cocrystal Sodium lauryl sulfate SLS also known as Sodium dodecyl sulfate SDS is an anionic surfactant and Tween 80 Polysorbate 80 is a nonionic surfactant both of which have been widely used in various drug dosage forms to control wetting stability and solubilisation of hydrophobic

Oct 11 2013 · The influence of the surfactants of sodium lauryl sulfate SLS and Tween 80 on carbamazepine nicotinamide CBZ NIC cocrystal solubility and dissolution behaviour has been studied in this work The solubility of the CBZ NIC cocrystal was determined by measuring the eutectic concentrations of the drug and the coformer

In a solid dosage form a tranilast complex or cocrystal of the invention may be admixed with at least one pharmaceutically acceptable excipient such as for example sodium citrate or dicalcium phosphate or a fillers or extenders such as for example starches lactose sucrose glucose mannitol and silicic acid b binders such as for

Cocrystal solubility stability and eutectic points were investigated as a function of pH and sodium lauryl sulfate concentration for a series of carbamazepine cocrystals in water The cocrystals represented two stoichiometries 1 1 and 2 1 and four coformers salicylic acid saccharin 4 aminobenzoic acid and succinic acid with various

Solubility the phenomenon of dissolution of solute in solvent to give a homogenous system is one of the important parameters to achieve desired concentration of drug in systemic circulation for desired anticipated pharmacological response Low aqueous solubility is the major problem encountered with formulation development of new chemical entities as well as for the generic development
