Serotonin Antagonists And Reuptake Inhibitors
Serotonin antagonist and reuptake inhibitors while mainly used as antidepressants, are also anxiolytics and hypnotics. They act by antagonizingserotonin receptors such as 5-HT2A and inhibiting the reuptake of serotonin, norepinephrine, and/or dopamine. Additionally, most also act as α1-adrenergic receptorantagonists. The majority of the currently marketed SARIs belong to the phenylpiperazine class of compounds. They include trazodone and nefazodone.
Why Was This Study Needed
Depression is a common condition, affecting an estimated 1 in 10 adults at some point in their lives. Antidepressants are widely prescribed in primary and secondary care, along with psychological interventions such as cognitive behavioural or interpersonal therapy. There is conflicting evidence to guide which antidepressants should be prescribed first-line, although NICE recommends a selective serotonin reuptake inhibitor .
There has been uncertainty in recent years about the effectiveness of antidepressants. Their mode of action is poorly understood, and improvement in mood tends to be modest. One 2008 meta-analysis suggested that antidepressants gave little benefit over placebo for mild to moderate depression.
This new analysis went to some lengths to find unpublished studies and additional data from published studies, to give us the best overview of the current state of research.
Antidepressants List Of Names: Alphabetical Order
Antidepressants are medications that were developed to treat major depression. In addition to treating depression, many antidepressants have been found therapeutically beneficial for other conditions such as: anxiety disorders, eating disorders, obsessive compulsive disorder, and insomnia. There are many different types of antidepressants on the market for clinical use. A majority of antidepressants prescribed in the current era include: SSRIs and SNRIs.
However, there are other classes such as: atypical antidepressants, tricyclic antidepressants, and MAOIs that are typically used if a person doesnt respond to the newer classes of drugs. Included below is a comprehensive list of antidepressants that are currently available for clinical use throughout worldwide markets. Additionally below the initial list is a collection of antidepressant drugs that have been withdrawn from the market.

How Long Will You Have To Take Antidepressants
Usually, these drugs must be taken regularly for at least 4 to 8 weeks before their full benefit takes effect. You are monitored closely during this time to detect the development of side effects and to determine the effectiveness of treatment.
In order to prevent a relapse of depression, medicines are generally prescribed for 6 to 12 months after a first-time depression. When you and your provider determine that you are better, you should expect to continue the medication for at least 4 to 6 additional months. After this, your provider may gradually taper you off your medicine.
Is Fluoxetine Similar To Fluvoxamine
Fluoxetine and fluvoxamine are similar, but they do have some differences.
Both fluoxetine and fluvoxamine belong to a group of drugs called selective serotonin reuptake inhibitors . SSRIs are used to treat mental health conditions, such as depression.
Fluvoxamine is only used to treat obsessive-compulsive disorder . This is unlike fluoxetine, which is used to treat OCD, plus some other mental health conditions, including depression.
If you have more questions about how fluoxetine and fluvoxamine are alike and different, talk with your doctor or pharmacist.

Interactions With Other Drugs
Tricyclic antidepressants interacting with drugs from the group of neuroleptics, as well as tranquilizers, with narcotic-type analgesics increase their calming effect on the central nervous system, with anticonvulsant medications – weaken their influence on the patient’s body with hypnotics – increase oppression of the central nervous system with psychostimulants – strengthen their effect with diuretics – lead to drowsiness, lethargy, cause vomiting, promote the development of anorexia.
Neuroleptics enhance the effect of tranquilizers, hypnotics, anesthesia, muscle relaxants, narcotic analgesics and antihistamines.
Irreversible and reversible MAO inhibitors interact with narcotic analgesics – cause hypotension, convulsions, coma with hypothetical drugs – cause a contradictory effect with increased blood pressure with oral contraceptives increase the hepatotoxicity of contraceptives. The doctor, attributing the pill to depression, should indicate compatibility with other medicines.

Selective Serotonin Reuptake Inhibitors Side Effects
Selective serotonin reuptake inhibitors and serotonin/norepinephrine reuptake inhibitors are two classes of antidepressants associated with abnormal thinking, agitation, anxiety, dizziness, headache, insomnia, sexual dysfunction, sedation, tremor, sweating, weight loss, diarrhea, constipation, dry mouth, rash, and nausea. Rarely, SSRIs have been associated with hyponatremia , hypoglycemia , and seizures.

Missed Or Extra Doses
It’s important not to miss any of your doses, as this could make your treatment less effective.
If you do miss a dose, take it as soon as you remember, unless it’s almost time to take your next dose. In this case, you should just skip the missed dose. Don’t take a double dose to “make up” for the one you missed.
You should not take more than your prescribed dose unless advised by your doctor or prescriber. If you do take an extra dose by mistake, you should check with your pharmacist or medical professional for advice, or phone 111.
What Are Serotonin And Norepinephrine Reuptake Inhibitors How Do They Work
Serotonin and norepinephrine reuptake inhibitors or SNRIs are the newest class of antidepressants. SNRIs work by increasing the levels of serotonin and norepinephrine that are active in the brain. Serotonin and norepinephrine are produced by nerves and released into the surrounding tissues where they can attach to nearby receptors on other nerves, thereby stimulating the other nerves. The released serotonin and norepinephrine then are taken up and released again by the nerves that produce them. SNRIs block the uptake of the serotonin and norepinephrine so that more of the serotonin and norepinephrine are free in the tissues surrounding the nerves.
- Urinary retention: Urinary hesitation may be treated with bethanechol .
- Visual disturbances: Visual disturbances may be treated with pilocarpine eye drops.
- Sexual dysfunction:Erectile dysfunction may be managed with sidenafil , reducing the TCA dose, or discontinuing the TCA. Yohimbine, ginkgo, bethanechol, and neostigmine have also been used for managing TCA induced sexual dysfunction in some patients.
Side effects that are more serious include:
- TCAs also cause sedation. Amitriptyline , doxepin , and trimipramine are more sedating than amoxapine and desipramine . Sedation may improve after a few weeks of treatment. Sedating TCAs may be beneficial for depressed patients who have insomnia.
- Dose dependent and reversible weight gain may occur during TCA treatment. Amitriptyline causes weight gain more often than desipramine .

When To Consider Taking Ssris
Antidepressants like SSRIs are one method to help ease the symptoms of depression, but theyre typically just part of a treatment plan.
Your doctor may also recommend therapy, and if you chose to go, your therapist may have advice and methods to help you, depending on the severity of your symptoms and your personal history.
Some questions to ask yourself when youre considering SSRIs include:
- Do you feel as though your mental health condition is disrupting your life?
- Do you feel less pleasure when it comes to the things you used to enjoy?
- Do you consistently have trouble concentrating?
- Have you taken antidepressants before? If so, did they help? Were the side effects severe?
If you think you may have depression but arent sure, there are several screening questionnaires that can be helpful. Discussing the results with your doctor is a great first step.
Like SSRIs, serotonin-norepinephrine reuptake inhibitors keep the body from reabsorbing too much serotonin, allowing the brain to use more of it.
But unlike SSRIs, SNRIs also lessen the reuptake of the neurotransmitter norepinephrine.
SNRIs are sometimes used to treat nerve pain and certain anxiety disorders in addition to depression.
Some examples of SNRIs include:
Based on your symptoms and underlying conditions, you and your doctor will decide whether an SNRI or SSRI is the best option for you to try.
Tricyclic Antidepressants Side Effects
Tricyclic antidepressants are a class of antidepressant associated with sedation, dry mouth, blurred vision, constipation, urinary retention, and increased pressure in the eye. They are also associated with hypertension, abnormalheart rhythms, anxiety, insomnia, seizures, headache, rash, nausea, and vomiting, abdominal cramps, weight loss, and sexual dysfunction. Tricyclic antidepressants rarely cause liver failure.

Guidelines For Taking Antidepressants
The more you know about your antidepressant, the better equipped youll be to deal with side effects, avoid dangerous drug interactions, and minimize other safety concerns.
Some suggestions:
Follow instructions. Be sure to take your antidepressant according to the doctors instructions. Dont skip or alter your dose, and dont stop taking your pills as soon as you begin to feel better. Stopping treatment prematurely is associated with high relapse rates and can cause serious withdrawal symptoms.
Beware of drug interactions. Drinking alcohol can lessen the effects of some antidepressant medications. Dangerous drug interactions can also occur when SSRIs or SNRIs are taken with blood thinners, prescription painkillers, or antihistamines found in many over-the-counter cold and allergy medicines and sleep aids. Always talk to your doctor or pharmacist before combining medications.
Monitor side effects. Keep track of any physical and emotional changes youre experiencing and talk to your doctor about them. Contact your doctor or therapist immediately if your depression worsens or you experience an increase in suicidal thoughts. See your doctor on a regular basis.
Be patient. Finding the right drug and dosage is a trial and error process. It takes approximately four to six weeks for antidepressant medications to reach their full therapeutic effect. Many people try several medications before finding one that helps.
Questions To Ask Yourself And Your Doctor
- Is my depression adversely affecting my life enough to require drug treatment?
- Is medication the best option for treating my depression?
- Am I willing to tolerate unwanted side effects?
- What non-drug treatments might help my depression?

What Are The Implications
The findings are of interest to GPs and psychiatrists, who need to decide on the best initial treatment for adults with moderate to severe depression. The comparative data may help doctors select drugs with better efficacy and side-effects.
However, treatment choice will be guided by an individual patient’s circumstances and preferences. The meta-analysis was unable to look at the potentially different effects of treatment on subgroups based on age, sex, the severity of symptoms or duration of illness.
The review did not consider combined drug and psychological treatments, as recommended by NICE for moderate to severe depression, or long-term effects which limit its applicability.
Dosage For Premenstrual Dysphoric Disorder
Adult dosage
A doctor will typically prescribe sertraline in two ways:
- Continuous: The typical starting dose is 50 mg per day throughout your menstrual cycle. The dose may increase in the next cycles up to a maximum of 150 mg/day as needed.
- Luteal: The typical starting dose is 50 mg daily in the first two weeks before and up to the start of your anticipated period. Each cycle the dose may increase a bit up to a maximum of 100 mg/day.
Child dosage
The use of this drug to treat children with this condition has not been studied. It should not be used by people younger than 18 years.
Senior dosage
The kidneys of older adults may not work as well as they used to. This can cause your body to process drugs more slowly. As a result, more of a drug stays in your body for a longer time. This raises your risk for side effects. Your doctor may start you on a lowered dose or a different dosing schedule. This can help keep levels of this drug from building up too much in your body.
Disclaimer: Our goal is to provide you with the most relevant and current information. However, because drugs affect each person differently, we cannot guarantee that this list includes all possible dosages. This information is not a substitute for medical advice. Always speak with your doctor or pharmacist about dosages that are right for you.

Should You Treat Your Depression With Medications
You might be asking your healthcare provider this question if you have been feeling low and your friends and family have mentioned this to you. Your provider might have mentioned medication if your mood interferes with work, family or socializing for more than two weeks. Some people with depression might even have legal troubles linked to outbursts.
Interactions That Increase The Risk Of Side Effects
Taking certain medications with sertraline may result in increased side effects. These drugs include:
- Nonsteroidal anti-inflammatory drugs such as ibuprofen, naproxen, aspirin and warfarin. Taking these drugs with sertraline increases your risk of bleeding or bruising.
- Triptans such as sumatriptan. Your risk for serotonin syndrome is increased when you take these drugs with sertraline. Your doctor should watch you closely if you take these drugs together.
- Lithium. Taking this drug with lithium increases your risk for serotonin syndrome.
- Serotonergic medications such as fentanyl, tramadol, and St Johns wort. Taking these drugs with sertraline increases your risk for serotonin syndrome.
- Cimetidine. Taking cimetidine with sertraline may cause a buildup of sertraline in your body. Your dose of sertraline might need to be lowered if you take it with cimetidine.
- Tricyclic antidepressants such as amitriptyline, desipramine, and imipramine. Taking sertraline with these drugs may cause these drugs to build up in your body. Your doctor may need to adjust your dosage of tricyclic antidepressants while you take sertraline.
Sertraline oral tablet comes with several warnings.
Don’t Miss: What Should You Do If You Re Depressed
What Does Current Guidance Say On This Issue
The NICE 2009 guideline on depression advises that people with moderate to severe depression should be offered an antidepressant and psychological therapy such as cognitive behavioural therapy or interpersonal therapy. It says the antidepressant prescribed should normally be an SSRI in a generic form because SSRIs are equally effective as other antidepressants and have a favourable risk-benefit ratio.
The guideline warns that venlafaxine is more associated with risk of death from overdose than other SSRIs, while tricyclic antidepressants, except for lofepramine, are associated with the greatest risk in overdose.
The guideline, last updated in 2016, is under review.
Side Effects Of Antidepressants
Antidepressants can cause side effects at first, but these usually improve with time.
If you experience minor side effects, it’s important to continue treatment. This is because it can take several weeks before you begin to benefit from treatment. With time, you should find that the benefits of treatment outweigh any side effects.
During the first few months of treatment, you’ll usually see your doctor or a specialist nurse every 2 to 4 weeks. This will let them see how well the medication is working.
If you experience any severe side effects, you should let your specialist know.
For more information about your specific medication, see the patient information leaflet. This will be in the box with your medication.
Common side effects of SSRIs and SNRIs can include:
- feeling agitated, shaky or anxious
- feeling and being sick

Noncompetitive Nmda Receptor Antagonists
Memantine, which was approved by the FDA for the treatment of Alzheimer’s disease in 2013 and marketed by Forest Pharmaceuticals in the United States under the trade name Namenda® , is a selective low-affinity NMDA receptor antagonist that has been evaluated as a treatment for MDD. Unlike ketamine, memantine did not produce rapid or sustained antidepressant effects in clinical research. In fact, three clinical studies found that daily memantine was not superior to placebo for the treatment of MDD . A single clinical study found that daily memantine produced antidepressant effects in patients suffering from MDD comorbid with alcohol dependence, but it was not superior to the SSRI escitalopram . Memantine was generally well tolerated. Although ketamine and memantine possess similar binding affinity for the NMDA receptors, these NMDA antagonists do not produce similar antidepressant effects.
