Drug Treatments for Anorexia

Question 1

Drug treatments for AN

Answer 1

Drug treatments are used for AN as it is thought certain NTs are linked to the disorder, such as serotonin and dopamine

Antidepressants -
SSRIs reduce the reuptake of serotonin at the synapse so more is available for transmission. It is thought that low serotonin may play a role in the disorder

SNRIs - Targets noradrenaline as well a serotonin

Antipsychotics - Dopamine levels in AN thought to be abnormally high so antipsychotics can block dopamine receptors. This means that the normal rewarding function of eating can remain so appetite can be increased

SGAs - Affect several other NTs other than dopamine, one main example of an SGA is olanzapine

Strengths

• Boachie (2003) used Olanzapine (SGA) to treat 4 patients. Significant weight gain and less anxiety in mealtimes
• Side effects such as dry mouth and headaches, but these are not serious and can be monitored carefully through blood tests. This knowledge helps the acceptability of drug treatments

Weaknesses

• Lebow (2013) found that SGAs did increase BMI, but so did the placebos. Found WORSE anxiety and symptoms
• Focus on the symptoms rather than cause. Temporary and stops working when drug isn’t taken. CBT might be preferable
