non-steroidal anti-inflammatory drugs (nsaids), including selective cyclooxygenase (cox)-2 inhibitors, have come to play an important role in the pharmacologic management of musculoskeletal disorders. clinical trials have established the efficacy of etoricoxib in osteoarthritis, rheumatoid arthritis, acute gouty arthritis, ankylosing spondylitis, low back pain, acute postoperative pain, and pri...
The directly compressible floating-bioadhesive tablets of tramadol were formulated using varying amounts Carbopol 971P (CP) and hydroxy-propylmethyl cellulose (HPMC), along with other requisite excipients. In vitro drug release profile, floatational characteristics and ex vivo bioadhesive strength using texture analyzer were determined, and systematically optimized using a 3(2) central composit...
The purpose of the present study was to formulate and evaluate Berberine HCl Film coated tablet. Preformulation studies API were done. film tablets have advantages over conventional oral dosage forms, tablet also influences release drug after compression. coating help in making with good taste masking properties excellent mechanical strength. It revealed that cellulosic materials unable resist ...
Liquisolid system is a novel concept of dosage formulation for water insoluble drugs and lipophilic drugs via oral route. Formulation concept of liquisolid technology involves water insoluble drugs dissolved in suitable non-volatile liquid vehicles, and converted in to compact by blending with selective powder excipients. Liquisolid compacts are compressible powdered forms of liquid medications...
Two major forms of human carboxylesterase (CES), CES1A and CES2, dominate the pharmacokinetics of most prodrugs such as imidapril and irinotecan (CPT-11). Excipients, largely used as insert vehicles in formulation, have been recently reported to affect drug enzyme activity. The influence of excipients on the activity of CES remains undefined. In this study, the inhibitory effects of 25 excipien...
In situ forming intragastric controlled-release formulation is a new technology in the field of oral controlled-release delivery systems. The objective of this study was to develop formulations that can control drug release up to 24 hours. In addition, a combination of appropriate polymers and solvents was selected that could form a drug loaded gel at the process temperature of 60-70 °C, which ...
Submitted 2011.09.28. Accepted for publication 2011.12.19. The convenience of administration and improved patient compliance are important in the design of oral drug delivery system which remains the preferred route of drug delivery inspite of various disadvantages. One such problem can be solved in the novel drug delivery system by formulating “mouth dissolving tablets” (MDTs) which disintegra...
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 de...
In the present investigation, the compatibility of Atorvastatin calcium was evaluated with various superdisintegrants and other solid excipients by means of FT-IR and DSC. Several batches of tablets with varying proportion of superdisintegrants were prepared by direct compression techniques. Tablets were also evaluated for different physical properties and in-vitro drug release characteristics ...
a substantially lower number of drug formulations containing new molecular entities (NMEs) in the past decade (1). In 2008, the agency approved formulations containing 21 NMEs and four biologics, slightly higher than the 2007 total of 17 NMEs and two biologics. The growth between 2007 and 2008, however, was not enough to counter the marked downward spiral of drug approvals during the past 10 ye...
