Macrobac 500mg Tablet

Macrobac 500mg Tablet contains Azithromycin, which belongs to the class of antibiotics known as macrolides. It is primarily used for the treatment of various bacterial infections caused by susceptible organisms.

Uses:

• Macrobac 500mg Tablet is prescribed for the treatment of respiratory tract infections such as pneumonia, bronchitis, and sinusitis.
• It is also indicated for the management of skin and soft tissue infections, including cellulitis and impetigo.
• Additionally, Azithromycin may be used to treat sexually transmitted infections (STIs) such as chlamydia and gonorrhea.

How It Works:

• Azithromycin, the active ingredient in Macrobac 500mg Tablet, works by inhibiting bacterial protein synthesis, thereby preventing the growth and multiplication of susceptible bacteria.
• It binds to the 50S ribosomal subunit of the bacterial ribosome, interfering with RNA-dependent protein synthesis and ultimately leading to bacterial cell death.

Dosage:

• The dosage of Macrobac 500mg Tablet should be determined by the prescribing physician based on the severity of the infection, the patient’s age, weight, and renal function.
• It is typically taken orally once daily, with or without food, for a specified duration as directed by the healthcare provider.
• The duration of treatment may vary depending on the type and location of the infection being treated.

Precautions:

• Macrobac 500mg Tablet should be used with caution in patients with hepatic impairment, as Azithromycin is primarily metabolized by the liver.
• It is contraindicated in individuals with a known hypersensitivity or allergic reaction to Azithromycin or any other macrolide antibiotics.
• Caution should be exercised when administering Azithromycin to patients with a history of prolonged QT interval or those taking medications that prolong the QT interval, as this may increase the risk of cardiac arrhythmias.

Side Effects:

When Not to Use:

• Macrobac 500mg Tablet is contraindicated in patients with a history of hypersensitivity or allergic reactions to Azithromycin or any macrolide antibiotics.
• It should not be used concomitantly with ergot derivatives due to the potential for ergotism (vasoconstriction and ischemia) or with medications known to prolong the QT interval, as this may increase the risk of cardiac arrhythmias.
