The successful delivery of drugs across the oral mucosa represents a continuing challenge, as well as a great opportunity. Oral transmucosal delivery, especially buccal and sublingual delivery, has progressed far beyond the use of traditional dosage forms with novel approaches emerging continuously. This review highlights the physiological challenges as well as the advances and opportunities fo...

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...

introduction: oral delivery is the most favorable route for insulin administration. the aim of this study was to generate new chitosan coated insulin nanoliposomes and then to assess the physiological efficacy of these nanoliposomes after oral administration in diabetic rabbits. methods: nanoliposomes with negative surface charge encapsulating insulin were prepared by reverse phase evaporation ...

introduction: the purpose of this study was to compare the efficacy and side effects of two different misoprostol regimens for second-trimester pregnancy termination. methods: 60 consenting women who were at 14 to 28 weeks of gestation with indications for pregnancy termination were randomly assigned to two equal groups to receive either vaginal or oral misoprostol. the dosing regimen was 400µg...

INTRODUCTION Many therapeutics are limited to parenteral administration. Oral administration is a desirable alternative because of the convenience and increased compliance by patients, especially for chronic diseases that require frequent administration. Polymeric nanoparticles (NPs) are one technology being developed to enable clinically feasible oral delivery. AREAS COVERED This review disc...

Oral delivery is the preferred route of drug administration due to patient compliance and convenience. Despite this, nanomedicines have so far primarily been developed for parenteral route. Inorganic nanoparticles hold great promise as theranostics oral delivery. This gaining importance especially local treatment gastrointestinal (GI) diseases. However, successful inorganic challenged by comple...

BACKGROUND Over the past decade there has been increasing interest in the use of lactic acid bacteria as mucosal delivery vehicles for vaccine antigens, microbicides and therapeutics. We investigated the mechanism by which a mucosal vaccine based in recombinant lactic acid bacteria breaks the immunological tolerance of the gut in order to elicit a protective immune response. METHODOLOGY/PRINC...

Introduction Inhalation as a drug delivery route has been in clinical practice for more than 50 years, with small molecules for the treatment of asthma/COPD capturing the ma jority market share of inhalation products. Since that time, protein therapeutics or biotherapeutics have emerged as a significant class of drugs in clinical development and on the market. Delivery of biotherapeutics direct...
