Sweetening agents are chemical substances that are added to either mask the unpleasant taste or enhance the perception of a sweet taste in some oral pharmaceutical preparations such as tablets, syrup, suspension etc. Also, Sweetening agents are called sweeteners. Importantly, sweetening agents are the common excipient for Pediatrics.
Classification of Sweetening agents used in Pharmaceutical Preparations
Generally, Sweetening agents can be classified into two main categories:
- Plant-derived Sweetening agents: such as Erythritol, Lactitol, Maltitol, Mannitol, and Xylitol etc.
- Artificial Sweetening agents: such as Aspartame, Neotame, and Alitame etc.
Also, Sweetening agents can be classified into two main categories:
- Nutritive or caloric Sweetening agents: such as Glucose, Lactose, and Dextrose, etc.
- Nonnutritive or low-calorie Sweetening agents: such as Aspartame, Neotame, and Alitame etc.
List of Sweetening agents for Pharmaceutical Preparations
Name of Sweetener
Used Concentration (%) / Power/ Uses
|1. Acesulfame Potassium||Sweetening power is approximate 180–200 times that of sucrose, like aspartame.|
|2. Alitame||Approximately 2000 times sweeter than sucrose.|
|3. Aspartame||Sweetening power is Approximately 180–200 times that of sucrose. It is a dipeptide sweetener.|
|4. Dextrose||It is a simple sugar that is made from corn and chemically similar to glucose.|
|5. Erythritol||Use as Sweetening agent at concentration 0.5–3.0%|
|6. Fructose||Fructose is 50% sweeter than ordinary sugar.|
|7. Glucose||It is a simple sugar and the most abundant monosaccharide.|
|8. Lactitol||Also, It is used as a laxative and is used to treat or prevent constipation.|
|9. Maltitol||As sweet as sucrose.|
|10. Maltose||A dextrodisaccharide from malt and starch.|
|11. Mannitol||It is like xylitol or sorbitol.|
|12. Neohesperidin Dihydrochalcone||Approximately 1500–1800 times sweeter than sucrose and 20 times sweeter than saccharin.|
|13. Neotame||Structurally related to aspartame and is about 30–60 times sweeter than aspartame and 7000–13000 times sweeter than sucrose.|
|14. Saccharin||It is used at a concentration of 0.02–0.5% w/w Approximately 300–600 times sweeter than sucrose.|
|15. Sodium Cyclamate||In dilute solution, up to about 0.17% w/v, approximately the sweetening power is 30 times more than sucrose. Sodium cyclamate is used in combination with saccharin, often in a ratio of 10: 1.|
|16. Sorbitol||It is a polyhydric alcohol with about 1/2 sweetness of sucrose. It occurs naturally and also produced from glucose synthetically.|
|17. Sucralose||Approximately It has a sweetening power 300–1000 times that of sucrose and has no aftertaste.|
|18. Sucrose||Use as a Sweetening agent at a concentration of 67%|
|19. Compressible Sugar||The sweetener in chewable tablets at a concentration of 10 –50%|
|20. Confectioner’s Sugar||Sweetening agent in tablets at a concentration of 10 –20%|
|21. Tagatose||10% solution of tagatose is about 92% as sweet as a 10% sucrose solution.|
|22. Thaumatin||It is a naturally occurring intense sweetening agent approximately 2000–3000 times as sweet as sucrose.|
|23. Xylitol||It prevents production of acids by oral bacteria that damage the teeth’ surfaces.|
