Efexor XR 75mg

Efexor XR general information

What is Efexor XR used for?

Efexor XR capsules 75mg (also known as Effexor XR in the US) are used to treat major depression and symptoms of depressive illness, including anxiety, loss of interest in usual activities, disturbed sleep, change in appetite, fatigue, feelings of worthlessness or guilt, difficulty thinking or concentrating, and recurrent thoughts of suicide. Efexor XR capsules 75mg are also used to treat other mood disorders that affect daily activities and relationships with others including, social anxiety disorder (Social Phobia), panic disorder (panic attacks) and generalised anxiety disorder.

How does Efexor XR work?

Efexor XR capsules 75mg (also known as Effexor XR in the US) contain venlafaxine which is an antidepressant belonging to the class of drugs known as Serotonin-Noradrenaline Reuptake Inhibitors (SNRIs), but is structurally and chemically different to other antidepressants. Venlafaxine in Efexor XR capsules 75mg acts in the brain to correct the chemical imbalance caused by a lack of certain neurotransmitters (brain chemical that allows nerve cells to communicate) that is thought to be one of the major causes of depression and other mood disorders, particularly a lack of serotonin, which controls many body activities, including regulating mood. Venlafaxine is a potent inhibitor of the reuptake of serotonin and noradrenaline, and also weakly inhibits dopamine reuptake, which means that it blocks the re-uptake of serotonin and noradrenaline from the synapse (the gap between nerve cells across which chemical messages are sent from one nerve cell to another). If the re-uptake of serotonin and noradrenaline by the first nerve cell (pre-synaptic) is blocked, this means that there is more neurotransmitter remaining for the receiving nerve cell (post-synaptic), which allows nerve cells to communicate with each other for longer. The action of Efexor XR capsules 75mg helps relieve symptoms of depression and other mood disorders by increasing the amount of serotonin and noradrenaline in the brain, which in turn increases stimulation of nerve pathways that control mood. Efexor XR capsules 75mg are formulated so that venlafaxine is released slowly from spheroids within the capsule into the digestive system for extended-release of the drug.

Treating depression with Efexor XR

Efexor XR capsules 75mg (also known as Effexor XR in the US) contain venlafaxine which is an antidepressant belonging to the class of drugs known as Serotonin-Noradrenaline Reuptake Inhibitors (SNRIs), used to treat symptoms of depression, including anxiety, loss of interest in usual activities, disturbed sleep, change in appetite, fatigue, feelings of worthlessness or guilt, difficulty thinking or concentrating and recurrent thoughts of suicide. One of the major causes of depression is thought to be an imbalance of neurotransmitters (brain chemicals that allows nerve cells to communicate), particularly a lack of serotonin that controls mood. Efexor XR capsules 75mg works by specifically blocking the reuptake of serotonin and noradrenaline from the synapse, or gap between nerve cells across which chemical messages are sent to allow nerve cell to communicate with each other. By preventing the reuptake of serotonin and noradrenaline by the first nerve cell (pre-synaptic) there is more neurotransmitter remaining for the receiving nerve cell (post-synaptic), so that nerve cells can communicate with each other for longer which increases stimulation of nerve pathways that control mood changes, relieving symptoms of depression.

Treating anxiety with Efexor XR

Efexor XR capsules 75mg (also known as Effexor XR in the US) contain venlafaxine which is an antidepressant belonging to the class of drugs known as Serotonin-Noradrenaline Reuptake Inhibitors (SNRIs), used to treat several anxiety-related conditions, including social anxiety disorder (Social Phobia), panic disorder (panic attacks) and generalised anxiety disorder, where excessive anxiety causes constant and uncontrollable feelings of worry and distress, making you feel irritable, and have difficulty thinking and sleeping. Other common symptoms associated with anxiety may include muscle tension, dry mouth, a lump in the throat, cold clammy hands, diarrhoea and nausea. One of the major causes of anxiety is thought to be an imbalance of neurotransmitters (brain chemicals that allows nerve cells to communicate), particularly a lack of serotonin that controls mood and noradrenaline that is related to drive and motivation. If there is a lack of serotonin, the brain cells involved in nerve pathways that control mood changes generate feelings of anxiety and panic instead of well-being, which is associated with high levels of serotonin. Efexor XR capsules 75mg works by specifically blocking the reuptake of serotonin and noradrenaline from the synapse, or gap between nerve cells across which chemical messages are sent to allow nerve cell to communicate with each other. By preventing the reuptake of serotonin and noradrenaline by the first nerve cell (pre-synaptic) there is more neurotransmitter remaining for the receiving nerve cell (post-synaptic), so that nerve cells can communicate with each other for longer which increases stimulation of nerve pathways that control mood changes, relieving symptoms of anxiety.
