Tolperisone hydrochloride has a short elimination half- life and rapidly absorbed from gastrointestinal tract.2 If it is formulated by conventional tablets, it will require multiple daily administrations (2-3 times daily) which ultimately results into in conveniency to the patients and possibility of reduced compliance with prescribed therapy. Tolperisone HCl is more stable in acidic medium (pH > 4.5),and in alkaline medium (pH 4 to 7) tolperisone breaks down into 4-MMPPO and piperidine. Thus, the patient is exposed to an uncontrollable quantity of...

Famotidine is histamine -H2 receptor antagonist. It has bioavailability of 40 to 45% and it has shorter plasma half life of 2.5 to 3.5 hrs. The effective treatment of erosive esophagitis and Zolinger-Elisons syndrome requires administration of 20 mg of Famotidine 4 times a day. A conventional dose of 20 mg can inhibit gastric acid secretion up to 5 hours but not up to 10 hours. An alternative dose of 40 mg leads to plasma fluctuations; thus a sustained release dosage form of famotidine is desirable. Direct access to the systemic circulation bypasses drugs from the hepatic first pass...

In the present investigation, solid dispersion of olanzapine has been prepared to improve its solubility. Further, using solid dispersion, mouth dissolving tablet was prepared to overcome the problem of swallowing. A Simplex Lattice design was applied using three factors, i.e. superdisintegrants like croscarmellose sodium(X1) crospovidone(X2), and sodium starch glycolate(X3) in tablet formulation. Disintegration time, Wetting time, Water absorption, T50 (Time required to 50% drug release) and Q10 (percentage of drug released in 10 min.) taken as responses. Solid dispersion showed significant...

The objective of this study is to develop controlled porosity osmotic pump tablet of Verapamil Hydrochloride, which is an antihypertensive candidate, using Polyethylene glycol (PEG) 400 as pore former in Cellulose acetate semipermeable membrane and Mannitol as a osmotic agent which release drug for extended period of time (24 h) and drug release of optimized formulation is independent of pH and agitation speed with zero order release.

Itopride, a novel prokinetic agent is unique and different from the available prokinetics because of its dual mode of action and lack of significant drug interaction potential. Itopride is a newly developed prokinetic agent, which enhances gastric motility through both anti-dopaminergic and anti-acetylcholinesterage actions. It is best candidate for Gastro Esophageal Reflux Disease. Itopride 50mg can be given thrice in a day for Treatment of GERD. By developing the sustain release formulation of Itopride hydrochloride, the frequency of drug can be reduce to once only to obtain good...

The purpose of this research was to formulate tasteless complexes of Fexofenadine Hydrochloride with Kyron-134 and to formulate tasteless complex into fast-Dispersible tablets (FDT) for the treatment of allergic rhinitis & chronic idiopathic urticaria. Drug release from FDT in salivary pH was insufficient to impart bitter taste. Complete drug release was observed at gastric pH. The studies indicate that the formulation was taste masked drug can be formulated in to FDT with view to enhance patient compliance & to obtain faster onset action of the drug which would be advantageous in comparison...

To develop sustained release matrix tablet of Tramadol HCl that deliver drug for 24 hr and to be taken once in a day. Drug having high solubility and relatively shorter half-life suggests its suitability for an extended formulation. If it is formulated by conventional tablets, it will require multiple daily administrations which ultimately results into inconveniency to the patients and possibility of reduced compliance with prescribed therapy. Also fluctuation in plasma drug concentration leads to exaggerated side effects, this all limitations can be minimized by adopting extended release...

The purpose of this study was to develop and evaluate a drug delivery system in vitro based on a compression coated tablet containing 5-fluorouracil (5-FU) in core and pectin Hydroxypropyl Methylcellulose (HPMC) mixture in coat layer. The main reason for selecting pectin was its biodegradation in colon by colonic flora. On other hand, high molecular weight HPMC increases mechanical strength of tablet coat around a drug core during its transportation in gastro-intestinal tract. Multiple regression analysis with two way ANOVA revealed that both factors had statistically significant influence...

The idea for writing this basic HPLC book was probably born during the project sanctioned by University Grants Commission - Pune. This book was written as an updated reference guide for busy laboratory analysts and researchers. Topics covered include HPLC operation, method development and validation aspects. This book can serve as a supplementary text for students pursuing a career in analytical chemistry. It describes basic theories and terminologies for the novice and reviews relevant concepts, best practices, and modern trends for the experienced practitioner. A reader with a science...
