🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines a local anaesthetic and a corticosteroid. Lidocaine blocks sodium channels in nerve endings, preventing the generation and conduction of pain signals, which results in rapid numbness. Betamethasone binds to glucocorticoid receptors inside cells, leading to suppression of inflammatory mediators such as prostaglandins and leukotrienes, and reduces swelling, redness, and itching. Together, they provide both immediate pain relief and sustained anti-inflammatory action.
