Development of fast release tablet of talinolol using fourth generation carrier of solid dispersion technique

Abstract

Talinolol is a beta1-selective adreno receptor antagonist well known for its Cardio protective and antihypertensive activity. Talinolol is a beta blocker. In biopharmaceutical classification system the drugs which come under class II are characterized by more membrane permeability, less dissolution rate. Talinolol is a poor aqueous solubility drug leads to poor bioavailability. So, the aimed of this study was to develop immediate release tablet of talinolol by solid dispersions technique using poloxamer 407 as a carrier. Poloxamer 407 is a hydrophilic synthetic block copolymer widely used as a solubility enhancer. Basically there are three methods used for solid dispersion. Melting or fusion method solvent evaporation method. Melting solvent method. Solvent Evaporation Method In this method a suitable solvent is selected which can capable of solubilizing both drug and hydrophilic carrier. The solvent evaporation technique is one of the most commonly used methods to prepare polymeric nanoparticles, more specifically drug-loaded polymeric systems, for pharmaceutical formulations. The prepared solid dispersions were evaluated for production yield percent, drug content, solubility, FTIR, and DSC study analysis. The prepared formulation of Talinolol with P407 in the ratio of 1:5 gave highest dissolution rate of 75.28% at 30min.So it can be concluded that the combination of solid dispersion technology as well as using superdisintergrants an encouraging and effective technique to prepare efficient fast dissolving tablets of Talinolol.The outcome of this investigation presents poloxamer 407 solid dispersion mediated fast dissolving tablets successfully resolve problem of slow rate of dissolution of talinolol.
