Chemically speaking, procaine is an aminoester derived from para-aminobenzoic acid.
In the past, procaine was part of the composition of pharmaceutical formulations suitable for both parenteral and topical administration. However, as of today (January 2019), commercially available procaine medicines are for topical use only (skin cream, ear drops, dental solution, and odontological drops). These medicines are classified as over-the-counter (OTC) drugs, therefore, they are allowed free sale in pharmacies and parapharmacies.
In drugs that contain it, procaine is normally present in the form of procaine hydrochloride and in some of them it is found in association with other active ingredients, such as phenazone (with anti-inflammatory action), benzocaine (also with an anesthetic action ) and "8-oxyquinoline sulfate (with antiseptic properties).
