ABSTRACT
Variable drug release from the solid dosage forms has been an important cause of bioavailability problems.
The two main processes by which they release drugs are disintegration and dissolution. In the present study
the disintegration time of three immediate release dosage pain –relief tablets, Mefenamic acid-Drotaverine
HCl (250mg/80mg), Mefenamic acid- Dicyclomine HCl (250mg/10-mg tablets) , Ibuprofen-Paracetamol
(400mg/325mg) tablets indifferent beverages were compared with water. The beverages chosen were 6%
and 3.5% Milk, Soft drink, Butter milk and Fruit juice. The test was carried out using USP disintegration
test apparatus. The results showed that the disintegration time was highest in 6% milk then in 3.5% milk,
subsequently followed by fruit juices and butter milk .The disintegration was the least in the soft drink. The
addition of the USP disc to stimulate food weight on disintegration of IR tablets revealed that food weight
is not an important parameter in such a dosage form. These were all in comparison to its breakup in water.
From the above study it can be concluded that there is a variation in the disintegration time of the pain
relief tablets in different beverages. The highest variation was found when milk was the beverage. The
patients on these medications should be advised against consuming them with beverages slowing their
disintegration and in turn affecting their bioavailability.
