Perhaps you should try some spelling variations:
"pharmacological agents/technology" » "pharmacological aspects/technology", "pharmacological management/technology", "pharmacological treatment/technology"
"pharmaceutical agents/technology" » "pharmaceutical aspects/technology", "pharmaceutical ingredients/technology"
"pharmaceutical drugs/technology" » "pharmaceutical drug/technology", "biopharmaceutical drug/technology", "pharmaceutical _/technology"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("pharmaceutical agents/technology") OR ("pharmaceutical drugs/technology"))) OR ("pharmacological agents/technology")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"pharmaceutical agents/technology\") OR (\"pharmaceutical drugs/technology\"))) or (\"pharmacological agents/technology\"))".
• Removing quotes may allow a broader search: (((( pharmaceutical agents/technology ) OR ( pharmaceutical drugs/technology ))) or ( pharmacological agents/technology )).
• Adding a wildcard symbol may retrieve word variants: (((("pharmaceutical agents/technology") OR ("pharmaceutical drugs/technology"))) or ("pharmacological agents/technology"))*.
