How Metronidazole Works

Metronidazole is an antibiotic that works by stopping the growth of bacteria and parasites. It achieves this by interfering with their DNA, which leads to the inhibition of their protein synthesis and ultimately causes their death. This antibiotic is effective against a wide range of anaerobic bacteria, protozoa, and helminths.

Mechanism of Action Metronidazole enters bacterial and parasite cells and is then converted to an active form. This active form damages bacterial and parasite DNA, preventing them from replicating and surviving.
Targeted Organisms Metronidazole is particularly effective against anaerobic bacteria, such as Clostridium, Bacteroides, and Fusobacterium species. It is also used to treat infections caused by protozoa, including Giardia and Trichomonas, as well as certain parasitic worms.
Resistance Although resistance to metronidazole is rare, it can occur. Resistance mechanisms may involve changes in the bacterial target enzyme or reduced drug penetration into the bacterial cell.

How Metronidazole Works

Metronidazole works by entering bacterial and protozoan cells and damaging their genetic material. It interferes with the DNA synthesis of these microorganisms, leading to their death. This antibiotic is particularly effective against anaerobic bacteria and certain parasites like Giardia and Trichomonas.

Metronidazole is a prodrug, which means it needs to be activated by specific enzymes inside the target cells to become effective. Once inside the cells, the active form of Metronidazole disrupts the DNA structure, leading to cell death and stopping the growth and replication of the microorganisms.
