Efinaconazole
Efinaconazole, sold under the brand name Jublia among others, is a triazole antifungal medication. It is approved for use in the United States, Canada, and Japan as a 10% topical solution for the treatment of onychomycosis (fungal infection of the nail). Efinaconazole acts as a 14α-demethylase inhibitor. It was approved as a generic medication in the United States in 2020. Medical uses Efinaconazole is an azole antifungal indicated in the US for the topical treatment of onychomycosis of the toenails due to ''Trichophyton rubrum'' and ''Trichophyton mentagrophytes''. Efficacy In two clinical trials 17.8% (trial 1) and 15.2% (trial 2) of participants using efinaconazole were completely cured (0% clinical involvement of the target toenail, plus negative KOH test and negative culture), compared with 3.3% (trial 1) and 5.5% (trial 2) of participants using a placebo. The "complete cure or almost complete cure" rate (≤5% affected target toenail area involved, and negative KOH and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onychomycosis
Onychomycosis, also known as tinea unguium, is a fungal infection of the nail. Symptoms may include white or yellow nail discoloration, thickening of the nail, and separation of the nail from the nail bed. Toenails or fingernails may be affected, but it is more common for toenails. Complications may include cellulitis of the lower leg. A number of different types of fungus can cause onychomycosis, including dermatophytes and ''Fusarium''. Risk factors include athlete's foot, other nail diseases, exposure to someone with the condition, peripheral vascular disease, and poor immune function. The diagnosis is generally suspected based on the appearance and confirmed by laboratory testing. Onychomycosis does not necessarily require treatment. The antifungal medication terbinafine taken by mouth appears to be the most effective but is associated with liver problems. Trimming the affected nails when on treatment also appears useful. There is a ciclopirox-containing nail polish, but t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Azole Antifungal
An antifungal medication, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others. Such drugs are usually yes obtained by a doctor's prescription, but a few are available over the counter (OTC). Types of antifungal There are two types of antifungals: local and systemic. Local antifungals are usually administered topically or vaginally, depending on the condition being treated. Systemic antifungals are administered orally or intravenously. Of the clinically employed azole antifungals, only a handful are used systemically. These include ketoconazole, itraconazole, fluconazole, fosfluconazole, voriconazole, posaconazole, and isavuconazole. Examples of non-azole systemic antifungals include griseofulvin and terbinafine.

Topical Medication
A topical medication is a medication that is applied to a particular place on or in the body. Most often topical medication means application to body surfaces such as the skin or mucous membranes to treat ailments via a large range of classes including creams, foams, gels, lotions, and ointments. Many topical medications are epicutaneous, meaning that they are applied directly to the skin. Topical medications may also be inhalational, such as asthma medications, or applied to the surface of tissues other than the skin, such as eye drops applied to the conjunctiva, or ear drops placed in the ear, or medications applied to the surface of a tooth. The word ''topical'' derives from Greek τοπικός ''topikos'', "of a place". Justification Topical drug delivery is a route of administering drugs via the skin to provide topical therapeutic effects. As skin is one of the largest and most superficial organs in the human body, pharmacists utilise it to deliver various drugs. This ...

KOH Test
The KOH Test for ''Candida albicans'', also known as a potassium hydroxide preparation or KOH prep, is a quick, inexpensive fungal test to differentiate dermatophytes and ''Candida albicans'' symptoms from other skin disorders like psoriasis and eczema. Dermatophytes are a type of fungus that invades the top layer of the skin, hair, or nails. There are three genera of fungi commonly implicated: Trichophyton (found in skin, nail, and hair infections), Epidermophyton (skin and nail infections), and Microsporum (skin and hair infections). Dermatophytes produce an infection commonly known as ringworm or tinea. It can appear as "jock itch" in the groin or inner thighs (tinea cruris); on the scalp and hair (tinea capitis) resulting in brittle hair shafts that fall out easily. Tinea unguium affects the nails and athlete's foot (tinea pedis) affects the feet. Tinea versicolor refers to a fungal infection of the skin caused by ''Malassezia furfur''. It appears anywhere on the skin and pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanosterol 14α-demethylase Inhibitors
Lanosterol is a tetracyclic triterpenoid and is the compound from which all animal and fungal steroids are derived. By contrast plant steroids are produced via cycloartenol. Role in biosynthesis of other steroids Elaboration of lanosterol under enzyme catalysis leads to the core structure of steroids. 14-Demethylation of lanosterol by CYP51 eventually yields cholesterol. Biosynthesis Research Lanosterol has been identified as a key component in maintaining eye lens clarity. Pre-clinical research has identified Lanosterol as a possible agent for the reversal and prevention of cataracts. In vivo experiments on dogs showed significant reversal of cataracts within 6 weeks of lanosterol injection. In 2018, Lanosterol was shown to improve lens clarity in cells with lens clouding due to aging or physical stressors. A subsequent study found positive results on the optics of the lens in mice with cataracts (Wang, Hoshino,Uesugi, Yagi, Pierscionek and Andley (2022). Use Lanosterol is a ...

Placebo
A placebo ( ) is a substance or treatment which is designed to have no therapeutic value. Common placebos include inert tablets (like sugar pills), inert injections (like Saline (medicine), saline), sham surgery, and other procedures. In general, placebos can affect how patients perceive their condition and encourage the body's chemical processes for relieving pain and a few other symptoms, but have no impact on the disease itself. Improvements that patients experience after being treated with a placebo can also be due to unrelated factors, such as regression to the mean (a statistical effect where an unusually high or low measurement is likely to be followed by a less extreme one). The use of placebos in clinical medicine raises ethical concerns, especially if they are disguised as an active treatment, as this introduces dishonesty into the doctor–patient relationship and bypasses informed consent. While it was once assumed that this deception was necessary for placebos to have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
