What's the difference between efficacious and efficacy?

Efficacious


Definition:

  • (n.) Possessing the quality of being effective; productive of, or powerful to produce, the effect intended; as, an efficacious law.

Example Sentences:

  • (1) In conclusion, the efficacy of free tissue transfer in the treatment of osteomyelitis is geared mainly at enabling the surgeon to perform a wide radical debridement of infected and nonviable soft tissue and bone.
  • (2) The rise of malaria despite of control measures involves several factors: the house spraying is no more accepted by a large percentage of house holders and the alternative larviciding has only a limited efficacy; the houses of American Indians have no walls to be sprayed; there is a continuous introduction of parasites by migrants.
  • (3) Treatment termination due to lack of efficacy or combined insufficient therapeutic response and toxicity proved to be influenced by the initial disease activity and by the rank order of prescription.
  • (4) These findings raise questions regarding the efficacy of medical school curriculum in motivating career choices in primary care.
  • (5) Accidentally discovered nearly 40 years ago as the first true antidepressants, the MAOIs soon fell into disfavor due to concerns about toxicity and seemingly lesser efficacy compared with the newer tricyclic compounds.
  • (6) In patients who had undergone gastric operations, the efficacy of a parenteral rehabilitation with plasma, human albumin and Aminofusin L forte was determined by assessing the extravascular albumin pool.
  • (7) It is especially efficacious in evaluating patients with cystic lesions, especially those with complex cysts not clearly of water density.
  • (8) The efficacies of pefloxacin, fosfomycin, and both of these agents in combination against methicillin-resistant Staphylococcus aureus were assessed in a rat endocarditis model.
  • (9) It is concluded that extradural adrenaline does not usefully reduce systemic absorption of 0.5% bupivacaine, but may improve its efficacy in extradural anaesthesia for elective Caesarean section.
  • (10) Efficacy and tolerability of perorally administered desmopressin were evaluated in 12 adult patients suffering from central diabetes insipidus.
  • (11) We evaluated the safety and efficacy of a conjugate vaccine that links the H. influenzae type b capsular polysaccharide to the outer-membrane protein complex (OMPC) of Neisseria meningitidis serogroup B.
  • (12) Addition of IL7 either alone, or in combination with low doses of IL2, resulted in the generation of CTL with significantly (6-8-fold) enhanced therapeutic efficacy in vivo.
  • (13) The efficacy of the process is dependent on immersion medium, while the degree of surrounding tissue damage is dependent on energy dose.
  • (14) However, self-efficacy (defined as confidence in being able to resist the urge to drink heavily) assessed at intake of treatment, was strongly associated with the level of consumption on drinking occasions at follow-up.
  • (15) The objective of this work was to determine the efficacy of an endoscopic approach coupled to a Nd:YAG laser fiber in performing arytenoidectomy.
  • (16) and (4) Compared to the instruction provided by instructors from other medical and academic disciplines, do paediatric residents perceive differences in the teaching efficacy and clinical relevance of instruction provided by paediatricians?
  • (17) A prospective randomized trial involving 64 patients with bleeding peptic ulcers was performed to assess the efficacy of two modalities of injection therapy.
  • (18) A randomised double-blind trial comparing this preparation with a so-called 'shotgun' combination containing 0.05% betamethasone 17-valerate, 0.1% gentamicin, 1.0% tolnaftate and 1.0% clioquinol in 288 patients in the Philippines resulted in a better efficacy for the diflucortolone preparation in the 80 patients with bacterially or mycotically infected skin diseases.
  • (19) With attention to proper performance and patient selection, spinal and epidural anaesthesia are safe and efficacious options when choosing anaesthetic technique.
  • (20) How useful is the technique for evaluating therapeutic efficacy?

Efficacy


Definition:

  • (n.) Power to produce effects; operation or energy of an agent or force; production of the effect intended; as, the efficacy of medicine in counteracting disease; the efficacy of prayer.
