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.

A drug delivery system is a system in which a drug is released from a pharmaceutical dosage form to achieve the desired pharmacological effect. The system consists of conventional and new drug delivery systems. In the new drug delivery system, polymers are used as a matrix. The aim of this article is to find out and understand the formulation and evaluation of natural ingredients that have anticancer activity with different dosage forms and the basis for developing these dosages. Journal searches in this review came from primary data sources on the internet. Journal searches were carried out using a search engine such as Google Scholar, PubMed, and ScienceDirect. In recent years, natural products, such as extract, fraction, and isolate, are getting attention to help treat cancer. Because of their low solubility and bioavailability, the effectiveness tends to be lower than synthetic drugs. Therefore, a dosage form with a new drug delivery system was made to overcome the problem. The dosage forms commonly made are patch, suspension, powder, and emulsion with a new drug delivery system. To ensure the product that has been made met the requirements, they need to be evaluated with various methods like In vitro Study, morphology study, particle size study, and others. Cancer treatment using the natural product can be delivered through several dosage forms like patch, suspension, powder, and emulsion, with specific formulation and manufacturing methods based on several considerations such as natural ingredients properties, dosage form selection, excipient properties, and the purpose of the formulation. Dosage forms that has been made are then evaluated using several evaluation methods.

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.

Novel Drug

There are many problems with the conventional dosage form of various drugs and one of them is dosing frequency in which patients have to take the drug again and again throughout the day which is very difficult mainly for the elder patient. So, to overcome this problem the approach of a novel drug delivery system (NDDS) is used to replace the conventional drug delivery system. NDDS mainly deals with sustained release of drugs which is effective to reduce the dosing frequency. Niosome is one of the best approaches of a novel drug delivery system, in which the drug in solution form is enclosed in vesicle which is made up of non-ionic surfactants. In the case of liposome which is another part of NDDS vesicles is made up of phospholipids. Niosome formulation is a powerful tool to resolve the issue of insolubility and the low bioavailability of drugs. This paper overviews the various methods of preparation of Niosome along with its pharmaceutical applications.

In case of intra-vaginal route of drug administration the dosage form is applied vaginally for the convenient release of the dosage form and for better therapeutic action of the medicament, it is usually used in HIV patients. many conditions that affect the  female reproductive tract, such as , sexually transmitted diseases, fungal & bacterial infections,  cancer and various pathogens such as virus (human immunodeficiency virus, HIV), bacteria (Gardnerella vaginalis), fungi (Candida spp.) or parasites (Trichomonas vaginalis). Systemically active drugs (contraceptive steroids) as well as locally active drugs (metronidazole Zidovudine, Lamivudine) can be effectively delivered for an extended period of time by the help of intra-vaginal  controlled release system. Continuous infusion of drugs through vaginal mucosa results in the reduced possibilities of Hepatic- gastrointestinal first-pass metabolism, gastric impatience of drugs and vacillation of dosing interval. Current study focus on the, use of various polymers which are used in hydrogels, these polymers provide bioadhesive property to the vaginal formulations, so that the vaginal formulation remains on vaginal tissues for 3- 4 days. Currently available vaginal dosage forms have several limitations, such as leakage and messiness necessitating the need to develop novel drug delivery systems.

Recently, most widely using conventional dosage form such as tablet, capsules, and injections but due to some case we are preferable to choose transdermal drug delivery system (TDDS) because conventional oral dosage form undergo first pass metabolism. In TDDS, skin is the effective medium for the penetration of drug into systemic circulation. This system required very low dose for the effective result or action. One of the major disadvantages of TDDS is penetration rate is very low through the stratum corneum. Nowadays, different types of skin penetration enhancement techniques are used for increasing the penetration. These types of techniques can be also increase the bioavailability. The patients have more preferable to choose this type of drug delivery system because it has more advantages than conventional dosage form. This article is discuses about the anatomy and physiology of skin and its drug penetration capacity, polymers used in transdermal drug delivery and different types of TDDS.
