“…For this reason, timely access to this product should be a priority for health care authorities but might be blocked by the patent holder. chirality as a patent protection policy was explored recently in the case of citalopram, as a racemic mixture of (S)-(+)-and (R)-(-)-enantiomers (27), and the question remains about the real added novelty in case of additional patent protection of its enantiomers, which motivated our interests in the topic (3). the aim of this study was to analyze the patent policy for escitalopram protection as an enantiomer of citalopram and the effect of this policy on the penetration of generic molecules on the market.…”
