The aim of present investigation was to develop press coated tablet for pulsatile drug delivery of ketoprofen using hydrophilic and hydrophobic polymers. The drug delivery system was designed to deliver the drug at such a time when it could be most needful to patient of rheumatoid arthritis. The press coated tablets containing ketoprofen in the inner core was formulated with an outer shell by d...

The investigation is to study the effect of polymers on compressibility and release of Metoprolol Tartarate from tablet through direct compression. Tablets were prepared by direct compression by mixing with commonly used polymers, Eudragit RL-100, Chitosan, Ethyl cellulose, Hydroxyethyl cellulose and hydroxypropylmethyl cellulose K-100 in 1:1 ratio. The compressibility parameters were estimated...

A multiparticulate system was developed using the coating pan method with nonpareil seed as the core material for the Theophylline. The drug loaded pellets were prepared by powder layering technique, sprinkling the drug on the nonpareil seeds using PVP K-30 in IPA as binder. The drug loaded pellets were coated by using polymers ethyl cellulose, EUDRAGITRS:RL (2:1) and EUDRAGIT® RS:RL (3:1). The...

Objective: The recent study's objective was to optimize and formulate a controlled-release gastro-retentive floating tablet of RG using central composite design, which provides continuous release Repaglinide for up 24 h. Methods: (RG-GRF Tablet) prepared by direct compression method. optimization carried out three-factor three-level Central Composite design. amount Eudragit RSPO (A), HPMC K-100...

Bearing in mind the present scenario of the increasing biological tolerance of bacteria against antibiotics, a time controlled two pulse dosage form of amoxicillin was developed. The compression coating inlay tablet approach was used to deliver the drug in two pulses to different parts of the GIT after a well defined lag time between the two releases. This was made possible by formulating a cor...

Raltegravir was the first HIV integrase strand-transfer inhibitor to be approved by the US FDA, in October 2007, for the treatment of HIV-1 infection in combination with other antiretroviral agents. Raltegravir can be used in treatment-naïve and -experienced patients, as well as for the treatment of multidrug-resistant infection. Raltegravir exists in two formulations: a film-coated tablet admi...

The vaginal route of administration is an alternative for several treatments for either local or systemic pharmacological effects. However, the permanence of a drug in this route represents a challenge for formulation development that can be overcome by using nanoencapsulation and chitosan gel. Thus, this work aimed to evaluate the performance of chitosan hydrogels containing cationic and anion...

Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor, primarily used for the treatment of hypertension, congestive heart failure, and heart attack. It belongs to BCS class III having a half-life of 12 hrs and 25% bioavailability. The purpose of the present work was to develop a press-coated, floating-pulsatile drug delivery system. The core tablet was formulated using the super-disint...

The objective of this research was to design a new colon‐targeted drug delivery system based on chitosan. The properties of the films were studied to obtain useful information about the possible applications of composite films. The composite films were used in a bilayer system to investigate their feasibility as coating materials. Tensile strength, swelling degree, solubility, biodegradation de...

We previously prepared and evaluated simple Eudragit S100 microparticles loaded with prednisolone (ES-MP) and Eudragit S100-coated chitosan-succinyl-prednisolone conjugate microparticles (Ch-MP/ES) in vitro. In this work, the effectiveness, toxic side effects (5 mg prednisolone (PD) eq/kg × 3 d, 10 mg PD eq/kg × 3 d), and pharmacokinetic characteristics (5 mg PD eq/kg) were examined using rats ...
