Surfactants are amphiphilic molecules of great interest in the pharmaceutical field due to their use in combination with other adjuvants to solubilize poor soluble drugs, improve their dissolution profile, promote permeation, increase drug delivery systems stabilization, among other characteristics. Literature shows that surfactants are included in several pharmaceutical forms composition: tablets, solid dispersions, emulsions, microemulsions, nanoemulsions, liposomes, and niosomes. This review aims to elucidate the different classes of surfactants based on their charges (cationic, anionic, nonionic, zwitterionic, and dimeric), the micelles formation process, and how surfactants molecules geometry can affect this phenomenon.
