This study presents the results of in vitro dissolution of sustained release propranolol
hydrochloride (PPN) matrix tablets using hydroxypropyl methyl cellulose K100M as a rate
retarding polymer. The effects of the proportion of the polymer and the influence of excipient
like microcrystalline cellulose on the release rate of drug was investigated. The results of the
present study point out that the rate of propranolol hydrochloride release from HPMC K100M
matrices are mainly controlled by the drug Ã?¢Ã?â?¬Ã?â??HPMC ratio. When the influence of excipients on
the release of drug was examined, the excipient microcrystalline cellulose enhanced the release
rate of propranolol hydrochlroid.
