How Leclobe Plus 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.

Ofloxacin acts on DNA gyrase and toposiomerase IV, enzymes which, like human topoisomerase, prevents the excessive supercoiling of DNA during replication or transcription. By inhibiting their function, the drug thereby inhibits normal cell division.

Terbinafine inhibits the enzyme squalene monooxygenase (also called squalene epoxidase), preventing the conversion of squalene to 2,3-oxydosqualene, a step in the synthesis of ergosterol. This inhibition leads to decreased ergosterol, which would normally be incorporated into the cell wall, and accumulation of squalene.

Generation of a large number of squalene containing vesicles in the cytoplasm may leach other lipids away from, and further weaken, the cell wall.

Dosage

Leclobe Plus dosage

Apply by gently rubbing onto the affected area twice daily.

May be taken with or without food. Avoid antacids or supplements containing Fe or Zn within 2 hr before or after ofloxacin. Ensure adequate hydration.

Side Effects

Burning, itching, irritation, dry skin

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]

LD₅₀=5450 mg/kg (orally in mice)

The subcutaneous LD₅₀ in rats and mice is >2g/kg. The TDLO for women is 210mg/kg/6W.

Overdose data with terbinafine is rare, however symptoms are expected to be nausea, vomiting, abdominal pain, dizziness, rash, frequent urination, and headache. Treat overdose with activated charcoal as well as symptomatic and supportive therapy.

Precaution

Do not shallow. For external use only

Interaction

No hazardous interactions have been reported.

Volume of Distribution

Data regarding the volume of distribution of clobetasole propionate are not readily available.

A single 250mg oral dose of terbinafine has a volume of distribution at steady state of 947.5L or 16.6L/kg.

Elimination Route

Twice daily application of clobetasol foam leads to a C_max of 59±36pg/mL with a T_max of 5 hours. Clobetasol cream showed an increase in clobetasol concentrations from 50.7±96.0pg/mL to 56.3±104.7pg/mL.

Bioavailability of ofloxacin in the tablet formulation is approximately 98%

Oral terbinafine is >70% absorbed but only 40% bioavailable after first pass metabolism, reaching a C_max of 1µg/mL with a T_max of 2 hours an an AUC of 4.56µg*h/mL. Over the course of a week, 1% topical terbinafine's C_max increases from 949-1049ng/cm²

Half Life

Data regarding the half life of clobetasol propionate are not readily available.

9 hours

Oral terbinafine has an effective half life of approximately 36 hours. However, the terminal half life ranges from 200-400 hours as it distributes into skin and adipose tissue. 1% topical terbinafine's half life increases over the first seven days from approximately 10-40 hours.

Clearance

Data regarding the clearance of clobetasol propionate are not readily available.

A single 250mg oral dose of terbinafine has a clearance of 76L/h or 1.11L/h/kg.

Elimination Route

Corticosteroids are eliminated predominantly in the urine.

Ofloxacin is mainly eliminated by renal excretion, where between 65% and 80% of an administered oral dose of ofloxacin is excreted unchanged via urine within 48 hours of dosing. About 4-8% of an ofloxacin dose is excreted in the feces and the drug is minimally subject to biliary excretion.

Terbinafine is approximately 80% eliminated in urine, while the remainder is eliminated in feces. The unmetabolized parent drug is not present in urine.

Pregnancy & Breastfeeding use

The safe use of Leclobe Plus during pregnancy & lactation has not been established.

Contraindication

Contraindicated in patients hypersensitive to any of the components of the formulation.

Special Warning

Use in Paediatrics: The drug may be used in paediatrics patients in appropriate dosage, but large quantities for prolonged period should be avoided. It is contraindicated in children less than one year.

Renal Impairment:

• CrCl <20 and patients on haemodialysis or peritoneal dialysis: 100 mg 24 hrly following usual initial dose.
• CrCl 20-50: Reduce dose by half 24 hrly following usual initial dose.

Hepatic Impairment:Severe: Reduce dose. Max: 400 mg daily

Use in Children: Terbinafine cream appears to be an effective and well-tolerated treatmenr of tinea corposis and tinea cruris in children.

Use in Elderly: Terbinafine appears to be safe in the elderly. The dose should be reduced by half if significant hepatic or renal impairment is present.

Acute Overdose

Acute overdosage is very unlikely to occur. However, in the case of chronic overdose or misuse the features of hypercortisolism may appear.

Symptoms: Confusion, dizziness, impairment of consciousness, convulsive seizures, GI reactions (e.g. nausea, mucosal erosions).

Management: Symptomatic and supportive treatment. Remove any unabsorbed drug by gastric lavage or admin of adsorbants and Na sulfate. Antacids are recommended for protection of gastric mucosa. Elimination may be increased by forced diuresis.

Renal Impairment Haemodialysis patients: Give a supplemental dose (50% of the usual dose) before dialysis.

Hepatic Impairment Severe: Double the interval between doses.

Clinical experience regarding overdose with terbinafine tablets is limited. Doses up to 5 grams (20 times the therapeutic daily dose) have been taken without inducing serious adverse reactions. The symptoms of overdose included nausea, vomiting, abdominal pain, dizziness, rash, frequent urination, and headache.

Storage Condition

Store below 30°c. keep away from light and out of the reach of children. Do not freeze.
