It looks like those are posts or pages that may have been created by a rogue admin user or a hacker who has access to your wp-admin. Check your useres, change your passwords and then look for pages and posts that you did not create.
I’ve checked all the users and reset all their passwords (I had to do it via the php my admin) as i was locked out.
I could not find the pages or posts though! That’s why it is so puzzling.
Try a direct query in PhpMyAdmin looking in the wp_posts table for any records with that content. Use something like this:
SELECT * FROM wp_posts WHERE post_content LIKE ‘%cialis%’ OR post_title LIKE ‘%cialis%’
