Case Study Of Ketoconazole

Antifungal creams are used to treat things like athlete’s foot, ringworm of the groin and body, skin infection because of Candida yeast. A serious systemic infections like crypotococcal meningitis. Antifungal injections are used to treat infections like Candidiasis, Coccidiomycosis, and Crypotococcal Meningitis. Antifungals work by exploiting differences in mammalian and fungal cells to kill the fungal organisms with no dangerous effects on the host. Fungal and human cells are alike at the molecular level. Antifungal drugs can cause side effects; some could be fatal if the drug is not used properly (Antifungal medication, n.d.).

Topical medications come in the form of creams and gels and are applied directly to the skin surface usually to treat skin conditions.

Topical drugs such as patches, ointment, and cream are applied directly on the skin and can be absorbed fast or with a delayed action. The term pharmacokinetics is the study of the movement of the drug in the human’s body. This includes the site of absorption (movement of drug from entry to tissue), how it is distributed (movement in the circulatory system to intended destination), how it is metabolized (break down in the liver), and excretion (elimination from the body). This unit also described the term half-life, which is how long the human body takes to break down a drug, absorb and excrete it and short half-life, which are medications excreted by the body quicker than long half-life drugs. The term pharmacodynamics is any of the changes in the patient’s body resulting from the medicine taken. It is highly important for the patient to know of the used drug’s side effects (unintended effects), adverse effects (unintended effects that can be harmful), and any possibilities of allergic reactions (most severe adverse response of a

If these medications are unsuccessful, you can then go to a doctor and get a prescribed medication that are usually also antifungals which can be put directly on the skin. Some of these include Mentax, clotrimazole, and naftifine. Prescription antifungals can also be taken as a pill, which are called oral antifungals. Examples of oral antifungals include fluconazole and itraconazole. Antifungals work by targeting a substance in the cell walls, making the contents inside to leak out and the cells to die. Without treatment the infection will only get worse and spread to other parts of the body and in some cases you can get a bacterial infection if it goes untreated.

(e,f, g ). Voriconazole has both oral and IV formulations while Posaconazole is available as an oral suspension, delayed-release tablets and, an IV formulation (h). Posaconazole doses is taken as oral suspension is taken 3 times daily or delayed-release tablet is taken once daily and IV infusion once daily (k). Voriconazole is taken as IV every 12 hours (k). A clinical trial had shown that posaconazole prevent the development of IFI more effectively compared to fluconazole or itraconazole as well as improve overall survival, but posaconazole was found to result in more serious side effects (i). One the other hand, there is no clinical trial conducted to know the effect of Voriconazole on AML patients (e). There is clinical trial conducted on patients who had hematopoietic cell transplantation, many of them have AML (j). The study compared between voriconazole versus fluconazole; there was less fungal infection (Aspergillus infections) in voriconazole group compared to fluconazole with no overall improvement in fungal-free survival period (j).

Posaconazole is a broad-spectrum antifungal against a variety of systemic and opportunistic fungal pathogens by binding to and inhibiting lanosterol-14 α-demethylase (CYP51A1). CYP51A1 can convert lanosterol to ergosterol, which is is responsible for maintaining the cellular membrane activity and integrity of fungi.

Accordingly, in vitro release rate of ketoprofen from KPT7 was the most convenient one among the previously studied tablet formulations showing an optimum lag time of 6hrs followed by a drug release after changing pH from1.2 to

The stock solution stability of leuprolide and the IS was evaluated at −20 °C for a month. The bench-top and long-term stability were evaluated to determine the stability of leuprolide in plasma samples under different conditions including bench-top stability, processed sample stability, and freeze-thaw stability. All the stability tests were performed using QC samples at two different concentrations: low (60 pg/mL) and high (8000 pg/mL). The bench-top stability was conducted using QC samples at room temperature for 12 h. The long-term stability was evaluated after the storage of the samples at −80 °C for three months. The processed sample stability was evaluated by analyzing the extracted samples in the sample injector at

It is lipid-soluble, practically insoluble in water at low pH and freely soluble in water at high pH. The octanol/water partition coefficient of naproxen at pH 7.4 is 1.6 to 1.8 (43).

Over a decades ago of the treatment of disease has been expert by customary courses specifically oral, sublingual, rectal, parental and so forth. Topical medication organization is a limited medication conveyance framework anyplace in the body through ophthalmic, rectal, vaginal and skin as topical courses. The fundamental favorable position of topical conveyance framework is to sidestep first pass digestion system. Evasion of the dangers and disservices of intravenous treatment and of the shifted states of retention like pH changes, nearness of proteins, gastric discharging time are different points of interest of topical arrangements. These are applying a wide range of arrangements for both restorative and dermatological, to their solid or unhealthy skin. Dermatological items are various in definition and reach in consistency from fluid to powder however the most prevalent items are semisolid planning. Inside the real gathering of semisolid arrangements, the utilization of straightforward gels has extended both in beautifying agents and in pharmaceutical arrangements. Gels are a generally more current class of measurements structure made by entanglement of a lot of watery or hydro alcoholic fluid in a system of colloidal strong particles. Gel definitions for the most part give quicker medication discharge contrasted and ordinary treatments and creams. Notwithstanding numerous points of interest of gels a noteworthy confinement is in the trouble in conveyance of hydrophobic

In 1995, the biopharmaceutical classification system (BCS) was introduced to classify drugs based on their aqueous solubility and gastro intestinal permeability [6]. In order to classify the drugs according to BCS, the solubility and permeability of the drug should be known.

Abuhammour and Habte-Gabr (2001) reported that, fungal infections have been classified into two distinctive classes: systemic and superficial. Consequently antifungal agents are classified under two major headings, systemic and topical agents .There are only a few systemic antifungal drugs available for use and these are polyenes (Amphotericin B), pyrimidines (Flucytosine), azoles (Ketoconazole,Fluconazole and Itraconazole) and Griseofulvin.
