NOVELTY – A pharmaceutical composition (C1), comprises at least one anesthetic and gelling agent, the composition having a minimum viscosity of 30 Pa.s, when subjected to a temperature of 5-50 degrees C. USE – In the dental treatment and dermatological treatment; and for treating pain (claimed). ADVANTAGE – The composition provides improved penetration of the anesthetic by maintaining the drug for a longer time and at a higher concentration on the action site, which increases the duration of anesthesia while reducing its toxicity, in addition to restricting the action of the drug to the application site. The maintenance of the drug for a longer time and at higher concentration on the action site is made possible as this anesthetic gel shows a smaller variation in its viscosity when subjected to a temperature increase resulting from the contact with the buccal mucosa. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is included for obtaining pharmaceutical composition (C1) involving micronizing the local anesthetic); adding a levigating agent; adding a gelling agent; adding a preservative and a wetting agent; and adjusting pH, through the addition of an alkalizing agent.
