Duovolt Er

Duovolt Er Uses, Dosage, Side Effects, Food Interaction and all others data.

Duovolt Er is a centrally-acting synthetic analgesic. It is 18 times less potent than morphine in terms of binding to human mu-opioid receptors. It also increases norepinephrine concentrations in the brains of rats via inhibition of norepinephrine reuptake. Selective mu-opioid antagonists like naloxone can block analgesia from tapentadol. It also has not effect on the QT interval.

Tapendadol causes large increases in levels of extracellular norepinephrine (NE) due to a dual mechanism of action involving mu opioid receptor (MOR) agonism as well as noradrenaline reuptake inhibition.

Dosage

Duovolt Er dosage

As with many centrally-acting analgesic medications, the dosing regimen should be individualized according to the severity of pain being treated, the previous experience with similar drugs and the ability to monitor the patient.

The dose is 50 mg, 75 mg, or 100 mg every 4 to 6 hours depending upon pain intensity. On the first day of dosing, the second dose may be administered as soon as one hour after the first dose, if adequate pain relief is not attained with the first dose. Subsequent dosing is 50 mg, 75 mg, or 100 mg every 4 to 6 hours and should be adjusted to maintain adequate analgesia with acceptable tolerability.

Daily doses greater than 700 mg on the first day of therapy and 600 mg on subsequent days have not been studied and are not recommended.

Pediatric use: The safety and effectiveness of Duovolt Er in pediatric patients less than 18 years of age have not been established.

Use in elderly patients: In general, recommended dosing for elderly patients with normal renal and hepatic function is the same as for younger adult patients with normal renal and hepatic function. consideration should be given to starting elderly patients with the lower range of recommended doses.

Use in Renal Disease: In patients with severe renal impairment, the safety and effectiveness of Duovolt Er has not been established.

Use in Hepatic Disease: Duovolt Er should be used with caution in patients with moderate hepatic impairment. Duovolt Er has not been studied in patients with severe hepatic impairment.

Side Effects

The following treatment-emergent adverse events may happen: heart rate increased, heart rate decreased, visual disturbance, abdominal discomfort, impaired gastric emptying, irritability, edema, drug withdrawal syndrome, hypersensitivity, involuntary muscle contractions, sensation of heaviness, hypoesthesia, paresthesia, disturbance in attention, sedation, dysarthria, memory impairment, ataxia, presyncope, syncope, coordination abnormal, seizure, urticaria, blood pressure decreased etc.

Toxicity

Oral, rabbit: LD50 = 3200 mg/kg; Oral, mouse: LD50 = 300 mg/kg; Oral, rat: LD50: 980 mg/kg; The most common reasons for discontinuation due to adverse events were dizziness, nausea, vomiting, somnolence, and headache.

Precaution

Duovolt Er should be administered with caution to patients with conditions accompanied by hypoxia, hypercapnia respiratory problems such as: asthma, chronic obstructive pulmonary disease etc. Besides this in case of patient with sleep apnea syndrome, myxedema, kyphoscoliosis, central nervous system (CNS) depression should have to be cautious prior administration of Duovolt Er. Patients receiving other mu-opioid agonist analgesics, general anesthetics, phenothiazines, other tranquilizers, sedatives, hypnotics, or other CNS depressants (including alcohol) concomitantly with Duovolt Er may exhibit additive CNS depression.

Interaction

Increased risk of serotonin syndrome with other drugs that enhance monoaminergic neurotransmission (e.g. TCAs, triptans, SSRIs, serotonin and norepinephrine reuptake inhibitors). Enhanced sedative effect with benzodiazepines, barbiturates, antipsychotics, H1-antihistamines and other opioids. Increased potential for addiction with mixed μ-opioid agonists/antagonists (e.g. nalbuphine, pentazocine) or partial μ-opioid agonists (e.g. buprenorphine). Increased systemic exposure with strong inhibitors of UGT1A6, UGT1A9 and UGT2B7 isoenzymes. Decreased efficacy with strong enzyme inducers (e.g. rifampicin, phenobarbital).

Food Interaction

  • Take with or without food. Food increases absorption, but not to a clinically significant extent.

[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.

Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.

Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.
