Background Therapy with local anesthetics (LAs) also known as neural therapy is used in integrative medicine because of its anti-inflammatory properties. Ester-linked LAs are often avoided because of their alleged high allergenicity. Little data supports this assumption and hence the importance of our investigation on type-1 allergies against ester- and amide-linked LAs.
2021-5-17 · The amide group (lidocaine prilocaine mepivacaine etc.) is safer and hence more commonly used in clinical practice. The ester group (procaine tetracaine) has a higher risk of causing allergic reactions or systemic toxicity and is therefore reserved for patients with known allergies to drugs of the amide group.

A mnemonic device is that the names of amides contain 2 "i"s compared with only 1 "i" seen in esters. Remember One-eyed ester or Amide word has an "i" in it and hence an extra "i".
2019-9-17 · Abstract Local anesthetics have one of two chemical structuresesters or amides. Allergic reactions are far more common with ester anesthetics. In dermatology lidocaine an amide is by far the most commonly employed local anesthetic. When used within recommended dosage ranges local anesthetics are extremely safe. Vasovagal reactions are the most common side effect
2004-4-13 · Lidocaine is the most commonly used local anesthetic in the United States. It is an amino amide with a pKa 7.7 and a commercial preparation pH in the range of 5.6 when prepared without epinephrine. It has a rapid onset of action with intermediate duration.

Once inside the dermis ester and amide anesthetics possess the same mechanism of action. The anesthetic binds the voltage-gated sodium ion channel of the free nerve endings and blocks sodium influx. The blockade of sodium influx inhibits nerve cell depolarization and prevents propagation of nerve cell impulses along the nerve. Meechan JG.
