According to Dr Shariq Qureshi, psychiatrist in Rajasthan - Targeting the right receptors in chronic depression treatment requires a deep understanding of neurobiology and the various neurotransmitter systems involved in mood regulation. Psychiatrists understand that Depression is thought to be linked to imbalances in several key neurotransmitters, including serotonin, norepinephrine, dopamine, and glutamate. Neuropsychiatrists focus on specific receptors in these pathways, so that medication strategies can be tailored to precisely target the right receptors involved. Key Neurotransmitter targets in Depression 1. Serotonin System : Serotonin (5-HT) is one of the most studied neurotransmitters in treatment of depression. The serotonergic system is targeted primarily through 5-HT1A receptors , which are involved in mood regulation. Medications used in depression treatment that influence serotonin activity include: - SSRIs (Selective Serotonin Reuptake Inhibitors) : These drugs inhibit the reuptake of serotonin, allowing more of it to remain available in the synaptic space. Commonly prescribed SSRIs by psychiatrists in India include Fluoxetine (Flunil) , Sertraline (Daxid) , and Escitalopram (Nexito) . - Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) : These drugs target both serotonin and norepinephrine reuptake. Examples include Venlafaxine (Veniz) and Duloxetine (Duzela) . 2. Norepinephrine System : Norepinephrine is another neurotransmitter implicated in depression, especially in cases involving fatigue and lack of motivation. Norepinephrine primarily acts on α1 and β-adrenergic receptors . Medications that enhance norepinephrine levels include: - SNRIs like Duloxetine (Duzela) and Desvenlafaxine (D-Veniz) . - Tricyclic Antidepressants (TCAs) such as Amitriptyline (Tryptomer) and Nortriptyline (Nortrip) , which increase both serotonin and norepinephrine. 3. Dopamine System : Dopamine is crucial for pleasure, motivation, and reward. In chronic depression, a deficiency in dopamine activity is often observed, particularly involving D2 and D3 receptors . Medications that target dopamine include: - Bupropion (Wellbutrin, Zyban) : Used by the top psychiatrists in India, this is a dopamine and norepinephrine reuptake inhibitor (NDRI) that can be helpful in patients with low motivation or pleasure. - Atypical Antipsychotics : Drugs like Aripiprazole (Abilify) and Quetiapine (Seroquel) , which modulate dopamine receptors, can be used as adjuncts to depressant treatment in jaipur. 4. Glutamate System : The glutamatergic system, especially through NMDA receptors , has gained attention in recent years for its role in treatment of depression in India. Dysfunction in this system can lead to altered neural plasticity according to the best psychiatrists in India. A newer class of medications targeting glutamate receptors includes: - Esketamine (Spravato) : An NMDA receptor antagonist that has shown rapid antidepressant effects, particularly in management of treatment-resistant depression. 5. GABA System : Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain, and its dysregulation can contribute to anxiety and depression symptoms. Modulation of GABA-A receptors is one therapeutic strategy in view of best depression doctor in jaipur. Benzodiazepines (e.g., Clonazepam ) act on these receptors. Multi-Receptor Approach for Treatment-Resistant Depression For patients who do not respond to conventional treatments, Best psychiatrist in jaipur combine medications that target multiple neurotransmitter systems to provide relief. Some common strategies include: - Atypical Antidepressants : Medications like Mirtazapine (Mirtaz) , which acts on both serotonin and norepinephrine receptors, can be useful in patients with insomnia and weight loss. - Augmentation with Atypical Antipsychotics : Drugs such as Olanzapine or Risperidone (Risperdal) are sometimes used to augment antidepressant effects, particularly by targeting dopamine and serotonin receptors. Individualized Treatment Choosing the right receptor targets by neuro doctors often depends on a patient’s unique symptom profile. Patients with significant anxiety may benefit more from SSRIs, while those with severe lethargy or cognitive slowing may require dopamine-enhancing medications like Bupropion . Chronic depression can also involve suicidality, necessitating a careful choice of medications by best psychiatrist in rajasthan to ensure patient safety. Understanding receptor dynamics allows jaipur psychiatrist to tailor the treatment, helping improve those suffering from chronic depression.
