Medications are commonly prescribed for depression, anxiety, bipolar and psychosis but also for addictions.
Most medications act on the brain and the most common brain target for medications are the monoamine transmitters: Serotonin, noradrenaline and dopamine.
The commonest are serotonin reuptake inhibitors (SSRI) eg sertraline, citalopram
Because they prevent reuptake there is more serotonin around.
There can be benefits in depression and anxiety
Those more likely to benefit are those with the more severe and more persistent symptoms.
Side effects : nausea, sexual, suicide / agitation?
Other similar drugs work on Noradrenaline and Dopamine– often with more side effects eg dry mouth, constipation. (eg amitriptyline)
Diazepam (a benzodiazepine) is an anxiolytic – it works on GABA, a transmitter which is an inhibitor in the brain.
It works quickly and is also sedative – can affect driving (more accidents than other meds) and also memory.
There are issues with tolerance and dependence.
Other short acting benzos are also used to help sleep – eg temazepam
Buspirone and pregabalin may also have benefits for anxiety
Bipolar: mania and depression
The main aim of medication is long term stability.
Lithium (a salt) should be considered but needs to be taken carefully and monitored.
Toxicity and rebound issues
Antidepressants may not be effective or even be destabilising
Antipsychotic drugs act to block dopamine
Olanzapine risperidone quetiapine
Side effects on movements and appetite / weight and sedation
