Tb Razine Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Tb Razine is a brand name. Its generic name is Pyrazinamide.
Introduction
Tb Razine (PZA) is a drug used for the treatment of tuberculosis (TB). It is a bacteriocidal drug, which works by inhibiting the growth of mycobacteria responsible for TB. Tb Razine is an alternative to other agents such as isoniazid, rifampin, ethambutol, and streptomycin.
Uses
Tb Razine is typically used as part of a combination anti-tuberculosis therapy. It is commonly used for the treatment of active tuberculosis caused by susceptible strains of mycobacteria.
Mechanism of Action
Tb Razine works by inhibiting the enzymes necessary for the production of mycolic acid, which is an essential component of mycobacterium's cell wall. Without these enzymes, the cell wall of the mycobacteria is disrupted and their replication is prevented, leading to their death.

The exact time it takes to see improvement varies among individuals. Generally, patients should start to see an improvement in their symptoms within the first week. It usually takes about two months for the infection to completely resolve.
