Working Principle


Effervescent Tablet has advantages such as an improved taste and more gentle action in the stomach when compared with traditional pills. It also becomes more and more popular with patients.  But effervescent dosage is harder to make due to its larger size and complex production process.

It is common practice to add a lubricant in tablet compression. The function of the lubricant is to improve the flow of the material and to prevent tablets from sticking to the punches and dies. So magnesium stearate is very often used.  But in effervescent tablet production, magnesium stearate should not be used because they are insoluble in water. Strategies to overcome this problem are the use of other lubricants that are soluble in water (such as a mixture of spray-dried L-leucine and polyethylene glycol).
