How Forecox Kit works
Forecox Kit is a combination of four medicines: Isoniazid, rifampicin, ethambutol and pyrazinamide which treat tuberculosis. Isoniazid works by preventing the TB bacteria from forming their own protective covering, while rifampicin inactivates a bacterial enzyme (RNA-polymerase) which is required by TB bacteria to make essential proteins and to reproduce. Together, they kill the bacteria and eradicate the infection. Ethambutol and pyrazinamide, on the other hand work by slowing the growth of these bacteria.
