Section 4.5: Previously included a caution on inhibition of drugs metabolised by CYP 2C8 (eg. paclitaxel, rosiglitazone, and repaglinide) but that no in vivo interaction studies had been performed.
New information is now available from an interaction study and the statement has been revised to the following

However, data from a clinical drug-drug interaction study involving montelukast and rosiglitazone (a probe substrate representative of drugs primarily metabolised by CYP 2C8) demonstrated that montelukast does not inhibit CYP 2C8 in vivo. Therefore, montelukast is not anticipated to markedly alter the metabolism of drugs metabolised by this enzyme (eg., paclitaxel, rosiglitazone, and repaglinide)'.
 

Section 4.9:

Mainly  editorial changes and updated in line with post-market reports and most frequently occurring AEs consistent with montelukast safety profile. Some AE terminology re-defined. Previously: thirst, somnolence, mydriasis, hyperkinesia, abdominal pain.

Now: abdominal pain, somnolence, thirst, headache, vomiting, and psychomotor hyperactivity.
