Provided herein is rasagiline mesylate having a 90 volume-percent of the particles (D90) with a size of about 600 microns to about 1500 microns, and a process for the preparation thereof. Provided also herein are pharmaceutical compositions comprising rasagiline mesylate particles having a particle size which is suitable for homogeneous distribution of the drug substance in a tablet blend, in particular 90 volume-percent of the particles (D90) have a size of about 255 microns to about 1500 microns, and a process the preparation thereof.
摘要:
Provided herein is a highly pure deferasirox or a pharmaceutically acceptable salt thereof substantially free of hydrazine impurity, 4-hydrazinobenzoic acid, processes for the preparation thereof, and pharmaceutical compositions comprising highly pure deferasirox or a pharmaceutically acceptable salt thereof substantially free of hydrazine impurity.
摘要:
Provided herein are novel solid state forms of deferasirox salts, process for the preparation, pharmaceutical compositions, and method of treating thereof. The solid state forms of deferasirox salts are useful for preparing deferasirox (I) in high purity.
摘要:
The present invention relates to novel hemioxalate salt of eletriptan, process for preparation, pharmaceutical compositions, and method of treating thereof. The present invention relates to solid forms of eletriptan hemioxalate, processes for preparation, pharmaceutical compositions, and method of treating thereof. The solid form of eletriptan hemioxalate is useful for preparing eletriptan free base or a pharmaceutically acceptable salt thereof, particularly eletriptan hydrobromide, in high purity. The present invention also provides a process for preparing substantially pure eletriptan hydrobromide using eletriptan hemioxalate.
