Fungi is the most wide spread species of plantae kingdom on earth. It habitats ranger from hundreds of degrees of temperature to the most dehydrated conditions. Due to its versatility and successful survival, the fungi also infect and damage human bodies. Diseases of various organs are invaded by a variety of fungi. Consequently, research has lead to the development of anti-fungi drugs and Diflucan is one of them.
Infections of both, superficial and deep nature are treated by Diflucan effectively. The drug chiefly is a fungi-static i.e. it halts the growth of fungi. The drug acts to inhibit the activity of demethylase enzyme significantly. Fungal demethylase enzyme is responsible for the accommodation of lanosterol and ergosterol in their cellular membranes to complete its structure. When inhibit, the membrane formed is defected and the fungus is prevented from thriving in the human body.
Diflucan is an important treatment-resistant drug that is to be given when all the fungicides have failed to cut fungal growth at the infection site. Candida albicans is a special kind of yeast that infects human organs like skin armpits, mouth, groin, folds of buttocks and also the genital organs in both the sexes. Candidasis can be superficial or of systemic form in more severe cases. Diflucan provides an effective treatment for candidasis and reduced the infection significantly.
Vaginal yeast infection is most susceptible when taking oral pills, irritation by vaginal douches, pregnancy tensions and vaginal sex immediately after anal sex. 75% of the women suffer from yeast infection at some stage of their life.
Patients with chronic fungal or yeast infection are readily curable by the drug. Diflucan is toxic if taken for too long but is counted among its family with less toxicity. Another positive aspect of diflucan over other anti-fungi drug is that it is absorbed systemically in an effective way.
The natural acidity of stomach does not interfere with the absorption of the drug and its subsequent appearance in urine, tears and skin. This is on of the characters that make the drug perfect for the treatment of vaginal infections and skin infections. Orally taken, Diflucan is prescribed with a dosage of 150mg tablets daily for genital infections, 500-600 mg daily for systemic infections and 150-300 mg weekly for skin infections. For immediate treatment of adverse meningitis 800mg potency is advised to be taken daily.
The side effects of the drug include cardiac arrhythmias and toxicity of liver. It appears in the breast milk readily thus unadvisable for lactating women. People showing allergic responses to other azole drugs should also not resort to such drug. Liability to anaphylaxis may also be increased. Adverse drug reactions may include anorexia, fatigue, headache, nausea, diarrhea, constipation, and hepatic failure and torsades de pointes in the rarest conditions.
