Tramadol is an opioid analgesic used for the treatment of moderate to severe pain. It affects the central nervous system by blocking pain signals sent to the brain and altering the perception of pain. Tramadol binds to opioid receptors in the brain and spinal cord, leading to a reduction in pain sensations. Additionally, it inhibits the reuptake of serotonin and norepinephrine, enhancing its analgesic effect.
Tramadol acts by activating mu-opioid receptors, which alters the perception of pain in the central nervous system. Besides this, tramadol inhibits the reuptake of serotonin and norepinephrine, further contributing to its analgesic effect. This combined action makes tramadol effective for treating various types of pain, including chronic and acute pain.
Tramadol is often used to relieve pain in patients with chronic conditions such as arthritis or cancer. It may also be prescribed after surgical interventions or injuries to reduce pain during the recovery period. Tramadol can be used in the treatment of neuropathic pain when other analgesics are ineffective.
Indications
Tramadol is indicated for the management of moderate to moderately severe pain in adults. It is commonly prescribed for conditions such as:

Dosage and Administration
The dose of tramadol is selected individually depending on the severity of pain and the patient's response to the drug. The usual starting dose is 50-100 mg, which can be repeated every 4-6 hours if necessary. The maximum daily dose should not exceed 400 mg. Treatment should start with low doses and gradually increase to avoid side effects. The treatment should be discontinued gradually to prevent withdrawal symptoms.
Tramadol is available in various forms, including tablets, capsules, injection solutions, and suppositories. This allows for the selection of the most appropriate form for the specific patient and clinical situation.
Side Effects
Common side effects include nausea, dizziness, constipation, headache, drowsiness, and dry mouth. More serious side effects may include seizures, difficulty breathing, and allergic reactions. Long-term use may lead to dependence and withdrawal syndrome.
Patients may experience dizziness and drowsiness, requiring caution when driving vehicles and operating machinery. Some patients may experience mood changes, including depression and anxiety.
Drug Interactions
Tramadol can interact with various drugs, enhancing or weakening their effects. Special care should be taken when using tramadol with other opioids, antidepressants, antipsychotics, and sedatives. These interactions can lead to increased side effects, including the risk of seizures and serotonin syndrome.
Special Precautions
Tramadol should be used with caution and only under the supervision of a physician to minimize the risk of side effects and dependence. Special attention should be paid to patients with a history of drug dependence, as tramadol can trigger a relapse. During long-term use, it is necessary to periodically assess the need for continued treatment and adjust the dosage accordingly.
Tramadol is not recommended for use in children under 12 years of age, as well as in pregnant and breastfeeding women, except in cases where the potential benefit outweighs the possible risks.
