Trazodone in Depression - A Comprehensive Review

Introduction:

Feeling very sad or worried, called depression, happens to a lot of people — about 19 million in America! If you or someone in your family can’t sleep because they feel gloomy or scared, a special medicine called Trazodone might help them feel better. But remember, only a doctor can give you this medicine.

Most people do okay with this medicine, but knowing that it can work differently for everyone is important. Doctors sometimes choose Trazodone when other medicines don’t help. It was approved by the US FDA (United States Food and Drug Administration) to help people feel better on February 2, 2010.

Drug Group

Trazodone is a drug in the class of serotonin antagonist and reuptake inhibitor (SARI).

What Are Trazodone Uses?

Trazodone uses:

• Trazodone helps with depression.

• Trazodone can also assist individuals in sleeping when other sleep medications are not effective.

• In some cases, physicians prescribe Trazodone to assist with feeling anxious or fearful, though it's not specifically designed for that purpose.

Other Uses: Doctors can also prescribe it to assist with other issues such as OCD (when one has huge concerns and repeats things repeatedly), panic attacks, or unpleasant memories of frightening events that occurred (referred to as PTSD). However, before prescribing Trazodone, doctors ensure it's the correct decision for the individual in need.

Dosage Forms and Available Strengths: What are Those?

Trazodone is available as tablet form. It is taken through the mouth.

Immediate-Release Tablets:

• 50 mg.

• 100 mg.

• 150 mg.

• 300 mg.

Extended-Release Tablets:

• 150 mg.

• 300 mg.

What Are the Warnings and Precautions?

• Feelings of Sadness or Harm: Some kids and young people felt more sad or had scary thoughts after taking this medicine. Doctors looked at many people and found that more kids and young adults had these feelings when taking the medicine than those who took a pretend pill (called a placebo). But no kids in the studies hurt themselves.

• Too Much of a Brain Chemical (Serotonin Syndrome): This medicine can make too much of a brain chemical called serotonin. That can make you feel sick, with signs like being really shaky, confused, very hot, or having a fast heartbeat. If that happens, stop the medicine and tell the doctor right away.

• Heart Problems: This medicine might not be safe for people with heart problems. It can make your heartbeat strange, so doctors need to be careful and watch closely if someone has heart trouble.

• Dizzy or Fainting: Some people might feel dizzy or fall down after standing up, especially if they take other blood pressure medicines too.

• Bleeding More Easily: This medicine can make it easier for you to bleed. If you're also taking medicine like aspirin, you should be careful. Tell your doctor if you see bruises or bleeding that won’t stop.

• Painful Problem for Boys (Priapism): Boys taking this medicine sometimes get a painful problem where their private part stays hard for a long time. If that happens, go to the doctor or hospital right away.

• Feeling Too Happy or Excited (Mania): Sometimes, people who take this medicine start feeling too excited or acting wild. If someone has ever had big mood changes before, they should tell the doctor.

• Stopping the Medicine Too Fast: If you stop taking the medicine suddenly, it might make you feel sick or dizzy. It's better to stop slowly with help from the doctor.

• Feeling Sleepy or Clumsy: This medicine can make you sleepy or not think clearly. Be careful with bikes, cars, or tools until you know how they make you feel.

• Eye Pressure Problem: Medicine might cause problems with the eyes for some people. If your eyes start to hurt or you can’t see well, tell the doctor right away.

• Low Salt in the Body (Hyponatremia): Some people might not have enough salt in their bodies after taking this medicine. That can make them feel confused, weak, or even faint. Older people or those taking water pills are more likely to have this happen.

For Patients

How Does Trazodone Work?

Trazodone helps a brain chemical called serotonin work better. Serotonin helps people feel happy. The medicine keeps serotonin in the brain longer, which might help people feel better.

Even though it’s made to help with sadness, Trazodone can also make people feel sleepy. That’s why some doctors use it to help people sleep, even though the company that makes it didn’t plan for it to be a sleep medicine.

What Is the Dosage of Trazodone?

Trazodone is a kind of medicine that you swallow like a pill. You take it by mouth.

In the U.S., it comes in different sizes, such as 50, 100, 150, and 300 mg (That just means how strong the medicine is).

You might take it after eating so you don’t feel dizzy.

Why Do People Take It?

1. For Feeling Very Sad (Depression):

• People might take it 2 or 3 times a day. They start with a small amount and slowly take more if the doctor says it's okay.

• Some people take up to 400 or even 600 mg a day if they are in the hospital.

2. For Trouble Sleeping (Insomnia):

• People usually take 50 to 100 mg before bed to help them sleep better.

Important Things to Remember:

• Only take what the doctor says.

• Don’t stop all at once—your doctor will help you take it less slowly when it’s time to stop.

• You can take it with other medicines, but only if your doctor says it’s safe.

Always ask a grown-up or doctor if you’re not sure!

What Are the Side Effects of Trazodone?

• Trazodone is often recommended as a medicine for insomnia due to its well-known sedative effects, which typically cause sleepiness. Additionally, users may experience dizziness, especially after standing up. A typical adverse effect is dry mouth, which can be avoided by drinking water, chewing gum, or eating sugar-free candies. Some people may have adverse responses such as nausea or upset stomach, constipation, and blurred eyesight. Some users also report having headaches.

• In some circumstances, Trazodone may cause anxiety or restlessness. Additionally, weight fluctuations, including both rises and dips, are possible for those using this medication.

What Are the Things to Inform the Doctor Before Taking Trazodone?

• Giving a complete medical history is essential, particularly in cases where there is a history of heart illness, liver or renal problems, bipolar disorder (people can feel super happy and full of energy, then later feel very sad or tired), seizures (the brain has mixed-up signals, kind of like when a TV gets fuzzy. This can make a person shake a lot (called convulsions) or even pass out for a little while), or when the patient is pregnant or nursing.

• All prescriptions, vitamins, and supplements must be disclosed to the healthcare professional because Trazodone may interact with other medications and have negative consequences.

• To prevent enhanced sleepiness or dizziness, it is essential to avoid alcohol and other stimulants while taking Trazodone.

• Let the doctor know if one has any allergies to Trazodone or its ingredients.

• Particularly in young adults, antidepressant drugs such as Trazodone may raise the risk of thinking about suicide. Following up with the healthcare professional and conducting routine monitoring is critical.

• Trazodone may cause serotonin syndrome; therefore, use caution when using it with other drugs that increase serotonin levels. Some symptoms include agitation, fast heartbeat, fever, muscle rigidity, and hallucinations.

Food Tips When Taking Trazodone:

When taking medicine like Trazodone:

• It’s a good idea to eat a little food first so you don’t feel dizzy.

• Don’t drink grapefruit juice, because it can change how the medicine works.

• Always ask your doctor what’s okay to eat or drink with your medicine.

What If You Forget to Take Your Medicine?

If you forget to take Trazodone:

• Take it when you remember.

• But if it’s almost time for the next dose, skip the one you missed.

• Don’t take two doses at once. That’s not safe.

What Are Overdose Symptoms?

If someone takes too much of a medicine called Trazodone, it can make their heart beat strangely, make it hard to breathe, or even make them very sleepy, like they’re in a deep sleep (called a coma). It can also cause a problem where a boy’s private part stays hard for too long, and that needs a doctor to fix it right away.

Sometimes, if a person takes a lot of Trazodone, it can hurt their brain and make them have seizures (shaking they can’t control). It can also make the salt in their body go too low, which can be dangerous.

Doctors help by giving care to keep the person safe, like helping them breathe or wake up. They also check their salt levels and help fix any problems. If someone is hurt from too much medicine, the doctors also call a special poison center to find out the best way to help.

Storage and Handling

• Temperature: Keep trazodone at room temperature, like how your house feels inside—not too hot, not too cold. Don’t let it freeze or get too warm.

• Light: Keep the medicine in its original box or bottle so bright light doesn’t hurt it.

• Moisture: Don’t store it in wet places like the bathroom. It needs to stay dry to work right.

• Safe Container: Make sure the medicine is in a childproof bottle so little kids don’t accidentally open it.

• Original Box: Keep the medicine in the box it came in. That way, grown-ups can see important info like how much to take and when it expires.

For Doctors

What Are the Pharmacological Actions of Trazodone?

What Is the Pharmacodynamics?

Trazodone helps you feel better by keeping more of the brain’s “happy chemical,” called serotonin. It helps your body relax, so you don’t feel as worried. It can also make you sleepy, which is why some people take it to help them fall asleep.

Pharmacokinetics:

• Absorbed in the Stomach: After taking a pill, it gets into the body through the stomach. Food can help it work better.

• Travels in the Blood: It spreads through the body and can reach the brain.

• Processed by the Liver: The liver breaks it down into parts that the body can use or get rid of.

• Leaves through Urine: Most of the medicine leaves the body in pee, a little in poop.

Toxicity:

Trazodone is a medicine that can make you very sleepy, especially if you take a lot or drink alcohol with it. It might make you feel dizzy or make your heart beat funny. Sometimes, it can cause serious problems like shaking or a fast heartbeat. Always take it only when a doctor says it's okay, and tell them if you feel bad after taking it.

What Are the Contraindications of Trazodone?

• Hypersensitivity: Trazodone should not be used by anyone who has a known allergy to the drug or any of its constituents.

• Monoamine Oxidase Inhibitors (MAOIs): Trazodone should not be taken with MAOIs or within 14 days after stopping them, because this can cause a dangerous condition called serotonin syndrome.

• Cardiac Conditions: Trazodone can affect how the heart beats by changing its rhythm. People with heart problems or taking other heart-related medicines should be careful and talk to their doctor before using it.

• Recent Myocardial Infarction (Heart Attack): People who have just experienced a heart attack need to exercise care while taking Trazodone.

• Seizure Disorders: Trazodone can decrease the seizure threshold. Individuals with a history of seizure or epilepsy should be monitored closely when on it.

What Are the Drug Interactions of Trazodone?

• CNS Depressants: Trazodone may increase the effects of alcohol, barbiturates, or other drugs that slow down the brain.

• CYP3A4 Inhibitors: A lower dose of Trazodone may be needed if taken with these drugs.

• CYP3A4 Inducers: A higher dose of Trazodone may be required when used with these drugs.

• Digoxin or Phenytoin: Blood levels of these drugs may rise, so monitoring is advised.

• Warfarin: Watch for changes in blood clotting time, as it may go up or down.

Clinical Studies:

This study is a single-dose, two-way crossover, fasting bioequivalence study using the 150 mg strength of Trazodone in healthy male and non-pregnant female volunteers. The 150 mg strength is selected due to safety concerns. Participants must not be taking antihypertensives, and the use of substances such as alcohol, Azole antifungals, barbiturates, Carbamazepine, CNS depressants, Digoxin, HIV (human immunodeficiency virus) protease inhibitors, Phenothiazines, Phenytoin, SSRIs (selective serotonin reuptake inhibitors), and warfarin is strictly prohibited. A fed study is not required. Trazodone levels will be measured in plasma, and bioequivalence will be assessed based on 90 % confidence intervals. A waiver for in vivo testing of the 300 mg strength is requested based on acceptable bioequivalence results from the 150 mg strength, satisfactory in vitro dissolution data, and proportional formulation similarity across strengths. Comparative dissolution testing must be performed on 12 units of all strengths, using media at pH 1.2, 4.5, and 6.8, with early and continued sampling until at least 80 % of the drug is released. Due to concerns about dose dumping with alcohol, additional dissolution testing is required using media with 0 %, 5 %, 20 %, and 40 % alcohol under specified conditions. For both test and reference products, the results must contain individual unit data, means, ranges, and the percent coefficient of variation (%CV).

Use in Special Populations

• Pregnancy: If someone is having a baby or wants to, they should talk to a doctor before taking this medicine.

• Breastfeeding: The medicine can get into a mom’s milk, so she should ask a doctor if it’s safe for the baby.

• Older Adults: Grandparents or older people may experience more side effects from this medicine.

• Children: Kids under 18 should not take this medicine because it might not be safe for them.
