Uses

The confirmed indication for Clotrimazole 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.

Clotrimazole 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.

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

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

Miconazole Topical Cream has an antibacterial effect on Gram-positive bacteria, it may be used in mycoses secondarily infected with such bacteria. Skin and nail infections due to dermatophytes, yeasts and other fungi such as: Tinea capitis, corporis, manuum, pedis, barbae, cruris, unguium or onychomycosis. Pityriasis versicolor, candidiasis of skin and nails, stomatitis angularis, otitis externa.

Miconazole Oral treatment and prevention of fungal infections of the oropharynx and gastrointestinal tract, and of super infections due to Gram-positive bacteria.

Trichomoniasis: Tinidazole is used for the treatment of trichomoniasis caused by Trichomonas vaginalis. The organism should be identified by appropriate diagnostic procedures. Because trichomoniasis is a sexually transmitted disease with potentially serious sequelae, partners of infected patients should be treated simultaneously in order to prevent re-infection.

Giardiasis: Tinidazole is used for the treatment of giardiasis caused by Giardia duodenalis in both adults and pediatric patients older than three years of age. Sections or subsections omitted from the full prescribing information are not listed.

Amebiasis: Tinidazole is used for the treatment of intestinal amebiasis and amebic liver abscess caused by Entamoeba histolytica in both adults and pediatric patients older than three years of age. It is not used for the treatment of asymptomatic cystpassage.

Bacterial Vaginosis: Tinidazole is used for the treatment of bacterial vaginosis (formerly referred to as Haemophilus vaginitis, Gardnerella vaginitis, nonspecific vaginitis, or anaerobic vaginosis) in non-pregnant women.

Other pathogens commonly associated with vulvovaginitis such as Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhoeae, Candida albicans and Herpes simplex virus should be ruled out.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Tinidazole and other antibacterialdrugs, Tinidazole should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

How Tmc Vag 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 .

Miconazole is an azole antifungal used to treat a variety of conditions, including those caused by Candida overgrowth. Unique among the azoles, miconazole is thought to act through three main mechanisms. The primary mechanism of action is through inhibition of the CYP450 14α-lanosterol demethylase enzyme, which results in altered ergosterol production and impaired cell membrane composition and permeability, which in turn leads to cation, phosphate, and low molecular weight protein leakage.

In addition, miconazole inhibits fungal peroxidase and catalase while not affecting NADH oxidase activity, leading to increased production of reactive oxygen species (ROS). Increased intracellular ROS leads to downstream pleiotropic effects and eventual apoptosis.

Lastly, likely as a result of lanosterol demethylation inhibition, miconazole causes a rise in intracellular levels of farnesol. This molecule participates in quorum sensing in Candida, preventing the transition from yeast to mycelial forms and thereby the formation of biofilms, which are more resistant to antibiotics. In addition, farnesol is an inhibitor of drug efflux ABC transporters, namely Candida CaCdr1p and CaCdr2p, which may additionally contribute to increased effectiveness of azole drugs.

Tinidazole is a prodrug and antiprotozoal agent. The nitro group of tinidazole is reduced in Trichomonas by a ferredoxin-mediated electron transport system. The free nitro radical generated as a result of this reduction is believed to be responsible for the antiprotozoal activity. It is suggested that the toxic free radicals covalently bind to DNA, causing DNA damage and leading to cell death. The mechanism by which tinidazole exhibits activity against Giardia and Entamoeba species is not known, though it is probably similar.

Dosage

Tmc Vag 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.

For oral administration: Dosage is based on 15 mg/kg/day.

• Adults: 1-2 tea-spoonfuls of gel four times daily
• Children aged 6 years and over: One tea-spoonful of gel four times daily
• Children aged 2-6 years: One tea-spoonful of gel twice daily
• Infants under 2 years: Half tea-spoonful of gel twice daily.

For localised lesions of the mouth:

A small amount of gel may be applied directly to the affected area with a clean finger. For topical treatment of the oropharynx, the gel should be kept in the mouth for as long as possible. Treatment should be continued for up to 2 days after the symptoms have cleared.

For oral candidasis, dental prostheses:

Should be removed at night and brushed with the gel.

The dosage is same for all the ages.

For skin infections: Apply some cream to the lesions twice daily and rub it well with finger until it has fully penetrated the skin. All lesions usually disappear after 2 to 5 weeks. Prolong treatment for some 10 days to prevent relapse.

For nail infections: Clip infected nail as shortly as possible. Apply some cream once daily to the infected nail and rub with your finger, cover nail with a non-perforated occlusive plastic bandage.

Also after loosening of the infected nail (from 2-3 weeks onwards) uniterrupted treatment should be continued until the growth of a new nail has set in and definite cure can be observed (usually after seven months or more).

Prevention of Postoperative Infections :

• Adult: A single oral dose of 2g approximately 12 hours before surgery.
• Children less than 12 years: Data are not available to allow dosage recommendations for children below the age of 12 years in the prophylaxis of anaerobic infections.

Trichomoniasis: a single 2 g oral dose taken with food. Treat sexual partners with the same dose and at the same time Giardiasis:

• Adults: a single 2 g dose taken with food.
• Pediatric patients older than three years of age: a single dose of 50 mg/kg (up to 2 g) with food

Amebiasis, Intestinal:

• Adults: 2 g per day for 3 days with food.
• Pediatric patients older than three years of age: 50 mg/kg/day (up to 2 g per day) for 3 days with food

Amebic liver abscess:

• Adults: 2 g per day for 3-5 days with food.
• Pediatric patients older than three years of age: 50 mg/kg/day (up to 2 g per day) for 3-5 days with food

Bacterial vaginosis: Non-pregnant, adult women: 2 g once daily for 2 days taken with food, or 1 g once daily for 5 days taken with food.

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.

Should be taken with food. Take during or immediately after meals.

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.

Topical application of Miconazole Nitrate has almost no side effect.

For oral gel: Occasionally, nausea and vomiting have been reported, and with long term treatment, diarrhoea. In rare instances, allergic reactions have been reported. There are isolated reports of hepatitis, for which the causal relationship with Miconazole has not been established.

Reported side effects have generally been infrequent, mild and self-limiting. Side effects from the gastrointestinal tract include nausea, vomiting, anorexia, diarrhoea and metallic taste. Hypersensitivity reactions, occasionally severe, may occur in rare cases in the form of skin rash, pruritis, urticaria and angioneurotic oedema. As with related compounds, tinidazole may produce transient leukopenia. Other rarely reported side-effects are headache, tiredness, furry tongue and dark urine.

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 .

Miconazole overdose has not been reported. Patients experiencing an overdose are at an increased risk of severe adverse effects such as headache, skin irritation, diarrhea, nausea, vomiting, abdominal pain, and dysgeusia. Symptomatic and supportive measures are recommended.

Miconazole has an oral LD₅₀ of 500 mg/kg in rats.

There are no reported overdoses with tinidazole in humans. In acute studies with mice and rats, the LD 50 for mice was generally > 3,600 mg/kg for oral administration and was > 2,300 mg/kg for intraperitoneal administration. In rats, the LD 50 was > 2,000 mg/kg for both oral and intraperitoneal administration.

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 the concomitant use of Miconazole and anticoagulants is envisaged, the anticoagulant effect should be carefully monitored and titrated. It is advisable to monitor Miconazole and phenytoin levels, if they are used concomitantly. Particularly in infants and young children, caution is required to ensure that the gel does not obstruct the throat. Hence, the gel should not be applied to the back of the throat and the full dose should be divided into smaller portions. Observe the patient for possible choking.

Compounds of similar chemical structure have produced various neurological disturbances such as dizziness, vertigo, uncoordination, and ataxia. If, during therapy with tinidazole, abnormal neurological signs develop, therapy should be discontinued. Use in Pregnancy & Lactation: Tinidazole is contraindicated during the first trimester of pregnancy. While there is no evidence that tinidazole is harmful during the late stages of pregnancy, its use during the last two trimesters requires that the potential benefits outweigh the possible risk to mother and foetus. Tinidazole is excreted in breast milk in concentrations similar to those seen in serum. Tinidazole can be detected in breast milk for up to 72 hours following administration. Interruption of breast-feeding is recommended during tinidazole therapy and for 3 days following the last dose.

Interaction

There have been reports of a heat reaction when this medication used concomitantly with Sofradex drops in the ear.

Antagonism with polyene antibiotics.

Miconazole can inhibit the metabolism of drugs metabolised by the Cytochrome P450-3A and -2C9 families. This can result in an increase or prolongation of their effects, including side effects. Miconazole Oral Gel should not be used during treatment with the following drugs: terfenadine, astemizole,mizolastine, cisapride, triazolam, oral midazolam, dofetilide, quinidine, pimozide, CYP3A4 metabolised HMG-CoA reductase inhibitors such as simvastatin and lovastatin.

The following interactions were reported with metronidazole, which is chemically-related to tinidazole.

Alcohol, disulfiram: Avoid during tinidazole use and for 3 days afterward because cramps, nausea, vomiting, headaches, and flushing may occur.

Anticoagulants, oral (eg, warfarin): Anticoagulant effects may be increased. Anticoagulant dose may need to be adjusted during coadministration and for up to 8 days after discontinuation.

Cholestyramine: Bioavailability of tinidazole may be decreased. Cyclosporine, lithium, tacrolimus: Levels may be elevated by tinidazole, increasing the risk of toxicity.

Drugs that induce CYP3A4 (eg, fosphenytoin, phenobarbital, phenytoin, rifampin): May increase metabolism of tinidazole, decreasing plasma levels and therapeutic effect.

Drugs that inhibit CYP3A4 (eg, cimetidine, ketoconazole): May prolong t½ and decrease tinidazole Cl, increasing plasma levels and risk of adverse reactions.

Fluorouracil: Cl may be decreased by tinidazole, increasing the risk of adverse reactions

Fosphenytoin, phenytoin: The t½ may be prolonged and Cl reduced by tinidazole, increasing the risk of adverse reactions.

Oxytetracycline: Therapeutic effect of tinidazole may be decreased.

Volume of Distribution

The topical form is minimally absorbed in the serum and tissues . Clotrimazole is a lipophilic drug , and has been shown to be secreted in breastmilk in animal studies . There are limited data available regarding the volume of distribution following oral troche administration.

A 1200 mg miconazole vaginal suppository resulted in a calculated apparent volume of distribution of 95 546 L while a 100 mg vaginal cream yielded an apparent volume of distribution of 10 911L.

• 50 L

Elimination Route

Because clotrimazole is generally not significantly absorbed, drug interactions are not a major issue with its use .

Miconazole given to healthy volunteers as a single 50 mg oral tablet produced a mean C_max of 15.1 ± 16.2 mcg/mL, a mean AUC_0-24 of 55.2 ± 35.1 mcg*h/mL, and a median T_max of 7 hours (range 2.0-24.1). In these patients measurable plasma concentrations ranged from 0.5 to 0.83 mcg/mL.

Topical miconazole is absorbed poorly into the systemic circulation. In pediatric patients aged 1-21 months given multiple topical applications of miconazole ointment for seven days, the plasma miconazole concentration was less than 0.5 ng/mL in 88% of the patients, with the remaining patients having a concentration of 0.57 and 0.58 ng/mL, respectively. Similarly, patients. administered with a vaginal 1200 mg ovule had a mean C_max of 10.71 ng/mL, mean T_max of 18.4 hours, and mean AUC_0-96 of 477.3 ng*h/mL.

Rapidly and completely absorbed under fasting conditions. Administration with food results in a delay in T_max of approximately 2 hours and a decline in C_max of approximately 10% and an AUC of 901.6 ± 126.5 mcg hr/mL.

Half Life

Miconazole has a terminal half-life of 24 hours.

The elimination half-life is 13.2±1.4 hours and the plasma half-life is 12 to 14 hours.

Elimination Route

Mainly hepatic .

Miconazole is excreted through both urine and feces; less than 1% of unchanged miconazole is recovered in urine.

Tinidazole crosses the placental barrier and is secreted in breast milk. Tinidazole is excreted by the liver and the kidneys. Tinidazole is excreted in the urine mainly as unchanged drug (approximately 20-25% of the administered dose). Approximately 12% of the drug is excreted in the feces.

Pregnancy & Breastfeeding use

Pregnancy:Clotrimazole is recommended during pregnancy only after first consulting a doctor.

Lactation:Because systemic absorption of clotrimazole following topical application is marginal, there should be no risk for the infant during lactation.

In animals, Miconazole has shown no teratogenic effects but is foetotoxic at high oral doses. The significance of this to man is unknown. However, as with other imidazoles, Miconazole Oral Gel should be avoided in pregnant women if possible. The potential hazards should be balanced against the possible benefits. It is not known whether Miconazole is excreted in human milk. Caution should be exercised when prescribing Miconazole Oral Gel to nursing mothers.

Only small amounts of Miconazole cream are absorbed following local administration. However as with other imidazoles, Miconazole nitrate should be used with caution during pregnancy.

Pregnancy Category C. Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.

Contraindication

Hypersensitivity to clotrimazole.

Miconazole is contraindicated in patients with known hypersensitivity to the active drug.

As with other compounds of similar structure, tinidazole, is contraindicated in patients having, or with a history of, blood dyscrasias although no persistent haematological abnormalities have been noted in clinical or animal studies. Tinidazole should be avoided in patients with organic neurological disorders. Tinidazole should not be administered to patients with known hypersensitivity to the compound.

Special Warning

Renal Impairment: Haemodialysis: Additional dose equal to half the usual dose at the end of haemodialysis.

Acute Overdose

Supportive measures should be taken incase of accidental oral ingestion.

In case of accidental oral ingestion, supportive measures should be taken.

In general, Miconazole is not highly toxic. In the event of accidental overdosage, vomiting and diarrhoea may occur.
