Permeation Studies of Atenolol and Metoprolol Tartrate from Three Different Polymer Matrices for Transdermal Delivery
Since oral bioavailability of atenolol and metoprolol tartrate is poor, different matrix –type transdermal patches incorporating atenolol and metoprolol tartrate were formulated with an objective to study the effect of polymers on transdermal release of the drugs. The polymers selected were polyvinylpyrrolidone, cellulose acetate phthalate, hydroxypropylmethylcellulose phthalate and ethyl cellu...
متن کاملMetoprolol tartrate Containing Glutaraldehyde Cross-linked Chitosan- Polyvinyl pyrrolidone Matrix Transdermal Patch: Preparation and Characterization
The present study was undertaken to develop a suitable transdermal matrix patch of Metoprolol tartrate with different proportions of polyvinyl pyrrolidone (PVP) and chitosan crosslinked with glutaraldehyde (GA). The prepared transdermal patches were subjected to different physicochemical evaluations such as thickness, tensile strength, folding endurance, drug content, swellability, surface pH, ...
متن کاملDesign, development and in-vitro evaluation of metoprolol tartrate tablets containing xanthan-tragacanth.
The present study was undertaken to develop oral sustained release tablets of metoprolol tartrate using natural hydrophilic matrix formers (xanthan gum and tragacanth). Sustained release matrix tablets of metoprolol tartrate were prepared by using different ratios of drug, xanthan gum and tragacanth. Microcrystalline cellulose (MCC) was used as diluent. The polymer was incorporated into a matri...

متن کاملDrug Release Kinetics and Front Movement in Matrix Tablets Containing Diltiazem or Metoprolol/λ-Carrageenan Complexes
In this work we investigated the moving boundaries and the associated drug release kinetics in matrix tablets prepared with two complexes between λ-carrageenan and two soluble model drugs, namely, diltiazem HCl and metoprolol tartrate aiming at clarifying the role played by drug/polymer interaction on the water uptake, swelling, drug dissolution, and drug release performance of the matrix. The ...
