anesthetic lidocaine powder, is a very good local anesthetic, anesthetic lidocaine powder generally taking effect one to three minutes after application and lasting one to three hours. Used to treat mouth ulcers. It is no longer used very often as a heart rhythm drug due to concerns about its long-term side effects
The local anesthetic lidocaine powder, potency and duration of lidocaine are stronger than that of procaine, but the toxicity is also greater. The deethyl metabolite (monoethylglycinamide xylene) metabolized in the liver still has local anesthetic properties, but its toxicity is increased. It is further degraded by amidase and excreted in urine, and 10% of the dosage is excreted in its original form.
