What is the recommended use and dosage of Ralivia ER (tramadol) for chronic pain management?

From the Guidelines

Ralivia ER (tramadol) is recommended for moderate to moderately severe chronic pain at an initial dosage of 100 mg once daily, which can be gradually increased by 100 mg every 5 days as needed, up to a maximum of 300 mg daily, as stated in the most recent guideline from 2022 1. For elderly patients (over 75 years) or those with renal or hepatic impairment, lower doses are recommended, starting at 100 mg daily with careful titration. The extended-release tablets should be swallowed whole, not crushed or chewed, and can be taken with or without food at the same time each day to maintain consistent pain control. Some key points to consider when prescribing Ralivia ER include:

• Patients should be aware that tramadol is an opioid medication that works by binding to mu-opioid receptors and inhibiting the reuptake of serotonin and norepinephrine, providing pain relief through dual mechanisms.
• Common side effects include dizziness, constipation, nausea, and sedation.
• Due to its potential for dependence and withdrawal symptoms, Ralivia ER should not be stopped abruptly but rather tapered gradually under medical supervision.
• Patients should avoid alcohol and other CNS depressants while taking this medication as these combinations can increase the risk of respiratory depression. It's also important to note that the CDC clinical practice guideline for prescribing opioids for pain recommends starting opioids at the lowest possible effective dosage and using caution when increasing opioid dosages, as overdose risk increases with dosage 1. Additionally, the guideline suggests that dosage increases beyond 50 MME/day are progressively more likely to yield diminishing returns in benefits for pain and function relative to risks to patients. Therefore, it is crucial to carefully evaluate the decision to increase the dosage of Ralivia ER and to implement additional precautions, such as increased frequency of follow-up and offering naloxone and overdose prevention education, when the patient's opioid dosage reaches or exceeds 50 MME/day.

From the FDA Drug Label

DOSAGE & ADMINISTRATION Adults (17 years of age and over) For patients with moderate to moderately severe chronic pain not requiring rapid onset of analgesic effect, the tolerability of tramadol hydrochloride tablets, USP can be improved by initiating therapy with a titration regimen: The total daily dose may be increased by 50 mg as tolerated every 3 days to reach 200 mg/day (50 mg q.i.d.) After titration, tramadol hydrochloride tablets, USP 50 to 100 mg can be administered as needed for pain relief every 4 to 6 hours not to exceed 400 mg/day For the subset of patients for whom rapid onset of analgesic effect is required and for whom the benefits outweigh the risk of discontinuation due to adverse events associated with higher initial doses, tramadol hydrochloride tablets, USP 50 mg to 100 mg can be administered as needed for pain relief every four to six hours, not to exceed 400 mg per day Individualization of Dose Good pain management practice dictates that the dose be individualized according to patient need using the lowest beneficial dose. In all patients with creatinine clearance less than 30 mL/min, it is recommended that the dosing interval of tramadol hydrochloride tablets be increased to 12 hours, with a maximum daily dose of 200 mg. The recommended dose for adult patients with cirrhosis is 50 mg every 12 hours. In general, dose selection for an elderly patient over 65 years old should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function and of concomitant disease or other drug therapy. For elderly patients over 75 years old, total dose should not exceed 300 mg/day.

The recommended use and dosage of Ralivia ER (tramadol) for chronic pain management is as follows:

• Initial dose: Start with a titration regimen to improve tolerability, increasing the total daily dose by 50 mg every 3 days to reach 200 mg/day.
• Maintenance dose: After titration, administer 50 to 100 mg as needed for pain relief every 4 to 6 hours, not to exceed 400 mg/day.
• Dose adjustment: Individualize the dose according to patient need using the lowest beneficial dose.
• Special populations:
  • Renal impairment: Increase dosing interval to 12 hours with a maximum daily dose of 200 mg for patients with creatinine clearance less than 30 mL/min.
  • Hepatic impairment: Recommended dose for adult patients with cirrhosis is 50 mg every 12 hours.
  • Elderly patients: Start at the low end of the dosing range and do not exceed 300 mg/day for patients over 75 years old 2.

From the Research

Recommended Use and Dosage of Ralivia ER (Tramadol) for Chronic Pain Management

• Ralivia ER (tramadol) is an extended-release formulation of tramadol, a centrally acting analgesic used for the treatment of moderate to moderately severe pain 3.
• The recommended dosage of Ralivia ER for chronic pain management is not explicitly stated in the provided studies, but it is mentioned that tramadol is available as sustained-release tablets that release the active ingredient over a period of 12 hours, with a bioavailability of 87-95% compared to capsules 4.
• Tramadol is generally well-tolerated and effective in reducing pain resulting from trauma, renal or biliary colic, and labor, as well as for the management of chronic pain of malignant or nonmalignant origin, particularly neuropathic pain 4.

Pharmacokinetics and Pharmacodynamics of Tramadol

• Tramadol is rapidly and almost completely absorbed after oral administration, with a mean elimination half-life of about 6 hours 4.
• The O-demethylation of tramadol to its main analgesic effective metabolite, M1, is catalyzed by cytochrome P450 (CYP) 2D6, whereas N-demethylation to M2 is catalyzed by CYP2B6 and CYP3A4 4.
• The wide variability in the pharmacokinetic properties of tramadol can partly be ascribed to CYP polymorphism, and O- and N-demethylation of tramadol as well as renal elimination are stereoselective 4.

Potential Risks and Side Effects of Long-Term Tramadol Use

• Long-term utilization of tramadol is associated with various neurological disorders, such as seizures, serotonin syndrome, Alzheimer's disease, and Parkinson's disease 5.
• Tramadol may produce seizures through inhibition of nitric oxide, serotonin reuptake, and inhibitory effects on GABA receptors, and extensive tramadol intake can alter redox balance, leading to neurotoxicity and neurobehavioral deficits 5.
