Abstract Spironolactone is a drug derived from sterols that exhibits an incomplete oral absorption due to its low water solubility and slow dissolution rate. In this study, formulations of spironolactone with four disintegrants named as croscarmellose sodium, crospovidone, sodium starch glycolate and microcrystalline cellulose II (MCCII) were conducted. The effect of those disintegrants on the tensile strength, disintegration time and dissolution rate of spironolactone-based compacts was...

ABSTRACT Objective: In the present study, our objective was to develop porous osmotic pump tablets of an anti-Parkinson’s agent, ropinirole. It also aimed to demonstrate the applicability of factorial designs and there by a statistical optimization in developing a controlled drug releasing device. Methods: A 32 factorial D-optimal study design was adopted to identify an optimized formulation. Tablets were prepared by direct compression using varying amounts of microcrystalline cellulose (MCC)...

Abstract: A double layer-coated colon-specific drug delivery system (DL-CDDS) was developed, which consisted of chitosan (CTN) based polymeric subcoating of the core tablet containing citric acid for microclimate acidification, followed by an enteric coating. The polymeric composition ratio of Eudragit E100 and ethyl cellulose and amount of subcoating were optimized using a two- level factorial design method. Drug-release characteristics in terms of dissolution ef ciency and controlled-release...

Abstract Fast dissolving tablets (FDTs) have received more interest in the pharmaceutical industry for those categories of drug which show slow dissolution and less oral bioavailability. Nowadays various technologies have been developed for FDTs with improved patient compliance and convenience. FDTs tablets provide an advantage particularly for the pediatric and geriatric patients who have difficulty in swallowing and also for that who are travelling for a long and suffers from lack of water...

Abstract This study aimed to apply quality risk management based on the The International Conference on Harmonisation guideline Q9 for the early development stage of hot melt coated multiparticulate systems for oral administration. N-acetylcysteine crystals were coated with a formulation composing tripalmitin and polysorbate 65. The critical quality attributes (CQAs) were initially prioritized using failure mode and effects analysis. The CQAs of the coated material were defined as particle...

Palonosetron HCl is a 5HT3 antagonist licensed for the prevention of acute chemotherapy-induced nausea and vomiting (CINV) associated with highly emetogenic chemotherapy agents (HEC) and the prevention of CINV associated with moderately emetogenic cancer chemotherapy (MEC). It has a substantially longer half-life (Approximately 40 h). So, it was plan to prepare melt in mouth tablet which could rapidly dissolved and absorbed which may produce rapid onset of action. Melt in mouth tablets were...

Abstract In dental practice, local anesthesia causes pain, fear, and stress, and is frequently the reason that patients abandon treatment. Topical anesthetics are applied in order to minimize the discomfort caused by needle insertion and injection, and to reduce the symptoms of superficial trauma at the oral mucosa, but there are still no efficient commercially available formulations. Factorial design is a multivariate data analysis procedure that can be used to optimize the manufacturing...

Abstract The colon is a promising site for drug targeting owing to its long transit time and mild proteolytic activity. The aim of this study was to prepare new low methoxy amidated pectin/NaCMC microspheres cross-linked by a mixture of Zn2+ and Al3+ ions and test their potential for colonic targeting of progesterone. A 24 factorial design was carried out to optimize the preparation conditions. High drug entrapment efficiency (82–99%) was obtained and it increased with increasing drug...

To evaluate the influence of different variables on tablet formulations containing enalapril maleate and indapamide as active substances, two separate experimental designs were employed: one for evaluating powder properties and the other for tablet characteristics. Because of the low active pharmaceutical ingredient content, it was hypothesized that both powder and tablet properties could be determined only by the characteristics of excipients. In order to test this assumption, both...
