发明名称 Nicotine-containing, controlled release composition and method
摘要 A nicotine product having a nicotine release rate of not less than 70% over a 10 minute period as well as a process to produce such product. Such product is produced by a process comprising the steps of(a) preparing an aqueous solution of an organic polyol;(b) mixing said aqueous solution of the organic polyol with a cation exchange resin selected from the group consisting of (i)-a methacrylic, weakly acidic type of resin containing carboxylic functional groups (ii)-polystyrene, strongly acidic type of resin containing sulfonic functional groups and (iii)-polystyrene, intermediate acidic type of resin containing phosphonic functional groups thereby forming a cation exchange resin mixture having some of its ion exchange sites partially blocked with said polyol;(c) admixing with said mixture of step (b) an aqueous solution of nicotine to form a nicotine-coated cation exchange resin admixture; and(d) removing water from said admixture.The nicotine composition having a nicotine release rate of not less than 70% over a 10 minute period results.
