Why is it important for medicines be palatable? Simply stated, medicines must be palatable to ensure dose acceptance and compliance.
Many drug actives are bitter – or have other “negative” or aversive attributes such as burning, malodors or gritty mouthfeel – making development of palatable drug products a daunting challenge.
Medicines are optimized for efficacy and safety, but often overlook the patient experience. Palatability is necessary to ensure dosing compliance, rather than to promote consumption, and is therefore of secondary importance.
Palatable drug products are those in which the aversive sensory attributes have been minimized or eliminated. In other words, they are not overly bitter, produce little trigeminal irritation, are smooth not gritty and have no perceptible malodors. It is an industry myth that flavor preference – orange, grape, chocolate or mint – is the primary determinant of palatability. In actuality it’s the degree to which the negative attributes have been eliminated, that’s the true measure of palatability.
The taste masking challenge of an API is a function of its time-intensity profile. The stronger the intensity and longer the duration of bitterness, or other aversive attributes, the greater the challenge.
Quantify the taste making challenge of your API early in clinical development.
The FlavorMetrics℠ Bitterness Profile provides quantitative data to inform formulation development.
Select the taste masking technology that is most appropriate for your formulation
Dose/response sensory analysis of APIs generates quantitative data to enable the selection, development and optimization of taste masking technology.
Measure the flavor quality of prototypes and competing products.
Patient acceptability of a drug product is a function of both its initial taste characteristics and the aftertaste it leaves behind. Both must be addressed otherwise palatability suffers. When palatability suffers so do patient adherence, health outcomes and product sales.
The FlavorMetrics℠ Palatability Profile is an empirical model that relates the quality of the initial flavor and aftertaste. It can be used to:
The data generated through a comprehensive taste assessment can directly inform the approach to taste masking, ensuring each formulation is designed for maximum palatability and patient adherence.
The client was developing an orally disintegrating tablet (ODT) form of an approved drug known to be extremely bitter. Senopsys conducted dose-response sensory analysis to establish the maximum free API concentration that could be effectively delivered in a palatable ODT and to evaluate the taste masking effectiveness of adsorption technology.
