Oral drug administration has been the predominant route for drug delivery due to the ease of administration, patient convenience and flexibility in formulations. Mucoadhesive tablets of Cephalexin monohydrate were prepared with an objective to increase the bioavailability by minimizing the first pass metabolism and also to reduce the frequency of administration. Carbopol 934p as a primary polym...

In this work, the dissolution-absorption studies were conducted on marketed tablets of acyclovir (ACIVIR-200mg) and the mucoadhesive tablets of acyclovir using varying concentration of sodium lauryl sulfate as a permeation enhancer. The purpose of this study was to improve the absorption of acyclovir using sodium lauryl sulfate as permeation enhancer. The everted and perfused intestine model wa...

Purposes: Propranolol HCl is a beta blocker commonly used worldwide; however, it shows a low bioavailability due to its extensive first-pass metabolism. To solve this problem, a novel drug delivery system such as buccoadhesive system might be helpful. The aim of the present investigation is to prepare the buccoadhesive tablet of propranolol HCl using different mucoadhesive polymers. Method: Buc...

A new mucoadhesive tablet, which releases natural active agents for pain reduction and rapid healing of canker sores, has been prepared and characterized. Adhesive tablets were prepared by compression molding of mixed powders of crosslinked polyacrylic acid and hydroxypropyl cellulose, absorbed with citrus oil and magnesium salt. The rate of tablet erosion and the rates of citrus oil and magnes...

The study is related to the formulation and evaluation of mucoadhesive buccal tablets Anastrozole enhance its bioavailability by avoiding 1st pass effect. succeeded in developing containing two layers (mucoadhesive backing layer) a design that permits unidirectional release drug. Tablets were prepared double direct compression method using (carbopol 934) as primary polymer, Sod.alginate, Na CMC...

hypertension crisis is one of the main health problems and its effective treatment is of high importance. for this purpose, fast-disintegrating and sustained release formulations of captopril, as a drug of choice, were prepared using conventional mucoadhesive polymers hydroxypropyl methylcellulose (hpmc), sodium carboxymethyl cellulose (na-cmc), hydroxypropyl cellulose (hpc), carbopol 934 (cp93...

Oropharyngeal candidiasis (OPC) is among the most common opportunistic infections observed in persons infected with human immunodeficiency virus. A once-daily miconazole 50 mg mucoadhesive buccal tablet (MBT) is a novel delivery system with potent in vitro activity against many Candida species, including some that may be resistant to other azoles. MBT, although more expensive, offers an effecti...

Poorly water-soluble drugs, such as phenylephrine, offer challenging problems for buccal drug delivery. In order to overcome these problems, particle size reduction (to the nanometer range) and cyclodextrin complexation were investigated for permeability enhancement. The apparent solubility in water and the buccal permeation of the original phenylephrine coarse powder, a phenylephrine-cyclodext...
