Prilocaine (PLC)

Prilocaine is a local anesthetic of the amino amide type first prepared by Claes Tegner and Nils Löfgren. In its injectable form, it is often used in dentistry. It is also often combined with lidocaine as a preparation for dermal anesthesia, for treatment of conditions like paresthesia. As it has low cardiac toxicity, it is commonly used for intravenous regional anaesthesia (IVRA). In some patients, a metabolite of prilocaine may cause the unusual side effect of methemoglobinemia, which may be treated with methylene blue. Lidocaine and prilocaine topical cream is used on the skin or in the genital area to cause numbness or loss of feeling before certain medical procedures. It is used to prevent pain caused by an injection, the drawing of blood from a vein, or minor surgeries such as removing warts. This medicine contains a mixture of two topical local anesthetics. It deadens the nerve endings in the skin.
