Most of the oral dosage forms possess several physiological
limitations such as variable gastrointestinal transit because of
variable gastric emptying leading to non-uniform absorption
profiles, incomplete drug release and shorter residence time of the
dosage form in the stomach. This leads to incomplete absorption of
drugs having absorption window especially in the upper part of the
small intestine, as once the drug passes down the absorption site,
the remaining quantity goes unabsorbed.Since many drugs are well
absorbed in the upper part of the gastrointestinal tract, such high
variability may lead to non-uniform absorption and makes the
bioavailability unpredictable. Hence, a beneficial delivery system
to control and prolong the gastric emptying time and can deliver
drugs in higher concentrations to the absorption site to show local
action in the stomach requires a specialized delivery system. So
the purpose of this study was to lengthen the stay of drug in its
favorable absorption area and prolonging the release of the drug by
formulating it into an effervescent gastro-retentive drug delivery
system.
Ficus carica L. (Syn: Ficus sycomorous; family: Moraceae) is grows
in tropical and subtropical regions of India, used for varity of
purpose in traditional medicine. Ficus carica (anjeer) is an
indigenous plant to India, which finds its mention not only in
Indian system of medicine i.e.Ayurveda but also in other system of
medicine like Unani etc .The usefulness of this plant is
scientifically evidenced, and different biologically active
phytoconstituents are reported and also isolated from plant.Hence
the present attempt was undertaken to investigate the
microscopical, preliminary phytochemical studies including
qualitative and quantitative estimation and the diuretic activity
of Ficus carica to produce the scientific evidence and data at
preliminary stage.
