Tramadol

Class

• Opioid Analgesic (Schedule IV Controlled Substance in some regions)

Indications

• Moderate to moderately severe pain (acute or chronic)
• Pain relief after surgery or injury
• Neuropathic pain (off-label use)

Mechanism of Action

• Binds to opioid receptors in the brain to reduce pain perception.
• Inhibits reuptake of serotonin and norepinephrine, modulating pain signals.

Dosage and Administration

Immediate-Release (IR) Tablets

• Starting dose: 50–100 mg every 4–6 hours as needed.
• Maximum dose: 400 mg/day.

Extended-Release (ER) Tablets

• For chronic pain requiring long-term management.
• Starting dose: 100 mg once daily; titrate up to 300 mg/day based on response.
• Swallow whole; do not crush or chew.

Pediatric Use

• Not recommended for children under 12 years.
• Contraindicated in post-operative pain management in children under 18 following tonsillectomy or adenoidectomy.

Geriatric Use

• Start at the lower end of the dosing range due to decreased renal or hepatic function.

Forms Available

• Immediate-release tablets: 50 mg.
• Extended-release tablets/capsules: 100 mg, 200 mg, 300 mg.
• Oral drops or solution.
• Injectable formulations (hospital use).

• Children under 12 or post-operative use in children under 18.

Precautions

• Risk of addiction, abuse, and misuse, even at prescribed doses.
• Use with caution in patients with a history of substance abuse.
• May cause serotonin syndrome when combined with other serotonergic drugs.
• Increased risk of seizures in patients with epilepsy or head injuries.
• Avoid alcohol and CNS depressants to reduce risk of sedation and respiratory depression.
• Use with caution in renal or hepatic impairment; dosage adjustment required.

Side Effects

Common

• Seizures.
• Severe allergic reactions (rash, swelling, difficulty breathing).

Drug Interactions

Increased Risk of Side Effects

• CNS depressants (e.g., alcohol, benzodiazepines): Enhanced sedation and respiratory depression.
• Serotonergic drugs (e.g., SSRIs, SNRIs, MAOIs): Risk of serotonin syndrome.

Reduced Effectiveness

• Carbamazepine: Reduces tramadol levels.
• CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): Decrease tramadol’s pain-relieving effects.

Avoid

• MAOIs within 14 days of tramadol use (risk of hypertensive crisis).

Monitoring Parameters

• Pain relief and functional improvement.
• Signs of misuse, abuse, or addiction.
• Respiratory function, especially in elderly or those with lung conditions.
• Symptoms of serotonin syndrome or seizures.

Patient Counseling Points

• Take tramadol exactly as prescribed; do not increase the dose without consulting your doctor.
• Do not combine with alcohol or sedatives.
• Swallow extended-release tablets whole to avoid overdose.
• Report severe side effects, such as difficulty breathing, confusion, or rapid heartbeat.
• Avoid driving or operating machinery until you know how the medication affects you.
• Keep tramadol in a secure place to prevent misuse by others.
• Dispose of unused medication properly to prevent accidental ingestion.

Q8: Can tramadol cause seizures?

• Yes, especially at high doses or in individuals with a history of seizures.

Q9: What’s the difference between tramadol and other opioids?

• Tramadol also works on serotonin and norepinephrine pathways, unlike traditional opioids like morphine.

Q10: Is tramadol suitable for neuropathic pain?

• It is sometimes used off-label for neuropathic pain, though other medications may be more effective.

Q11: How should I store tramadol?

• Store at room temperature in a secure location out of reach of children and pets.

Q12: Can tramadol be used in elderly patients?

• Yes, but at lower doses due to increased sensitivity to side effects like sedation and respiratory depression.
