Venlafaxine vs Lexapro

Venlafaxine and Lexapro are medications used to treat mental health problems, such as Major Depressive Disorder (MDD) and Generalised Anxiety Disorder (GAD). Both of these medications are widely used in the process of dealing with depression and helping to overcome it. Let us get to know more about Venlafaxine and Lexapro (Praag, H., 2010).

What is Venlafaxine?

Venlafaxine is an antidepressant drug and is a part of the drug class named Selective Serotonin and Norepinephrine Reuptake Inhibitors (SSNRI). Venlafaxine hydrochloride is the active ingredient present in Venlafaxine. Along with being used as a medication for depression, Venlafaxine is also used for the treatment of other mental health disorders such as anxiety and panic disorder.

What is Lexapro?

Similar to Venlafaxine, Lexapro is also an antidepressant. Escitalopram is the generic name of Lexapro. It is a member of the drug group Selective Serotonin Reuptake Inhibitor (SSRI). It has Escitalopram oxalate as its active ingredient. Lexapro is also used for anxiety problems.

How Venlafaxine Works?

Venlafaxine is a part of the SNRI drug class in which the drugs affect the chemicals present in the brain to eradicate mental problems. Venlafaxine helps promote the rise of chemical substances such as Norepinephrine and Serotonin by blocking their reuptake, which decreases depression symptoms. It helps to cheer up the mood and restrict the mind from getting into the loop of negative thoughts.

How Lexapro Works?

Lexapro contains Escitalopram which affects the chemicals present in the brain which may make a person feel depressed or anxious. It affects the neurotransmitters and eliminates their imbalance by preventing the reuptake. This balance in chemicals helps maintain proper mental health and decreases the chance of a person getting depressed or anxious. 

Dosages for Venlafaxine

Venlafaxine is an oral medication, and it is available in the form of tablets, capsules, and extended-release capsules. It can be taken with food daily at the same time without crushing the capsules and tablets.

For the treatment of GAD, the initial amount of dose can be 75 mg per day. 

The maximum amount of dose of Venlafaxine for GAD is 225 mg per day, and it should not exceed that to prevent further negative consequences.

For treatment of depression, an adult can start medication with an initial dose of 75 mg per day, which can be distributed in two doses of 37.5 mg each or 3 doses of 25 mg each.

The maximum dose for depression depends upon the condition and the stage at which the person faces depression. 

225 mg per day is the maximum dose limit for moderately depressed people, while the dose turns to 375 mg per day if the person is in severe depression.

Dosages for Lexapro

Lexapro is an oral medication that is available as tablets, capsules, and liquid. A proper dose-measuring device should be used while taking liquid Lexapro.

For GAD and Depression, the amount of dosage is the same.

The initial dose for an adult is 10 mg per day which can be taken to 20 mg per day as the treatment proceeds. 

But the maximum daily dosage of Lexapro is 20 mg and should not exceed the limit.

For children aged 12 and above, the initial dose can be 10 mg per day, increasing only if necessary to 20 mg per day after assessing for 3 weeks.

Venlafaxine v/s Lexapro: A Study Of Comparision

Study: This is the study comparing venlafaxine and Lexapro conducted by Robert J Bielski. Et al.

Methods: The experimentation was conducted by gathering the subjects diagnosed with major depressive disorder. The speculation was done throughout the 8th week, and results were procured in the 8th week. The study was conducted based on surveying the subjects through the Montgomery-Asberg Depression Rating Scale (MADRS) on the dosage of venlafaxine (20mg) and Lexapro (225mg), respectively.

Results: The results found on the MADRS scale were as follows; for venlafaxine, the result found was N= 97, and in the case of Lexapro, the result found was N= 98. The venlafaxine XR group had a higher incidence than the Lexapro group of treatment-emergent adverse events (85.0% vs. 68.4%), and many discontinued due to adverse events.

Conclusion: Lexapro is at least as effective as venlafaxine XR and significantly potent. These results do not support the meta-analysis that nonselective SRIs have greater efficacy than selective SRIs.

Which is better Venlafaxine Or Lexapro?

Both Venlafaxine and Lexapro are used for medication for the same problem- Depression. The effectiveness of both these drugs is similar and much higher as compared to other antidepressants. But, due to the side effects of Venlafaxine, which can cause more trouble, doctors may shift towards prescribing Lexapro. But both these drugs are equally effective and can be prescribed depending upon the medical health and doctor (Eckert, L. and Lançon, C., 2006).
