The present invention relates to a prolonged release formulation of caffeine, which comprises of caffeine embedded in a continuous phase of non-polymeric release controlling carrier. The formulation may be optionally comprised of one or more excipients which are acceptable in nutraceutical and food industry. The invention also relates to a process for preparation; wherein caffeine is uniformly distributed throughout the continuous phase of non-polymeric release controlling carrier to get single-phase granules. The formulation releases caffeine through continuous phase of non-polymeric release controlling carrier, wherein about 20 to 60% of caffeine is released in first hour, followed by about 50-90% of release in 4-8 hours and about 70 to 100% of caffeine release in 8-12 hours. Caffeine formulation can advantageously be administered to a subject for achieving stimulant effect through prolonged release of caffeine over entire day.

A method of treating or preventing dehydration in an individual having impaired swallowing such as dysphagia can include administering to the individual having the dysphagia an effective amount of a composition containing a salivating agent and a cooling agent in a weight ratio of 1:0.06 to 1:0.2. Optionally the composition includes a tingling agent. The composition can be a powder that is reconstituted before administration, for example at the point of consumption. A thickening or thin cohesive agent can be included in the powder and/or can be included in a liquid in which the powder is reconstituted. The composition can be a beverage containing the salivating agent and the cooling agent in a total amount of at least 3.0 wt. % of the beverage, for example at least 6.0 wt. % of the beverage. The composition can be a ready-to-drink beverage or a frozen dessert on a stick.
