A keynote on Antifungal Agents

Antifungals are made up of various drugs that treat fungal infections. The process of antifungals consists of the hindrance of the fungal diaphragm and cellulose biosynthesis, modification of fungal diaphragm, impact on tubulin, and obstruction of nucleic acid biosynthesis. These antifungal agents further have two divisions: systemic and topical. 

Various systemic antifungals are harmful to human cells. On the contrary, due to weak penetrations of topical antifungals, these affect the whole body rather than a particular site. These are further categorised into two: imidazole and triazoles. Some systemic antifungals include triazole like ketoconazole; and imidazole like clotrimazole, miconazole etc. 

Explanation of the Key Terms Related to the Topic

Fungal Infections

Fungal infections are also referred to as Mycosis. Most fungi are innocuous to individuals, yet a few types of fungus can lead to illness under some particular conditions. The fungus proliferates by liberating spores, which are easy to pick up by direct communication or breathing. Therefore, these infections are commonly observed on the dendrums like (skin or nails) and lungs. Commonly observed fungal infections are:

1. athlete’s foot
2. jock itch
3. ringworm
4. yeast infection
5. onychomycosis, or fungal infection of the nail

Antifungal Agents

Antifungal agents mainly fight infections in individuals with impaired immune systems and post-transplant infections. The process of antifungals consists of the hindrance of the fungal diaphragm and cellulose biosynthesis, modification of fungal diaphragm, impact on tubulin, and obstruction of nucleic acid biosynthesis. 

Types of Antifungal Agents

There are two antifungal divisions: systemic (categorised in three subdivisions as per their clinical use – azoles, polyenes, and allylamines) and topical (also categorised in three subdivisions as per their clinical use – triazoles, polyenes, and echinocandins). 

Topical triazoles like ketoconazole, a considerable division of antifungals, indicate a deteriorating capacity to show the desired results because of the evolution of such fungal infection, which is drug-resistant. That is why echinocandins came into practice. Systemic Azoles, like imidazole, have two nitrogen atoms, including Clotrimazole and Miconazole.

How are Fungal Infections Diagnosed?

Diagnosing a fungal infection initiates with a physical examination and exposure to the symptoms. A skin-type fungal infection may be diagnosed by taking a sample of the skin, hair, or nail tested at a lab. For other fungal infections, a doctor may collect a sample of bodily fluids, like blood, urine, cerebrospinal fluid, vaginal secretions or sputum. Sometimes a tissue sample, called a biopsy, may be taken from the targeted organ. An X-ray is preferred to check fungal traces and damaged tissue in the respiratory system.

How are Fungal Infections Cured?

Fungi results in causing rashes and other severe effects on the dendrums (nails or skin). It can result in severe issues such as meningitis (a risky illness-causing swelling in the meninges, generally caused by some bacterial infection or viral). Common symptoms include severe headaches, high body temperature, rigid muscles, sensitivity to light, and infections in the lungs or blood. Therefore, the following antifungals are used to cure it.

Ketoconazole

Ketoconazole is used for curing particular fungal infections in individuals. It relates to the azole antifungals. However, it is not suitable to cure skin and nails related fungal infections because of its adverse side effects.

One is advised to consume it orally under the guidance of a physician, generally preferred with food to avoid stomach issues. Individuals are typically advised to inform the doctor prior if they are allergic to any drug.

Clotrimazole

Clotrimazole is used to cure skin infections such as ringworm, jock itch, candidiasis, pityriasis etc. It is advisable only for the skin after completely cleaning and drying the targeted area. It is advised not to use clotrimazole on sensitive areas. The improper course of this medicine may cause a relapse of the illness. 

One should inform the physician if the issue continues even after the completion of four weeks of illness, or if things go out of control. Some side effects of Clotrimazole include itching, swelling, rashes, redness, pimple-like bumps etc.

Miconazole

Miconazole is used to cure vaginal yeast infections, which tend to cause burning, irritation, and whitewash. Miconazole is an azole antifungal that resists the rise of fungus yeast.

There are two vaginal products for treating this cure: cream and tablet. Use of this drug is strictly advised to be used under the supervision of an expert. This medicine is avoided if the symptoms like fever, flu, abdominal pain, or a nasty vaginal discharge are observed.

Conclusion

So, it is now known that fungus, which is increased by liberating spores, is easy to pick up by direct communication or breathing. Therefore, these infections are commonly observed on the dendrums like (skin or nails) and lungs. Some fungi can easily affect individuals with poor immunity systems. So, antifungal agents are mainly in practice to fight these infections, especially in individuals with impaired immune systems and post-transplant infections. Some commonly used antifungal agents are ketoconazole, clotrimazole, and miconazole.
