Opis

In the present study, we have prepared matrix tablet formulations using Prazocin as a model drug and Ethyl Cellulose, Two grades of Hydroxy Propyl Methyl Cellulose- HPMC-K4M & HPMC-K100M as polymers in different ratios. The developed matrix tablets were evaluated for different physical-chemical evaluations like drug content, hardness, friability, swelling index etc. All the formulations had shown the results within prescribed limits. The In vitro drug release study indicates that formulation PCF-7 containing EC, HPMC K100M in 1:2 ratio shown good release pattern for 14 hours compares to other formulations. The short-term stability study proved no change in the formulation of ageing and it indicates good stability.
