What is betamethasone lotion?
Betamethasone is a steroid and prevents the release of some substances in the body that cause inflammation. Betamethasone lotion (for skin) is used to treat inflammation and itching caused by diseases such as eczema, psoriasis, and allergic reactions.
What are the uses of betamethasone lotion?
Betamethasone is used for the symptomatic treatment of severe allergic or inflammatory skin disorders such as eczema that do not respond to other weaker corticosteroids, types of dermatitis, insect bites, and psoriasis.
Mechanism of action of betamethasone
This drug is connected to its specific receptors in the cytoplasm through the cell membrane, and the drug-receptor complex enters the cell nucleus. By binding to certain areas of DNA, this complex stimulates the process of mRNA transcription, followed by the production of inhibitory enzymes, which are believed to be responsible for anti-inflammatory inhibitory effects.
Pharmacokinetics of betamethasone
The metabolism of corticosteroids mainly takes place in the skin itself, but the skin metabolism of this drug is less than other topical corticosteroids. For this reason, its repeated prescription causes the accumulation of the drug in the skin and can lead to the prolongation of the effect, the aggravation of the side effects, and the increase in the systemic absorption of the drug. The drug also has liver metabolism.
