The present study deals with controlled drug delivery from hydrocolloid tablets by polymer particle erosion. The influence of excipients and formulation factors on the dissolution behaviour of the methyl hydroxyethyl cellulose (MHEC)-tablets is investigated. Linear drug release with low susceptibility
