Indications

Clotrimazole is a synthetic imidazole with a broad spectrum of antimycotic activity.[1] Clotrimazole is an FDA-approved drug to treat oral candidiasis, vaginal candidiasis, and dermatomycoses. Clotrimazole is effective in the treatment of skin infections such as athlete’s foot, jock itch, ringworm, pityriasis versicolor, intertrigo, and erythrasma.[2][3]

In addition, clotrimazole has some activity against certain gram-positive bacteria, and at very high concentrations, has activity against Trichomonas spp.[4] In adults and children older than 12 years, the FDA has approved the use of clotrimazole in combination with betamethasone propionate (corticosteroid) for the topical treatment of inflammatory tinea due to Epidermophyton floccosum and Trichophyton. However, caution should be exercised, as the use of such combinations can aggravate fungal infections.[5]

Mechanism of Action

Clotrimazole exerts its action primarily by damaging the permeability barrier in the fungal cytoplasmic membrane. [6] Clotrimazole thereby inhibits the biosynthesis of ergosterol in a concentration-dependent manner by inhibiting the demethylation of 14 alpha lanosterol.[7] When ergosterol synthesis becomes inhibited, the cell can no longer construct an intact and functional cell membrane.[8] Ergosterol also directly promotes the growth of fungal cells in a hormone-like fashion; therefore, the rapid onset of the above events leads to a dose-dependent inhibition of fungal growth.

Though clotrimazole exerts its anti-fungal action by decreasing ergosterol biosynthesis, clotrimazole exerts other pharmacological actions. 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.[9][10] Such action of clotrimazole on different cell targets accounts for other effects of this drug that are separate from its antimycotic activities.[1]

Administration

Clotrimazole is available as topical lotions, powders, oral lozenges, and vaginal inserts/tablets under various tradenames approved by the FDA.

Oral Administration of Other Oral Formulations

• Transmucosal administration

• Patients should slowly dissolve troches in the mouth, do not chew.

Topical Administration Cream/Ointment/Lotion Formulations

• Rub cream or solution gently into the cleansed affected skin.

• Topical preparations should not be used in the eye; or used intravaginally.

Intravaginal Administration

Intravaginal application is only for those clotrimazole products labeled for intravaginal use. Some commercially available preparations contain both intravaginal tablets and vaginal cream in a combination package.  The intravaginal cream may be applied externally to the affected area (vulva) to relieve itching and discomfort.

Use a special applicator supplied by the manufacturer.

Instruct patients on proper administration and treatment courses.

Patients should not use tampons, douches, or spermicides during treatment. The patient should also receive instruction to abstain from sexual activity during treatment. Vaginal clotrimazole products may cause damage to condoms, diaphragms, and cervical caps and cause them to fail.

Vaginal Dosage (vaginal cream) Adult Females

• One applicatorful of 1% cream (50 mg) vaginally for seven days or one applicatorful of 2% cream (100 mg) vaginally for three days, applied at bedtime.

• External application of the cream may also is an option if there are extra-vaginal symptoms. Guidelines recommend treatment for seven days for pregnant patients and 7 to 14 days for immunocompromised patients.[11][12]

Adolescent Females 12 to 17 years

• Apply one applicatorful of 1% cream (50 mg) vaginally for seven days or one applicatorful of 2% cream (100 mg) vaginally at bedtime for three days. External application of the cream may also are an option if there are extra-vaginal symptoms. Guidelines recommend treatment for seven days for pregnant patients and 7 to 14 days for immunocompromised patients.

For the Treatment of Oropharyngeal Candidiasis (thrush) Transmucosal Dosage

Children and Adolescents 3 to 17 years

For the Treatment of Tinea Versicolor Topical

Adults

• Apply to the affected skin and surrounding areas twice daily, both morning and evening.

Children and Adolescents

• Apply to the affected skin and surrounding areas twice daily, both morning and evening.

Adverse Effects

The adverse effects of oral formulation include itching, nausea, and vomiting. More than 10% of patients using the oral formulation may have abnormal liver function tests. For this reason, liver function tests should have periodic monitoring when taking oral clotrimazole (troche). When using clotrimazole to treat vulvovaginal candidiasis, <10% of patients have a vulvar or vaginal burning sensation. Other side effects include rash, hives, blisters, burning, itching, peeling, redness, swelling, pain, or other signs of skin irritation. [14] For topical formulations, it should be used externally and discontinued if irritation or sensitivity develops at the administration site.

Contraindications

Onychomycosis

Topical clotrimazole is not effective for onychomycosis. Therefore, fungal nail infections usually require treatment with an oral (systemic) antifungal drug.

Pregnancy

Clotrimazole demonstrates poor absorption after dermal or intravaginal administration. Only topical preparations are recommended in pregnancy.[15] There are inadequate well-controlled human studies with the use of topical or intravaginal clotrimazole during the first trimester of pregnancy clotrimazole should only be used if indicated.[16] However, clinical trials showed intravaginal clotrimazole to be safe in clinical trials during the second and the third trimester of pregnancy and are recommended for use.[17][12] 

Clotrimazole is not known to cross the placenta.[11] FDA classifies clotrimazole as a class C drug in pregnancy risk classification. There are no adequate, well-controlled studies for oral clotrimazole in pregnant women. There have been no teratogenic effects demonstrated after clotrimazole therapy in pregnancy.[17] In animal studies with dosing up to 200 times the human dose, doses of 100 times the adult human dose have been embryotoxic in rats and mice. There are well-controlled studies in humans; hence the use of oral clotrimazole lozenges during pregnancy should only be an option if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

The use of clotrimazole during breastfeeding has not been studied. No data is available about the excretion of clotrimazole in breast milk. Topical clotrimazole poses little risk to nursing infants as topical clotrimazole is not expected to result in significant maternal absorption.[18] Instruct mothers not to apply clotrimazole topically to the breast during times of breastfeeding. The oral troches should be used only when needed, as this may be systemically absorbed. Report to the FDA if a breastfeeding infant experiences any adverse effects.

Contraceptive Devices, Menstruation

Patients should abstain from sexual intercourse during the treatment course. With intravaginal clotrimazole preparations, contraceptive failures can occur during the treatment due to the damage of contraceptive devices such as diaphragms, condoms, and cervical caps. In addition, tampon use is not advisable while using clotrimazole during menstruation.

Azole Antifungals Hypersensitivity

Patients with azole antifungals hypersensitivity should avoid using clotrimazole. Hypersensitivity reactions commonly occur due to the components in the formulation present in different clotrimazole preparations.

Ocular Exposure, Ophthalmic Administration

If eye contact with clotrimazole occurs, treat immediately by flushing the affected eye with cool, clean water. Contact an ophthalmologist if eye irritation persists.

Drug-drug Interactions

Clotrimazole therapy may result in a significant rise in tacrolimus levels, leading to tacrolimus-associated toxicities. Hence caution should be exercised.[19]

Monitoring

Clotrimazole is not for systemic administration; it is administered via oral/transmucosal lozenges (troches), either topically or intravaginally. Small quantities absorbed are metabolized in the liver and excreted in the bile.

Oral Route

Transmucosal Route – clotrimazole oral lozenges are used for local treatment and are not significantly bioavailable. Concentrations persisting in saliva appear to be due to clotrimazole binding to the oral mucosa.

Topical Route

There is minimal systemic absorption following topical application of clotrimazole.

Other Routes

Intravaginal Route – roughly 5 to 10% of clotrimazole undergoes absorption following vaginal use. Therefore, fungicidal concentrations can persist in the vagina for up to 3 days after application.

Toxicity

When clotrimazole is applied locally and topically, toxic effects such as pelvic cramps, hives, skin rash, occasional headache, itching, and irritation of the vulva and vagina may be observed. Stop the medication if there are any adverse effects.

Enhancing Healthcare Team Outcomes

With any atypical symptoms, careful evaluation and reassessment should take place before prescribing or dispensing clotrimazole. Vaginal candidal infections can co-exist with other sexually transmitted infections. Hence symptoms such as foul-smelling vaginal discharge, abdominal pain, or fever higher than 100 degrees F may indicate another vaginal infection or pelvic inflammatory disease. 

The clinician or the nurse practitioner should also counsel the patient on the importance of reading labels to understand the possible side effects and avoid drug-related toxicities due to overdosing. Pharmacists should also check for any associated drug interactions and inform the prescriber and the patient of any concerns. Clinicians, nurses, physician assistants, and pharmacists should cooperate with interprofessional team strategies to advance appropriate antifungal treatment, identify warning signs of serious illness, and improve health outcomes.  [level 5]

Pharmacological action

Pharmacological action –

antibacterial , broad spectrum antifungal , antiprotozoal , trichomonacid .

Characteristics

Antifungal agent for local use from the group of imidazole derivatives.

Odorless white crystalline substance. Practically insoluble in water, sparingly soluble in ether, very soluble in polyethylene glycol 400, ethanol and chloroform. Molecular weight 344.84.

Pharmacology

It disrupts the synthesis of ergosterol (the main structural component of the cell membrane of fungi), changes the permeability of the fungal membrane, promotes the release of potassium, intracellular phosphorus compounds from the cell and the breakdown of cellular nucleic acids. Inhibits the synthesis of triglycerides and phospholipids. It reduces the activity of oxidative and peroxidase enzymes, as a result of which the intracellular concentration of hydrogen peroxide rises to a toxic level, which contributes to the destruction of cell organelles and leads to cell necrosis. Depending on the concentration, it exhibits a fungicidal or fungistatic effect. Inhibits blastospore transformation Candida albicans into an invasive mycelial form.

Clotrimazole acts mainly on growing and dividing microorganisms. In vitro exhibits fungicidal and fungistatic activity against dermatomycetes (Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, Microsporum canis), yeast-like fungi Candida spp. (including Candida albicans ). Active against the causative agent of multi-colored lichen – Pityrosporum orbiculare (Malassezia furfur).

Fungal strains naturally resistant to clotrimazole are rare. Primary resistance to clotrimazole has only been described for Candida guillermondii.

Effective against gram-positive bacteria – the causative agent of erythrasma Corynebacterium minutissimum, and Staphylococcus spp., Streptococcus spp., gram-negative bacteria – Bacteroides, Gardnerella vaginalis. In high concentrations, it is active against Trichomonas vaginalis.

Poorly absorbed through the skin and mucous membranes.

Accumulates in the stratum corneum of the epidermis, the concentration in the deep layers of the epidermis is higher than the MIC for dermatomycetes. When applied to the nails, it is found in keratin.

When administered intravaginally, 3-10% of the dose is absorbed.

Rapidly biotransformed in the liver to inactive metabolites and excreted in faeces. Absorbed clotrimazole induces the activity of microsomal liver enzymes, which leads to an acceleration of its catabolism.

High concentrations in vaginal secretion and low concentrations in the blood persist for 48-72 hours

Carcinogenicity, mutagenicity, effects on fertility . Long-term studies in animals to evaluate the potential carcinogenicity of clotrimazole when administered intravaginally have not been conducted.

A mutagenicity study in Chinese hamsters that received 5 oral doses of clotrimazole at 100 mg/kg did not reveal a mutagenic effect – structural changes during metaphase in spermatophore chromosomes.

Pregnancy. In studies in pregnant rats, intravaginal doses of clotrimazole up to 100 mg/kg showed no adverse effect on the fetus. However, daily oral doses of clotrimazole at doses of 50 to 120 mg/kg resulted in embryotoxicity in rats and mice (possibly secondary to maternal toxicity). So, in mice, when taking clotrimazole in doses 120 times higher than the usual dose in humans, in the period from 9 weeks to mating and until the end of feeding, mating disorders, a decrease in the number of viable cubs, and a decrease in the survival rate of offspring from birth to the end of feeding were recorded. At doses up to 60 times the usual human dose, no adverse effects were observed. In rats at doses 50 times the usual dose in humans, clotrimazole, with a similar observation period, caused a slight decrease in the number of pups in the offspring and a decrease in their survival. There was no teratogenic effect in mice, rabbits and rats when taking clotrimazole orally at doses up to 200, 180 and 100 mg/kg, respectively.

Application of the substance Clotrimazole

Fungal infections of the skin and mucous membranes: ringworm, dermatophytosis, trichophytosis, epidermophytosis, microsporia, candidiasis, interdigital fungal erosion, fungal paronychia; mycoses complicated by secondary pyoderma; versicolor versicolor, erythrasma; candidiasis stomatitis; candidal vulvitis, vulvovaginitis, balanitis, trichomoniasis; for sanitation of the birth canal before childbirth.

Contraindications

Hypersensitivity.

Use in pregnancy and lactation

Should not be used in the first trimester of pregnancy (no adequate and well-controlled studies have been conducted). With intravaginal use in women in the II and III trimesters of pregnancy, no adverse effects on the fetus have been identified, however, the use of a vaginal applicator is undesirable.

With caution – during breastfeeding (it is not known whether clotrimazole passes into breast milk).

Side effects of the substance Clotrimazole

Allergic reactions (itching, urticaria).

When applied topically to the skin: erythema, blistering, swelling, burning and stinging, skin irritation and flaking.

When applied topically to treat urogenital infections: itching, burning, hyperemia and swelling of the mucous membrane, vaginal discharge, frequent urination, intercurrent cystitis, burning sensation in the partner’s penis, pain during intercourse.

Topically applied in the mouth: redness of the oral mucosa, burning and tingling sensation at the site of application, irritation.

Interaction

Reduces the activity (mutually) of polyene antibiotics (amphotericin B, nystatin, natamycin).

Overdose

In case of accidental ingestion of drugs, the following symptoms are possible: anorexia, nausea, vomiting, gastralgia, impaired liver function; rarely – drowsiness, hallucinations, pollakiuria, allergic skin reactions.

Treatment: activated charcoal, symptomatic therapy.

Dosage and Administration

Locally, is applied in a thin layer to the affected areas of the skin and mucous membranes 2-4 times a day. The course of treatment is selected individually, usually at least 4 weeks; upon its completion (disappearance of clinical manifestations), it is advisable to continue using the drug for another 14 days. The duration of therapy for erythrasma is 2-4 weeks, for lichen multi-colored – 1-3 weeks.

Before greasing, wash the feet with warm water and soap, dry thoroughly, especially between the toes. In fungal diseases of the skin of the legs, it is recommended to continue treatment after achieving a therapeutic effect for 2-3 weeks.

Topical in the oral cavity: 10-20 drops (0.5-1 ml) of topical solution are applied to the affected areas of the oral mucosa with a cotton swab/stick 3-4 times a day. Improvement usually occurs on the 3rd-5th day of treatment; treatment should be continued until the complete elimination of the clinical manifestations of the disease.

Locally for urogenital infections. For candidal vulvitis or balanitis, use 2-3 times a day for 1-2 weeks. For the treatment of trichomoniasis, vaginitis in adults and adolescents: vaginal tablets (500 mg once or 200 mg for 3 days or 100 mg for 6-7 days, once a day, in the evening), or cream (full applicator) is administered as soon as possible deeper into the vagina 1 time per day (before going to bed). For the rehabilitation of the birth canal, a single administration of the tablet is recommended.

For urethritis, instillation of 1% clotrimazole solution into the urethra is also carried out for 6 days.

Precautions

Avoid contact with the mucous membrane of the eyes. Avoid application on areas with violation of the integrity of the skin.

Do not use sealing dressings after applying the cream.

Simultaneous treatment of the sexual partner is recommended to prevent reinfection. Do not prescribe intravaginally during menstruation. With trichomoniasis, a combined intake with systemic chemotherapeutic agents (metronidazole orally) is recommended.

In patients with impaired liver function, it is necessary to periodically monitor its functional state.

The appearance of irritation or signs of hypersensitivity requires discontinuation of treatment.

If there is no clinical improvement within 4 weeks, a microbiological examination should be performed to confirm the diagnosis and exclude another cause of the disease.
