Fake Xanax anxiety pills from China seized in Zurich

Customs agents have seized one million fake anti-anxiety pills in transit at Zurich airport, Swiss officials say.

The four-crate shipment was on its way from China to Egypt, the Swiss Agency for Therapeutic Products said.

The tablets are counterfeit versions of Xanax - a drug manufactured by Pfizer to treat severe anxiety or panic disorder.

Tests showed the drugs contained no active ingredients, but would be very difficult to recognise as fakes.

The counterfeit drugs were packed into four crates which weighed over 400kg, said the agency, also known as Swissmedic.
