Abstract
For more than 50 years, 5-nitroimidazole (5-NI) drugs, especially metronidazole, have been in use in the treatment of children and adults with giardiasis. This disease, caused by the flagellated protozoan Giardia lamblia , is recognised as a major cause of parasite-induced diarrhoea, and is currently an important public health problem, placing a heavy burden on both diagnostic and treatment services at health care institutions, mostly in developing countries, but also in highly industrialized countries. Although giardiasis has been a threat to mankind for thousands of years, until recently, it was relatively neglected. As a consequence, the pharmaceutical industry has had few incentives to engage in the development of new drugs and, at present, nitazoxanide is the first new drug developed for treating giardiasis in more than 20 years. Currently, the increasing number of reports of refractory cases with 5-NI drugs and other antigiardial agents has raised concern and led to a search for other compounds, some of which have arisen due to the introduction of drugs initially addressed to other diseases. Information is required to know if 5-NI are still efficacious in the present context, in which resistance to common antimicrobials is a threat. Additionally, it is discussed some of the most important points of antigiardial pharmacotherapy available at present and the future prospects of development of new agents.
