Abstract: Anesthetics and other medical solutions are stored in a cartridge including a hollow body having a needle-penetrable septum at one end and a plunger at another end. A protective plug is inserted into the open plunger end of the cartridge and protects the cartridge from contamination per use. A buffer or other material may be injected into the cartridge, causing displacement of the protective plug, allowing the cartridge to then be used in a syringe or other delivery system. The anesthetic may contain at least one solute and have an initial tonicity and an initial pH. A volume of buffer may be injected through the septum into the anesthetic, where the initial solute concentration and initial pH of the anesthetic may be selected to provide a target pH and target tonicity after the buffer is introduced.

Abstract: System for the delivery of drugs from sealed cartridges provide for versatile and convenient delivery of the drugs. The system can be designed to deliver drugs from a plurality of cartridges with delivery through a manifold that connects to the plurality of cartridges. In some embodiments, the system mediates the heating of the drug such that it can be delivered at a temperature more closely approximating body temperature. In some embodiments, the composition of one cartridge is used to adjust the pH of the composition of the resulting mixture to achieve a desirable blended drug. The systems and procedures are particularly advantageous for the delivery of dental anesthetics.
