Abstract
Recently, solid lipid Nano-particles have received much attention by the researchers owing to
its biodegradability, biocompatibility and the ability to deliver a wide range of drugs. The aim of
the present study was to design Diltiazem solid lipid Nano-particles and to evaluate them.
Diltiazem solid lipid Nano-particles were prepared by hot homogenization technique using
different lipids (Tristearin, GMS and Comprital), soy lecithin as stabilizers and tween
80, Poloxamer as surfactants. The Nano-particles were evaluated for particle size & PDI, zeta
potential, entrapment efficiency and in vitro drug release. The particle size ranged from 49.7 to
523.7 nm. PDI of all formulations were good within the range of 0.189 to 0.427. The zeta
potential ranged from -10.5 to -29.6 Mv, Entrapment efficiency of all formulations were
observed was in the range of 78.68 to 95.23 %. The cumulative percentage release of Diltiazem
from different Diltiazem Nano-particles varied from 53.36 to 88.74% depending upon the drug
lipid ratio and the type of lipid used. The average percentage of drug released from different
SLNs after 24 hours showed in the following order: F9 (53.35%) < F6 (56.75%) < F4 (61.74%) <
F7 (63.8%) < F5(67.77%) < F8(69.04%) < F3(75.31%) < F1(79.36%)
