Table of contents:

Pyrazinamide is an antibiotic medication that is used to treat tuberculosis. Its mechanism of action is not well understood and is still the subject of research, but it is believed to work by inhibiting the growth of the bacteria responsible for causing tuberculosis.

Pyrazinamide is converted to an active form called pyrazinoic acid by a specific enzyme called pyrazinamidase, which is produced by the bacterium responsible for causing tuberculosis. Under acidic conditions, such as those that occur inside the infected cells, pyrazinoic acid is believed to inhibit the synthesis of fatty acids that are vital for the survival and growth of the bacterium, leading to its death.

Uses and Dosage

Pyrazinamide is typically administered as an oral tablet, taken once daily at a consistent time each day or in larger doses twice per week, with or without food. To ensure appropriate usage of this medication, follow the dosage instructions on your prescription label and clarify any lingering confusion with your doctor or pharmacist.

Avoid making any changes to your pyrazinamide intake, such as taking more, taking less frequently, or in smaller or larger amounts, without consulting your healthcare provider to avoid potential harmful medical effects.

The recommended dosage of Pyrazinamide may vary depending on the patient's weight and the type of tuberculosis being treated. The usual adult dose for active TB for patients weighing 40 to 75 kg is typically 1000 to 1500 mg orally once a day.
