The present invention improves the bad taste of injected anesthetics and analgesics by incorporating a flavoring or cooling agent such as menthol into the parenteral composition. In the current practice of dentistry, injectable anesthetics are administered to provide comfort and a more desirable experience for the patient. Lidocaine, Carbocaine, Bupivacaine and other injectable anesthetics and analgesic drugs show a metallic/bitter aftertaste after injection. This taste can last up to 2 hours after the anesthetic dissipates. This taste is highly objectionable to all patients and in many it can cause upset stomach and sometimes nausea.
