Similarity of solid state structures of R- and S-isomers of clopidogrel hydrogensulphate salt.

The present study showed, that the crystal structures of R-isomer and the polymorphic form 1 of clopidrogrel hydrogensulphate S-isomer are very similar.

Physical characterization of pantoprazole sodium hydrates.

Only two crystal forms of pantoprazole sodium, i.e. mono and sesquihydrate, were described in the literature.
