Apologies! We want non-members to be able to open up to three "premium articles" (including 1 CPD) in a month without paying to subscribe. This is meant as a try-before-you-buy taster, but we hope that the offer will also help non-pharmacists who very occasionally have a reason to visit the site. However, the metering operates when you open any premium article, so clicking on one but not reading it, or re-reading one, will count against the total.
Please see the explanation of the access levels at http://www.pharmaceutical-journal.com/information/access-rules and feel free to report at this site (Pharmaceutical Press support) if you do not get access to two extra articles after completing a registration form.
