Candidiasis is an opportunistic mycoses caused by the . The genus comprises of many species of which Candidaalbicansis the most common.

Candidiasis can cause a wide spectrum of clinical syndromes which include cutaneous candidiasis, , respiratory tract candidiasis, genitourinary tract candidiasis, hepatosplenic candidiasis and systemic candidiasis. are drugs widely accepted for the treatment of fungal infections.

Conventional antifungal drugs used in the treatment of candidiasis belong to three (3) principal classes: the Echinocandins (caspofungin, anidulafungin and micafungin) used for the treatment of systemic candidiasis, the Azoles (fluconazole, voriconazole, posaconazole) and the Polyenes (amphotericin B) for the treatment of cutaneous and chronic mucocutaneous candidiasis.

The treatments of these with the conventional antifungal drugs vary substantially and are based on the anatomic location of the infection.

The patients’ underlying disease and immune status, the patients’ risk factors for infection, and the specific species of Candida responsible for infection, though these species are either susceptible or resistant to the drugs, for instance, Candida krusei is susceptible to voriconazole but resistant to fluconazole.

Conventional antifungal drugs are an essential key towards the , but require monitoring and modification to ensure adequate treatment of the disease.


Candidiasis is an opportunistic mycoses. It is a fungal infection caused by the yeast genus Candida.Several species of the yeast Candida are capable of causing candidiasis (Brookset al., 2013).

Thegenusis composedof organisms such as Candidaalbicans(common cause of candidiasis), Candidaglabrata, Candidaparapsilosis,Candida balanitis, Candida guilliermondii,andCandidakrusei (Pfalleretal.,2007).

Candidaspecies belong to the normalmicrobiotaofanindividual’s mucosal oralcavity, gastrointestinal tract andvagina (Shaoetal.,2007),andare manifested by mucocutaneous lesions, fungemia, and sometimes focal infection of multiple sites.

Symptoms depend on the site of infection and include dysphagia, skin and mucosal lesions, blindness, vaginal symptoms (itching, burning, discharge), fever, shock, oliguria, renal shutdown, and disseminated intravascular coagulation.

Diagnosis is done by histopathology and cultures from normally sterile sites. Conventional antifungal drugs are drugs widely accepted to fight fungal organisms causing infection and diseases in humans.

In the United States, only ten (10) antifungal drugs are currently approved by the Food and Drug Administration (FDA) for the therapy of systemic fungal infections (William, 2000).
