Abstract
Ramipril termasuk BCS tipe II dengan kelarutan rendah sehingga
dapat menyebabkan disolusi yang buruk dan variasi bioavailabilitas.
Salah satu upaya peningkatan dilakukan dengan sistem campuran
interaktif, yaitu sistem pencampuran di mana partikel obat berukuran
micronized akan melekat pada permukaan partikel pembawa yang
ukurannya lebih besar. Mg stearat dan talk sebagai bahan pelicin
berperan dalam mempengaruhi mutu fisik dan profil disolusi tablet.
Penelitian ini bertujuan memperoleh formula serta proporsi optimum
magnesium stearat dan talk untuk menghasilkan tablet ramipril dengan
mutu fisik dan profil disolusi yang baik menggunakan Simplex Lattice
Design.
Penelitian ini menggunakan enam formula tablet campuran
interaktif ramipril dengan variasi perbandingan magnesium stearat dan
talk. Parameter yang diuji meliputi kekerasan, kerapuhan, waktu hancur,
dan disolusi. Tablet dibuat dengan metode kempa langsung (bobot 200
mg) dan data dianalisis menggunakan metode Simplex Lattice Design
melalui perangkat lunak Design Expert® versi 13 untuk menentukan
formula optimum.
Hasil penelitian menunjukkan bahwa peningkatan proporsi talk
pada tablet campuran interaktif ramipril dengan ukuran host 18/40 dapat
meningkatkan kekerasan, menurunkan kerapuhan, mempercepat waktu
hancur, serta meningkatkan profil disolusi tablet. Pada penelitian ini juga
diperoleh proporsi mg stearat dan talk optimum yaitu 0,527%:1,473%
yang memenuhi parameter kritis yang dievaluasi menggunakan metode
Simplex Lattice Design.
Ramipril belongs to BCS type II with low solubility, which can
cause poor dissolution and variations in bioavailability. One
improvement effort is carried out with an interactive mixing system,
namely a mixing system in which micronized drug particles will adhere
to the surface of larger carrier particles. Mg stearate and talc as lubricants
play a role in influencing the physical quality and dissolution profile of
the tablet. This study aims to obtain the optimum formula and proportion
of magnesium stearate and talc to produce ramipril tablets with good
physical quality and dissolution profile using Simplex Lattice Design.
This study used six ramipril interactive compound tablet
formulas with varying ratios of magnesium stearate and talc. Tested
parameters included hardness, friability, disintegration time, and
dissolution. Tablets were prepared using the direct compression method
(200 mg weight), and data were analyzed using the Simplex Lattice
Design method using Design Expert® version 13 software to determine
the optimum formula.
The results showed that increasing the proportion of talc in
ramipril interactive compound tablets with a host size of 18/40 increased
hardness, decreased friability, accelerated disintegration time, and
improved the tablet dissolution profile. The study also obtained the
optimum proportion of magnesium stearate and talc at 0.527%:1.473%,
which met the critical parameters evaluated using the Simplex Lattice
Design method.
