VONOMAC 20MG TAB

Name

• Brand Name: VONOMAC 20MG TAB
• Manufacturer: Macleods Pharmaceuticals Ltd

Composition VONOMAC 20MG TAB contains Vonoprazan 20 mg as its active ingredient. Vonoprazan is classified as a potassium-competitive acid blocker (PCAB). It works by inhibiting the H+, K+-ATPase enzyme in the stomach's parietal cells, thereby reducing the amount of acid produced in the stomach. Unlike some other acid-reducing medications, it does not require acid activation and can bind to the active pumps reversibly, providing effective and consistent gastric pH control.

Uses VONOMAC 20MG TAB is prescribed for the treatment and prevention of various gastrointestinal conditions related to excessive stomach acid. These include:

• Reflux Esophagitis: Healing damage to the esophagus caused by stomach acid and alleviating associated symptoms like heartburn and acid reflux.
• Gastric and Duodenal Ulcers: Treatment of existing ulcers and prevention of their recurrence.
• Helicobacter pylori (H. pylori) Infection: Used in combination with antibiotics (such as clarithromycin and/or amoxicillin) to eliminate H. pylori bacteria, which can cause stomach ulcers.
• Gastroesophageal Reflux Disease (GERD): Decreases stomach acid to alleviate symptoms like heartburn and acid regurgitation.
• Prevention of Ulcer Recurrence: Prevents the recurrence of gastric or duodenal ulcers during the use of low-dose aspirin or NSAIDs (non-steroidal anti-inflammatory drugs).

Dosage and Administration

• VONOMAC 20MG TAB should be taken orally as advised by a healthcare professional.
• It is typically taken once daily, but for H. pylori eradication, a twice-daily regimen in combination with other medications is common.
• The tablet should be swallowed whole with a glass of water; it should not be broken, crushed, or chewed.
• It can be taken with or without food.
• The duration of treatment varies based on the medical condition, for example, 4-8 weeks for reflux esophagitis, 6 weeks for duodenal ulcers, and 8 weeks for gastric ulcers.

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

What is VONOMAC 20MG TAB used for?

VONOMAC 20MG TAB is used to treat conditions associated with excessive stomach acid. These include healing and maintaining the healing of erosive esophagitis (inflammation and damage to the esophagus) and relieving associated heartburn. It is also prescribed for the treatment of gastric and duodenal ulcers and to prevent their recurrence, especially when caused by NSAID or low-dose aspirin use. Additionally, it is used in combination with antibiotics to eradicate Helicobacter pylori (H. pylori) infection, which can cause stomach ulcers.

How does VONOMAC 20MG TAB work?

VONOMAC 20MG TAB works by reducing the amount of acid produced in the stomach. Its active ingredient, Vonoprazan, is a potassium-competitive acid blocker (PCAB) that inhibits the H+, K+-ATPase enzyme system in the stomach's parietal cells. Unlike some other acid reducers, it does not require acid activation and can selectively target parietal cells, binding reversibly to the active pumps to block gastric acid secretion. This mechanism provides effective and consistent control of gastric pH.

What is the usual dosage for VONOMAC 20MG TAB?

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

• For healing erosive esophagitis and associated heartburn: Typically, 20 mg once daily for 8 weeks.
• For maintenance of healed erosive esophagitis and associated heartburn: Usually, 10 mg once daily for up to 6 months.
• For H. pylori infection: 20 mg twice daily, often in combination with amoxicillin and/or clarithromycin, for 14 days. VONOMAC 20MG TAB should be swallowed whole with water and not chewed or crushed. It can generally be taken with or without food, as advised by your doctor.

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

Common side effects may include diarrhea, stomach pain, nausea, indigestion, abdominal bloating, and high blood pressure. More serious, though less common, side effects can include kidney problems (like acute tubulointerstitial nephritis), Clostridioides difficile-associated diarrhea, bone fractures (especially with long-term or high-dose use), and low levels of vitamin B12 or magnesium (hypomagnesemia). If you experience severe or persistent side effects, contact your healthcare provider.

Is VONOMAC 20MG TAB safe during pregnancy or breastfeeding?

Pregnancy: Limited safety information is available for VONOMAC 20MG TAB in pregnant women. It is advised to consult your doctor if you are pregnant or planning to become pregnant, to discuss the potential risks and benefits. Breastfeeding: It is generally not recommended to breastfeed while taking VONOMAC 20MG TAB, as the active ingredient, Vonoprazan, may pass into breast milk. Your doctor can provide guidance on whether to discontinue breastfeeding or use an alternative medication.

Can VONOMAC 20MG TAB be taken with other medications?

VONOMAC 20MG TAB can interact with certain medications. It is crucial to inform your doctor about all prescription, over-the-counter medications, and herbal supplements you are currently taking to avoid potential interactions. For instance, it may interact with antiretrovirals like rilpivirine, atazanavir, and nelfinavir, potentially reducing their effectiveness. It may also alter the absorption of some antifungals (e.g., ketoconazole) and can increase the concentration of certain drugs metabolized by CYP3A enzymes.

What precautions should be taken when using VONOMAC 20MG TAB?

Before taking VONOMAC 20MG TAB, inform your doctor if you have any allergies to its ingredients or any other medications. Discuss any pre-existing medical conditions, especially kidney or liver disorders, osteopenia, osteoporosis, or low levels of calcium, magnesium, or potassium in your blood. Long-term use of acid-reducing medications may increase the risk of certain infections, bone fractures, vitamin B12 deficiency, hypomagnesemia, and fundic gland polyps. Avoid alcohol and smoking, as they can exacerbate stomach issues and affect treatment effectiveness.

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

If you miss a dose of VONOMAC 20MG TAB:

• For once-daily dosing (e.g., for erosive esophagitis): Take the missed dose as soon as you remember, provided it is within 12 hours of your usual time. If more than 12 hours have passed, skip the missed dose and continue with your regular schedule. Do not take a double dose.
• For twice-daily dosing (e.g., for H. pylori infection): Take the missed dose as soon as you remember, provided it is within 4 hours of your usual time. If more than 4 hours have passed, skip the missed dose and continue with your regular schedule. Do not take a double dose to make up for a missed one.

How should VONOMAC 20MG TAB be stored?

VONOMAC 20MG TAB should be stored in a cool and dry place, away from direct sunlight, heat, and moisture. The temperature should generally be below 30°C. Keep all medicines out of the sight and reach of children.
