Fetching Records with Date Comparision

Question

Hi friends, 
I have a table 'Medicine'

id name     expirydate
1A       04-06-2011 17:00:00
2B       04-06-2011 23:57:57
3C       04-06-2011 01:00:00
4D       04-05-2011 10:00:00
5E       04-07-2011 09:00:01

I want to find all medicine which expire on or before 04-06-2011.

select * from medicine where expirydate < getdate();

I fire this query on 04-06-2011 at 17:30:00
and got result
id name expirydate
1A      04-06-2011 17:00:00
3C      04-06-201101:00:00
4D      04-05-201110:00:00

it not contain record ID 2.
how can I find actual result which also contain record 2?
I can not use as 'expiryDate < getdate()+1'.

Thanks.
