Abstract :
Black cumin seeds (Nigella sativa L.) have ingredients such as essential oils that
can be used as an antidiabetic. Black cumin seed extract is formulated into
transdermal patches to avoid first pass effects and maintain drug bioavaibility, in
addition essential oils have low solubility so that transdermal patch are made to
increase bioavaibility. This study aims to determine the stability of the best
transdermal patch preparations for black cumin seed extract and to determine the
effect of variations in the concentration of HPMC on the physical stability test of
transdermal patch preparations for black cumin seed extract. Black cumin seeds
were extracted using the maceration method with 95% ethanol. Black cumin seed
extract was made into transdermal patch preparations using HPMC polymer with
a concentration of 6%, 7%, and 8%. The bases of patches obtained were subjected
to basic testing including pourability and drying time tests, while the obtained
patches were tested including organoleptic, weight uniformity of patch thickness,
folding resistance, percentage of water content, percentage of elongation, pH and
acceptability. Based on research, the black cumin seed extract formulation on
transdermal patch preparations showed that the addition of HPMC had the effect
of increasing the weight, thickness, pH and elongation percentage of the
Transdermal patch with a 6% HPMC concentration that had better physical
stability than other formulas with a patch weight of approximately 1,34 g ± 0,03,
the patch thickness is 0,03 mm ± 0,00, and the water content is 0% ± 0,00.
