Introduction

Flavoring medications is both an art and a science. It requires selecting appropriate flavoring and sweetening agents that improve palatability without compromising stability, compatibility, or safety.1 Compounding personnel should recognize that this process extends beyond adding just any flavoring and sweetening agents to a compounded preparation. Instead, flavoring involves understanding how to select and combine appropriate flavoring agent(s), namely one or more that complement the medication well, do not adversely affect the stability or compatibility of the formulation, and are preferable to the patient.1 The ability to appropriately flavor and sweeten medications is a crucial skill of pharmacy personnel that helps optimize patient adherence while ensuring the medication remains stable, safe, and effective. This continuing education activity will discuss various methods for flavoring and sweetening medications, describe these processes for pediatric and veterinary preparations, and compare available sweetening agents.

The Science of Flavor and Taste

Flavor perception is a complex sensory experience involving taste, smell, sight, and texture.1 Smell is extremely important for producing flavor. When an individual’s sense of smell is impaired, properly tasting medications becomes more challenging.1,2

There are five primary or basic tastes: bitter, sour, salty, sweet, and umami.2 Sweet tastes result from sugar or a sugar derivative such as fructose.2 Amino acids and alcohol in fruit juices can also elicit sweet tastes.2 Sour tastes result from acidic solutions, such as lemon juice, and the sensation of sour taste is due to the presence of hydrogen ions (H+) released by acidic substances when they come into contact with water. Salty tastes derive from salts.2 These include sodium chloride, potassium, and magnesium salts.2 Bitter tastes can be complex.2 Within sensory cells, 35 different proteins can detect bitter substances.2 Finally, savory or umami tastes are due to the presence of glutamic acid or aspartic acid.2 Examples of foods that contain glutamic acid include ripe tomatoes and cheese. Glutamate is often used to enhance flavors.2

The taste of a drug will be determined to an extent by its chemical composition.1 The chemical properties of various tastes and odors are detailed in Table 1.1

Flavoring Techniques

Compounding personnel can use various approaches to properly flavor compounded medications.1 Flavoring medications should involve a combination of appropriate flavor(s), namely one or more that complement the medication well, do not adversely affect the stability or compatibility of the formulation, and are preferable to the patient.1 No single approach is universally effective; flavoring strategies must be tailored to the formulation and patient.1

The following qualities describe a medication that has been appropriately flavored:1

Immediate flavor identity

Rapid full-flavor development

Acceptable mouth feel

Short aftertaste

No undesirable sensations

Clinical Application Tip

Rather than selecting a single flavor, combining complementary flavors (e.g., cherry + vanilla for bitterness) may improve palatability more effectively than a single agent.

Compounding personnel can choose among the following techniques to flavor medications, which are described in detail below: blending, overshadowing, physical methods, chemical methods, and physiological methods.1 When implementing these processes, it is important to recognize that the flavoring agent selected could cause more than one sensation for the patient.1 For example, saccharin often tastes bitter at first, then elicits a sweet flavor sensation.1

Blending involves using a flavor that complements the taste of the active pharmaceutical ingredient.1 For example, acidic drugs can be combined with citrus fruit flavors, such as lemon, lime, or orange.1 Bitter-tasting APIs can be blended with salty, sweet, or sour tastes.1 For sour-tasting APIs, salty tastes can be used to decrease the sour tones and enhance sweetness.1

Overshadowing (also called overpowering) is a process that involves using a flavor with a greater intensity than the API in the preparation.1 Wintergreen oil is an example of a flavoring agent used to overshadow.1

Physical methods can also be used to flavor medications. These include formulating an insoluble compound as a suspension because drugs cannot be tasted outside of a solution, placing the poor-tasting active pharmaceutical ingredient (API) in the internal phase as an emulsion and the flavoring agent in the external phase, and using high-viscosity fluids like syrups to keep the flavor in the mouth for a longer period of time.1

Chemical methods involve absorbing or complexing the drug with an ingredient that helps eliminate the API's bad taste.1

Physiological techniques include inducing a cooling sensation with an agent like mannitol, which occurs via its negative heat of solution.1 Alternatively, clove and cinnamon can be used, as they cause heat and numbness.1 This leads to a mild pain reaction and distracts from the medication's poor taste.1

The following tips are available to guide compounding personnel during the flavoring process:1

Select the proper flavor or flavor blends, and do not necessarily rely on what is traditionally used

Replace or adjust a vehicle if it is inadequate

Select a nonoffending preservative

Use artificial sweeteners in the proper amount and balance

Use desensitizing agents or flavor enhancers

Obtain the proper mouthfeel, such as smoothness that results in increased viscosity

Complement any bitterness with an acceptable bitter flavor, such as coffee, chocolate, or maple

Mask objectionable tastes by using the cooling effect of mint and the anesthetizing effect of spices

Use acids, such as tartaric, citric, and maleic, to enhance fruit flavors

In addition to understanding the techniques described above, compounding personnel should recognize that adding flavoring agents to a compounded preparation is not always benign and can affect the final preparation's stability and quality.1 Notably, flavoring agents can include numerous ingredients.1 For example, natural cherry flavor has more than 70 different components, and natural grape flavor has approximately 225.1 These ingredients and their potential effects on the final preparation should be considered when adding flavoring agents to a formulation.

Common Pitfalls in Flavoring Compounded Medications

Selecting flavors without considering drug–flavor interactions

Overuse of sweeteners leading to instability or adverse effects

Ignoring patient-specific conditions (e.g., diabetes, PKU)

Using xylitol in veterinary patients

Failing to document flavoring choices for future prescriptions

Table 3 provides a framework for taste masking strategies.1

Types of Flavoring Agents

Compounding personnel should be familiar with the definitions and associated properties of available flavoring agents.1 Categories of flavoring agents include natural flavors, artificial flavors, and spices.1 Table 3 describes these in more detail. Flavor agents can be obtained as dry powders or as oil- or water-soluble liquids.1 Water-soluble carriers include water, ethanol, propylene glycol, glycerin, and emulsifiers.1 Maltodextrins, corn syrup solids, modified starches, salt, and sugars are dry carriers.1 It is critical for compounding personnel to recognize that flavors exposed to light, temperature, headspace oxygen, water, and contaminants have the potential to degrade.1 During storage, flavors can adsorb to their containers and potentially sorb to any suspended materials within a preparation.1 Thus, these should be stored and utilized to preserve their integrity and quality.1

Natural Flavors

Essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating, or enzymolysis, which contains flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof whose significant function in food is flavoring rather than nutritional

Artificial Flavors

Any substance used to impart flavor that is not derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, fish, poultry, eggs, dairy products, or fermentation products thereof

Spice

That has a significant function in food as a seasoning rather than nutrition

That is true to name

That has had no portion of any volatile oil or other flavoring principle removed

Flavoring Preferences

While individuals will have their own preferences, compounding personnel can also select flavoring agents depending on the broader patient population. For example, female patients may be more sensitive to odors than males.1 Adult patients are more likely to accept a degree of bitterness within their medications compared to children, who prefer sweeter tastes.1 Another consideration is flavor fatigue, which may occur if a patient needs to take medication for an extended period of time.1 In these cases, it may be best to use milder flavors within the preparation. Table 5 details the flavor preferences of various patient populations.1 Flavoring considerations for pediatric and veterinary patients are discussed below.

Flavoring Medications for Pediatric Patients

Although unpleasant taste can help prevent accidental ingestion, it often reduces adherence in pediatric patients.3 Taking medications in the form of a pill or tablet is a useful way to cover the unappealing tastes, but this is not a viable option for children, as many are averse to swallowing pills, and the contents of pills cannot be broken up or crushed.3 Thus, the ability of personnel to appropriately flavor medications for children is crucial. Notably, children have more taste buds than adults, heightening unpleasant taste sensations.4 Flavor, odor, and texture (or mouthfeel) are all key factors when preparing oral medications for children.4 Research has found that sweet and salty flavors are preferable to children compared to adults.3 Children commonly prefer flavors such as grape, watermelon, and cherry.1

Pharmacy personnel can first check with caregivers about children’s flavor preferences, or have children sample one or more medication options. If a flavor is disliked, this should be noted, and the flavor should be changed for future prescriptions.

While adding sweeteners to children's medications may seem logical, pharmacy personnel should recognize that this is not always advisable. Pharmacy personnel should check with the caregiver and provider to ensure the selected sweetening agent(s) are safe and preferred.1,3 Caloric sweeteners can lead to numerous issues, including dental cavities, the potential over-consumption of medications that children find palatable, and harm to children who must reduce sugar intake, such as those with diabetes mellitus.3 Additionally, sorbitol can cause diarrhea and abdominal cramping in some patients. If a medication is prescribed for a long period, noncaloric sweeteners are recommended to help prevent tooth decay.4 Aspartame should be avoided in phenylketonuria.4

Case Example 1: Pediatric Adherence

A child refuses an antibiotic suspension due to its bitter taste. The pharmacist reformulates the preparation using a cherry flavor and a noncaloric sweetener. The patient completes the full course of therapy.

Case Example 2: Flavor Failure

A caregiver reports that a child refuses a flavored antibiotic despite the added grape flavor. The pharmacist reformulates using a cherry-vanilla blend and a viscosity-enhancing vehicle, improving adherence.

Pediatric Safety Considerations

Avoid excessive sugar in chronic therapy

Monitor for sorbitol-induced GI effects

Avoid aspartame in PKU

Consider the risk of overconsumption with highly palatable formulations

Flavoring Medications for Veterinary Patients

Veterinary patients also commonly require their medications to be flavored. Flavor selection for veterinary patients must balance palatability with stability and safety.1 Adding a flavoring agent should not alter drug bioavailability, solubility, or suspendability.5 In general, animals prefer flavors that mimic their normal diet. Birds tend to prefer sweet and fruity flavors.1 Besides flavor preferences, birds may also have texture preferences to consider. For example, certain birds prefer movement (like a wiggly worm) over a particular flavor.1,5 Dogs are omnivores who prefer meat and sweet flavors.1,5 Fixed oils are a great option for canines.1,5 Due to a lack of sweet taste receptors on their tongues, cats do not prefer sweet flavors and find bitter tastes disagreeable.1,5 They do better with flavors like tuna, liver, or marshmallow.1,5 Ferrets often prefer meat and fish flavors but enjoy sweet flavors.1,5 Gerbils like sweet and fruity flavors, while guinea pigs prefer vegetable-flavored preparations. Finally, rabbits prefer herb, vegetable, or fruit flavors.1,5 Table 7 details flavoring considerations for common animal species. Pharmacists should always consult the pet owner to determine any specific flavor preferences.

Guinea pigCarrot, celery, lettuce, pumpkin
RabbitBanana cream, carrot, celery, lettuce, parsley, pineapple, vanilla butternut

In addition to flavoring medications, pharmacists should also consider how best to sweeten their preparations. The following sweeteners (and recommended concentrations) can be used in veterinary preparations (Table 8).6 Xylitol should not be used in pet preparations, as it can cause serious health effects, especially in dogs.6 Xylitol can lead to hypotension, coma, and even death when consumed by dogs.6,7

Table 8

Sweeteners for Veterinary Compounds6

SweetenerConcentration
Acesulfame potassium0.1-0.5%
Steviol glycosides 95%0.1-0.6%
Stevioside 15%1-4%

Veterinary Safety Alert

Xylitol is highly toxic to dogs and can cause hypoglycemia, seizures, and death. It must never be used in veterinary compounded preparations.1

Sweetening Compounded Medications

Flavoring agents do not add sweetness to medications, so compounding personnel may also need to select appropriate sweetening agent(s) for the preparation.1 Sweetening agents are available in numerous forms, including liquid, solid, and semisolid.1 Like with flavoring agents, thoughtful consideration must be given to the most appropriate sweeteners.1 This includes considering both the formulation and patient-specific considerations.

Sweetening agents can be grouped into two categories: noncaloric and caloric sweeteners.1 These are detailed in Table 9. Noncaloric sweeteners can be 200-500 times sweeter than sucrose. There are some downsides to noncaloric sweeteners, including the bitter and somewhat unpleasant aftertastes associated with both saccharin and aspartame.1.9 Aspartame is also associated with stability issues if not kept between a pH of 3.4 and 5.1 Furthermore, many patients do not prefer to use artificial sweeteners due to potential safety concerns.8

Table 9

Examples of Sweetening Agents1

Caloric SweetenersNoncaloric Sweeteners

MannitolSucralose
FructoseAcesulfame K

Coloring Compounded Medications

While it is not necessary for medications to be colored, compounding personnel should be purposeful when selecting both the coloring agent and the ultimate color of the preparation.1 While coloring can be used, this will not improve the taste of the medication.1 Oftentimes, parents prefer that coloring agents not be used in their children’s medications. Some coloring agents have been associated with hypersensitivity reactions in pediatric patients, including angioedema, skin rash, vomiting, and dermatitis.4 There are also hypothesized links between coloring agents and hyperreactivity in children.10 Potential culprit agents include FD&C Yellow 5, Yellow 6, Red 36, Red 17, Blue 1, Blue 2, and Green 3.4 If a color is selected, it should preferably match the flavor of the medication–for example, a cherry formulation could be colored red–and documented on the compounding record to keep note for future prescriptions. Overall, pharmacy personnel must work with the patient’s provider and caregiver to determine flavoring and coloring preferences.

Regulations Pertaining to Flavoring Medications

An estimated 200 million medications have been flavored over the past 25 years, with no reported adverse events.10 Currently, most state pharmacy boards (49 of 52) have determined compounding does not apply to flavoring medications.10 However, the California Board of Pharmacy is looking to require stricter regulations regarding medication flavoring.11 It is important for pharmacy personnel to follow the rules and regulations of their state boards of pharmacy, as these boards enforce USP <795> standards.

Counseling Pearl

Patient and caregiver input on flavor preferences should be obtained at both the initial dispensing and refill visits to improve adherence.

Documentation Pearl

Flavoring and sweetening agents should be documented in the compounding record to ensure consistency for future refills and to support quality assurance.

Flavoring Myths

The following are common flavoring myths.9

Taste and aroma are the same

Taste is subjective and cannot be measured

A positive taste can be used to obscure a negative one

Only active pharmaceutical ingredients require taste masking

The most intense sweetener is the best sweetener

Flavor preference determines acceptability

Adult panelists cannot be used to guide the development of palatable pediatric drug products

Patient studies are effective in guiding formulation development

Solids and suspensions do not require taste masking

There is no well-defined process for developing palatable drug products

The Role of the Pharmacy Technician

In compounding pharmacies, pharmacy technicians play vital roles in ensuring the safe, high-quality, and effective preparation of compounded medications. With regard to flavoring and sweetening medications, pharmacy technicians may work with patients, parents, caregivers, and pet owners to determine flavor preferences when dispensing the initial prescription and refills. They may also assist in educating patients about the availability of specific flavors and whether a preferred flavor will work well with a particular formulation.

Summary

Flavoring has been described as both an art and a science, and it extends beyond merely adding flavoring and sweetening agents to a compounded preparation. It is critical that pharmacy personnel can properly flavor and sweeten medications. Doing so assists with patient adherence while ensuring the medication remains stable, safe, and effective. This involves selecting the appropriate flavor or flavor blend, using caloric and noncaloric sweeteners in the proper amounts and balance, and considering texture while maintaining proper mouthfeel.
