Mechanism of action
How Betamethasone + Phenylephrine + Lignocaine works — key points: • Betamethasone is a corticosteroid with mainly glucocorticoid activity. • It induces phospholipase A2 inhibitory lipase (lipocortins) and sequentially inhibits the release of arachidonic acid, thereby depressing the formation, release, and activity of prostaglandins, leukotrienes, and other inflammatory mediators. • Phenylephrine is a sympathomimetic with mainly direct effects on alpha-adrenergic receptors and weak beta-adrenergic activity. • It causes vasoconstriction of the arterioles of the nasal mucosa and conjunctiva; activates the dilator muscle of the pupil to cause contraction; produces vasoconstriction of arterioles in the body and produces systemic arterial vasoconstriction. • Lidocaine alters signal conduction in neurons by blocking the fast voltage-gated Na+ channels in the neuronal cell membrane responsible for signal propagation. • With sufficient blockage, the membrane of the postsynaptic neuron will not depolarize and will thus fail to transmit an action potential..
Dosage
Recommended schedule as per the manufacturer's literature: • A course of treatment should be limited to 7 days. Apply a small amount of ointment two or three times a day initially, using the applicator if internal administration is required. When inflammation is subsiding, once-daily application is sufficient in most cases. Or as directed by the physician.
