Handbook of Local Anesthesia (6e) p.103
"A vasopressor drug is included in most anesthetic cartridges to enhance safety and the duration and depth of action of the local anesthetic. The pH of dental cartridges containing vasopressors is lower (more acidic)
than that of cartridges not containing vasopressors (pH of 3.5 [3.3 to 4.0] vs. 6.5)."
