Pharmacology and Mechanism of Action
Anti - Inflammatory Effect
Betamethasone dipropionate is a potent corticosteroid. It exerts its anti - inflammatory action by inhibiting the release of inflammatory mediators, such as prostaglandins, leukotrienes, and cytokines. This helps to reduce the redness, swelling, and pain associated with inflammation.
Immunosuppressive Effect
It suppresses the immune system by inhibiting the activity of immune cells like lymphocytes, macrophages, and eosinophils. This is beneficial in treating immune - mediated and allergic disorders.
Dosage and Administration
It is typically available as a cream, ointment, or lotion for topical use. The affected area is usually cleaned and dried before applying a thin layer of the medication. The frequency of application depends on the severity of the condition, but it is often applied once or twice daily.
