Experimental and theoretical approach to cationic drug-anionic gemini surfactant systems in aqueous medium

- Strong synergism is shown by AMT and anionic gemini surfactant mixtures.
- Surfactants contribute more in mixed monolayer formation than in mixed micelles.
- 1H NMR studies support formation of mixed micelles.
- The mixed micellar formulation does not have any special requirement for storage.
