Traditional remedies and preparation used for the treatment of skin, or the folk preparations used for healing skin diseases are known to be as Cosmeceuticals and cosmetics. The desire of gook looking and to be beautiful gave a huge market for the cosmetics. This is not a new tradition for human to look good; it has been a long ancient follow through for both the sexes to be presentable by beauty. For now, the desire of both the sexes to look younger than there age, to be fare and charming have directly increased the demand of herbal cosmetics as well as of the Cosmeceuticals in the market. The herbal formulations have been the first choice of the customers. For the reason of being less side effective and thought to be more potent than the synthetic formulations. There has been a long use of turmeric and sandalwood to be applied of face for fairness and freshness. As like many other herbs are used in daily life to be called as...

Chromolaena odorata or siam weed is regarded as one of the most harmful weeds present on earth. Many efforts are being made for the control of this weed. But, none of them have provided any significant success. It has been utilized in the traditional medicinal systems for its curative properties for centuries. Some of the current studies have revealed its medicinal properties which have lead to an enhanced image of this plant as a medicinal herb. It showed anti-inflammatory, anti pyretic, analgesic, antimicrobial, cytotoxic and many other relevant medicinal properties in an appreciable...

Oral route is the easiest and most convenient route of drug administration, being non invasive and cost effective, thereby leading worldwide drug delivery market. But major problem encountered in oral formulations (as estimated more than 50 % of oral formulations are found to be poorly aqueous soluble), is low bioavailability, giving rise to further problems like, high inter and intra subject variability, lack of dose uniformity and finally leading to therapeutic failure. The challenging task is to increase the bioavailability of drugs. Number of technological strategies are investigated and reported in literature for improving bioavailability like solid dispersions, cyclodextrins, micronization etc. But Self-microemulsifying Drug Delivery System (SMEDDS) have gained exposure for their ability to increase solubility and bioavailability of poorly aqueous soluble drugs with reduction in dose and also drugs are protected from hostile environment in gut. SMEDDS are isotropic mixture of oil, surfactant, drug and sometimes containing co-surfactant and administered orally which on mild agitation with GI fluids forms o/w microemulsion. This review gives complete overview of SMEDDS...

The buccal mucosa has been investigated for local drug therapy and the systemic delivery of therapeutic peptides and other drugs that are subjected to first-pass metabolism or are unstable within the rest of the gastrointestinal tract. The mucosa of the oral cavity presents a formidable barrier to drug penetration, and one method of optimizing drug delivery is by the use of adhesive dosage forms and the mucosa has a rich blood supply and it is relatively permeable. The buccal mucosa is very suitable for a bioadhesion system because of a smooth and relatively immobile surface and accessibility. Therefore, drugs with a short biological half life, requiring a sustained released effect and exhibiting poor permeability, sensitivity to enzymatic degradation, or poor solubility may be good candidates to deliver via the oral cavity. To overcome the drawbacks of tablets flexible patches for use in the mouth have been developed. Erodible and non-erodible adhesive films have been used as bioadhesive films. These adhesive patches for oral mucosal delivery can be used to...

Solid dispersions have been employed to enhance the dissolution rates of poorly water-soluble drugs. Many approaches have been investigated for the preparation of solid dispersions. This paper reports the various solubility enhancement strategies in solid dispersion. The approaches described are fusion (melting), solvent evaporation, lyophilization (freeze drying), melt agglomeration process, extruding method, spray drying technology, use of surfactant, electro static spinning method and super critical fluid technology. This paper also highlights the potential applications and limitations of these approaches in solid...
