davis1989 conducted metaanalysis of over 100 studies that compared effectiveness of antipsychotic drugs with placebos
over 70% patients treated with drug improved after 6 weeks
only 25% improved withplacebo
effective
altering levels of dopamine through use of antipsychotic drugs causes clear reduction of symptoms for majority of patients compared to placebo effect shortterm
means treatment works & biological approach to treating sz is accurate
X not 100% for davis?
research highlights that noteveryonebenefits from antipsychotics
effective for 70% showing that 30% people do not show improvements from taking drugs
? effective
does not improve everyones symptoms so may be bettertreatments that are more effective for wider sz population
X high relapse rates?
research has shown that 40%likelihood that sz patient will relapse within first year of taking antipsychotics & 15% relapse rates in later years
? effective
shows it isnt effective in helping patients with sz in longterm
may be better therapy to give lasting effects
* cheap & easy to administer?
taking drug is quick & simple as it only involves swallowing tablet
also cheap to obtain & can be readily available for nhs
suitable for wider range of individuals compared to psychological therapies such as cbt & family therapy which may be cognitively demanding
appropriate
due to low costimplications & being easy to do more people can successfullyaccess it increasing likelihood of being a chosentreatment for patients
X cannot give informed consent?
people with sz often suffer from hallucinations & delusions - delusions of persecution
fear someone will hurt them so may not be in right frame of mind to give informed consent as they may think treatment is made to harm them
? appropriate
patients with sz cant always give fully informed consent for acceptingtreatment & unethical to administer/difficult to ensure patients want to get on board with it
another treatment may be more appropriate
X side effects?
