Bilayer tablet making process involves certain challenges as well advantages. tablets are the prescriptions which comprise of two same or various medications consolidated in a solitary portion for viable treatment illness. Persistent consistence and cost measure significant boundaries treatments. manage these focuses adequately. To deliver decent quality bi-layer tablet, apparatus should be bui...

The purpose of this investigation is to formulate and evaluate the antihypertensive drug propranolol hydrochloride sustained-release bilayer tablets. In formulation, one layer provides a loading dose through immediate release other maintenance for up 12 h controlled release. Different quantities polymers such as Kyron T-314, Hydroxypropyl methylcellulose- K4M, ethyl cellulose were used make bi-...

This paper analyzes the effects of structures and loads on the static bending and free vibration problems of bilayer beams. Based on static mechanical equilibrium and energy equilibrium, the static and dynamic governing equations of bilayer beam are established. It is found that the value of the thickness ratio has a significant effect on the static and dynamic responses of the beam, and the st...
