Systemic drug delivery includes boluses of a semi-solid agar gel, each
containing active ingredients, packed singly or in co-operating sets in
blister packs, or loose in a container. When placed in the mouth the
bolus is disrupted, comes apart, and releases the active ingredients.
Sialogogues, flavours, and other additives assist in swallowing. Grains
of the active ingredients may be encapsulated inside harder gel capsules.
Active ingredients include over-the-counter medications and prescription
medications. Applications include self-medication particularly in
water--free situations such as public transport, medication for children,
stroke victims or the aged.
