The characteristics of any medication format can depend on factors such as how it is delivered, how it is absorbed, and how easy it is for patients to use. Different formats — including tablets, capsules, and lozenges — each offer distinct characteristics that may be used in different situations depending on preference.
Lozenges (also known as troches) are designed to dissolve slowly in the mouth, and may be used as an alternative to traditional oral dosage forms.
What Are Lozenges?
Lozenges are solid dosage forms that dissolve gradually in the mouth.They are commonly used in applications involving the oral cavity and throat , and in some cases may allow for absorption through the lining of the mouth.
Key Differences at a Glance
| TABLETS | LOZENGES |
| Typically swallowed and absorbed through the digestive system | Dissolve slowly in the mouth |
| Faster disintegration | Dissolution occurs gradually over time |
| Absorption primarily occurs in the gastrointestinal tract | May be used in the mouth and throat |
| Usually unflavoured or lightly coated | Often flavoured to enhance palatability |
Gradual Dissolution and Localised Action
One of the distinguishing features of lozenges is their design to dissolve slowly, allowing ingredients to remain in contact with the mouth and throat for a longer period of time. This may make them an option where prolonged contact in the oral cavity is intended.
Absorption Pathways
Lozenges may allow some ingredients to be absorbed through the lining of the mouth (buccal or sublingual absorption). This route may bypass the digestive system for certain compounds, depending on their formulation and properties.
However, the extent of absorption varies depending on the specific ingredient and product formulation.
Ease of Use and Patient Preference
Lozenges may offer practical features for some individuals:
• Palatable format – Often flavoured to improve taste
• No water required – Can be taken without liquids
• Dosing convenience – Suitable for use on the go
• Alternative to swallowing tablets – May be considered by for individuals who have difficulty swallowing
Important Usage Considerations
Lozenges are designed to dissolve slowly in the mouth. Chewing or swallowing them wholemay alter how the product is delivered and alter how the ingredients are delivered.
Always follow the directions for use provided with the product or as advised by a healthcare professional.
Compounding and Customisation
In some cases, lozenges can be prepared by a pharmacist through compounding. This allows for formulations prepared in accordance with a prescription based on individual requirements, such as specific ingredient combinations or dosage adjustments, where appropriate.
Final Thoughts
Lozenges are a dosage form that may be used as an alternative to traditional oral dosage forms. While tablets and capsules remain widely used, lozenges may offer a convenient and an option depending on individual preference depending on individual preferences and needs.
