Use of a self-microemulsifying drug delivery system (SMEDDS) is widely known as one of the most effective approaches to overcome problems associated with low solubility and poor oral absorption of water-insoluble drugs. Previously, we have demonstrated that a super saturable SMEDDS (SuSMEDDS) greatly contributed to enhanced dissolution and oral absorption of valsartan (VST), a drug with poor solubility in water ...

Abstract Warfarin is intensively discussed drug with narrow therapeutic range. There have been cases of bleeding attributed to varying content or altered quality of the active substance. Factor analysis is useful for finding suitable technological parameters leading to high content uniformity of tablets containing low amount of active substance. The composition of tabletting blend and technological procedure were set with respect to factor analysis of previously published results. The...

The process, equipment, and technology for developing and manufacturing oral solid-dosage forms are well defined. Nonetheless, designing a drug product formulation that achieves the desired properties of the target profile both in magnitude and robustness is a multi-dimensional, and generally, constrained optimization problem, observes Aaron Goodwin, principal investigator, Research and Development, Capsugel.

Abstract Optimized orally disintegrating tablets (ODTs) containing furosemide (FUR) were prepared by direct compression method. Two factors, three levels (32) full factorial design was used to optimize the effect of taste masking agent (Eudragit E100; X1) and superdisintegarant; croscarmellose sodium (CCS; X2) on tablet properties. A composite was prepared by mixing ethanolic solution of FUR and Eudragit E100 with mannitol prior to mixing with other tablet ingredients. The prepared ODTs were...

Abstract Continuous manufacturing has attracted increasing research attention in the pharmaceutical industry within the last decade. Based on the extensive experimental studies, numerous modeling and computational approaches have been developed to capture the process information and make predictions. Moreover, flowsheet models have been built to simulate the dynamic behaviors of a plant-wide manufacturing process with respect to different process input factors. However, there still lacks a...

Abstract In this study, the anticancer drug letrozole (LTZ) was formulated using chitosan nanoparticles (CS-NPs) with the crosslinking agent sodium tripolyphosphate (TPP). The nano-formulation was optimized by varying the concentration of drug. The prepared particles were characterized using FTIR, TGA, XRD, SEM, TEM and DLS. From the FTIR results, the appearance of a new peak for double bond; length as m-dashCsingle bondH, Cdouble bond; length as m-dashC and Cdouble bond; length as m-dashN...

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: Background: Colorectal carcinoma is the fourth most common internal malignancy; it is second only to carcinoma of the lung as a cause of carcinoma death. 6-Mercaptopurine (6-MP) is a drug of choice in the treatment of Crohn's disease, ulcerative colitis and colorectal cancer. The drug shows irritation on gastric exposure. It has poor bioavailability with half life less than 2 h. Targeted delivery of 6-MP will provide an effective and safe therapy for colon diseases. Objective:...

Abstract Cosmetic skin care products currently in the market demonstrate an increasing trend towards antiaging products. Selection of the right formulation approach is the key to successful consumer acceptance. Nanostructured lipid carriers (NLCs) for dermal application can render added benefits to the formulation. Tretinoin a derivative of vitamin A, is a retinoid with anti-aging and anti-acne potential. The present study was aimed at formulating NLCs of tretinoin for reducing the skin...

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...
