Answer

Anesthetics, Topical

These agents stabilize the neuronal membrane so the neuron is less permeable to ions. This prevents the initiation and transmission of nerve impulses, thereby producing the local anesthetic action.

Lidocaine transdermal (Lidoderm, Ztlido)

Lidocaine transdermal is indicated for pain associated with postherpetic neuralgia. Lidoderm 5% transdermal patch contains 700 mg of lidocaine per patch. ZTlido 1.8% transdermal patch contains 36 mg per patch. Pharmacokinetic studies have demonstrated bioequivalence of the 2 patches. The ZTlido 1.8% patch is engineered to provide improved adhesion and flexibility to provide targeted transdermal absorption, so a lower amount of lidocaine can be used.
