FORMULATION AND CHARACTERIZATION OF FLOATING BEADS OF ANTIBIOTIC BY EMULSION GELATION TECHNIQUE
Objective: The study aims at formulation and characterization of floating hydrogel beads of cefdinir for improving its bioavailability.
Methods: Cefdinir is broad-spectrum, oral, third-generation cephalosporin antimicrobial agent active against Gram-positive and Gram-negative bacteria. The floating hydrogel beads of cefdinir were formulated with polymers such as sodium alginate and sodium carboxymethyl cellulose by emulsion gelation technique using olive oil/castor oil. The beads were evaluated for surface morphology, bead size, entrapment efficiency, floating characteristics, in vitro swelling, in vitro drug release, and stability studies.
Results: On the basis of evaluation, all the beads show good swelling up to 12 h in 0.1 N hydrochloric acid. The swelling was followed by values in order of vegetable oil > mineral oil in case of emulsion gelation method. Scanning electron microscopy study shows that beads were spherical in shape. Comparing all the formulations, formulation FB12 was considered as optimized formulation which shows % yield 94.06±0.11, % floating 87.28±0.90, in vitro drug release 94.68, and also stable in stability studies.
Conclusion: From the findings, it may be concluded that cefdinir-loaded floating beads were successfully prepared and proved to be useful for the better bioavailability and patient compliance for enhanced antimicrobial activity
Methodologies and tools for OSS: current state of the practice
Over the years, the Open Source Software (OSS) development has matured and strengthened, building on some established methodologies and tools. An understanding of the current state of the practice, however, is still lacking. This paper presents the results of a survey of the OSS developer community with a view to gain insight of peer review, testing and release management practices, along with the current tool sets used for testing, debugging and, build and release management. Such an insight is important to appreciate the obstacles to overcome to introduce certification and more rigour into the development process. It is hoped that the results of this survey will initiate a useful discussion and allow the community to identify further process improvement opportunities for producing better quality software
FORMULATION AND EVALUATION OF MUCOADHESIVE BUCCAL PATCHES OF PIROXICAM
The main objective of present investigation to formulate and evaluate mucoadhesive buccal patches of Piroxicam, using solvent casting method. HPMC K100 M were used as a mucocoadhesive polymer and PEG 400 used as a plasticizer as well as penetration enhancers. The formulated patches of piroxicam were evaluated for their appearance, weight variation, thickness, folding endurance, surface pH, swelling index, drug content, % elongation, mucoadhesive strength, in vitro drug release, kinetic release study and stability study. Among all formulated batches (S1-S8) of buccl patches batch S6 showing maximum drug release after 8 hours 94.77 % and mucoadhesive strength 10.21±0.35g). The stability study optimized batch S6 doesn’t show any changes with respect to previous evaluation carried out before stability study. It may concluded the mucoadhesive buccal patches of Piroxicam were successfully prepared using HPMC K100 M by solvent casting method, evaluated & it is better alternative to conventional drug delivery for the management of pain and arthititis
DESIGN EXPERT SUPPORTED FORMULATION DEVELOPMENT, MATHEMATICAL OPTIMIZATION AND PREDICTABILITY STUDY OF FLOATING TABLETS OF BISOPROLOL FUMARATE
Objective: Focus of the study was to formulate Design expert Software assisted floating tablet of Bisoprolol Fumarate. Bisoprolol Fumarate is a Beta adrenergic blocking agent, used to treat cardiac diseases favorable characters to be formulated as sustained release Gastro retentive floating tablets.
Methods: Floating Tablets of Bisoprolol Fumarate were prepared by using polymers such as Polyox N 12 K and Carbapol 940 P. Formulations were prepared by using direct compression method and evaluated for various parameters like Hradness, thickness, weight variations, Floating lag time Total floating time,% drug release and Stability Study etc.
Results: FTIR spectroscopic study indicates no drug-excipients interaction in the prepared formulations. Hardness or crushing strength of the tablets of all the formulation was found between 5.8 and 6.5 kg/cm2. Floating lag time of all batches is in range of 1.18±2.0 to 2.43±1.6 (minutes). All other parameters of all batches are within an acceptable range. The polymer Carbopol 940 P had the significant negative effect of on the floating lag times. The In vitro dissolution profiles of optimized A3 Floating formulation of Bisoprolol Fumarate were found to sustain drug release 99.25 % up to 12 h with floating lag time of 1.45 min; Designed formulation was stable after Stability study. Optimization study was carried out by using 32 factorial designs to fabricate formulations.
Conclusion: It can be conclude that reproducible results of various parameters in this developed formulation can easily scale up. Furthermore designed formulation will be very effective for controlling blood pressure
