The poor bioavailability and the therapeutic effectiveness exhibited by the anti-depressant venlafaxine hydrochloride on oral administration is overcome by the use of ion-activated gel forming systems that are instilled as drops; these undergo gelation in the nasal cavity. The present study describes the design, characterization and evaluation of mucoadhesive nasal in situ gelling drug delivery of venlafaxine hydrochloride using different polymers like sodium alginate, HPMC and pectin in various concentrations. DSC studies revealed compatibility of the drug and excipients used. The in situ gels were characterized for physicochemical parameters, gelling ability, rheological studies, drug content, drug entrapment efficiency, in vitro mucoadhesive strength, water holding capacity, gel expansion coefficient and in vitro drug release studies. The amount of polymer blends was optimized using 23 full factorial design. The influence of experimental factors on percentage cumulative drug release at the end of 2 and 8 hours were investigated to get optimized formulation. The responses were analyzed using ANOVA and polynomial equation was generated for each response using multiple linear regression analysis. Optimized formulation, F9, containing 1.98% w/V sodium alginate, 0.64% w/V hydroxylpropyl methylcellulose, 0.99% w/V pectin showed percentage cumulative drug release of 19.33 and 80.44 at the end of 2 and 8 hours, respectively, which were close to the predicted values. The optimized formulation was subjected to stability study for three months at 300C /75% RH. The stability study revealed no significant change in pH, drug content and viscosity. Thus, venlafaxine hydrochloride nasal mucoadhesive in situ gel could be successfully formulated to improve bioavailability and to target the brain.

Objective: The objective of the present work was to conduct accelerated stability study as per international council for harmonisation (ICH) guidelines and to establish shelf life of controlled release dosage form of ropinirole hydrochloride and pramipexole dihydrochloride microspheres for a period of 6 mo.Methods: Most optimized batch of ropinirole hydrochloride and pramipexole dihydrochloride (F12 and M12 respectively) were selected and subjected to exhaustive stability testing by keeping the sample in stability oven for a period of 3 and 6 mo. Various parameters like surface morphology, particle size, drug content, in vitro drug release and shelf life were evaluated at 3 and 6 mo period. The surface morphology of the formulated microspheres was determined by scanning electron microscopy (SEM). The particle size of the microspheres was estimated by optical microscopy method. The drug content was assayed by the help of ultra-violet spectrophotometer (UV). The in vitro drug release was performed by using Paddle II type dissolution apparatus and the filtrate was analyzed by UV spectrophotometer. The shelf life of the optimized microspheres was calculated by using the rate constant value of the zero-order reaction.Results: A minor change was recorded in average particle size of F12 and M12 microspheres after storage for 6 mo. For F12 and M12, initially the particle size was 130.00 µm and 128.92 µm respectively and after 6 mo it was found to be 130.92 µm and 128.99 µm respectively. There was no change in surface morphology of F12 and M12 microspheres after 6 mo of storage. The shape of microspheres remained spherical and smooth after 6 mo. An insignificant difference of drug content was recorded after 6 mo compared to the freshly prepared formulation. For F12 and M12, 94.50% and 93.77% of the drug was present initially and after 6 mo 94.45% and 93.72% of the drug was recorded. In vitro drug release was recorded after 6 mo for F12 and M12. Initially, 97.99% and 97.69% of the drug was released till 14th hour respectively for F12 and M12. After 6 mo, 98.23% and 97.99% of the drug was released respectively. The percentage residual drug content revealed that the degradation of microspheres was low. Considering the initial percentage residual drug content as 100%, 99.94% of the drug was recorded for both F12 and M12. The shelf life for F12 and M12 was found to be 10 y 52 d and 10 y 70 d respectively which were determined by the zero-order kinetic equation.Conclusion: A more or less similar surface morphology, particle size, drug content and percent of drug release before and after stability study confirmed the stability of F12 and M12 microspheres after storage for 6 mo and prove the efficacy of the microspheres in the site-specific delivery of drugs in Parkinson’s disease.

Delivery of drug through topical route, delivers most convenient and novel approach. The Skin can offer several advantages as a route of drug administration although its barrier nature makes it difficult for most drugs to penetrate in to and permeate through it. During the past decades there has been a lot of interest in lipid vesicles as a tool to improve topical drug delivery. Vesicular system such as liposomes, niosomes, ethosomes and elastic deformable vesicles provide an alternative for improved skin drug delivery. In fact vesicles can act as drug carriers controlling drug release. The Research findings were intended to develop sustained release of aceclofenac niosomes formulations in order to reduce gastrointestinal disturbances and to provide better effect when applied topically. Niosomes of aceclofenac was prepared by modified ether injection method using different ratio of surfactants (Tween 20, 40, 60 & 80) with cholesterol and drug. The developed formulations were optimized based on the high entrapment efficiency and in-vitro release studies. Optimized batch was selected and made in to topical niosomal gel using gelling agents like carbopol and sodium carboxy methyl cellulose. Formulation were evaluated for various parameters like vesicle shape, vesicle size, entrapment efficiency, drug content, compatibility studies, in-vitro release studies and stability studies. Ether injection method was found to be most satisfactory in terms of niosome particle size, drug entrapment efficiency was found to be 88.68 ±0.64 % and in-vitro release studies showed 40% of sustain drug release at the end of 8 hrs of study when compared with marketed formulation. Hence, the formulated niosomal topical gel was found to be a better alternative when compared to the marketed formulation in terms of better efficacy, bioavailability and permeation.

ABSTRACT   In recent years, treatment of infectious disease through Novel Drug delivery system (NDDS) has undergone a revolutionary shift. Niosomes are a Novel Drug Delivery system which has potential application to treat infectious disease topically. Niosomes are non-ionic surfactant vesicles, in which medication is encapsulated in a vesicle for controlled drug release. Ketoconazole niosomes were prepared by using Cholesterol, Span 60/ Span 40 as surfactants, chloroform, and diethyl ether using rotary vacuum evaporator method. Formulation was then evaluated for particle size, drug content, entrapment efficiency, and in-vitro drug release studies. The Entrapment efficiency and drug content were calculated at 225nm using UV spectrophotometer. The drug content was found to be 70.37% for Span 40 and 72.81% for Span 60.The percentage of drug entrapment in niosomes was 60.3 % for Span 40 and 62.21 % for Span 60. FT-IR studies for niosomes containing Span 40 shows -CH stretching (Aliphatic) at 2891 cm-1and2925 cm-1 for niosomes containing Span 60. Ketoconazole niosomal gel was prepared using Carbopol 940, glycerol, Triethanolamine and distilled water. Evaluation of niosomal gel was determined by Physical appearance, pH, viscosity, drug content, entrapment efficiency and In-vitro diffusion studies.The percentage of the drug release from the niosomal gel was found to be 40.78 % for Span 40 and 33.75% for Span 60 . This delivery system is cost effective and simple to prepare as only the prepared gel of niosomes was introduced in Rotary vacuum evaporator for solvent evaporation.
