TEMOVATE
Clinical safety rating: caution
Comprehensive clinical and safety monograph for TEMOVATE (TEMOVATE).
Corticosteroid that binds to glucocorticoid receptors, modulating gene transcription to inhibit inflammatory mediators (prostaglandins, leukotrienes) and suppress immune response.
| Metabolism | Primarily hepatic via CYP3A4; metabolites are excreted in urine and feces. |
| Excretion | Primarily renal; less than 10% as unchanged drug, majority as metabolites. Fecal elimination is minimal (<5%). |
| Half-life | Terminal half-life approximately 36-54 hours, with clinical context indicating prolonged skin retention due to high lipophilicity and slow release from stratum corneum. |
| Protein binding | Extensive (>99%) binding to plasma proteins, including albumin and corticosteroid-binding globulin. |
| Volume of Distribution | Volume of distribution not well characterized for topical administration due to limited systemic absorption; for iv data, Vd approximately 0.5-1 L/kg, indicating distribution into total body water and some tissue binding. |
| Bioavailability | Topical: Systemic bioavailability varies widely (1-5% in intact skin, up to 30-50% in inflamed or occluded skin). |
| Onset of Action | Topical: within 24-48 hours for reduction of inflammation and pruritus. |
| Duration of Action | Duration of action after single topical application lasts 1-2 weeks, but clinical improvement often requires daily application for 2-4 weeks; note that prolonged use may lead to tachyphylaxis. |
Apply a thin layer to affected skin areas twice daily (morning and evening). Maximum duration of treatment is 2 consecutive weeks. Do not use more than 50 g per week.
| Dosage form | SOLUTION |
| Renal impairment | No data available; no specific dose adjustment recommendations for renal impairment. |
| Liver impairment | No data available; caution advised in severe hepatic impairment due to potential for increased systemic absorption. |
| Pediatric use | Safety and efficacy not established in pediatric patients below 12 years of age. For children 12 years and older, same adult dosing applies with caution (maximum 2 weeks, limited to small areas). |
| Geriatric use | Use with caution; apply sparingly to smallest affected area for shortest duration due to increased skin atrophy risk. |
| 1st trimester | Consult provider |
| 2nd trimester | Consult provider |
| 3rd trimester | Consult provider |
Clinical note
Comprehensive clinical and safety monograph for TEMOVATE (TEMOVATE).
| Breastfeeding | Systemic absorption is low after topical application, but avoid application to breast area. No M/P ratio available. Use with caution; monitor infant for signs of HPA suppression (e.g., poor weight gain, growth retardation). |
| Teratogenic Risk | Insufficient human data; animal studies show cleft palate and fetal growth retardation at topical doses. Risk cannot be excluded; use only if benefit outweighs risk. First trimester: avoid if possible. Second/third trimesters: avoid prolonged use on large areas or occluded skin due to potential fetal HPA suppression. |
■ FDA Black Box Warning
None.
| Serious Effects |
["Hypersensitivity to clobetasol propionate or any component","Untreated bacterial, fungal, viral, or parasitic skin infections","Prolonged use in children (risk of growth suppression)"]
| Precautions | ["Reversible HPA axis suppression with prolonged use or large surface area","Cushing's syndrome from systemic absorption","Local adverse reactions: skin atrophy, striae, telangiectasias, acneiform eruptions","Prolonged use may increase risk of secondary infections","Avoid use on face, groin, axillae, or under occlusive dressings unless directed"] |

| Fetal Monitoring |
| Monitor maternal skin atrophy and HPA axis suppression (ACTH stimulation test recommended if used >2 weeks on large areas). In fetus: monitor fetal growth via ultrasound if prolonged use. |
| Fertility Effects | No human data; animal studies show no impact on fertility. Theoretical risk of hypothalamic-pituitary-adrenal axis suppression with high-dose exposure. |
