Dear members of this list,

I would appreciate if anyone help me in order to get two articles
which is very helpfull for me in order to improve my work with
maphazoline.
The references are:

1) Synthesis and identification of the primary degradation product in
a
commercial ophthalmic formulation using NMR, MS, and a
stability-indicating HPLC method for antazoline and naphazoline.
J Pharm Sci. 1995 Apr;84(4):502-7.

2) High-performance liquid chromatographic stability-indicating assay
for naphazoline and tetrahydrozoline in ophthalmic preparations.
Thanks in advance for the help,
J Pharm Sci. 1983 Nov;72(11):1347-9. Links

Thanks a lot in advance,

Diego
