The bioavailability of a generic diclofenac sodium sustained release tablet preparation (Zolterol, SR) was compared with the innovator product, Voltaren, SR. Twelve healthy adult male volunteers participated in the study, which was conducted according to a randomized, two-way crossover design with a wash out period of one week. The bioavailability of diclofenac was compared using the parameters...

objectives: postsurgical adhesion is one of the common complications after surgery. some anti-adhesion barriers are commercially available which are not customary used by physicians as much as expected because of ineffectiveness. recently, nanofibers have been introduced as anti-adhesion barriers with the potential of drug delivery. in the light of role of inflammation and oxidative stress in a...

DIETHYLPROPION ("Tenuate") has been shown to be useful in the treatment of refractory obesity (Seaton et al., 1961). Appetite suppression with the standard preparation is reported to last about four hours (Spielman, 1959) and the drug must be taken at least three times daily. This paper reports the use of a longacting preparation of the drug, which need be taken only once a day. It is marketed ...

Background: Green tea polyphenols (GTP) are known to have several health benefits. In spite of these benefits, its application as a therapeutic agent is limited due to some of its limitations such as stability, bioavailability, and biotransformation. To overcome these limitations, liposomal nanoparticles have been used as a carrier of the GTP. <spa...

Floating dosage forms with prolonged gastric residence time have garnered much interest in the field of oral delivery. However, studies had shown that slow and incomplete release of hydrophobic drugs during gastric residence period would reduce drug absorption and cause drug wastage. Herein, a spray-coated floating microcapsule system was developed to encapsulate fenofibrate and piroxicam, as m...

objective(s): ketotifen fumarate (kf) is a selective and noncompetitive histamine antagonist (h1-receptor) that is used topically in the treatment of allergic conditions of rhinitis and conjunctivitis. the aim of this study was to formulate and improve an ophthalmic delivery system of kf.ocular nanoparticles were prepared with the objective of reducing the frequency of administration and obtain...

conclusions it was shown that combination of pectin and eudragits can relatively control drug release in the upper gi. on the other hand, pectin degraded in the presence of pectinase and formulations were susceptible to the colonic media. results it was shown that in the presence of pectin, formulations without erl had a relative resistance to drug release in sgf. pellets containing pectin and ...

The purpose of the present investigation was to produce a quick/slow biphasic delivery system for metoclopramide hydrochloride using the superdisintegrant Ac-di-sol for the fast release layer and hydroxypropyl methylcellulose K100M and Ucarflock 302 to modulate the release of the drug. A dual component tablet made up of a sustained release and an immediate release layer was prepared by direct c...
