Individual layer weight control is a critical issue for bilayer tablets during manufacturing process. Despite its importance for ensuring product content uniformity, few studies have investigated the possibility of developing a process analytical technology (PAT) tool to monitor the individual layer control. We introduced the use of Terahertz time-domain measurement because of its fast measurem...

Purpose of Study: In the present study, an attempt was made to design and evaluate buccoadhesive bilayer tablets of granisetron hydrochloride (an anti-emetic drug), in order to overcome bioavailability problems, to reduce dose dependent side effects and frequency of administration. Method: Bilayer buccal tablets containing the drug were prepared by direct compression method using combination of...

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, ...

Multiple compressed tablets are compressed tablets made by more than one compression cycle. They are usually prepared to separate physically or chemically incompatible ingredients or to produce repeat or prolong action of drug. Compression coating perform similar functions as sugar or film coating except consists of dry coating concept hence prevents certain drawbacks of aqueous and non aqueous...

Bilayered tablet is an important pharmaceutical technology for the successful development of controlled release formulation along with various features to provide a way of successful drug delivery system. Bi-layer tablet is suitable for sequential release of two drugs in combination, to separate incompatible substances and also formulating sustained release tablet in which one layer is immediat...

In the last decade, interest in developing a combination of two or more Active Pharmaceutical Ingredients (API) in a single dosage form (monolithic or bilayer tablet) has increased in the pharmaceutical industry, promoting patient convenience and compliance. Bilayer tablets can be a primary option to avoid chemical incompatibilities between API by physical separation, and to enable the developm...

Bilayer tablets of Metformin hydrochloride and Glipizide were formulated. Glipizide is a poor water soluble (BCS class 2) antidiabetic drug. The present study aims to increase the solubility of Glipizide by solid dispersion technique using sodium starch glycolate and crospovidone as super disintegrants. Metformin hydrochloride was formulated by using Hydroxy Propyl Methyl Cellulose as the matri...

Bilayer tablets of aceclofenac sodium were developed using carboxymethylated white yam (Dioscorea rotundata) starch (CWY) for a fast release layer (2.5, 5.0, and 7.5% w/w), and acid-hydrolyzed bitter yam (Dioscorea dumetorum) starch (ABY) for a sustaining layer (27% w/w). Sodium starch glycolate (SSG) and hydroxypropyl methyl cellulose (HPMC) were used as standards. The starches were characteri...
