Clarizol

Clarizol Uses, Dosage, Side Effects, Food Interaction and all others data.

Clarizol is a broad spectrum antifungal. It also exhibits activity against Trichomonus, Staphylococci, Streptococci and Bacteroides. Clarizol kills fungi and yeasts by interfering with their cell membranes. It works by stopping the production of ergosterol, which is an essential component of fungal cell membranes resulting in increased membrane permeability and leakage of essential constituents of the fungal cells. Clarizol acts reliably on dermatophytes, yeasts and other fungi; it is also effective against Trichomonas vaginalis and Gram-positive microorganisms (streptococci/ staphylococci) and Gram-negative microorganisms (bacteroides/ Haemophilus vaginalis).

Clarizol is a broad-spectrum antifungal agent that inhibits the growth of pathogenic yeasts by changing the permeability of cell membranes. The action of clotrimazole is fungistatic at concentrations of drug up to 20 mcg/mL and may be fungicidal in vitro against Candida albicans and other species of the genus Candida at higher concentrations . Unfortunately, resistance to clotrimazole, which was rare in the past, is now common in various patient populations .

Clarizol is generally considered to be a fungistatic, and not a fungicidal drug, although this contrast is not absolute, as clotrimazole shows fungicidal properties at higher concentrations .

Uses

The confirmed indication for Clarizol include:

  • All dermatomycoses due to dermatophytes (e.g. Trichophyton species).
  • All dermatomycoses due to yeasts (Candida species).
  • Dermatomycoses due to moulds and other fungi.
  • Skin diseases showing superinfections with these fungi.

To the dermatomycoses listed under 1-4 belong for example, interdigital myocoses (e.g. athlete’s foot), paronychias (associated with nail mycoses), myocoses in skin folds, Candida vulvitis, Candida balanitis, Pityriasis versicolor, erythrasma.

Clarizol rectal preparation is used for vaginal itching, burning and discharge associated with recurrent vaginal yeast infections (Vaginal candidiasis) and also in viginitis due to Candida species as well as Mycotic infections complicated by other microorganisms sensitive to the drug.

Clarizol Sterile Eye Ointment is used for the treatment of fungal keratitis due to filamentous fungi and Candida species.

Clarizol Ear Drop is used for the treatment of fungal infections of the ear.

How Clarizol works

Clarizol acts primarily by damaging the permeability barrier in the cell membrane of fungi. Clarizol causes inhibition of ergosterol biosynthesis, an essential constituent of fungal cell membranes. If ergosterol synthesis is either completely or partially inhibited, the cell is no longer able to construct an intact and functional cell membrane ,. Because ergosterol directly promotes the growth of fungal cells in a hormone‐like fashion, rapid onset of the above events leads to dose-dependent inhibition of fungal growth .

Though decreased ergosterol, due to the inhibition of lanosterol 14-demethylase (also known as CYP51) is accepted to be primarily responsible for the antimycotic properties of clotrimazole, this drug also shows other pharmacological effects. These include the inhibition of sarcoplasmic reticulum Ca2+‐ATPase, depletion of intracellular calcium, and blocking of calcium‐dependent potassium channels and voltage‐dependent calcium channels . The action of clotrimazole on these targets accounts for other effects of this drug that are separate from its antimycotic activities .

Dosage

Clarizol dosage

Topical

Wash skin with soap and water and dry thoroughly. Apply a thin layer of the cream or solution 2-3 times daily and gently massage over affected area as directed by the doctor.

Clarizol 500 mg vaginal preparation: Single dose, complete treatment with one vaginal tablet. The tablet should be inserted as deeply as possible into the vagina. This is best achieved when lying on one's back with the knees slightly bent. It is recommended that the treatment should be timed so as to avoid the menstrual period. For prevention of re-infection the partner should be treated locally with Clarizol cream at the same time.

Clarizolvaginal preparation are colorless and do not stain the underwear.

Eye

Adult: It should be applied thinly and evenly to the conjunctival sac every 4 hours daily or as advised by a physician.

Children: Safety and effectiveness in children have been established for Clarizol when used as indicated and in the recommended dosage.

Ear

Instill 2-3 drops of Clarizol Ear Drops in the affected ear two or three times daily.The treatment should be continued for at least two weeks after the disappearance of all signs of infection to prevent re-infection.

For the treatment to become a complete success, reliable and sufficiently long application of Clarizol cream is important. The duration of treatment varies; it depends among other factors on the extent and localisation of the disease.

Side Effects

Clarizol is generally well tolerated after local application but the few side effects have been reported infrequently like erythema, stinging, blistering, peeling, oedema, pruritus, urticaria and general irritation.

Since there is practically no Clarizol absorption through the vaginal skin, no systemic effect is expected. The local tolerance of Clarizol vaginal tablet is generally good. Local irritation or burning sensation may occur in a very few cases but these symptoms are not considered harmful.

Rarely patients may experience burning or irritation immediately after applying the ointment.

Toxicity

Symptoms of overdose include erythema, stinging, blistering, peeling, edema, pruritus, urticaria, burning, and general irritation of the skin, and cramps. As with all topical agents, skin sensitization may result .

Oral LD50 (rat): 708 mg/kg; Intraperitoneal LD50 (rat): 445 mg/kg; Subcutaneous LDLO (rat): 10 g/kg; Oral LD50 (mouse): 761 mg/kg; Subcutaneous LDLO (mouse): 10 g/kg; Intraperitoneal LD50 (mouse): 108 mg/kg;
