Drug Nanocrystals: Theoretical Background of Solubility Increase and Dissolution Rate Enhancement
Regardless of the administration route, the key factor for the success and reliability of any formulation is drug bioavailability, defined as the rate and extent at which the active drug is absorbed from a pharmaceutical form and becomes available at the site of drug action.1 Although metabolism and physiological factors highly affect drug absorption by living tissues, bioavailability is strong...
متن کاملMiniaturization of Drug Solubility and Dissolution Testings
Solubility and drug dissolution are of crucial importance for drug formulations. Poor water-solubility of drug candidates is a major obstacle in drug development, since the oral route is the most patient convenient and cost effective way to deliver drugs. In some cases the low aqueous solubility may limit the bioavailability when the absorption of the drug is dissolution limited. About 40% of t...
متن کاملCo-amorphous drug systems of carbamazepine: intrinsic dissolution rate improvements
Co-amorphous systems is one of the attractive strategies used to enhance the dissolution rates of poorly soluble drugs. This strategy has an additional advantage as it has the ability to overcome stability issues that may arise from the conversion of a crystalline drug into its amorphous form. In this study, quench cooling was used to prepare co-amorphous forms of carbamazepine (CBZ) with sacch...
متن کاملDissolution rate and apparent solubility of poorly soluble drugs in biorelevant dissolution media.
A series of poorly soluble BCS class II compounds with "grease ball" characteristics were assessed for solubility and dissolution rate in biorelevant dissolution media (BDM) with the purpose of investigating which molecular structures gain most in solubility when dissolved under physiologically relevant conditions. The compounds were studied in four media (simulated intestinal fluid in fasted (...
متن کاملEnhanced Solubility and Dissolution Rate of Raloxifene using Cycloencapsulation Technique
The aim of this study was to improve the water solubility of raloxifene by complexing it with sulphobutylether-β-cyclodextrin. Inclusion complexation in aqueous solution and solid state was evaluated by the phase solubility diagram, powder X-ray diffractometer, Fourier-transform infrared spectroscopy, nuclear magnetic resonance, scanning electron microscopy, hot stage microscopy and transmissio...
