablet contains Vonoprazan 10mg as its active ingredient. Vonoprazan is classified as a potassium-competitive acid blocker (P-CAB), which functions by reversibly inhibiting the H+, K+-ATPase (proton pump) enzyme in the stomach's parietal cells. This mechanism effectively reduces the production of gastric acid.

Uses

VONZAI 10MG is prescribed for a range of gastrointestinal disorders, including:

• Treatment of gastric ulcers.
• Treatment of duodenal ulcers.
• Treatment of reflux esophagitis (also known as erosive esophagitis).
• Prevention of recurrence of gastric or duodenal ulcers during the administration of low-dose aspirin.
• Prevention of recurrence of gastric or duodenal ulcers during the administration of non-steroidal anti-inflammatory drugs (NSAIDs).
• As an adjunct to Helicobacter pylori eradication therapy, typically in combination with antibiotics such as amoxicillin and clarithromycin or metronidazole.
• Management of Gastroesophageal Reflux Disease (GERD).

Dosage and Administration

VONZAI 10MG Tablets can be taken with or without food, as directed by a healthcare professional. For optimal benefits, it should be taken at the same time each day.

• Gastric Ulcer: The usual adult dose is 20 mg once daily for 8 weeks.
• Duodenal Ulcer: The usual adult dose is 20 mg once daily for 6 weeks.
• Reflux Esophagitis: The usual adult dose is 20 mg once daily for 4 weeks, extendable up to 8 weeks if necessary. For maintenance therapy, 10 mg once daily, which may be increased to 20 mg if efficacy is insufficient.
• Prevention of Recurrence of Gastric/Duodenal Ulcer (during low-dose aspirin/NSAID use): The usual adult dose is 10 mg once daily.
• Helicobacter pylori Eradication: Typically involves a three-drug regimen where 20 mg of Vonoprazan is administered twice daily for seven days, alongside specific antibiotics (e.g., 750 mg amoxicillin and 200 mg clarithromycin, or 750 mg amoxicillin and 250 mg metronidazole if initial treatment fails).

Side Effects

Common side effects may include:

• Diarrhea, constipation
• Nausea, abdominal distension, indigestion, bloating, stomach pain
• Rash, drug eruption, urticaria (hives)
• Increased liver enzymes (AST, ALT, ALP, LDH, gamma-glutamyl transferase)
• Headache, dizziness, sleepiness, increased appetite, weight gain

Serious but less common side effects reported include drug hypersensitivity (including anaphylactic shock), hepatotoxicity, jaundice, edema, and eosinophilia.

Precautions

• Hypersensitivity: VONZAI 10MG is contraindicated in patients with known hypersensitivity to Vonoprazan or any of its excipients.
• Drug Interactions: It is contraindicated in patients receiving atazanavir sulfate, nelfinavir, or rilpivirine hydrochloride. Caution is advised when used concurrently with other medications, particularly CYP3A4 inhibitors.
• Liver and Kidney Impairment: Patients with mild hepatic impairment (Child-Pugh A) generally do not require dose adjustment. However, avoid use in patients with moderate to severe hepatic impairment (Child-Pugh B or C). Use with caution and potential dose adjustment in patients with kidney disease.
• Elderly and Pediatric Use: Administer with care in elderly patients due to potentially decreased physiological functions. The safety and efficacy in children under 18 years of age have not been established.
• Pregnancy and Lactation: Should be used in pregnant women only if the expected therapeutic benefit outweighs any possible risk. It is advisable to avoid use in nursing mothers; if administration is indispensable, breastfeeding should be discontinued.
• Long-term Treatment: Close observation, including endoscopy, is recommended during long-term treatment.
• Gastric Malignancy: A symptomatic response to Vonoprazan does not rule out the presence of gastric malignancy.
• Risk of Infection: There is an increased risk of Clostridium difficile-associated diarrhea, a caution also observed with proton pump inhibitors (PPIs).
• Bone Health/Magnesium Levels: An increased risk for osteoporosis-related fractures and severe hypomagnesaemia has been reported with prolonged PPI treatment, and similar considerations may apply to P-CABs.
• Driving and Operating Machinery: As Vonoprazan may cause dizziness and sleepiness, caution is advised when performing tasks requiring mental alertness.

Storage

Store VONZAI 10MG Tablets below 30°C in a cool and dry place. Protect the medicine from direct sunlight and moisture. Keep all medicines out of the reach of children. Do not use the medication past its expiration date.

Here are some frequently asked questions about VONZAI 10MG TAB (Vonoprazan) by ALKEM LABORATORIES LIMITED, along with concise answers:

What is VONZAI 10MG TAB used for?

VONZAI 10MG TAB, containing Vonoprazan, is primarily used to treat conditions caused by excessive stomach acid. These include gastric ulcers, duodenal ulcers, and reflux esophagitis. It is also used to prevent the recurrence of gastric or duodenal ulcers during the administration of low-dose aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) and as an adjunct to Helicobacter pylori (H. pylori) eradication therapy.

How does VONZAI 10MG TAB work?

VONZAI 10MG TAB works as a potassium-competitive acid blocker (P-CAB). Its active ingredient, Vonoprazan, inhibits the H+, K+-ATPase enzyme, also known as the proton pump, in the parietal cells of the stomach lining. By blocking this enzyme, it effectively reduces the production of gastric acid, thereby helping to heal ulcers and alleviate symptoms associated with acid-related disorders.

What is the usual dosage for VONZAI 10MG TAB?

The dosage of VONZAI 10MG TAB can vary depending on the condition being treated. For gastric ulcers, the usual adult dose is 20 mg once daily for 8 weeks. For duodenal ulcers, it's typically 20 mg once daily for 6 weeks. For reflux esophagitis, it's often 20 mg once daily for 4 weeks, which may be extended up to 8 weeks if needed, with a maintenance dose of 10 mg once daily for recurrent cases. For preventing ulcer recurrence during low-dose aspirin or NSAID administration, the usual dose is 10 mg once daily. When used for H. pylori eradication, it's typically 20 mg twice daily for seven days, in combination with specific antibiotics. It can be taken with or without food.

What are the possible side effects of VONZAI 10MG TAB?

Common side effects of VONZAI 10MG TAB may include diarrhea, constipation, nausea, abdominal distension, and abnormal liver function tests. Less common but serious side effects can include drug hypersensitivity reactions (including anaphylactic shock), drug eruption, urticaria, hepatotoxicity, jaundice, and skin rash.

Is VONZAI 10MG TAB safe during pregnancy or breastfeeding?

VONZAI 10MG TAB should generally be used during pregnancy only if the potential therapeutic benefit is considered to outweigh any possible risks to the fetus, as clinical studies in pregnant women are limited. It is advisable to avoid VONZAI 10MG TAB during breastfeeding. If the medication is essential for the mother, breastfeeding should be discontinued.

Can VONZAI 10MG TAB be taken with other medications?

VONZAI 10MG TAB is contraindicated in patients taking atazanavir sulfate, nelfinavir, or rilpivirine hydrochloride. Caution is advised when taking it with strong CYP3A4 inhibitors, such as clarithromycin, as this may increase Vonoprazan concentrations. It may also affect the absorption of other medicines whose effectiveness depends on acidic stomach pH, including certain antifungal agents and iron salts. Always inform your doctor about all other medications, supplements, and herbal products you are taking.

What precautions should be taken while taking VONZAI 10MG TAB?

You should inform your doctor if you have any known allergies to Vonoprazan or its components. Use VONZAI 10MG TAB with caution if you have severe liver or kidney impairment, or if you are elderly, as physiological functions may be decreased in these populations. Long-term use of acid-suppressing medications like Vonoprazan may increase the risk of Clostridium difficile gastrointestinal infection and potentially lead to low levels of magnesium, calcium, or potassium in the blood.

What happens if a dose of VONZAI 10MG TAB is missed?

If you miss a dose of VONZAI 10MG TAB, take it as soon as you remember on the same day. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one. If you miss multiple doses, consult your doctor for guidance on adjusting your dosing. For erosive esophagitis or GERD, take a missed dose if it's within 12 hours of the usual time. For H. pylori treatment, take it if it's within four hours.

How should VONZAI 10MG TAB be stored?

VONZAI 10MG TAB should be stored at room temperature, ideally below 30°C (86°F). Keep it in a cool, dry place, protected from direct sunlight, excessive heat, and moisture. Always ensure the medicine is kept out of the reach of children and pets.
