Oral Liquid Dispensing Routes
Oral delivery products can come in a range of formulation types including spray, drop, gel, or liquids designed for a variety of different oral delivery routes, each with their own advantages.
Orally ingested – Oral products for systemic applications can be designed for delivery by oral ingestion with absorption occurring through the gastrointestinal (GI) tract. This approach is commonly used for Consumer Health Care (CHC) oral liquids or syrups for indications such as cold & flu, analgesics, digestive aids or vitamins, minerals, and supplements (VMS).
Oral Topical – Some orally dispensed products are designed to target the mouth or throat locally. These can include products such as sore throat sprays, topical analgesics, oral disinfectants, mouth-ulcer, or soothing sprays.
Sublingual / Buccal – Oral liquid dispensed products such as VMS, can be formulated to be efficiently absorbed under the tongue or on the inside of the cheeks. This convenient delivery method has been utilized for vitamins such as melatonin or vitamin D and nicotine replacement therapy because it can accelerate the onset of action by avoiding the intestinal uptake pathway.
