Final answer:
The absolute MRD for Lidocaine with epinephrine is typically 500 mg per appointment, with variations based on patient weight and health conditions.
Step-by-step explanation:
The absolute maximum recommended dose (MRD) for Lidocaine with epinephrine is typically 500 mg per appointment. Lidocaine is a local anesthetic and epinephrine acts as a vasoconstrictor, which prolongs the duration of the anesthetic effect and reduces bleeding in the area where the drug is administered. The addition of epinephrine allows for a higher MRD of lidocaine compared to when it is used without epinephrine.
The MRD is determined based on a patient's weight and overall health condition, so it is important to consult with a healthcare provider before administering lidocaine with epinephrine. For most adults, the MRD of lidocaine with epinephrine is 7 mg/kg of body weight, not to exceed 500 mg per appointment.
