Metrolyl suppositories

Health and Nutrition > Medicines > M



How does it work?

Metrolyl suppositories contain the active ingredient metronidazole, which is a type of medicine called an antibiotic. (NB. Metronidazole is also available without a brand name, ie as the generic medicine.) Metronidazole is used to treat infections caused by bacteria and other micro-organisms called protozoa.

Metronidazole works by entering bacterial and protozoal cells and interfering with their genetic material (DNA). It damages the DNA and also prevents the bacteria and protozoa from forming new DNA. This ultimately results in metronidazole killing the micro-organisms, which clears up the infection.

Metronidazole kills a wide variety of bacteria that are known collectively as anaerobic bacteria. This means that they do not need oxygen to grow and multiply. Anaerobic bacteria can cause infections in areas of the body such as the bones, gut, pelvic cavity and gums. Metronidazole is used to treat these types of infections.

Metronidazole is also used to prevent infection following surgery, particularly gynaecological surgery and surgery on the gut, where many anaerobic bacteria may be found. In high doses, metronidazole penetrates the brain and can be used to treat abscesses in the brain.

To make sure the micro-organisms causing an infection are susceptible to metronidazole your doctor may take a tissue sample, for example a swab from the infected area.

Metrolyl suppositories are used when administration of metronidazole by mouth is not possible. The metronidazole is absorbed into the bloodstream from the rectum.
