Sucralose as co-crystal co-former for hydrochlorothiazide: development of oral disintegrating tablets

Development of oral disintegrating tablets requires enhancement of drug dissolution and selection of sweetener. Co-crystallization of drugs with inert co-former is an emerging technique for enhancing dissolution rate. The benefit of this technique will become even greater if one of the sweeteners can act as co-crystal co-former to enhance dissolution and mask the taste. Accordingly, the objective of this work was to investigate the efficacy of sucralose as a potential co-crystal co-former for enhancing the dissolution rate of hydrochlorothiazide. This was extended to prepare oral disintegrating tablets. Co-crystallization was achieved after dissolving hydrochlorothiazide with increasing molar ratios of sucralose in the least amount of acetone. The co-crystallization products were characterized using Fourier transform infrared spectroscopy, differential thermal analysis and powder X-ray diffraction. These measurements indicated that co-crystallization process started at a drug sucralose molar ratio of 1:1 and completed at 1:2. The developed co-crystals exhibited faster drug dissolution compared with the control, with co-crystal containing the drug with sucralose at 1:2 molar ratio being optimum. The later was used to prepare fast disintegrating tablets. These tablets had acceptable physical characteristics and showed fast disintegration with subsequent rapid dissolution. The study introduced sucralose as co-crystal co-former for enhanced dissolution and masking the taste.

Safety assessment of 16 sweeteners for the Korean population using dietary intake monitoring and poundage method

ABSTRACT

A sweetener is a food additive that imparts a sweet taste to food products. Sweeteners have been increasingly used in Korea since the approval of sodium saccharin and d-sorbitol in 1962. Unlike food contaminants, humans are exposed to food additives only through the consumption of processed food products. For exposure assessments of sweeteners, the dietary intakes of food products containing acesulfame-K, aspartame, saccharin-Na, and sucralose were determined, and the resulting calculated estimated daily intake (EDI) values were compared directly with each additive’s ADI. The poundage method was used to calculate the daily intake per capita for 12 additional sweeteners, such as lactitol, for which appropriate analytical methods for food products do not exist. The risk, as evaluated by comparing the EDI with the ADI, was determined to be 2.9% for acesulfame-K, 0.8% for aspartame, 3.6% for saccharin-Na, 4.3% for steviol glycosides, and 2.1% for sucralose. No hazardous effect was predicted for the other 11 sweeteners, including lactitol.
