SPI Pharma Reports Taste-Masked Ibuprofen

Feb 21, 2013 (Close-Up Media via COMTEX) -- SPI Pharma, Inc., a provider of pharmaceutical ingredients and technologies for patient-friendly dosage forms, announced the launch of Actimask Ibuprofen 92S, a taste-masked Ibuprofen.

According to a release, it joins Actimask Acetaminophen 92M in SPI's line of taste-masked actives specifically designed for making patient-friendly orally dispersible dosage forms economically in conventional equipment.

Actimask Ibuprofen 92S is manufactured via a 100 percent aqueous hydrogel coating system that provides taste-masking and rapid dissolution without the concern of residual solvents. The coating is readily wettable, while effectively masking unpleasant taste and preventing the characteristic "burning" sensation many patients experience with some Ibuprofen products. The wetting characteristics and a small particle size give Actimask both the smooth mouth feel and the organoleptic properties that are essential to formulating dispersible dosage forms.

While Actimask Ibuprofen 92S releases very little Ibuprofen in the mouth and throat, it releases in the GI tract, exceeding the compendial requirement of releasing no less than 80 percent in 60 minutes. However, the dissolution rate of Ibuprofen dosage forms does not always predict bioequivalence to reference drugs, so SPI conducted a 3-way cross-over pilot pharmacokinetic study comparing SPI's oral dispersible tablets and powder containing Actimask Ibuprofen 92S against a brand of Ibuprofen chewable tablet as the reference. Tablets were made with SPI's Pharmaburst 500 and the powder with Pharmasperse 416 delivery systems. The PK parameters for the Actimask dosage forms are similar to the reference product which provides assurance to developers/marketers that they can formulate bioequivalent Ibuprofen products.
