Studies on Interaction of SDS with HPMC Using Central Composite Design
Abstract: The conductivity measurements were used to study the interaction between non-ionic biopolymers, hydroxypropyl methyl cellulose (HPMC) and the anionic surfactant- sodium dodecyl sulphate (SDS) in aqueous solutions of different concentrations and at temperatures along with the use of Response Surface Methodology (RSM). Calculations were made of the free energies of aggregation ΔGagg, micellization (Gmic), and transfer (Gt), all of which are connected to the bonding interaction between the surfactant and …

Solubility Enhancement of Theophylline Drug Using Mixed Solvency Approach
Abstract: “Solubility enhancement” is one of the difficult tasks that have become a great challenge in formulation development of orally administered drugs having poor aqueous solubility. Poor aqueous solubility of drugs creates significant problems in producing formulations of sufficiently high bioavailability, thereby preventing the effective usage of these drugs. With the introduction of the concept of “mixed-solvency,” it is feasible to increase the solubility of poorly water-soluble drugs in aqueous solutions …
