This invention belongs to the field of
pharmaceutical formulation technology, specifically relating to a lozenge for refreshing the mind and freshening the breath, and its preparation method. The lozenge comprises a plain tablet and a shell. The plain tablet includes inner phase particles, an inner phase
particle coating layer, and excipients: the inner phase particles use
sodium carboxymethyl cellulose and crospovidone to construct an immediate-release framework, with immediate-release and sustained-release
caffeine and
theanine as stimulating ingredients, supplemented by
poloxamer to enhance penetration, achieving rapid absorption and sustained release of
caffeine, and the
theanine alleviates the
nerve stimulation caused by
caffeine; the inner phase
particle coating layer uses hydroxypropyl methylcellulose and
hydroxypropyl cellulose to construct a sustained-release framework, with
polyethylene glycol forming microporous channels to promote the sustained release of fermented ginsenosides, enhancing anti-fatigue ability to prolong the stimulating effect, and releasing
eucalyptol and
limonene to produce a cooling
sensation and
mask odor, supplemented by
Lactobacillus rhamnosus to inhibit the growth of harmful
bacteria in the mouth to reduce
odor, thereby achieving the effects of rapid stimulating, long-lasting mental
alertness, and fresh breath.
