Semi-solid foods and swallowing gels to help people who have trouble swallowing pills.

Influence of Swallow Gel and Semi-solid Consistency on Medication Dysphagia: A Multicenter Observational Study

Observational Heinrich-Heine University, Duesseldorf · NCT07254663

This project will test whether taking medications with semi-solid formulations or a commercial swallowing gel helps adults with dysphagia and healthy volunteers swallow pills more safely.

What this trial studies

This observational study uses flexible endoscopic evaluation of swallowing (FEES) as the diagnostic gold standard to document how often medication-related swallowing problems occur in people with dysphagia-associated diseases and in healthy controls. Participants will attempt medication intake with different consistencies, including semi-solid carriers and a commercially available swallowing gel, while clinicians record safety and bolus transport findings. The primary goals are to measure the prevalence of medication dysphagia and to compare whether alternative consistencies reduce penetration, aspiration, or residue during swallowing. Results aim to inform practical recommendations for safer medication administration in affected patients.

Who should consider this trial

Good fit: Adults with neurovascular, neurodegenerative, neuroinflammatory, neuromuscular, or ENT-related conditions who are clinically referred for FEES and can give informed consent, plus healthy adult volunteers without these conditions for controls.

Not a fit: People who cannot tolerate or undergo FEES, those with structural esophageal obstruction, or those with severe cognitive impairment preventing protocol participation are unlikely to benefit directly from this protocol.

Why it matters

Potential benefit: If successful, the findings could identify simple, safer ways to take pills that reduce choking, aspiration, and medication-related complications for people with dysphagia.

How similar studies have performed: Instrumental, systematic research on medication swallowing aids is limited; small reports and routine clinical practice suggest semi-solid carriers and gels may help, but large objective datasets are lacking.

Healthy Controls Adults without any dysphagia-associated disease (no neurovascular, neurodegenerative, neuroinflammatory, or neuromuscular disorders; no ENT-related diseases with structural abnormalities of the oropharynx or esophagus).

Capable of providing informed consent and cognitively able to follow the study protocol.

Exclusion Criteria:

No additional exclusion criteria beyond those specified in the inclusion criteria.
