Dermifree Tube Uses, Dosage, Side Effects, Food Interaction and all others data.
Clobetasol Propionate Cream is a multiple combination cream which exhibits anti-bacterial, anti-protozoal, anti-fungal and steroid properties to control inflammation. Ofloxacin is a broad-spectrum antibiotic that acts against many gram-positive and gram-negative bacteria. Ornidazole belongs
to the nitroimidazole group of antibiotics and is used to treat amoeba and trichomonas infections. Terbinafine is a topical antifungal and antiparasitic drug. Clobetasol is a potent corticosteroid which exhibits anti-inflammatory, anti-pruritic and vasoconstrictive properties.
Corticosteroids bind to the glucocorticoid receptor, inhibiting pro-inflammatory signals, and promoting anti-inflammatory signals. Clobetasol propionate is generally applied twice daily so the duration of action is long. Corticosteroids have a wide therapeutic window as patients may require doses that are multiples of what the body naturally produces. Patients taking corticosteroids should be counselled regarding the risk of hypothalamic-pituitary-adrenal axis suppression and increased susceptibility to infections.
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 .
Gentamicin sulphate actively transported across the bacterial cell membrane, binds to a specific receptor protein on the 30S subunit of bacterial ribosomes and interferes with an initiation complex between mRNA (messenger RNA) and the 30 S subunit, inhibiting protein synthesis. DNA may be misread, thus producing nonfunctional proteins; polyribosomes are split apart and are unable to synthesize protein.
Eye drops may be absorbed following topical application to the eye. Ear drops may be absorbed following topical application to the ear, especially if the eardrum is perforated or if tissue damage is present.
Gentamicin sulphate is active against many strains of the following microorganisms: Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, Haemophilus influenzae, Klebsiella pneumoniae, Niesseria gonorrhoea, Pseudomonus aeruginosa, and Serratia marcescens.
Tolnaftate is an antifungal which inhibits growth of dermatophytes e.g. Epidermophyton, Microsporum, trichophyton spp, and Malassezia furfur by distorting the hyphae and stopping mycelial growth. It is inactive against Candida spp or bacteria.
Tolnaftate is a synthetic over-the-counter anti-fungal agent.

How Dermifree Tube works
The short term effects of corticosteroids are decreased vasodilation and permeability of capillaries, as well as decreased leukocyte migration to sites of inflammation. Corticosteroids binding to the glucocorticoid receptor mediates changes in gene expression that lead to multiple downstream effects over hours to days.
Glucocorticoids inhibit neutrophil apoptosis and demargination; they inhibit phospholipase A2, which decreases the formation of arachidonic acid derivatives; they inhibit NF-Kappa B and other inflammatory transcription factors; they promote anti-inflammatory genes like interleukin-10.
Lower doses of corticosteroids provide an anti-inflammatory effect, while higher doses are immunosuppressive. High doses of glucocorticoids for an extended period bind to the mineralocorticoid receptor, raising sodium levels and decreasing potassium levels.
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 .
There are 3 key phases of aminoglycoside entry into cells. The first “ionic binding phase” occurs when polycationic aminoglycosides bind electrostatically to negatively charged components of bacterial cell membranes including with lipopolysaccharides and phospholipids within the outer membrane of Gram-negative bacteria and to teichoic acids and phospholipids within the cell membrane of Gram-positive bacteria. This binding results in displacement of divalent cations and increased membrane permeability, allowing for aminoglycoside entry. The second “energy-dependent phase I” of aminoglycoside entry into the cytoplasm relies on the proton-motive force and allows a limited amount of aminoglycoside access to its primary intracellular target - the bacterial 30S ribosome. This ultimately results in the mistranslation of proteins and disruption of the cytoplasmic membrane.[A233320] Finally, in the “energy-dependent phase II” stage, concentration-dependent bacterial killing is observed. Aminoglycoside rapidly accumulates in the cell due to the damaged cytoplasmic membrane, and protein mistranslation and synthesis inhibition is amplified. The necessity of oxygen-dependent active transport explains why aminoglycosides are ineffective against anaerobic bacteria. Hence, aminoglycosides have both immediate bactericidal effects through membrane disruption and delayed bactericidal effects through impaired protein synthesis; observed experimental data and mathematical modeling support this two-mechanism model. Inhibition of protein synthesis is a key component of aminoglycoside efficacy. Structural and cell biological studies suggest that aminoglycosides bind to the 16S rRNA in helix 44 (h44), near the A site of the 30S ribosomal subunit, altering interactions between h44 and h45. This binding also displaces two important residues, A1492 and A1493, from h44, mimicking normal conformational changes that occur with successful codon-anticodon pairing in the A site.[A232324, A232329] Overall, aminoglycoside binding has several negative effects including inhibition of translation, initiation, elongation, and ribosome recycling. Recent evidence suggests that the latter effect is due to a cryptic second binding site situated in h69 of the 23S rRNA of the 50S ribosomal subunit.[A232329, A232339] Also, by stabilizing a conformation that mimics correct codon-anticodon pairing, aminoglycosides promote error-prone translation.[A232344] Mistranslated proteins can incorporate into the cell membrane, inducing the damage discussed above.
Tolnaftate is a topical fungicide. Though its exact mechanism unknown, it is believed to prevent ergosterol biosynthesis by inhibiting squalene epoxidase. It has also been reported to distort the hyphae and to stunt mycelial growth in susceptible organisms.

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.
Eye: 1-2 drops instilled in affected eye up to 6 times a day or more frequently if required (severe infections may require 1-2 drops every 15-20 minutes initially, reducing the frequency of instillation gradually as the infection is controlled).
Ear: The area should be cleaned and 2-3 drops should be instilled every 3-4 times a day and at night, or more frequently if required.
A small amount of Gentamicin should be applied gently to the affected areas three to four times daily. The area treated may be covered with a gauze dressing if desired. Before applying the medication the affected area should be properly cleaned.
Use this medication on the skin only. Clean and thoroughly dry the area to be treated. Apply this medication to the affected skin, usually twice a day or as directed on the product package or by your doctor. Dosage and length of treatment depends on the type of infection being treated.
Some forms of tolnaftate (e.g., powder) need to be shaken before applying. Check your product package to see if your form of this medication needs to be shaken. Apply enough medication to cover the affected area and some of the surrounding skin. After applying this medication, wash your hands. Do not wrap, cover, or bandage the area unless directed to do so by your doctor.
Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time(s) each day.
Continue to use this medication until the full prescribed amount is finished, even if symptoms disappear after starting tolnaftate. Stopping the medication too early may allow the fungus to continue to grow, which may result in a relapse of the infection.
Inform your doctor if your condition persists after 2 weeks of treatment for jock itch, after 4 weeks of treatment for athlete's foot or ringworm, or if your condition worsens at any 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.
Side Effects
Generally Clobetasol Propionate is well tolerated. However, few side effects after prolonged and intensive treatment may cause local atrophic changes in the skin such as Burning, itching, irritation, dry skin eczema.
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.
In patients with dermatoses treated with gentamicin, irritation (erythema and pruritus) had been reported in small number of cases. Itching, redness, swelling or other signs of irritation may develop. With the eye/ear drop bacterial and corneal ulcer have developed during treatment with gentamicin. Most frequently reported adverse reactions are ocular burning and irritation upon drug instillation, non specific conjunctivitis, conjunctival epithelial defects, and conjunctival hyperemia.
Gentamicin cream is well tolerated. There has been no evidence of irritation and sensitization after using Gentamicin cream.
Irritation of the treated skin may occur. If this effect persists or worsens, notify your doctor or pharmacist promptly.
If your doctor has directed you to use this medication, remember that he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
Toxicity
Data regarding acute overdoses of glucocorticoids are rare. Overdoses of clobetasol propionate can lead to reversible HPA axis suppression and glucocorticoid insufficiency. Chronic high doses of glucocorticoids can lead to the development of cataract, glaucoma, hypertension, water retention, hyperlipidemia, peptic ulcer, pancreatitis, myopathy, osteoporosis, mood changes, psychosis, dermal atrophy, allergy, acne, hypertrichosis, immune suppression, decreased resistance to infection, moon face, hyperglycemia, hypocalcemia, hypophosphatemia, metabolic acidosis, growth suppression, and secondary adrenal insufficiency.[A188405] Overdose may be treated by adjusting the dose or stopping the corticosteroid as well as initiating symptomatic and supportive treatment.[A188405]
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 .
As with other aminoglycosides, nephrotoxicity and ototoxicity are associated with gentamicin. Signs of nephrotoxicity include an increase in plasma creatinine and urea, while signs of ototoxicity include issues with balance, nausea, tinnitus, and hearing loss. It is important to note that aminoglycoside-induced nephrotoxicity is typically reversible, while ototoxicity is more likely to be permanent. The risk of both toxicities increases with long-term gentamicin therapy. Gentamicin is considered to be more vestibulotoxic than cochleotoxic compared to other aminoglycosides. Unfortunately, gentamicin-related ototoxicity does not correlate with cumulative dosing, peak and trough levels, or dosing schedule. The unpredictability of ototoxicity supports close monitoring of the patient throughout treatment. In cases of toxicity or overdose, the medication should be discontinued immediately; hemodialysis may be initiated to lower gentamicin serum concentrations.
Oral rat LD50: 891 mg/kg. Inhalation rat LC50: > 900 mg/m3/1hr. Irritation: skin rabbit: 500 mg/24H mild. Eye rabbit: 100 mg severe. Investigated a mutagen and reproductive effector.
Precaution
Do not swallow. For external use only.
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 these occurs or if irritation, sensitization develops, treatment with gentamicin should be discontinued and appropriate therapy instituted. Gentamicin ear/eye drops is not for injection. It should never be injected subconjunctivally, nor it should be directly introduced into the anterior chamber of the eye.
Use of topical antibiotics occasionally cause overgrowth of nonsusceptible organisms including fungi. If this occurs or if irritation, sensitisation or super infection develops, treatment with Gentamicin should be discontinued and appropriate therapy should be instituted.
Before using tolnaftate, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: immune system problems (e.g., organ transplant, HIV disease), diabetes.

Interaction
No hazardous interactions have been reported with use of Clobetasol Propionate.
There have been reports of a heat reaction when this medication used concomitantly with Sofradex drops in the ear.
Antagonism with polyene antibiotics.
None has been reported so far with topical and Eye/Ear drops.
There are no known significant interactions.
Volume of Distribution
Data regarding the volume of distribution of clobetasole propionate are not readily available.
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.
Elimination Route
Twice daily application of clobetasol foam leads to a Cmax of 59±36pg/mL with a Tmax of 5 hours. Clobetasol cream showed an increase in clobetasol concentrations from 50.7±96.0pg/mL to 56.3±104.7pg/mL.
Because clotrimazole is generally not significantly absorbed, drug interactions are not a major issue with its use .
Half Life
Data regarding the half life of clobetasol propionate are not readily available.
One study assessing the pharmacokinetics of gentamicin in children and adults reported a mean half-life of 75 minutes after intravenous administration. The mean half-life associated with intramuscular administration was about 29 minutes longer. Fever and anemia may result in a shorter half-life although dose adjustments are not usually necessary. Severe burns are also associated with a shorter half-life and may result in lower gentamicin serum concentrations.
Clearance
Data regarding the clearance of clobetasol propionate are not readily available.
The renal clearance of gentamicin is comparable to individual creatinine clearance.
Elimination Route
Corticosteroids are eliminated predominantly in the urine.
Mainly hepatic .
Gentamicin is excreted primarily by the kidneys. In patients with normal renal function, 70% or more of an initial gentamicin dose can be recovered in the urine within 24 hours. Excretion of gentamicin is significantly reduced in patients with renal impairment.
Pregnancy & Breastfeeding use
The safe use of Clobetasol Propionate during pregnancy & lactation has not been established.
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.
Consideration should be given the possibility of foetal ototoxicity when gentamicin is applied topically to large denuded areas of skin. For Gentamicin Eye/Ear Drops safety profile in pregnancy is not yet established and should be administered when considered essential.
Tolnaftate topical has not been formally assigned to a pregnancy category by the FDA. Animal studies have not been reported. There are no controlled data in human pregnancy.
