  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Inefficacious  \In*ef`fi*ca"cious\,  a.  [Pref.  in-  not  + 
  efficacious:  cf  F.  inefficace,  L.  inefficax.] 
  Not  efficacious;  not  having  power  to  produce  the  effect 
  desired;  inadequate;  incompetent;  inefficient;  impotent. 
  --Boyle. 
 
  The  authority  of  Parliament  must  become  inefficacious  . 
  .  .  to  restrain  the  growth  of  disorders.  --Burke. 
 
  Note:  Ineffectual,  says  Johnson,  rather  denotes  an  actual 
  failure,  and  inefficacious  and  habitual  impotence  to 
  any  effect.  But  the  distinction  is  not  always  observed, 
  nor  can  it  be  for  we  can  not  always  know  whether  means 
  are  inefficacious  till  experiment  has  proved  them 
  ineffectual.  Inefficacious  is  therefore  sometimes 
  synonymous  with  ineffectual. 
 
  From  WordNet  r  1.6  [wn]:

  are  inefficacious  in  stopping  crime"  [ant:  {efficacious}]
