From what I can see the media made up the drugging story themselves.
Let's see: the media forwarded the hypothesis that the children could have been sedated to be kept asleep and allow some rest to the parents.
Distant in time Kate's father, the grandfather of the minor, Brian Healy, admits to the press that Kate could have administered some medication to the little girl, Calpol, to help the child (children'') to sleep, contrary to what his daughter Kate had stated.
Kate, through the PJ inspector that acted as 'liaison' with the family [NOTE: that is Ricardo Paiva], asked why samples weren't taken from the twins in order to test that hypothesis. She knew well enough at that time, more than 3 months later, that such exam would be inviable.
She went further and said that we ' the investigation ' should verify that the kidnapper had sedated Madeleine, to accomplish the action and he had also sedated the twins 'to consummate the act' however she didn't say that at the right moment.
And we know that the sedatives have timings to act and timings to be expelled, that varies between six and 200 hours.
The medical knowledge of the McCann is enough to know such, even if their professional activity never passed by performing toxicology exams.

A report by Chief Inspector Tavares de Almeida to the Coordinator of the Criminal Investigation
http://www.mccannpjfiles.co.uk/PJ/TAVARES_ALMEIDA.htmModified to say perhaps all it really says is that Almeida didn't leak it and it was unlikely to be the police or he would have had an idea of what they were looking at when the stories broke, but it still could have been the McCanns but of course I cannot confirm this.
