Programme 2. 01. 7 - MD simulations reveal molecular interactions that may facilitate interpretation of experimental data. Energy calculations enable estimates of amorphous miscibility. Water uptake and the influence of water on drug- excipient interactions can be explored. Water clustering leads to domains having enhanced mobility. Molecular dynamics (MD) computer simulations have shown promise in predicting various properties of amorphous excipients, amorphous drugs, and amorphous drug formulations. Structural, thermodynamic, and kinetic features that can be compared to experimental observations are of particular interest. MD simulations enable molecular level exploration of underlying molecular interactions of the excipients themselves, drug- excipient interactions, and the influence of water uptake.
At the cellular level, your body is a very busy place. Your cells create energy, secrete chemicals, expel waste, and many, many other functions. An antiporter (also called exchanger or counter-transporter) is a cotransporter and integral membrane protein involved in secondary active transport of two or more.

Thermodynamic properties such as the Flory- Huggins interaction parameter can be determined in order to predict amorphous drug miscibility with amorphous excipients and the solubility or dissolution rate enhancement potentially attainable through the use of amorphous systems. Dynamic properties related to molecular mobility are also of interest. Insights obtained from studies of various systems including polymer excipients (PVP, PVA, PLA, HPMC, and HPMCAS), several model drugs including indomethacin, felodipine, and carbamazepine, and their amorphous formulations at varying water contents will serve as examples in this presentation.
