How Caviter FD Products work

Rifampicin + Isoniazid is a combination of two antibiotics: Rifampicin + Isoniazid1 and Rifampicin + Isoniazid2, which treats tuberculosis (TB). Rifampicin + Isoniazid1 works by inactivating a bacterial enzyme (RNA-polymerase) which is required by TB bacteria to make essential proteins and to reproduce. Rifampicin + Isoniazid2 prevents these bacteria from forming their own protective covering. Together, they kill the bacteria and eradicate the infection.
