| Summary: | Nifedipine is a drug with a small solubility in water, a consequence, in order
to obtain the desired drug release, the solubility of nifedipine should be increased
by the addition of PVP K-30. This study was aimed to know the effect of HPMC
K15M, PVP K-30 on the release of nifedipin, and Avicel PH 102 on the floating
lag time of nifedipin floating tablet, and to find out the proportion of each
ingredient to produce the optimum formula of nifedipin floating tablet.
The study was conducted using Simplex Lattice Design (SLD) with 3
components i.e. HPMC K15M, PVP K-30 and Avicel PH 102 in order to obtain
14 formulas. The optimization parameter consists of absorption tablet, floating lag
time, C360 and DE360. The four parameters were analyzed using Design Expert
7.1.3 software to determine the optimum formula. The optimum formula was
obtained by determining the desired target for each parameter. The absorption was
selected in maximum target, floating lag time was selected in minimum target,
C360 targeted at number 54 and DE360 targeted at number 40.
HPMC K15M at the highest concentration affected the smallest release of
nifedipin, the highest PVP K-30 concentration affected the most of nifedipin
release, whereas high concentration Avicel PH 102 had a small affected reduce in
floating lag time of nifedipin floating tablet. The composition of the optimum
formula is as follows: 80 mg HPMC K15M, 97 mg PVP K-30 and 45 mg Avicel
PH 102. The results of tablet absorption, C360 and DE360 did not differ
significantly |
