BACKGROUND Oral cavity has been proposed as an important reservoir of H.pylori, being implicated in bacterial transmission through oral-oral route. However, some investigators believe that the newborn acquires H.pylori from mother through vaginal delivery. In this study, oral and vaginal yeasts were examined for the intracellular occurrence of H.pylori and their possible role in bacterial trans...

Till recent, injections remained the most common means for administering therapeutic proteins and peptides because of their poor oral bioavailability. However, oral route would be preferred to any other route because of its high levels of patient acceptance and long term compliance, which increases the therapeutic value of the drug. Designing and formulating a polypeptide drug delivery through ...

Osmotic drug delivery mechanism is well known in the field of oral controlled release systems. The release of drug from the osmotic drug delivery devices is based on the phenomenon of osmosis. An useful technology developed for osmotic delivery of drug is asymmetric membrane capsule (AMC), which is an economic and effective drug delivery device as compared to other existing technique of osmotic...

Copyright © 2012 Frederick Furness Publishing 16 In this paper, Thomas Dries, PhD, Market Development Manager Europe, Healthcare & Packaging, Honeywell Specialty Materials, considers the challenges facing the pharmaceutical industry in implementing a blister packaging strategy that: protects advanced solid oral drug delivery systems from physical or chemical degradation; creates market advantag...

Intestinal permeation enhancers (PEs) are one of the most widely tested strategies to improve oral delivery of therapeutic peptides. This article assesses the intestinal permeation enhancement action of over 250 PEs that have been tested in intestinal delivery models. In depth analysis of pre-clinical data is presented for PEs as components of proprietary delivery systems that have progressed t...

OBJECTIVE To evaluate the outcome of pregnancy in women with mechanical heart valve prostheses in relation to the anticoagulant treatment used in the first trimester and the incidence of thrombotic and bleeding complications. METHODS 92 pregnancies in 59 women were followed between 1986 and 1997. In 31 pregnancies, oral anticoagulants were discontinued when pregnancy was diagnosed and subcuta...

Transporters play important roles in tissue distribution and urinary- and biliary-excretion of drugs and transporter molecules involved in those processes have been elucidated well. Furthermore, an involvement of efflux transporters such as P-glycoproteins, multidrug resistance associated protein 2, and breast cancer resistance protein as the intestinal absorption barrier and/or intestinal lumi...

Oral controlled drug delivery has gathered tremendous attention over the years due to its many advantages over conventional dosage forms. Polymer-based matrices have become an integral part of the pharmaceutical industry. Hydrophilic matrices are capable of controlling the release of drug over an extended period of time. Hydrophilic polymers, especially the hydrophilic derivatives of cellulose ...
