Terminal elimination half-life is approximately 20-50 hours. Dose adjustments not required in renal impairment, but caution in hepatic impairment.
Terminal elimination half-life approximately 24 hours (range 20–28 h), supports once-daily dosing; prolonged in severe hepatic impairment.
Hepatic metabolism via CYP3A4 and CYP2C9; excreted in feces and urine as metabolites.
Primarily metabolized by CYP3A4
Approximately 70% of absorbed dose is excreted in feces as unchanged drug and metabolites; about 20% is excreted renally as metabolites with less than 1% unchanged. Biliary excretion is a minor route.
Primarily hepatic metabolism with biliary excretion; ~20% renal elimination of unchanged drug. Fecal excretion of metabolites accounts for ~65% of total clearance.
Approximately 98% bound to plasma proteins, primarily albumin and alpha-1-acid glycoprotein.
High protein binding, approximately 99.8%, primarily to albumin and alpha-1-acid glycoprotein.
Volume of distribution is approximately 2.5-4.0 L/kg, indicating extensive tissue distribution.
Volume of distribution ~0.15 L/kg (range 0.12–0.18 L/kg), indicating limited extravascular distribution, predominantly confined to plasma and extracellular fluid.
Topical: minimal systemic absorption (<0.5%). Oral: not available; vaginal: approximately 3-10% systemic absorption.
Oral bioavailability ~85%; unaffected by food.
No dose adjustment required for topical or vaginal use. For troches, no data available; however, systemic absorption is minimal.
GFR ≥60 m L/min: no adjustment; GFR 30-59 m L/min: 200 mg twice daily; GFR <30 m L/min: 200 mg once daily; hemodialysis: 200 mg three times weekly after dialysis.
No dose adjustment required for topical or vaginal use. For troches, use with caution in severe hepatic impairment due to limited data.
Child-Pugh A: no adjustment; Child-Pugh B: 200 mg twice daily; Child-Pugh C: 200 mg once daily.
Topical: Apply to affected area twice daily for 2-4 weeks (safe for all ages). Vaginal: Not recommended in prepubertal children. Troches: Not recommended for children under 5 years due to risk of choking; for children ≥5 years, same dose as adults (10 mg troche five times daily).
Body weight 10-20 kg: 200 mg twice daily; 20-40 kg: 300 mg twice daily; ≥40 kg: 400 mg twice daily.
No specific dose adjustment required. Use same dosing as adults. Consider skin fragility with topical application.
No specific dose adjustment based on age alone; monitor renal function and adjust per renal guidelines.
None
No FDA black box warning.
For external use only; avoid contact with eyes; discontinue if hypersensitivity occurs; not for ophthalmic or oral use; use in pregnancy only if clearly needed (Category B).

Hypersensitivity to clotrimazole or any component of the formulation
Hypersensitivity to everolimus or any component of the formulation
No known significant food interactions.
Avoid grapefruit and grapefruit juice; may increase drug levels. Take with or without food, but high-fat meals may increase absorption. Avoid alcohol due to hepatotoxicity risk.
Clotrimazole (LOTRIMIN) topical use is not associated with increased risk of major congenital malformations. Systemic absorption is minimal (<0.5% after vaginal or topical application). First trimester vaginal use has insufficient data, but no clear teratogenic signal. Second and third trimester vaginal use is considered safe. Overall, risk is low due to negligible systemic exposure.
First trimester: Avoid use due to potential for fetal harm based on animal studies showing developmental toxicity (including cardiovascular and skeletal malformations). Second and third trimesters: Use only if maternal benefit outweighs fetal risk; may cause fetal growth restriction or oligohydramnios in off-label experience. No adequate human data.
Minimal systemic absorption after topical or vaginal use leads to negligible excretion into breast milk. M/P ratio is not applicable due to undetectable levels. Suitable for use during breastfeeding. No adverse effects reported in nursing infants.
No human data on milk excretion or infant effects. M/P ratio unknown. Due to potential for serious adverse reactions (e.g., immunosuppression), advise against breastfeeding during treatment and for 2 weeks after last dose.
No dose adjustment required during pregnancy. Pharmacokinetics of topical/vaginal clotrimazole are unchanged due to minimal systemic absorption. Standard dosing (e.g., 100 mg vaginal tablet for 7 days or 500 mg single dose) is appropriate.
No established dose adjustment in pregnancy. Consider reduced dosing if increased clearance occurs (second trimester). Monitor drug levels if available; otherwise, adjust based on clinical response and toxicity.
Clotrimazole is a broad-spectrum antifungal agent; Topical formulations (cream, solution, lotion) are preferred for dermatophytosis; Vaginal tablets must be inserted high into the vagina; Avoid use on broken or inflamed skin; Monitor for local irritation.
Monitor for QT prolongation, electrolyte abnormalities, and hepatotoxicity. Adjust dose in renal impairment (Cr Cl <30 m L/min). Avoid use with strong CYP3A4 inhibitors or inducers. Note potential for phototoxicity; advise sun avoidance.
Apply the medication to the affected area as directed, usually twice daily.,Wash hands before and after application unless treating hands.,For vaginal tablets, insert one tablet deep into the vagina at bedtime for 3 or 7 days.,Complete the full course even if symptoms improve.,Avoid tight-fitting clothing and synthetic fabrics; keep area clean and dry.
Take exactly as prescribed; do not change dose or stop without consulting doctor.,Avoid grapefruit and grapefruit juice during treatment.,Use effective contraception during therapy and for 1 month after last dose.,Report symptoms like irregular heartbeat, fainting, severe nausea/vomiting, or yellowing of skin/eyes immediately.,Use sunscreen and protective clothing; avoid sun exposure, even through glass.

Common clinical questions about LOTRIMIN vs AUKELSO, answered by our medical review team.
LOTRIMIN is a Topical Antifungal that works by Clotrimazole inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.. AUKELSO is a Topical Antifungal that works by Selective inhibitor of the mammalian target of rapamycin (m TOR) kinase, specifically the m TORC1 complex, leading to inhibition of cell proliferation, angiogenesis, and glucose uptake.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between LOTRIMIN and AUKELSO depend on the specific clinical indication. These are both Topical Antifungal agents and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of LOTRIMIN is: Clotrimazole 1% cream or solution applied topically to affected area twice daily for 2-4 weeks. For vaginal tablets: 100 mg intravaginally once daily for 7 days or 500 mg single dose. For troches: 10 mg troche dissolved slowly in mouth five times daily for 14 days.. The standard adult dose of AUKELSO is: 400 mg orally twice daily with food.. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between LOTRIMIN and AUKELSO in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
The maternal-fetal safety profiles differ. LOTRIMIN is classified as Category C. Clotrimazole (LOTRIMIN) topical use is not associated with increased risk of major congenital malformations. Systemic absorption is minimal (<0.5% after vaginal or topical applicat. AUKELSO is classified as Category C. First trimester: Avoid use due to potential for fetal harm based on animal studies showing developmental toxicity (including cardiovascular and skeletal malformations). Second and . Always consult a maternal-fetal medicine specialist before taking either drug during pregnancy or lactation.
