Clotrimazole is a broad spectrum antifungal. It also exhibits activity against Trichomonus, Staphylococci, Streptococci and Bacteroides. Clotrimazole 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. Clotrimazole 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).
Clotrimazole 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 .
Clotrimazole 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 .
Mometasone is a corticosteroid demonstrating anti-inflammatory properties. The precise mechanism of corticosteroids action on allergic rhinitis is not known. Corticosteroids have been shown to have a wide range of effects on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in inflammation.
Mometasone is a medium-potency synthetic corticosteroid with antiinflammatory, antipruritic, and vasoconstrictive properties. Studies in asthmatic patients have demonstrated that mometasone provides a favorable ratio of topical to systemic activity due to its primary local effect along with the extensive hepatic metabolism and the lack of active metabolites. Though effective for the treatment of asthma, glucocorticoids do not affect asthma symptoms immediately. Maximum improvement in symptoms following inhaled administration of mometasone furoate may not be achieved for 1 to 2 weeks or longer after starting treatment. When glucocorticoids are discontinued, asthma stability may persist for several days or longer. Mometasone has been shown in vitro to exhibit a binding affinity for the human glucocorticoid receptor which is approximately 12 times that of dexamethasone, 7 times that of triamcinolone acetonide, 5 times that of budesonide, and 1.5 times that of fluticasone. The clinical significance of these findings is unknown.

How Metacortil C works
Clotrimazole acts primarily by damaging the permeability barrier in the cell membrane of fungi. Clotrimazole 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 .
Unbound corticosteroids cross cell membranes and bind with high affinity to specific cytoplasmic receptors. Inflammation is decreased by diminishing the release of leukocytic acid hydrolases, prevention of macrophage accumulation at inflamed sites, interference with leukocyte adhesion to the capillary wall, reduction of capillary membrane permeability, reduction of complement components, inhibition of histamine and kinin release, and interference with the formation of scar tissue. The antiinflammatory actions of corticosteroids are thought to involve phospholipase A2 inhibitory proteins, lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes. Mometasone furoate has been shown in vitro to exhibit a binding affinity for the human glucocorticoid receptor which is approximately 12 times that of dexamethasone, 7 times that of triamcinolone acetonide, 5 times that of budesonide, and 1.5 times that of fluticasone.
Dosage
Metacortil C 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. For Athlete’s foot, pay special attention to the spaces between the toes. Best results in Athlete's foot and ringworm are usually obtained with 4 weeks use of this product. The cream should be applied two or three times daily for one month or for at least two weeks after the disappearance of all signs of infection. If satisfactory results have not occurred within these times consultation with doctor is essential. For best results, follow directions and continue treatment for length of time indicated. The duration of treatment varies; it depends among other factors on the extent and localization of the disease.
Recommended duration of treatment :
- Dermatomycoses: 3-4 weeks
- Candida vulvitis and candida balanitis: 1-2 weeks
- Erythrasma and pityriasis versicolor (approx.): 3 weeks
- In fungal infection of the feet, to prevent relapses:Treatment should be continued for about 2 weeks beyond the disappearance of all signs of disease.
Clotrimazole cream is odourless, can be washed off and does not stain.
Rectal
First infections: In general, a 3-day treatment is sufficient for Candida vaginitis. On 3 consecutive nights, Clotrimazole 200 mg vaginal preparation is inserted as deeply as possible into the vagina. This is best achieved when lying on one's back with the knees slightly bent.
Re-infections: In general, a 6-day treatment is sufficient. This applies also to mixed infections with the above-mentioned causative organisms. On six consecutive nights, 1 Clotrimazole 100 mgvaginal preparation is inserted as deeply as possible into the vagina. If necessary, 2 Clotrimazole 100 mg(1 in the morning and 1 in the evening) or 1 Clotrimazole 200 mg daily can be used for 6-12 days. Treatment should be timed so as to avoid the menstrual period and be finished before the onset of menstruation. To avoid re-infection, the partner should undergo local treatment with Clotrimazole cream at the same time.
Clotrimazole 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 Clotrimazole cream at the same time.
Clotrimazolevaginal 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 Clotrimazole 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.
A thin film of Mometasone Furoate cream should be applied to the affected skin areas once daily.Safety and effectiveness in paediatric patients below 2 years of age have not been established.
For the treatment to become a complete success, reliable and sufficiently long application of Clotrimazole cream is important. The duration of treatment varies; it depends among other factors on the extent and localisation of the disease.
Side Effects
Clotrimazole 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 Clotrimazole absorption through the vaginal skin, no systemic effect is expected. The local tolerance of Clotrimazole 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.
Mometasone Furoate cream is generally well tolerated. Burning, Pruritus and skin atrophy may occur.
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;
Overdose
This drug poses no risk of acute intoxication, as it is unlikely to occur following a single vaginal or dermal application of an overdose (application over a large area under conditions favorable to absorption) or accidental oral ingestion. There is no specific antidote .
Effects on Fertility
No human studies of the effects of clotrimazole on fertility have been conducted; however, animal studies have not shown any effects on the drug on fertility .
Use in Pregnancy
There are limited data regarding the use of clotrimazole in pregnant women. Animal studies do not show direct or indirect harmful effects on reproduction. Although the topical application of clotrimazole may result in very low serum and tissue levels, the use of clotrimazole topical cream by pregnant women is not recommended unless it is advised by the prescribing physician. Clotrimazole topical cream should not be used in the first trimester of pregnancy unless it is considered by the physician to be essential to patient well-being .
Use in Breastfeeding
Available pharmacodynamic/toxicological studies in animals have shown excretion of clotrimazole/metabolites in breastmilk. Clotrimazole should not be administered during breastfeeding. Although the topical application of clotrimazole has resulted in very low serum and tissue levels, the use of clotrimazole topical cream by lactating women is not recommended unless it recommended by the prescribing physician .
The potential for acute toxic effects following overdose with the mometasone inhaler is low. However, habitual overuse of the product can cause symptoms of steroid overload, including menstrual irregularities, acne, obesity, and muscle weakness. Single oral doses up to 8000 µg have been studied on human volunteers with no adverse events reported.
Precaution
If local intolerance develops, consider withdrawal of the medicine and institution of appropriate therapy. Clotrimazole solution is not intended for ophthalmic use. Avoid contact with eyes upon topical application. Children 3 yrs. Pregnancy, lactation. If irritation or sensitivity develops with the use of Clotrimazole ointment, treatment should be discontinued.
If irritation develops with the use of Mometasone Furoate cream, treatment should be discontinued.
Interaction
There have been reports of a heat reaction when this medication used concomitantly with Sofradex drops in the ear.
