The purpose of this research was to prepare a floating matrix tablet containing domperidone as a model drug. Polyethylene oxide (PEO) and hydroxypropyl methylcellulose (HPMC) were evaluated for matrix-forming properties. A simplex lattice design was applied to systemically optimize the drug release profile. The amounts of PEO WSR 303, HPMC K15M and sodium bicarbonate were selected as independen...

The current research focused on screening and finding the significant independent variables in stavudine loaded tablet, followed by optimizing best formulation using central composite design. objective of study to develop controlled release tablet utilizing reduced factorial design, optimization technique as well characterization prepared tablets. Preliminary trial batches were different grades...

Kaposi's sarcoma (KS) associated herpesvirus (KSHV) is the etiological agent of KS. In vivo, KS is a tumor capable of spreading throughout the body, and pulmonary metastasis is observed clinically. In vitro, KSHV induces the invasiveness of endothelial cells. The KSHV open reading frame K15 is a KSHV-specific gene encoding a transmembrane protein. Two highly divergent forms of K15, the predomin...

This study aimed to produce a gastroretentive floating tablet of Metoprolol succinate and examine the effects release retardant on in vitro drug release. is β1 selective antagonist used as an Anti-hypertensive, Antiarrhythmic, Anti Angina. has 48% oral bioavailability due limited absorption from lower gastrointestinal tract. The tablets were designed increase stomach retention, prolong release,...

1(NAFETIC) Centre, University College of Pharmaceutical Sciences, Kakatiya University, Warangal 506 009, Andhra Pradesh, India. A b s t r a c t Ofloxacin (OFX) is a synthetic broad spectrum analog of second generation fluoroquinolone antibiotic. It is used for the treatment of urinary tract, prostate, skin, urinary and respiratory tract infections. Ornidazole (ORN) is a nitroimidazole derivativ...

Based on an elementary osmotic pump, controlled release systems of diclofenac sodium (DS) were designed to deliver the drug in a zero-order release pattern. Osmotic pump tablets containing 100 mg DS were prepared and coated with either semipermeable (SPM) or microporous (PM) membranes. The tablet coats were composed of hydrophobic triacetin (TA) or hydrophilic polyethylene glycol 400 (PEG 400) ...

In this study, aspirin (AS) and isosorbide 5mononitrate(ISM) sustained bilayer tablets were developed by wet granulation and compression technique, the influence of the contents of PVPP on the dissolution of AS from the tablets was investigated. An orthogonal experiment design was used to optimize ISM sustained release layer. The tablets were tested for their drug content, hardness, thickness, ...

Objective: To develop a Verapamil hydrochloride controlled release gastro-retentive (CRGR) tablet for once-daily dosing using the response surface Box-Behnken Design (BBD) approach improvement of bioavailability and reduction in frequency to overcome issues related conventional formulation. Methods: For optimization, 33Box-Behnken design was used. The independent variables were selected, amount...

Objective: Butorphanol is a commonly used medication for the management of postoperative pain and suffers low bioavailability high first-pass metabolism. The objective current studies was to develop butorphanol tartrate-loaded dissolving microneedle patch overcome limitation metabolism without causing any discomfort patient. Methods: prepared using Lapox resin micro-molds. optimized box-Behnken...
