Mechanism of Action

Metronidazole works on acne by reducing inflammation, killing bacteria, and reducing the production of excess oil in the skin. It is a type of antibiotic that targets specific bacteria associated with acne, such as Propionibacterium acnes. By targeting these bacteria, metronidazole helps to clear up existing acne lesions and prevent new ones from forming.

Furthermore, metronidazole has anti-inflammatory properties that help to decrease redness and swelling associated with acne. It also helps to regulate the production of sebum, the oily substance that can clog pores and contribute to the development of acne.

Overall, metronidazole’s mechanism of action makes it an effective treatment for acne, particularly for those with inflammatory acne lesions and red, swollen pimples.

Mechanism of Action

Metronidazole works on acne by inhibiting the growth of bacteria that contribute to acne formation. It has both antibacterial and anti-inflammatory properties, making it effective in treating inflammatory acne.

Metronidazole works by entering the bacterial cell and interfering with its DNA synthesis, disrupting the replication process and ultimately leading to bacterial cell death. This action helps to reduce the number of acne-causing bacteria on the skin, leading to a decrease in inflammation and improvement in acne symptoms.
