IN VITRO EVALUATION OF DISSOLUTION PROFILE OF TWO COMMERCIALLY AVAILABLE FOLIC ACID PREPARATIONS
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 3
Abstract
Objectives: Folic acid is a water-soluble B vitamin that is naturally present in some foods such as dark green leafy vegetables and dairy products, added to others such as fortified breads, and available as a dietary supplement. In a study performed in the United States, out of nine multivitamin products, only three products met US Pharmacopeia (USP) standard for folic acid dissolution. The aim of this study is to evaluate the dissolution profile of folic acid supplements in the United Arab Emirates according to the USP standards.Methods: Two commercial brands were collected from the market that are commonly prescribed. Water and citrate buffer (pH 6.0) were used as dissolution media.Results: Both products passed the dissolution testing of releasing the required amount of drug substance (75%) within 60 minutes. Also, both products contain an over age of up to 150% of the labeled amount to ensure the availability of the claimed amount.Conclusion: The study indicates that dissolution test is well established, reproducible, reliable and valuable tool for characterizing a drug product at different stages in its lifecycle. The use of citrate buffer showed a significant change in the release of folic acid from the tablets.Â
