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 .

Povidone-iodine is an iodophore with a powerful broad-spectrum germicidal activity against a wide range of bacteria, viruses, fungi, protozoa and spores. Microbicidal; oxidizes cell constituents; iodinates proteins and inactivates them.

Povidone iodine is a kind of iodine disinfectant which directly cause in vivo protein denaturation, precipitation of bacteria, and further resulting in the death of pathogenic microorganisms. Therefore, it is effective in disinfection and sterilization. It can kill viruses, bacteria, spores, fungi, and protozoa with low toxicity to human. Povidone-iodine aqueous solution has strong pharmacological activity against Staphylococcus aureus, Neisseria gonorrhoeae, Pseudomonas aeruginosa, syphilis, hepatitis B virus, HIV, and Trichomonas vaginalis.Povidone iodine gel is a gynecological topical semi-mobile colloidal agent made by povidone iodine and hydrophilic matrix. It is a system for maintaining its sustained release. Owing to the continuous release of free iodine, it can enable the skin and mucous membranes to maintain a certain effective concentration of iodine for killing bacteria. It is mainly used for gynecological vaginal infection. It exerted its effect through being miscible with vaginal secretions and further killing the inside pathogenic microorganisms, and thus blocking the spread of sexually transmitted diseases and invasion, as well as treating other infected vaginal diseases caused by other kinds of bacteria.

Published reports on the in vitro antimicrobial efficacy of iodophors demonstrate that iodophors are bactericidal, mycobactericidal, and virucidal but can require prolonged contact times to kill certain fungi and bacterial spores. Three brands of povidone-iodine solution have demonstrated more rapid kill (seconds to minutes) of S. aureus and M. chelonae at a 1:100 dilution than did the stock solution. The virucidal activity of 75–150 ppm available iodine was demonstrated against seven viruses. Other investigators have questioned the efficacy of iodophors against poliovirus in the presence of organic matter and rotavirus in distilled or tapwater. Manufacturers' data demonstrate that commercial iodophors are not sporicidal, but they are tuberculocidal, fungicidal, virucidal, and bactericidal at their recommended use-dilution.

Tinidazole, a 5-nitroimidazole derivative with antimicrobial actions similar to metronidazole, is active against both protozoa (e.g. Trichomonas vaginalis, Entamoeba histolytica and Giardia lamblia) and obligate anaerobic bacteria. It damages DNA strands or inhibits DNA synthesis in microorganism.

Tinidazole is a synthetic antiprotozoal agent. Tinidazole demonstrates activity both in vitro and in clinical infections against the following protozoa: Trichomonas vaginalis, Giardia duodenalis (also termed G. lamblia), and Entamoeba histolytica. Tinidazole does not appear to have activity against most strains of vaginal lactobacilli.

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 Dresin V Vaginal 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 .

Povidone-iodine is called iodophore which means povidone acts as a carrier of iodine. Iodine is considered as the active moiety that mediates microbicidal actions. When released from the complex, free iodine (I2) penetrates the cell wall of microorganisms quickly, and the lethal effects are believed to result from disruption of protein and nucleic acid structure and synthesis. While the full mechanism of action is not fully elucidated, iodine is thought to inhibit vital bacterial cellular mechanisms and structures, and oxidizes nucleotides fatty or amino acids in bacterial cell membranes . Additionally, free iodine disrupts the function of the cytosolic enzymes involved in the respiratory chain, causing them to become denatured and deactivated . In vitro evidence suggests that iodine also counteracts inflammation elicited by both pathogens and the host response via multifactorial effects. In hosts, povidone-iodine was demonstrated to modulate the redox potential, inhibit the release of inflammatory mediators such as TNF-α and β-galactosidase, inhibit metalloproteinase production, and potentiate the healing signals from pro-inflammatory cytokines by activation of monocytes, T-lymphocytes, and macrophages, in vitro .

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.

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.

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.

Local skin irritation and sensitivity. Application to large areas of denuded skin may produce systemic effects due to iodine absorption.The application of povidone iodine to large wounds or severe burns may producesystemic adverse effectssuch as metabolic acidosis, hypernatraemia and impairment of renal function.

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 .

ORAL (LD50): Acute: 8000 mg/kg [Rat]. 8100 mg/kg [Mouse]

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.

Avoid contact with eyes; should not be used under occlusive dressing. Pregnancy, lactation

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.

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.

Povidone-Iodine is intended for topical application and has no volume of distribution.

50 L

Elimination Route

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

Povidone-Iodine is intended for topical application and is not absorbed.

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

Povidone-Iodine is intended for topical application and is not eliminated.

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

Clearance

Povidone-Iodine is intended for topical application and is not eliminated.

Elimination Route

Mainly hepatic .

Povidone-Iodine is intended for topical application and is not eliminated.

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.

Pregnancy Category D. There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

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.

Hypersensitivity; prolonged use in patients with thyroid disorders or on lithium therapy. Special caution is needed when regular applications to broken skin are made to patients with pre-existing renal insufficiency. Regular use should be avoided in patients on concurrent lithium therapy.

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.
