Oral delivery of curcumin (CUR) has limited effectiveness due to CUR’s poor systemic bioavailability caused by its first-pass metabolism and low solubility. Buccal delivery of CUR nanoparticles can address the poor bioavailability issue by virtue of avoidance of first-pass metabolism and solubility enhancement afforded by CUR nanoparticles. Buccal film delivery of drug nanoparticles, nevertheless, has been limited to low drug payload. Herein, we evaluated the feasibilities of three mucoadhesive polysaccharides, i.e., hydroxypropyl methylcellulose (HPMC), starch, and hydroxypropyl starch as buccal films of amorphous CUR–chitosan nanoplex at high CUR payload. Both HPMC and starch films could accommodate high CUR payload without adverse effects on the films’ characteristics. Starch films exhibited far superior CUR release profiles at high CUR payload as the faster disintegration time of starch films lowered the precipitation propensity of the highly supersaturated CUR concentration generated by the nanoplex. Compared to unmodified starch, hydroxypropyl starch films exhibited superior CUR release, with sustained release of nearly 100% of the CUR payload in 4 h. Hydroxypropyl starch films also exhibited good payload uniformity, minimal weight/thickness variations, high folding endurance, and good long-term storage stability. The present results established hydroxypropyl starch as the suitable mucoadhesive polysaccharide for high-payload buccal film applications.

Background and Objective: Upon oral administration domeperidone is rapidly absorbed, but subjected to the first pass effect which lowers systemic bioavailability to 15%. Mucoadhesive tablet can remain attached to buccal mucosa and becomes capable of bypassing hepatic first-pass metabolism to improve absorption directly into systemic circulation. The present research work was carried with an aim to develop, evaluate and optimize mucoadhesive tablet containing domperidone (DOME) for buccal delivery using different bio-adhesive polymeric combinations. </P><P> Methods: The buccal tablets were formulated by wet granulation method using isopropyl alcohol. The preliminary formulations were prepared using combinations of HPMC K4, HPMC K15, HPMC K100, HPMC E5 as mucoadhesive polymers. 32 full factorial design was applied to determine the effect of independent variables like concentration of mucoadhesive polymers (HPMC K15 and HPMC K100) over dependent variables like mucoadhesive properties (swelling index, bioadhesive strength and in vitro drug release). The prepared mucoadhesive tablets were evaluated for their tablet properties and mucoadhesive properties. The interactions between drug and polymers were studied by Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC). </P><P> Results: All formulations of factorial design showed satisfactory physicochemical, mechanical and bioadhesive characteristics. The formulation F9 exhibited maximum cumulative drug release, mucoadhesive strength and swelling index. Conclusion: The developed buccal tablet of domperidone might prove alternative to bypass the hepatic first pass metabolism and to avoid degradation which in turn may result in reducing the frequency of administration. Thus, mucoadhesive tablet of domeperidone may become viable alternative overcoming the side effects; achieving greater therapeutic effectiveness and improving the patient compliance.

Oral bioavailability of drugs is mainly limited due to the poor aqueous solubility, enhanced chemical degradation, reduced permeation and/or first pass metabolism. Various novel delivery systems are developed for improved oral bioavailability of these drugs such as modified orals, buccal, transdermal and osmotic delivery systems. Colloidal carrier systems such as nanoparticles, lipid nanoparticles, nanoemulsions, microspheres, liposomes, resealed erythrocytes and transfersomes were also developed to enhance the oral delivery. Among these, solid lipid nanocarriers (SLNs) also gain much attention on the enhancement of oral bioavailability. SLNs are submicron sized nanoparticles and composed of solid lipid, surfactants and cosurfactants. The enhanced oral bioavailability of poorly soluble drugs from SLNs might be due to the reduced particle size, bypassed presystemic metabolism, and enhanced gastric mucosa permeability. Vast literature is available for the advantages, limitations, preparation methods, evaluation parameters and application of SLNs in different routes. This review mainly focused on list of drugs developed as SLNs and considered as an alternative approach to enhance the oral bioavailability based on pharmacokinetic as well as pharmacodyanmic parameters was discussed. Keywords: Oral bioavailability, solubility, first-pass metabolism, solid lipid nanoparticles, pharmacokinetics, pharmacodynamics.

Back ground: Nifedipine is a calcium channel blocker and is used in treatment of angina of angina pectoris and hypertension. Nifedipine readily and almost completely absorbed from GIT, but undergoes first pass metabolism, resulting in low oral bioavailability is about 50%. Aim: The aim of the present study was to prepare and evaluate the microspheres of nifedipine with a goal of improving the bioavailability and giving a prolonged release of drug. Method: Emulsification (o/w) solvent evaporation method was employed in the preparation of nifedipine microparticles using ethyl cellulose and combination of ethyl cellulose and hydroxypropyl methylcellulose as the polymers. Results: FT-IR spectra of physical mixture showed no significant shifting of the peaks therefore it reveals that the drug is compatible with the polymer used. The percentage yield obtained in all the formulations was good and in the range of 59.25-94.44%. Among all the formulations, formulation with combination of ethyl cellulose and hydroxypropyl methylcellulose polymers M9 showed high amount of drug release i.e. (91.23%) in 12hrs. Drug release from microspheres with small mean particle size was faster than those with large mesh particle size and followed Higuchi model of kinetics. Conclusion: The obtained results could be used as essence to develop microspheres, which bypasses first-pass metabolism and results in the improvement of bioavailability. Hence, the present study has been a satisfactory attempt to formulate microspheres of nifedipine, with a view of improving its oral bioavailability and giving a prolonged release of drug. Keywords: Microspheres, nifedipine, hydroxypropyl methylcellulose E5, ethyl cellulose.

Abstract The oral route of drug administration is the most common and convenient route for dosing statin drugs, and, in fact, most medications, because of ease of drug delivery, patient compliance, and cost-effectiveness. However, the oral administration of statin drugs has disadvantages such as hepatic first-pass metabolism and degradation within the gastrointestinal tract that limit their overall bioavailability. This review introduces several diverse non-oral delivery methods for the administration of statins. These alternative delivery systems and routes of administration are varied and are capable of improving the bioavailability and therapeutic efficacy of statin drugs.
