No; that won't work.
-reshape- requires a subcommand, usually but not invariably -long- or -wide-.
See however <http://www.hsph.harvard.edu/cgi-bin/lwgate/STATALIST/archives/statalist.1010/date/article-207.html> for a suggestion in similar vein.

This should work:
sort id collect_date order_type, stable
by id collect_date order_type: gen seq=_n
reshape drug_code drug_result, i(id collect_date order_type) j(seq)
