What is the difference between lidocaine hcl / lidocaine base and tetracaine hcl / tetracaine base?
Lidocaine / Lidocaine base is an alternative choice for those who are sensitive to ester-type local anesthetics.
Tetracaine base, a long-acting amino-ester, is more lipophilic than lidocaine, concentrating in the stratum corneum of the epidermis, where it slowly diffuses. But another very clear point is that tetracaine base is not easily soluble in water.
