Delivery across skin is striking due to its easy convenience. However, drug delivery across skin is still a confront in biomedical sciences. Over the past few decades, various successful narrative devices and techniques have emerged to optimize drug delivery across skin whose barricading behaviour constricts entry of most of the therapeutic agents. Ethosomes are non-invasive delivery transporter that enables drugs to reach the deep skin layers and/or the systemic circulation. Although ethosomal systems are theoretically sophisticated, they are characterized by simplicity in their preparation, efficacy and safety. A combination that can highly inflate their application. Ethosomes are soft, malleable vesicles adapted for enhanced delivery of active agents. This article reviews work carried out method of preparation, application and characterization of ethosomal systems. Because of their exceptional structure, ethosomes are able to encapsulate and deliver through the skin highly lipophilic molecules such as testosterone, cannabinoids and minoxidil as well as cationic drugs such as trihexyphenidil and propranolol. Results obtained in a double-blind two-armed randomized clinical study showed that treatment with the ethosomal acyclovir formulation appreciably improved all the evaluated parameters. In further work, the ethosomal expertise was broadened to introduce agents into cultured cells and microorganisms. Enhanced delivery of bioactive molecules through the skin and cellular membranes by means of an ethosomal transporter opens numerous confronts and prospects for the research and future development of novel improved therapies.

The present study deals with the formulation and evaluation of transdermalpatches of meloxicam towards enhance its permeation through the skin and maintain the plasma levelconcentration. Transdermal patches were prepared by using polymers like Chitosan, HPMC 15cps and EC 20cpsat various concentrations by solvent casting technique employing dibutyl phthalate as plasticizer and isopropylmyristate as permeation enhancer. The transdermal patches were evaluated for their physico-chemical properties and in-vitro drug release. The transdermal patches were found to be transparent and smooth in texture. Amongthe formulations studied, at the end of 12th hour, the minimum and maximum in-vitro drug release was observedfor the formulations F12 and F4i.e. 80.012 ± 2.012 % and 98.365±3.012%. The mechanism of drugrelease was found to be Non-Fickian diffusion controlled. FT-IR studies revealed theintegrity of the drug in theformulations. Keywords: Transdermal Patches, Meloxicam, Chitosan, HPMC 15cps, EC 20 cps, in-vitro diffusion studies.
Herbal medicine is a complementary therapy that some people with cancer use to ease cancer symptoms and relieve treatment side effects. Mesothelioma patients should discuss herbal medicine with their doctor to avoid drug interactions and negative treatment consequences. Is Herbal Medicine Safe for Cancer Patients? Herbs may seem harmless, but sometimes they can interfere with cancer treatment. For example, some herbs can prevent chemotherapy and radiation therapy from killing cancer cells. Certain herbs enhance the effect of chemotherapy in a toxic way that leads to unwanted side effects. Doctors recommend patients avoid herbs during treatment. It won’t be safe until research can identify which herbs are safe to combine with cancer treatment. Clinical trials that combine herbal medicine with cancer therapies are relatively new to the United States. China has performed such trials since the early 1900s. Cancer doctors rely on clinical trials to recommend treatments that are proven effective.
The drug ABT-335 (Fenofibricacid ) choline fenofibrate found to be useful in the treatment of dyslipidemia as compare with other fibrate. So the present investigation to developed mini-tablets to overcome the dose dumping problem by regular shape, uniformity, smooth surface excellent size and encapsulated in capsule to improve the efficacy and bioavailability of the drug. Different formulations were developed by utilizingcontrolling of the release rate and gel forming polymers like microcrystalline cellulose, hypromellose by dry granulation technique. Among all formulation SRM-3 having the drug release for longer period of time as compare to other formulation. SRM-3 was found to be stable during stability study for one month. Keywords: ABT-335 (Fenofibric acid) choline fenofibrate, like microcrystalline cellulose, hypromellose, sustained release matrix tablet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
