Tramadol - Uses, Dosage, and Side Effects

Introduction:

Tramadol is the most widely used and misused drug all over the world, so some insight is reviewed in this article. Tramadol was first patented in 1963 by a West German pharmaceutical company. It is sold under many brand names worldwide. It is a prescription drug that can be taken as an oral or injectable opioid agonist painkiller to relieve moderate to severe pain. It works by altering how the patient feels and responds to pain.

It is available in immediate-release, extended-release, and in combination with Paracetamol. It is a controlled substance; that is why it is available and used only under strict medical supervision.

What Is the Use of Tramadol?

It is a narcotic-like analgesic used to treat chronic and acute moderate to severe pain. It can also be used in combination with other medicines like Paracetamol.

The extended-release formulation is used in cases of chronic pain, as the drug has to work around the clock.

How Does Tramadol Work?

Tramadol works by acting on serotonin and norepinephrine, which are associated with pain sensations. This medicine relieves pain by lowering the levels of both serotonin and norepinephrine.

Tramadol is broken down to O-desmethyl Tramadol by liver enzymes. This O-desmethyl Tramadol binds to opioid receptors, which is where Morphine also binds, but it is a much more potent painkiller. However, Tramadol is only about 1/10th as effective as Morphine.

What Are the Recommended Dosages of Tramadol?

Tramadol is commercially available in the following doses:

• Immediate-Release - 50 mg.

• Extended-Release - 100, 200, and 300 mg.

Take this medicine only if the doctor prescribes it. The recommended dosage for moderate to severe pain in adults (age 18 to 64 years) is:

• Immediate-Release - 50 to 100 mg oral every four to six hours as needed. Not more than 400 mg/day.

• Extended-Release - Initially, 100 mg orally once a day. It can be increased by 100 mg/day every five days, but not more than 300 mg/day.

The recommended dosage for moderate to severe pain in older adults (above 65 years):

• Immediate-Release - 50 to 100 mg every four to six hours. Not more than 300 mg/day.

• Extended-Release - As the liver and kidneys of older adults are not very healthy, extended-release tablets are not recommended.

If the doctor prescribes this medicine, then do not stop taking it abruptly as soon as the pain stops, as it might cause withdrawal symptoms. So, taper the dose and then stop in one to two weeks. Consult a doctor to find safe ways to stop the use of medicine.

How to Use Tramadol?

Before administering Tramadol, one must undergo liver function tests and psychiatric evaluation, as its use may cause hepatotoxicity or drug abuse, respectively.

Take this medicine orally as prescribed by the doctor. It can be taken with or without food, but if the patient experiences nausea, it will help if taken along with food. It is usually started in a low dose and then adjusted depending on its effectiveness. Do not crush, chew, or dissolve the sustained-release pill.

After administration, blood pressure, liver function, and mental status should be monitored.

What Are the Drug Interactions of Tramadol?

Patients are advised to always tell their doctor about all the medicines, supplements, and herbs they are taking, as Tramadol can interact with them and cause serious side effects. Drugs that can increase the side effects of the drug taken or Tramadol are:

• Benzodiazepines (can result in sedation, respiratory depression, coma, and death).

• Serotonergic drugs (can cause serotonin syndrome).

• Selective serotonin reuptake inhibitors (SSRIs).

• Serotonin and norepinephrine reuptake inhibitors (SNRIs).

• Tricyclic antidepressants.

• Triptans.

• 5-HT3 receptor antagonists.

• Monoamine oxidase inhibitors (MOI).

What Is Tramadol Dependence?

Patients might become dependent on Tramadol if it takes more than a few weeks or months, but the potential for dependence is low compared to other opioid agonist drugs. However, people who are prone to addiction are more at risk.

Tramadol is a commonly prescribed synthetic analgesic. Two potential adverse reactions of this medicine are seizures and SS (serotonin syndrome). Either of these reactions may occur with Tramadol monotherapy, but both appear to be much more familiar with either abuse or overdose or in combination with other drugs, particularly antidepressants. In addition, these adverse reactions are more common in the elderly.

Most commonly prescribed antidepressants have been implicated in both of these adverse reactions. When prescribing antidepressants to patients on Tramadol, particularly in the elderly or those who might be at increased risk, such as individuals with epilepsy, head injuries, or neurological dysfunction. If coadministration is undertaken, careful monitoring is advised for these two particular hazards.

Tramadol Over Usage:

Overdosing and abusing Tramadol is one of the most common health issues. The most typical sign of Tramadol intoxication was seizures. Additional clinical signs and symptoms, such as anxiety, vomiting, nausea, coma, and respiratory depression.

What Are the Important Considerations for Tramadol?

These are some essential points that patients should be aware of before taking Tramadol:

• Tramadol increases the risk of seizures by altering the threshold level of neuron discharge.

• Tramadol should be avoided if patients have a suicidal tendency or are depressed.

• Avoid Tramadol in cases of breathing problems or taking serotonergic drugs.

• It is not recommended for patients who are prone to addiction.

• It can cause severe side effects if taken with alcohol.

• Never take it during pregnancy, as it can cause life-threatening withdrawal symptoms in the newborn.

• Tramadol is contraindicated for children under 12 years of age.

• Tramadol should not be used in cases of allergies to opioids.

Conclusion:

Tramadol is a great drug, but like all drugs, effective use entails balancing the benefits and risks. So, Tramadol is popular due to its properties of less respiratory depression and gastric tolerance. So, before starting this medicine, screening for risk factors should be done, and avoid using it in known cases of seizure, liver failure, and renal failure.
