Which is a more potent anti-anxiety medicine?

Hello,

Welcome to icliniq.com.

Buspirone is a different drug than Escitalopram. Escitalopram is an SSRI (selective serotonin reuptake inhibitor) and helps improve serotonergic neurotransmission in the brain. The drug should be taken regularly in order to improve anxiety and depression. Buspirone is also a drug that improves serotonergic neurotransmission, but the drug usually helps control anxiety symptoms. The drug should be taken on an SOS basis, while in some conditions, this should be taken regularly. If we consider potency, then Escitalopram is more potent than Buspirone. Thanks and take care.

If we consider the first-line drugs, then SSRIs like Escitalopram, Citalopram, Fluoxetine, etc., are commonly used for anxiety. In some cases, Venlafaxine, Duloxetine, etc., can be used. If you do not see improvement with Escitalopram, then Buspirone can be used as an add-on. This will help supplement the actions of Escitalopram and will control your anxiety. You can consider this option.

When SSRI or SNRI medicine is started then the drug blocks the reuptake of neurotransmitters by immediate actions and with time, the drug causes changes at molecular levels or at synaptic levels. The receptor upregulation occurs and this results in the constant presence of neurotransmitters in the synapse and reduced degradation. This helps in strong actions and improvement of symptoms. I could not find any good study material in simple language on these but I am trying to make it simple for you. There are newer drugs like Vilazodone, and Vortioxetine which have actions similar to SNRIs or SSRIs but the mechanism of action is different. Even Mirtazapine can be tried in your case which is a Noradrenaline-specific serotonin antidepressant. This drug also has unique actions. Thanks.
