Final answer:
The prefix RIFA- refers to antibacterial drugs, such as Rifampin, used primarily in the treatment of tuberculosis.
Step-by-step explanation:
The prefix RIFA- is commonly associated with antibacterial drugs, specifically those used in the treatment of tuberculosis (TB). One of the most well-known drugs with this prefix is Rifampin (also known as Rifampicin), which is an antibiotic that belongs to the class of medications called rifamycins.
Rifampin works by inhibiting the RNA polymerase in bacteria, thereby disrupting their ability to make proteins and multiply. It is often part of a combination therapy to effectively treat TB and to prevent the development of antibiotic resistance.
