Posacad GR Tablet

1. Product Introduction

Posacad GR Tablet is an advanced antifungal medicine that contains Posaconazole, a second-generation triazole antifungal agent. It is specially formulated as a gastro-resistant (GR) tablet to ensure maximum absorption in the intestine while being protected from stomach acid. This form of the medicine is widely used to treat serious fungal infections, especially in patients who have weak immune systems, such as those undergoing chemotherapy or stem cell transplants.

Posaconazole works by inhibiting an enzyme that fungi need to produce their cell membranes. This action stops the growth and multiplication of fungi, effectively treating infections caused by Candida, Aspergillus, and other rare fungal species.

2. Uses of This Medicine

Posacad GR Tablet is primarily used to treat and prevent severe fungal infections in high-risk patients. Common medical conditions for which this medicine is prescribed include:

• Invasive Aspergillosis: A life-threatening fungal infection affecting the lungs and other organs, especially in immunocompromised patients.

• Oropharyngeal Candidiasis: Fungal infection in the mouth and throat, often in patients with weakened immunity or those undergoing chemotherapy.

• Prophylaxis of Fungal Infections: Especially in patients with hematologic malignancies (like leukemia) or post bone marrow transplantation, who are highly vulnerable to infections.

• Treatment of Resistant Fungal Infections: Where other antifungal agents such as fluconazole or itraconazole fail or are not tolerated.

• Mucormycosis (in select cases): An aggressive and rare fungal infection, especially during or after COVID-19 in diabetic or immunosuppressed patients.

3. Benefits of This Medicine

• Broad-Spectrum Antifungal Protection: Posaconazole is effective against a wide range of fungi, including those resistant to older antifungals.

• Life-Saving Prophylaxis: In patients undergoing chemotherapy or organ transplant, Posacad GR helps prevent deadly fungal infections before they occur.

• Convenient Once-Daily Dosing: The GR tablet offers sustained drug levels in the body, often allowing for once-daily dosing after the initial loading dose.

• Gastro-Resistant Formulation: Ensures better absorption in the intestine and fewer gastrointestinal side effects compared to oral suspensions.

• Effective Against Drug-Resistant Strains: Useful in treating infections that no longer respond to common antifungal agents.
