Insights

Children preferred strawberry-flavored carbocysteine oral solution over mint. This study used a facial action coding system to assess palatability in pediatric patients, finding strawberry taste more appealing.

Area of Science:

  • Pediatric Pharmacology
  • Sensory Science
  • Clinical Trial Design

Background:

  • Palatability of liquid medications is crucial for pediatric adherence.
  • Carbocysteine oral solutions are commonly prescribed for respiratory conditions.
  • Objective taste and preference data are needed to optimize pediatric formulations.

Purpose of the Study:

  • To compare the palatability of strawberry versus mint flavored carbocysteine oral solutions.
  • To evaluate the effectiveness of a facial action coding system for palatability assessment in children.
  • To determine children's taste preferences for pediatric pharmaceutical products.

Main Methods:

  • A randomized, triple-blind, crossover trial involving 42 healthy children aged 2-12 years.
  • Palatability assessed using the FaceReader™ facial action coding system for emotional valence.
  • Face-to-face interviews and taste preference rates collected for older children (5-12 years).

Main Results:

  • Strawberry-flavored carbocysteine showed significantly higher emotional valence scores compared to mint.
  • 69% of participants exhibited higher emotional valences for the strawberry preparation.
  • 88.5% of children aged 5+ preferred the strawberry taste, with 77.8% choosing it for re-administration.

Conclusions:

  • Strawberry-flavored carbocysteine oral solution is more palatable and better accepted by children.
  • The facial action coding system offers a viable, objective method for assessing pediatric product palatability.
  • Flavor optimization is key to improving medication adherence in pediatric populations.

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Gustation

Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

The Physiology of Taste01:24

The Physiology of Taste

The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

The Tongue and Taste Buds00:49

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
