Gel Preparation

The present research work is based on the formulation and evaluation of topical gel of Ibuprofen where Carbopol 940 is used as the polymer. Gels were prepared by dispersing the polymers  in a mixture of water and glycerol with methyl paraben as the preservative and the varying amount of ibuprofen, being kept under magnetic stirring until the homogeneous dispersion was formed. The dispersion was then neutralized and made viscous by the addition of triethanolamine. The Carbopol gels of Ibuprofen were found to be homogenous with good drug loading. The pH of all the gel formulations was found within the neutral pH range which is compatible with skin. And the viscosity of the formulations was found to be feasible for topical drug delivery. The drug content of the three formulations was found in the range of 87.56% to 90.45% which shows efficient drug loading. Results of In vitro drug release study showed that F5 formulation has better diffusion of drug through egg membrane and hence further permeation studies were carried out through rat epidermis. The compatibility study showed that the major peaks in FTIR spectra of the pure drug were found to be intact in their physical mixture. Hence there is no interaction between drug and Carbopol in their physical mixture. Carbopol can be effectively used as the polymer for topical gel preparation. And F5 formulation containing 0.5 % w/w Carbopol 940 may be effectively used as topical transdermal delivery for Ibuprofen. Keywords: Ibuprofen, Transdermal Gel, Drug release, Compatibility study

Aim: Formulation & Evaluation of Topical Gel of Acyclovir for Treatment of Viral Disease. Material & Methods: Acyclovir gels were formulated using different polymers like Carbopol 934, Carbopol 940, hydroxy propyl methyl cellulose and Sodium Carboxy methyl cellulose. Different concentrations of polymer were used in the formulation of gels. All the formulations were evaluated for the various parameters. Results & Discussion: Different formulations with use of different polymers were prepared. The amount and percentage of drug present in gel formulation using different polymers were estimated as per the procedure. The prepared gel using 1% carbopol- 934(A2) showed maximum drug content (101.72%) compared to other formulations. The spreadability of gels was determined as per the procedure. From spreadability data is observed that the formulation with 1.0% carbopol-934 showed maximum (8cm), where as the formulations with 1% carbopol-940, 3%, HPMC and Sodium CMC 3% were showed significant spreadability. 1.0 % carbopol-934 shows maximum release (74.59%). The addition of DMSO as permeation enhancer improves the drug release from gel formulation. 1.0% carbopol-940 also showed a similar release pattern, but the release was lesser. In case of HPMC and Sodium CMC gels the release was much lesser than carbopol gels. The addition of DMSO as permeation enhancer drug release was improved. Stability study for the best formulation was done as per the procedure. The gel was both physically and chemically stable at 4-50C, Room temperature and 37±50C. Conclusion: From this investigation, it was concluded that formulation A2 with 1% Carbopol-934 may be the best formulation having good in vitro release profile, stability and bioavailability. Based on the results from the study further utility of the dosage form may depend on pharmacokinetic data. Forthcoming research work of antiviral activity may contribute in the challenging area.

The present research work deals with the formulation and evaluation of in-situ gelling system based on sol-to-gel transition for ophthalmic delivery of an antibacterial agent gatifloxacin, to overcome the problems of poor bioavailability and therapeutic response exhibited by conventional formulations based a sol-to-gel transition in the cul-de-sac upon instillation. Carbopol 940 was used as the gelling agent in combination with HPMC and HPMC K15M which acted as a viscosity enhancing agent. The prepared formulations were evaluated for pH, clarity, drug content, gelling capacity, bioadhesive strength and in-vitro drug release. In-vitro drug release data of optimized formulation (F12) was treated according to Zero, First, Korsmeyer Peppas and Higuchi kinetics to access the mechanism of drug release. The clarity, pH, viscosity and drug content of the developed formulations were found in range 6.0-6.8, 10-570cps, 82-98% respectively. The gel provided sustained drug release over an 8 hour period. The developed formulation can be used as an in-situ gelling vehicle to enhance ocular bioavailability and the reduction in the frequency of instillation thereby resulting in better patient compliance.

Puffed Rice

In the present experimental investigation an attempt has been made to assess the utility of Crushed Puffed Rice (CPR)-High Molecular Weight Chitosan (HMWCH)-Hydroxypropyl Methylcellulose K15M (HPMC K15M) as a polymeric carrier for the sustained stomach delivery of Piroxicam (PRX). A total of nine formulations were prepared by using 3 (2) Taguchi factorial design, physically blending drug and polymer(s) followed by encapsulation into hard gelatin capsules size 1. The prepared capsules were evaluated for various performance such as weight variation, drug contents, in vitro buoyancy and drug release in 0.1 M HCl. The effect of drug loading on in vitro performance of the formulations was also determined. Crushed puffed rice (CPR) remained buoyant for up to average time span of 06 hr as an unwetted irregular mass in 0.1 M HCl. However, when combined with HMWCH or HPMC K15M or HPMC K15M + HMWCH a low -density cylindrical raft type hydrogel was formed which remained buoyant for up to 12 hr and released up to 99% drug in a sustained manner from 8 to 12 hr following zero order release kinetics. It was also observed that drug release from drug + CPR matrices followed Fickian mechanism. Combination of CPR + HMWCH or HMWCH + HPMC K15M also follows Fickian mechanism. Obtained data from the research work suggests that CPR in combination with HMWCH or HPMC K15M or HPMC has sufficient potential to be used as a carrier for stomach specific delivery of gastric irritant drug like PRX.Soni et al., International Current Pharmaceutical Journal, April 2018, 6(11): 61-80http://www.icpjonline.com/documents/Vol6Issue11/01.pdf

The objective of the present study is to formulate and evaluate ofloxacin emulgel. Emulgel formulations of ofloxacin were prepared using different concentrations of gelling agent’s Carbopol-940 and Xanthum gum. Tween-80 and span-80 were used as emulsifiers and propylene glycol as a humectant in the preparation of emulgel. The effect of the concentration of gelling agent on the drug release from the prepared emulgel was investigated. The compatibility study was conducted using Fourier-transform infrared (FTIR). The formulated emulgel was characterized by their physical appearance, pH determination, viscosity, spreadability, drug content, microbial test and in vitro diffusion study. FTIR indicated that the drug and excipients used in the study are compatible with each other. All the prepared formulations showed acceptable physical properties, homogeneity, consistency, spreadability, viscosity, and pH value. Drug release from all the formulations depended upon the concentration of the polymer used. As the concentration of Carbopol 940 increased the spreadability and drug release was found to be decreased. Emulgels formulated with oleic acid gave a much higher release rate of ofloxacin than emulgels formulated with liquid paraffin. The release of drug from all the emulgels prepared followed Zero-order kinetics. The linear Higuchi plots indicated that the drug release from all the emulgels prepared followed diffusion kinetics. Emulgel formulated with oleic acid exhibited greater flux when compared with those formulated with liquid paraffin. The formulations were found to be stable during stability testing. It can be concluded that Carbopol 940 and oleic acid are recommended for the formulation and preparation of Ofloxacin emulgels for topical drug delivery.
