Abstract

Oral route of administration is the most accepted delivery route due to easy painless administration. Oral route is more suitable for chronic therapy and sustained delivery. In recent years oral approach has been used for delivery of various anticancer drugs like Zytiga, Capecitabine, Topotecan. The number of oral administrations of anti-tumour agents has been increased with respect to all other available cancer therapies. Preferable for patients as it reduces the efforts of regular visit to clinic or venepuncture. The most limiting factor for oral delivery is gastrointestinal barrier where epithelial membrane leads to poor permeability of drug and chemicals and enzymes in gastrointestinal tract causes degradation of bioactive compounds. In addition to this pH varies drastically across the GI tract, ranges from 1 to 2 pH in stomach reaching 7 to 8 in colon and rectum. To conquer this limitations nanocarriers are been developed to encapsulate and protect the drugs eventually increasing their pharmacokinetics. The most attractive method includes pH responsive soluble coatings, mucoadhesive nanocarriers, enzyme inhibitor and microbial control system. The present review discusses natural products in cancer treatment, obstacles in their oral delivery and nanotechnology approach to deal with the challenges.
