Evaluation of Certain Pharmaceutical Quality Attributes of Lisinopril Split Tablets

Tablet splitting is an accepted practice for the administration of drugs for a variety of reasons, including dose adjustment, ease of swallowing and cost savings. The purpose of this study was to evaluate the physical properties of lisinopril tablets as a result of splitting the tablets either by hand or with a splitting device. The impact of the splitting technique of lisinopril (Zestril tablets, 20 mg) on certain physical parameters such as weight variation, friability, disintegration, dissolution and drug content were studied.
