Betamethasone 17-valerate Biological Activity

Description	Betamethasone valerate (Betamethasone 17-valerate), the 17-valerate ester of Betamethasone, is a topical corticosteroid with anti-inflammatory activity. Betamethasone valerate is used in the treatment of recurrent aphthous stomatitis. Betamethasone valerate inhibits the binding of the radiolabeled glucocorticoid dexamethasone (3H dexamethasone) to human epidermis and mouse skin with IC50s of 5 and 6 nM, respectively[1][2][3].

In Vivo	Betamethasone valerate (10 mg; 5 minutes; applied to the irritated site with a micro spatula) ointment inhibits about 50% of the ear edema without thymus atrophy[4]. Betamethasone-17-valerate ointment (50 mg) inhibits homologous passive cutaneous anaphylaxis[4]. Animal Model: Female Sprague-Dawley rats weighing 60-70 g (croton oil edema experiment)[4] Dosage: 10 mg Administration: Applied to the irritated site with a micro spatula; 5 minutes Result: Inhibited about 50% of the ear edema without thymus atrophy.

Section 4. First Aid Measures
Eye ContactCheck for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at
least 15 minutes. Cold water may be used. WARM water MUST be used. Get medical attention if irritation
occurs.
Skin ContactIn case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated
clothing and shoes. Cover the irritated skin with an emollient. Wash clothing before reuse. Thoroughly clean
shoes before reuse. Get medical attention.
Serious Skin ContactWash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical
attention.
InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get
medical attention.
Serious InhalationNot available.

respiratory equipment. If ingested, seek medical advice immediately and show the container or the label.
StorageKeep container tightly closed. Keep container in a cool, well-ventilated area.

Section 8. Exposure Controls/Personal Protection
Engineering ControlsUse process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal ProtectionSafety glasses. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves.
Personal Protection in Case of Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
a Large Spillto avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist
BEFORE handling this product.
