Topical: minimal systemic absorption (<0.5%). Oral: not available; vaginal: approximately 3-10% systemic absorption.
Oral: 99% (well absorbed); food does not affect absorption. No IV formulation due to poor water solubility; not administered topically for systemic effects.
No dose adjustment required for topical or vaginal use. For troches, no data available; however, systemic absorption is minimal.
Cr Cl 30-60 m L/min: 100 mg once daily; Cr Cl 15-29 m L/min: 50 mg once daily; Cr Cl <15 m L/min: 50 mg every 48 hours
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: 100 mg once daily; Child-Pugh C: not recommended
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).
Not established for children <18 years of age
No specific dose adjustment required. Use same dosing as adults. Consider skin fragility with topical application.
No specific adjustment required; consider renal function and potential for increased sensitivity
None
Fetal toxicity: Drugs acting directly on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected.
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).

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.
Teratogenic risk profile for Candesartan (CANDEX) is based on its mechanism as an angiotensin II receptor blocker (ARB). First trimester: No increased risk of major congenital malformations from first-trimester exposure based on human data, but animal studies show fetal toxicity at high doses. Second and third trimesters: Known to cause fetal renal dysfunction, oligohydramnios, skull ossification defects, and neonatal renal failure. Use is contraindicated in pregnancy, especially after 20 weeks gestation.
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.
Excretion into breast milk is unknown; limited data may be available for similar ARBs but M/P ratio is not established. Due to risk of neonatal renal effects, use during breastfeeding is not recommended, especially in preterm infants or those with renal impairment. Alternative agents preferred.
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.
Pharmacokinetic changes in pregnancy (increased volume of distribution, renal blood flow) may require dose adjustments. However, due to fetotoxicity, candesartan is contraindicated in pregnancy, and no dose recommendation is provided. Alternative antihypertensives such as labetalol or nifedipine are preferred.
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.
Candesartan is contraindicated in pregnancy (category D). Monitor renal function and electrolytes, especially in renal artery stenosis, heart failure, or volume depletion. May cause hypotension, especially in CHF patients. Dual blockade with ACEi increases risk of hyperkalemia and renal impairment.
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, usually once daily.,Avoid potassium supplements or salt substitutes containing potassium without medical advice.,If you become pregnant, stop taking and contact your doctor immediately.,May cause dizziness or lightheadedness; avoid driving until you know how you react.,Report any signs of angioedema (swelling of face, lips, throat) or fainting.,Stay hydrated, especially if experiencing diarrhea or vomiting.
