Novel herbal drug delivery system opens new vistas for delivery of herbal drugs at right place, at right concentration, for right period of time and also gives scientific angle to verify the standardization of herbal drug. Herbal Transdermal patches can develop valuable assessment and drug safety by additional site specific the way and temporal position in the body’s imperative to reduce the number and size of doses required to achieve the objective of systemic medication during topical application to the intact skin surface. Rheumatoid Arthritis (RA) is a chronic, progressive autoimmune disease of unknown cause. It is characterized by persistent inflammation that primarily affects the peripheral joints. In the present study, herbal transdermal patch was developed by using ethanolic extract of leaves of Cardiospermum halicacabum and rhizomes of Drynaria quercifolia that had already been widely used for the treatment of arthritis in conventional dosage forms. Evaluation of the developed patch for the effectiveness against RA was done by in vitro methods in terms of inhibition of albumin denaturation, measurement of Interleukin-6 cytokines by Enzyme-Linked Immuno Assay (ELISA). IC-50 value was determined from albumin denaturation inhibition assay. The herbal patch significantly and dosedependently inhibited Interleukin–6 cytokines. The present study revealed that the formulated polyherbal Transdermal patch will be the better drug of choice for the treatment of Rheumatoid Arthritis as compared to the conventional dosage forms.

Recent Advances in Topical Nanotechnological Strategies for Treatment of Alopecia

Alopecia can be characterized as a hair-related disorder leading to decreased hair growth, especially on the scalp. It has affected approximately 2% of the world population. The hair loss may emerge due to genetic or environmental factors like stress, infectious agents, tensile forces or medications. The pathogenetic pathway of induction of alopecia comprises of different factors, but exploitation of hair follicle immune privilege system (HFIP) is the most prominent one. Alopecia can be classified into two types: scarring alopecia or non-scarring alopecia. Although, many conventional dosage forms have been formulated against alopecia, but they have been associated with different adverse effects such as weight gain, palpitations, itching etc. In order to overcome the adverse effects associated with conventional dosage forms, the topical nano-formulations have been used for the treatment of dermatological disorders. Nano-formulations are known to increase the contact time of drug with the target site, thereby, achieving sustained and controlled release of the drug leading to enhanced therapeutic compliance. This review provides an in-depth study of developed nanocarriers like liposomes, nano-emulsions, ethosomes, solid lipid nanoparticles (SLNs), nanostructured lipid carriers (NLCs) along with their composition, method of preparation, results obtained after formulation, suitable use and along with their potential use in treatment of different forms of alopecia.

Design and Characterization of Orlistat Bilayered controlled release Tablets

Drug delivery in conventional dosage forms often suffers from the drawbacks of repeated drug administration and large fluctuations in blood drug levels. Controlled drug delivery systems are a convenient way of controlling the dosing frequency responsible for rapid absorption and distribution of drug in conventional dosage forms, and are dependent upon two intrinsic properties of the drug, namely, elimination half-life (t1/2) and therapeutic index (TI). The goal is to give a drug at a sufficient rate, frequency and dose so that the ratio Cmax/Cmin in plasma at steady state is always maintained at effective concentrations during the course of therapy, reducing side effects or improving physicochemical and biopharmaceutical properties. The use of polymers provides the potential to control drug delivery both temporally and spatially. The objective of the present investigation was to develop bilayered tablets of orlistat to achieve controlled release and immediate release. The process is predetermined in such a way to release the drug at an IR and CR by using different polymers. Half life of orlistat is 1-2 hrs, as it has been released immediately. This paper mainly focuses on designing the process to release the drug in a controlled manner by using different polymers like sodium alginate, ethyl cellulose, HPMC.

Topical Dosage Form & Delivery System for Pigmentation Control: A Review

Hyperpigmentation is one of the most commonly seen skin disorders which is not a concerning health issues but it may affect the psychological aspect of a person. Hyperpigmentation is caused by the presence of excess melanin, which is the brown pigment of the skin. Products that aimed to reduce the pigmentations act by inhibiting the tyrosinase enzyme, which is the rate-limiting enzyme in the synthesis of melanin. There are many products that are currently available in the market that aims to reduce pigmentation of the skin. These products are conventionally formulated into different dosage forms such as cream, lotion and emulgel, which gains popularity due to its convenience on application. However, due to the drawbacks that these dosage forms possess such as poor stability and absorption, new formulations are presented which incorporate novel drug delivery system into the conventional dosage forms. These novel drug delivery systems are, inter alia, liposome, niosomes and microsphere. They carry benefits of controlled drug delivery, enhanced skin penetration and reduce drug toxicity as compared to the conventional dosage form, which resulted in the increase in marketed product diving into this pathway. This present article will discuss the various dosage forms, drug delivery system, its advantages, disadvantages and marketed product for pigmentation control.

Most promising solid dispersion technique of oral dispersible tablet

Background The most common problem about conventional dosage form is dysphagia (difficulty in swallowing). So, we design a new approach in a conventional dosage form which is oral dispersible tablet. Oral dispersible tablet is also called as mouth dissolving tablet, fast dissolving tablet, or oral disintegrating tablet. Oral dispersible tablet has advantage as it quickly disintegrates into saliva when it is put on the tongue. The faster the drug disintegrates or is dissolved, the faster the absorption and the quicker the therapeutic effect of drug will be attained. Main text This review article focuses on the progress in methods of manufacturing and various latest technologies involved in the development of oral disintegrating tablet. The solid dispersion technique is one of the novel techniques to manufacturing the oral dispersible tablet. Solid dispersion is basically a drug polymer two component system. Conclusion This review article focuses on advantages, disadvantages, materials used as carrier for solid dispersions, methods of preparation of solid dispersion, classification of solid dispersion, promising drugs that can be incorporated into oral disintegrating tablet by solid dispersion techniques, and recent research in solid dispersion technique using polymers as carriers.

Primordial science and pioneering approaches of guggul for chronic ailments – A modernized review

An oleo gum resin guggulu is a product which obtained as a result of gummosis from the bark of Commiphora wightii (Arnott) Bhandari [syn. Commiphoramukul (Hook. Ex Stocks) Family, Burseraceae]. It has been known for its immense applicability in the Ayurveda since time immemorial for the treatment of variety of disorders such as inflammation, gout, rheumatism, impotence, leprosy, obesity, and disorders of lipids metabolism. It is a mixture of phytoconstituents like terpenoids, steroids, flavonoids, guggultetrols, lignans, sugars, and amino acids. This review is an effort to compile all the information available on all of its chemical constituents which are responsible for its therapeutic potential, limitation of guggul extracts and the necessity of novel principles for gum guggul. Nowadays, Guggul is available as the marketed formulation for curing numerous clinical conditions and is accessible in combination with various other ingredients. Though conventional dosage form shows the dominance as patient compliance and easy availability, yet it has found to pose the problems like dose fluctuation, peak-valley effect, non-adjustment of the administered drug, invasiveness etc. Guggul lacks its desired effect due to its low bioavailability and water solubility. This makes it a partial or a deficient therapy for remedy of many signs and symptoms. Novel drug delivery system (NDDS), a new approach and has excluded many of drawbacks exhibited by conventional dosage forms. Some of the novel dosage forms of guggul has been formed like nanoparticles, nanovesicles, gugglusomes and proniosomal gel. But still, the novel formulations for guggul has its less outspread in the market. Guggul can be executed as a profitable drug using NDDS. There is a need to highlight the unidentified and unexplained facts about guggul so as to make it more efficacious and effective in terms of bioavailability and aqueous insolubility.
