Using zeta potential to study the ionisation behaviour of polymers employed in modified-release dosage forms and estimating their pKa
A range of enteric polymers is used in pharmaceutical industry for developing gastro-resistant formulations. It is generally implied that these coatings are interchangeable due to similar dissolution pH thresholds reported by suppliers. Despite rapid dissolution in compendial phosphate buffers, thes...
