Opan Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Opan is a brand name. Its generic name is Tramadol.

Opan

Opan, (generic name: tramadol hydrochloride), is an opioid medication used to treat moderate to severe pain. It is an opioid agonist, meaning it stimulates opioid receptors in the brain, activating them and producing an analgesic effect. Opan also works on serotonin and norepinephrine receptors, further enhancing its pain-relieving effect. Opan is available in both immediate-release and extended-release forms.

Uses For Opan

Opan is prescribed to treat moderate to severe pain in both adults and children, as well as in adolescents between the ages of 12 and 18. It is also used off-label to treat pain associated with fibromyalgia, painful neuropathy, and headaches. Because of its opiate-like effects, Opan is sometimes prescribed for the treatment of opioid dependence.

Mechanism Of Action

Opan works by binding to opioid receptors in the brain and spinal cord, and increasing the activity of serotonin (which helps reduce the pain signals sent to the brain). Opan also binds to the norepinephrine receptor, which further enhances its pain-relieving effect. The combination of its opioid and monoamine agonism is responsible for its analgesic effects.

How Long Does It Take To Work?

Opan typically begins to work within 30 minutes to an hour of being taken. The duration of its effects usually last about 4-6 hours. With extended-release tablets, effects may last up to 12 hours.

Absorption

Opan is rapidly and completely absorbed from the gut into the blood stream, with peak blood levels occurring one to two hours after ingestion. It is highly soluble in water, and rapidly distributed throughout the body.

Route Of Elimination

Opan is broken down and eliminated by the liver and kidneys. About 90% of an administered dose is eliminated via the kidneys, and 10% via the bile. It typically takes 4-6 hours for tramadol to be eliminated from the body.

Dosage

Dosage of Opan depends on the task of its use. A starting dose of the medication is usually 25-50mg every four to six hours, for which the maximum dose should not exceed 400mg in a day. For treating breakthrough pain, the dose can be increased to 150-200mg per day. Extended release tablets should be taken once a day, with the maximum dose not exceeding 300mg in a day.

Administration

Opan can be taken orally or administered through an IV. Oral tablets and capsules should be taken with food to reduce the risk of gastrointestinal adverse effects. Oral liquid preparations should be administered with a specifically designed measuring device, and not with a regular teaspoon.

Side Effect

Common side effects of Opan include nausea, vomiting, drowsiness, dizziness, headache, constipation, and dry mouth. Other side effects may include difficulty urinating, loss of appetite, sweating, confusion, and itchy skin. In some cases, more serious side effects such as respiratory depression, hallucinations, and seizures can occur.

Toxicity

Opan is generally considered safe and well-tolerated when used as prescribed. But at higher doses, especially when taken with other medications that also act on the central nervous system, it can be toxic, and may lead to serious respiratory depression, comas, and even death.

Precautions

Opan should be taken with caution, especially in individuals with a history of alcohol abuse or addiction, mental illness, thyroid problems, kidney or liver disease, or a history of convulsions, seizures, or head injury. Opan should not be taken concomitantly with MAO inhibitors, muscle relaxants, sedatives or other narcotic medications.

Interaction

Opan may interact with certain medications such as anticoagulants, antidepressants, monoamine oxidase inhibitors, drugs for high blood pressure, drugs for mental illness, antihistamines, muscle relaxants, and opioids, increasing the risk of toxicity and other side effects.

Disease Interaction

Opan may interact with certain diseases such as seizure disorders, head injury, liver or kidney disease, and respiratory depression, increasing the risk of toxicity and other side effects. Patients with any of these diseases should talk to their doctor before starting tramadol therapy.

Drug Interaction

Opan can interact with several drugs, including alcohol, Monoamine Oxidase inhibitors (MAOIs), anticoagulants, sedatives, muscle relaxants, and opioids. These interactions can increase the risk of toxicity and other side effects. Patients should check with their doctor before starting or stopping any medication while taking tramadol.

Food Interactions

Opan should be taken with food to reduce the risk of gastrointestinal adverse effects. Grapefruit juice should be avoided when taking tramadol, as it can increase the absorption of the drug and potentially increase its toxicity. Certain foods such as aged cheese, red wine, and pickled or smoked meats can also interact with tramadol.

Treatment for an overdose may include administration of naloxone, an opioid antagonist, or other supportive care measures.

Opan is contraindicated in patients who are hypersensitive to it or any of its components. It is also contraindicated in patients who are taking MAO inhibitors, strong CYP3A4 inhibitors, and certain opioid drugs such as meperidine.
