The immune system in the gastrointestinal tract plays a crucial role in the control of infection, as it constitutes the first line of defense against mucosal pathogens. The attractive features of oral immunization have led to the exploration of a variety of oral delivery systems. However, none of these oral delivery systems have been applied to existing commercial vaccines. To overcome this, a ...

Nutraceutical is a food or à food ingredient that provides medical and health benefits. Polyphenols play an important role in the maintenance of health and prevention of diseases. Among polyphenols, the most widely used substance Curcumin. Curcumin derived from the herbal remedy and dietary spice turmeric. It possesses wide range of beneficial properties includes anti-inflammatory, anti-oxidant...

Absorption of drugs through the oral cavity was noted as early as 1847 and systemic studies of oral cavity absorption were first reported in 1935 [1]. Since then, substantial effort has been focused on drug absorption from a drug delivery system in a particular region of the oral cavity [2-5]. As a site for drug delivery, the oral cavity offers many advantages over other routes of drug administ...

The oral route for drug delivery is regarded as the optimal route for achieving therapeutic benefits owing to increased patient compliance. Despite phenomenal advances in injectable, transdermal, nasal and other routes of administration, the reality is that oral drug delivery remains well ahead of the pack as the preferred delivery route. Nanocarriers can overcome the major challenges associate...

A variety of approaches have been investigated to address the problems associated with oral insulin delivery, but the bioavailability of oral insulin is still low. Insulin is rapidly degraded by the enzymes in the GI tract and is not transported across the epithelial barrier easily. The oral insulin formulation developed in this work makes use of complexation hydrogels for oral delivery of insu...

Diabetes mellitus (diabetes) is suffered by more than 180 million people and is responsible for approximately 2.9 million deaths each year. This mortality rate is expected to increase by 50 % in the next decade. Due to the inconvenience of the traditional treatment of diabetes by subcutaneous administration of insulin injection, various attempts are made in the production, purification, formula...

To answer challenge of targeted and controlled drug release in oral delivery various materials were studied by different methods. In the present paper, controlled metal based drug (Pd(II) complex) release manner of β‑Lactoglobulin (β-LG) nanoparticles was investigated using mathematical drug release model in order to design and production of a new oral drug delivery system for gastrointestinal ...
