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.

Nasal route had shown better systemic bioavailability due to its large surface area, porous endothelial membrane, high total blood flow, and avoidance of first-pass metabolism. Timolol maleate is a beta blocker used primarily in the treatment of hypertension. Drug undergoes extensive hepatic first-pass metabolism (80%). The drug has half-life of 4 hrs. Oral bioavailability of timolol maleate is 61%. The aim of the present study was to optimize controlled releasein situnasal delivery for timolol maleate. HPMC and Poloxamer 407 were selected as polymer in formulation of thermoreversiblein situnasal gel. Optimization was carried out using 32factorial design. It was observed that formulations f1 and f4 revealed the highest % drug release, that is, 93.57% and 91.66%, respectively. Factorial design study indicated that the drug release and viscosity were most significant dependent factors.Ex vivodiffusion study through nasal mucosa indicated 67.26 ± 2.10% and 61.07 ± 2.49% drug release for f1 and f4 formulations. f1 was the optimized batch. This batch thus can act as a potential nasal delivery with enhanced bioavailability for the drug.

Mucoadhesive drug release system is a preferably unidirectional release system where mucosal epithelial exterior is enclosed by the mucus deposit that interacts with the bio-adhesive drug delivery system and swelling time of the buccal dosage form which is amplified by mucin molecules at the location of administration. Eplerenone is an Anti-hypertensive drug that undergoes hepatic first pass metabolism and shows 69% of bioavailability. In order to bypass the hepatic first pass metabolism the drug is designed to be delivered through buccal cavity to avoid the first pass metabolism. Eplerenone buccal tablets were formulated by using direct compression method with different polymers like HPMC K 100M, Carbopol 934P, Carbopol 974P, Xantham Gum, Eudragit L100 and NaCMC in various concentrations and compositions. Incompatibility complications were not observed from the FTIR spectrums. The formulated and prepared buccal solid dosage forms were evaluated for pre-compressions and post- compression parameters such as hardness, weight variation, thickness, friability, surface pH, swelling index, in-vitro dissolution studies, drug content uniformity, mucoadhesion strength and mucoadhesion time. Evaluation results of formulation F12 are proven to be the optimal formulation showing highest mucoadhesion time, mucoadhesion strength and in-vitro drug release for prolonged period of time about 8 hours. Eplerenone is best delivered through buccal drug delivery system to enhance its oral bioavailability and bypass the hepatic first pass metabolism.

The objective of this study was to develop mucoadhesive tablets of Simvastatin using natural polymers. Simvastatin has short biological half-life and high first pass metabolism hence which was designed to increase the gastric residence time which prolong the drug release. The tablets were prepared by wet granulation technique using Carbopol-934, guar gum, xanthine gum and chitosin as polymers. Formulations were evaluated for different parameters like hardness, friability, uniformity of weight, swelling characteristics, in vitro dissolution and kinetic studies. The dissolution was carried out for 12 hours in which the formulation with guar gum has shown highest dissolution release profile (F9). Thus the present study concludes that mucoadhesive tablets of simvastatin can be a good way to pass the extensive hepatic first pass metabolism and to improve the bioavailability of simvastatin.DOI: http://dx.doi.org/10.3329/icpj.v2i9.16077 International Current Pharmaceutical Journal, August 2013, 2(9): 152-155

Objective: Olmesartan belongs to a class of angiotensin II receptor blockers. It is used in the treatment of hypertension. However, it undergoes extensive hepatic first-pass metabolism, resulting in low oral bioavailability is about 26%. The aim of this study was to prepare and evaluate the mucoadhesive buccal tablets of olmesartan with a goal to increase the bioavailability and improve the patient compliance.Methods: Mucoadhesive buccal tablets were prepared by a direct compression technique using mucoadhesive polymers such as hydroxypropyl methylcellulose (HPMC K4M), sodium carboxymethylcellulose (SCMC), and Carbopol 934P. The tablets were evaluated for weight variation, thickness, hardness, friability, surface pH, swelling index, drug content uniformity, in vitro drug release, ex vivo mucoadhesive strength, ex vivo mucoadhesive time, and ex vivo permeation studies. The release kinetics was calculated to determine the drug release mechanism. Results: The physicochemical properties of all the formulations were shown to be within the limits. The optimized buccal tablets F2, F7, and F11 showed satisfactory drug release rates with the diffusion controlled mechanism. Optimized buccal tablets developed for olmesartan possess reasonable mucoadhesive strength, mucoadhesive time, and surface pH was in an acceptable salivary pH 6.76±0.28–6.89±0.34. The ex vivo permeation studies for optimized tablets were shown satisfactory drug permeation and could meet the target flux 0.991 mg h−1cm−2.Conclusion: The obtained results could be used as a platform to develop the buccal delivery of this drug, which bypasses the first-pass metabolism and results in the improvement of bioavailability. Hence, the present study concludes that the olmesartan could be delivered through the buccal route.

The conventional oral administration of many nutraceuticals exhibits poor oral bioavailability due to the harsh gastric conditions and first-pass metabolism. Oral mucosa has been recognized as a potential site for the delivery of therapeutic compounds. The mucoadhesive formulation can adhere to the mucosal membrane through various interaction mechanisms and enhance the retention and permeability of bioactive compounds. Absorption of bioactive compounds from the mucosa can improve bioavailability, as this route bypasses the hepatic first-pass metabolism and transit through the gastrointestinal tract. The mucosal administration is convenient, simple to access, and reported for increasing the bioactive concentration in plasma. Many mucoadhesive polymers, emulsifiers, thickeners used for the pharmaceutical formulation are accepted in the food sector. Introducing mucoadhesive formulations specific to the nutraceutical sector will be a game-changer as we are still looking for different ways to improve the bioavailability of many bioactive compounds. This article describes the overview of buccal mucosa, the concept of mucoadhesion and related theories, and different techniques of mucoadhesive formulations. Finally, the classification of mucoadhesive polymers and the mucoadhesive systems designed for the effective delivery of bioactive compounds are presented.

Cefixime trihydrate (CT) is a third-generation cephalosporin antibiotic and is used in the management of various infections caused by Gram +ve as well as Gram – ve bacteria. It has a plasma half-life of 3-4 h. It has poor oral bioavailability due to hepatic first pass metabolism. Hence, an attempt was made to develop CT mucoadhesive tablets for buccal delivery to avoid first-pass metabolism and improved oral delivery. CT mucoadhesive tablets developed using HPMC K4M, Na-CMC, guar gum and chitosan as rate controlling polymers and mucoadhesive agent, respectively and compressed by direct compression method. The prepared CT mucoadhesive tablets were evaluated for hardness, weight variation, thickness, friability, drug content uniformity, assay, mucoadhesive strength and in vitro release. From the results, all the evaluated parameters were within the pharmacopoeial limits. The in-vitro dissolution studies indicated that the CTmucoadhesive tablets formulation (F2) showed 99.7±1.4 % of drug release after 8 h and chose as the optimized formulation. The kinetic models suggest that the drug release follows Higuchi’s kinetics and tablets drug release was controlled by a diffusion mechanism.

Objective: The study aimed to prepare and characterize inclusion complexes of tacrolimus with β-cyclodextrin to improve its solubility and to formulate them into sublingual fast disintegrating tablets with a view to bypass the first-pass metabolism. Methods: Tacrolimus: β-cyclodextrin inclusion complexes (1:1 and 1:2 molar proportions) were prepared using the kneading method. Their characterization was accomplished by determining the drug content, solubility, Attenuated Total Reflection-Infrared Spectroscopy (ATR-IR), Scanning Electron Microscopy (SEM), Differential Scanning Calorimetry (DSC), and powder X-Ray Diffraction analysis (pXRD). These were then formulated to fast disintegrating tablets and evaluated for precompression as well as post compressional characteristics. Results: SEM analysis showed the inclusion complexes as rough, non-porous, irregular surfaced aggregate particles. DSC and pXRD analyses confirm the crystallinity change and partial conversion to the amorphous form of the drug in the inclusion complexes. From the solubility studies, it was observed that both the inclusion complexes of 1:2 molar ratio (14.82±0.889 µg/ml) and 1:1 molar ratio (12.72±0.1004 µg/ml) improved the aqueous solubility to greater extents in comparison to that of the pure drug (3.05±0.121 µg/ml). All the tablet formulations showed good precompression and mechanical properties. The inclusion complex loaded tablets exhibited a superior drug release pattern when compared to tablets prepared with tacrolimus alone. The optimized formulation (TT3) showed an in vitro disintegration time of 34.33 s and a percent drug release of 97.87. Conclusion: The inclusion complex formulation combined with the sublingual route of administration can be expected to result in an improved bioavailability of tacrolimus by increasing its solubility and bypassing first-pass metabolism.

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.
