The aim of this study was to develop self-nanoemulsifying drug delivery system (SNEDDS) of bosentan using quality by design (QBD) approach with better bioavailability. The major component of the formulation vis-à-vis lipid (Capmul MCM), surfactant (LABRASOL) and co-surfactant (PEG 600) were selected on the basis of saturation solubility. Mixture of LABRASOL and PEG 600 in the ratio of 1:1 showed better nano emulsifying region as depicted by pseudo ternary phase diagram. The optimum mixture of...

Background and Objective: Single-unit solid oral dosage forms such as tablets and capsules are considered the most common and acceptable form of immediate release systemic drug delivery systems. On the other hand, multiple-unit pellet systems (MUPS) have in recent years become an important dosage form that offers various advantages over conventional single-unit solid oral dosage forms.

Purpose of Review Faster aspart is a new formulation of insulin aspart (IAsp) produced by adding the excipients niacinamide and L-arginine. As this new, “ultra-rapid insulin” is available in the EU-market and Canada, the pharmacokinetic and pharmacodynamics data is summarized. Recent Findings Faster aspart shows an earlier onset of appearance of insulin in the bloodstream after subcutaneous administration and an earlier onset of glucose-lowering action and a higher glycemic effect within...

Abstract This study investigates the effects of micro-environment modification and polymer type on the in-vitro dissolution behavior and in-vivo performance of micro-environment pH modifying solid dispersions (pHM-SD) for the poorly water-soluble model drug Toltrazuril (TOL). Various pHM-SDs were prepared using Ca(OH)2 as a pH-modifier in hydrophilic polymers, including polyethylene glycol 6000 (PEG6000), polyvinylpyrrolidone k30 (PVPk30) and hydroxypropyl methylcellulose (HPMC). Based on the...

Abstract In the current study, we investigated the metoprolol absorption kinetics of an in-house produced oral sustained-release formulation, matrices manufactured via prilling, and two commercially available formulations, ZOK-ZID® (reservoir) and Slow-Lopresor® (matrix) in both New Zealand White rabbits and Beagle dogs, using a population pharmacokinetic analysis approach. The aim of this study was to compare the in vivo pharmacokinetic (PK) profiles of different formulations based on...

Abstract To develop a matrix-type, controlled-release tablet formulation of pelubiprofen (PLB), a recently developed non-steroidal anti-inflammatory drug, polymeric excipients including hypromellose, hydroxypropylcellulose, Eudragit® RS PO, and Kollidon® SR were screened. A formulation containing 12.4%w/w Kollidon® SR (K2 tablet) was found to be the most promising and stable for 6 months in an accelerated stability test. PLB release from K2 tablet was limited at pH 1.2, but gradually...

Abstract Objective: A novel multiparticulate system for the gastric delivery of Diltiazem (DTZ) was developed for effective treatment of hypertension. Materials and methods: Floating microspheres of ethylcellulose and Eudragit loaded with DTZ were successfully developed and evaluated for their gastro-retentive and controlled-release properties. The effect of various process variables on the particle morphology, micromeritic properties, in vitro floating behavior, percentage drug entrapment, and...

In this study a gastric-retentive delivery system was prepared by a novel method which is reported here for the first time. An innovative floating and bioadhesive drug delivery system with a hollow structure was designed and prepared. The floating and bioadhesive drug delivery system was composed of a hollow spherical shell, a waterproof layer (Stearic acid), a drug layer (Ofloxacin), a release retarding film (the novel blended coating materials) and a bioadhesive layer (Carbomer 934P) prepared...
