Abstract
Ibuprofen (IBU) is one of the most commonly used nonsteroidal
anti-inflammatory drugs with high permeability
and low solubility. The aims of this research is to improve the
solubility and dissolution of the IBU by reducing particle size
using ultrasonic spray drying method and utilizing watersoluble
polymer (polyvinyl alcohol (PVA)) and surfactant
(sodium lauryl sulphate (SLS)) for particles formulation. The
results showed that increasing amount of PVA, smaller particle
size of as-prepared IBU-PVA-SLS was obtained, 6.3-fold smaller
than untreated IBU. The in vitro drug release study for simulated
gastric fluid without enzymes (0.1 N HCl or Buffer pH 1.2)
shows the dissolution of prepared IBU-PVA-SLS significantly
increase 2.4-fold higher than untreated IBU for dissolution
time of 30 minutes. While the solubility of the IBU-PVA-SLS
was increased 4.7-fold compare to untreated IBU. In general,
IBU possessing relatively high dissolution in intestinal fluid. In
contrast, the finding of recent investigation on dissolution of
IBU-PVA-SLS is significantly increase in gastric fluid, either due
to smaller particles size or PVA-SLS. Thus, despite the PVA and
SLS determine the particles formation during polymerization
yielding smaller particle size, they also responsible for effective
drug delivery system. It was concluded that PVA and SLS
in ultrasonic spray drying technique for IBU preparation
successfully reduces the particle size and effectively enhances
the solubility and dissolution rate of poorly water-soluble IBU
in 0.1 N HCl.
