A Review on Niosomes - A novel approach for drug targeting
No full textThis is a general review on niosome as drug carrier, which improves the bioavailability of drugs, increases penetration through skin, releases drug in a controlled or sustained manner, and used for targeting of drugs to specic sites in the body.Niosomal drug delivery system can be considered as an emerging novel drug delivery system, which consists of microscopic non-ionic vesicles composed of non-ionic surfactants. These are biodegradable, relatively nontoxic, more stable and inexpensive, and an alternative to liposomes. Methods of preparation, characterisation and application of niosomes have been reviewed. Niosome has potential to reduce the side effects of drugs and increase therapeutic effectiveness in various diseases. It can also be used as a carrier to deliver drugs topically. This review presents an overview of the types of niosomes, techniques of preparation of niosome characterisation and their applications
Inclusion of Hydrophilic-Lipophilic Balance (HLB) in the treatment of Psoriasis- A new approach
Get PDFThe present study highlights the importance of Hydrophillic-Lipophilic value of the base cream for the dermatological purposes beyond formulation stability. Hydrophilic- Lipophilic Balance (HLB) is largely considered for attaining stability of the base cream by the chosen emulsifier/ surfactants. However the base formulation (cream or ointment) also must act as an emulsifier to balance the hydrophilic- lipophilic ecosystem of the skin besides the formulation acts as the drug dispensing mechanism. Psorolin ointment for the treatment of psoriasis is being formulated with due diligence to HLB value due to the skin conditions of psoriasis. Details are presented in the paper
Formulation and Characterization of Zingiberol Loaded Microsphere for Motion Sickness
Get PDFThe present research work involve the development of Zingiberol as the treatment of motion sickness. The Zingiberol microsphere was formulated by Ionotropic gelation method using different polymers in different ratio depending on RSM method. The prepared formulations were optimized on the basis of dependent variables like particle size (mg), entrapment efficiency etc. The SEM photographs of Zingiberol microsphere before dissolution shows the spherical and smooth surface whereas after dissolution the pores and crevices were shown which is indicating that the microsphere are showing drug release by diffusion mechanism. The microsphere formulations were able to sustain the release of drug both in vitro and in vivo. In the stability studies no significant change in drug entrapment release characteristics of the microspheres
Simultaneous estimation of aspirin and omeprazole in laboratory sample by different UV spectrophotometric techniques
Get PDFThe aim of the present work is to develop simple, precise and economic UV- spectrophotometric methods for the simultaneous estimation of aspirin and omeprazole laboratory sample. The absorbance maxima (?max) for detection of aspirin and omeprazole were selected as 274 nm and 302 nm respectively for simultaneous equation method while wavelength range for detection of aspirin and omeprazole were selected as 270 nm - 276 nm and 300 nm - 305 nm respectively for area under curve method. Absorbance ratio method uses the ratio of absorbances at two selected wavelengths, one which is an isoabsorptive point and other being the ? max of one of the two components. From the overlay spectra of two drugs, it is evident that aspirin and omeprazole show an isoabsorptive point at 238.6 nm. Zero crossing first derivative spectrophotometry, where Aspirin showed zero crossing point at 301nm and Omeprazole showed zero crossing point at 274nm. Linearity for Aspirin was between 25- 125 ?g/mL and Omeprazole was 3-15 ?g/mL. These methods were successfully applied for estimation of Aspirin and Omeprazole in laboratory sample

The silymarin loaded gel shows the pseudoplastic flow from the rheogram. It shows Drug release 96.08% over a period of 3h. There was no acute skin irritancy found
A review on recent advancement in liquisolid techology
Get PDFLiquisolid technique is a novel process in which a liquid can be converted into a material that flows freely, is readily compressible. The carrier material in liquisolid compact comprises the liquid part, which is the liquid drug or a drug solution in liquid vehicles that are non-volatile. Solubility is the main parameter in the circulation of blood to achieve the whole concentration of the drug for pharmacological action. The rate of dissolution of drugs enhances in liquisolid technology. This in turn increases absorption and bioavailability subsequently. This review discusses the different advances and changes to improve liquisolid technology formulations and enhancement of dissolution rate of poorly soluble drugs. Most of the new chemical entities have high lipophilicity and poor water solubility, resulting in poor bioavailability. The release rate of these drugs should be increased in order to improve bioavailability. The technique is based on dissolving the insoluble drug in the solution loaded with non-volatile solvent. Then the dissolution rate of drug which is poorly soluble will rise. The enhanced bioavailability is due to the increased surface area of drug for release, increased drug aqueous solubility or improved wetting capacity
Formulation and evaluation of herbal face pack for glowing skin
Get PDFThe aim of this work is to formulate and evaluate an herbal face pack for glowing skin by using natural herbal ingredients. The natural herbal ingredients such as multani mitti, turmeric, sandalwood, saffron, milk powder, rice flour, orange peel were purchased from local market in the form of dried powder. The powder of banana peel was prepared by shade drying commercially, all powdered natural ingredients were sieved using #120 mesh, weighed accurately and mixed geometrically for uniform formulation and then evaluated for parameters including morphological, physicochemical, physical, phytochemical, irritancy along with stability examination. Thus, in the present work, we formulated a herbal face pack which can be easily made with the easily available ingredients. After evaluation, we found good properties for the face packs, free from skin irritation and maintained its consistency even after stability storage conditions. Results of the study scientifically verified that herbal face pack having enough potential to give efficient glowing effect on skin. The overall study is useful to substantiate product claims due its useful benefits on the human beings

The developed methods can be successfully applied in routine work for the estimation of Valsartan in its pharmaceutical dosage form
The Formulation Development & Evaluation of Econazole Nitrate Topical Emulgel
No full textTopical drug delivery has been used for centuries for the treatment of local skin disorders. Emulgel have emerged as one of the most interesting topical delivery system as it has dual control release system i.e. gel and emulsion. One side the topical applications of the drug offers the potential advantages of delivering the drug directly to the site of action and secondly delivering the drug for extended period of time at the effected site. The major objective behind this formulation is enhancing the topical delivery of hydrophobic drug (Econazole Nitrate) by formulating Econazole nitrate Emulgel using three types of gelling agents: water soluble polymer Carbopol 934, Carbopol 940 and Hydroxypropyl methylcellulose (HPMCK4M). Oleic acid is used as permeation enhancer. The prepared Emulgel were evaluated for their physical appearance, pH determination, viscosity, spreadability, extrudability, in vitro drug release, skin irritation test and stability. All the prepared Emulgel formulation showed acceptable physical properties, consistency, spreadability, viscosity and Ph value. The best Optimized formulation F1 compared with marketed Econazole Nitrate xiii cream. The in vitro release rate of Emulgel was evaluated using Diffusion cell containing Rat skin membrane with phosphate buffer pH 7.4 as the receptor medium. The release rate of the optimized F1 Formulation was found to follow Higuchi model. The Emulgel were found to be stable with respect to colour, pH, and drug content at room temperature and conditions for one month
