The causative agents of the disease are unicellular intestinal flagellates Giardia intestinalis, which arise in a vegetative (trophozoite) and cystous (cyst) form.
The treatment of giardiasis today is not as complicated as it used to be, and there are various drugs and tablets for lamblia in adults on the market. Consider what to guide you when choosing a treatment.
G. intestinalis is the originator of an alimentary diarrheal disease known as giardiasis. Despite the massive conclusions of the analyzes, it does not necessarily come to pathological changes. Most infections are either asymptomatic or subclinical. Only 10% of those infected have clinical manifestations
The acute stage of giardiasis has a short course (3-4 days) and often mimics acute viral enteritis, bacterial dysentery or other bacterial food poisoning, acute intestinal amebiasis or diarrhea caused by toxigenic strains of E. coli.
The incubation period for the acute phase is 12-20 days. Manifested by sudden diarrhea, loss of appetite, nausea, vomiting, and increased flatulence. The stool is light, watery, with a strong odor, containing a large amount of fat (greasy appearance) and mucus, without blood, cellular elements and remnants of worms.
The subacute and chronic phase is manifested by pressing pain in the epigastrium and hypochondria, especially after eating. Diarrhea alternates with constipation, and children have secondary anemia and slow weight gain.
After a few weeks, spontaneous healing can be achieved. Sometimes the disease persists for several months or even years, turning into an asymptomatic form associated with the carriage of cysts.
In addition to the intestinal form of giardiasis, a hepatobiliary form can be demonstrated (in 50% of cases). It manifests itself in the form of acute or chronic cholecystitis. With severe damage to the intrahepatic bile ducts and liver parenchyma, jaundice and hepatomegaly may develop.
In the treatment of lamblia tablets, a popular medicine is Metronidazole (Flagil), which is taken in adults in a dose of one tablet (250 mg) 3 times a day. The therapeutic course is 10 days. The recommended dosage for children is 5 mg / kg three times a day. Duration - 5-10 days.
An alternative treatment is Ornidazole (Avrazor), which is taken twice a day, 500 mg. The therapeutic course is 5-10 days.
If the treatment with the above drugs does not show efficacy, Tinidazole (Fazizin) 2 g can be used once (children - 50-75 mg / kg once).
The mechanism of action of these drugs for giardiasis is the effect on the enzyme process of the parasite, which causes its destruction. The effectiveness of therapy is monitored by microscopic examination 2 weeks after its completion.
Entisol is a medicine that belongs to the antibiotics of the nitroimidazole group. The active substance of the drug is a compound metronidazole.
- Principle. Metronidazole penetrates bacterial cells, attacks their cellular enzymes and damages the addition of bacterial DNA. A good effect is achieved with anaerobic bacteria that do not need oxygen for life.
- Application. Entisol kills various anaerobic bacteria and is effective against some protozoa, in particular G. intestinalis. Women can use the drug to treat deep pelvic inflammation and gynecological infections (both bacterial in nature and those caused by protozoa). It is effective in the treatment of diverticulitis and pseudomembranous colitis, it is suitable for intestinal diseases of an inflammatory nature. In combination with other antibiotics, it is suitable for re-treatment of infectious inflammation of the stomach caused by Helicobacter Pylori.
