8 Questions
What is the purpose of hot melt extrusion in the pharmaceutical industry?
The purpose of hot melt extrusion in the pharmaceutical industry is to melt and force a mixture of pharmaceutical ingredients into various shapes such as granules, controlled release matrix tablets, pellets, and dissolving films.
How are solid dispersions made in the hot melt extrusion process?
Solid dispersions are made in the hot melt extrusion process by extruding the drug with immiscible components.
What is the subsequent step after creating solid dispersions using hot melt extrusion?
The subsequent step after creating solid dispersions using hot melt extrusion is molding the dispersions into films using dies.
What are some nanocarriers used to treat Alzheimer's disease?
Colloidal polymeric nanoparticles, phosphorus dendrimers, and colloidal dispersion of lipid nanoparticles
Which drug has been shown to have improved effectiveness in treating Alzheimer's disease when placed onto polymeric nanoparticles?
donepezil
What is the size range of nanoparticles that have been shown to deliver rivastigmine past the blood-brain barrier with greater effectiveness?
1 to 100 nm
Why are substantial doses of rivastigmine necessary to treat Alzheimer's disease?
Due to its limited penetration and high water solubility
Which compound was trapped in lipid nanoparticles for the Alzheimer's disease method?
ferulic acid
