    Sammanfattning : Hydrophilic matrix tablets are a compressed well mixed composite of drug substance and excipients including a hydrophilic polymer. When the tablet comes in contact with biological fluids, the hydrophilic polymer starts to dissolve, a process that decreases the water penetration through the tablet and involves dimensional changes of the tablet due to swelling of the solvated polymers.
