Many people cannot swallow whole tablets and capsules. The cause ranges from difficulties overriding the natural instinct to chew solids/foodstuff before swallowing, to a complex disorder of swallowing function affecting the ability to manage all food and fluid intake. Older people can experience swallowing difficulties because of co-morbidities, age-related physiological changes, and polypharmacy. To make medicines easier to swallow, many people will modify the medication dosage form e.g....
Solid oral dosage forms (SODF) are drug vehicles commonly prescribed by physicists in primary and secondary cares, as they are the most convenient for the patient and facilitate therapy management. Concerns regarding unintended adhesion of SODF during oro-esophageal transit remain, especially in multimorbid patients, bedridden patients and patients suffering from dysphagia.
The compliance of patients to solid oral dosage forms is heavily conditioned by the perceived ease of swallowing, especially in geriatric and pediatric populations. This study proposes a method, based on an in vitro model of the human oropharyngeal cavity, to quantitatively study the oral phase of human swallowing in presence of single or multiple tablets.
