Aspadol Tablet is a prescription medication that contains Tapentadol as its active ingredient. Medical professionals commonly prescribe Aspadol 150mg for the management of moderate to severe acute and chronic pain. It is known for its dual-action mechanism, offering both opioid and non-opioid pain relief. In this article, we will explore Aspadol in detail — its uses, benefits, dosage, mechanism of action, and potential side effects.
1. What is Aspadol 150mg?
150mg Aspadol is a powerful pain-relief tablet that contains Tapentadol Hydrochloride. Tapentadol is a centrally acting analgesic with dual mechanisms of action — it acts as a mu-opioid receptor agonist and also inhibits the reuptake of norepinephrine. These actions work together to reduce the perception of pain in the brain and spinal cord.
Aspadol is available in various strengths, but the 150mg tablet is typically reserved for more intense or chronic pain conditions when lower doses prove insufficient.
2. How Aspadol Works
Tapentadol, the active ingredient in Aspadol, works through two primary pathways:
-
Mu-opioid receptor agonism: Tapentadol binds to opioid receptors in the central nervous system (CNS), altering the brain’s response to pain.
-
Norepinephrine reuptake inhibition (NRI): By increasing norepinephrine levels, Tapentadol enhances the body’s natural pain-inhibiting mechanisms.
These dual actions make Aspadol a unique analgesic. Unlike traditional opioids that rely solely on mu-receptor binding, Tapentadol’s additional mechanism may improve efficacy while potentially reducing some opioid-related side effects.
3. Medical Uses of Aspadol Tablet
Doctors prescribe 150mg Aspadol to manage several pain-related conditions. Common uses include:
a. Acute Pain
Aspadol effectively treats pain that comes on suddenly and is often intense. Examples include:
-
Post-operative pain
-
Injury-related pain
-
Pain from dental surgery
b. Chronic Pain
Chronic pain persists for more than 3 to 6 months. Aspadol can be prescribed for:
-
Lower back pain
-
Neuropathic pain (especially diabetic peripheral neuropathy)
-
Osteoarthritis pain
-
Fibromyalgia (off-label)
c. Cancer-Related Pain
Patients undergoing cancer treatment often experience persistent and severe pain. Aspadol helps manage such pain when non-opioid treatments are inadequate.
4. Dosage and Administration
150mg aspadol should be taken strictly as prescribed. Because of its potency, doctors generally follow a step-up approach—starting with lower doses (50mg or 100mg) and increasing to 150mg only when necessary.
Typical Dosage Guidelines:
-
Adults: One 150mg tablet every 12 hours
-
Maximum Daily Dose: Should not exceed 600mg per day unless advised by a physician
-
Administration: Swallow the tablet whole with water; do not crush or chew
aspadol tablet is usually reserved for patients who are opioid-tolerant or those with severe chronic pain.
5. Benefits of Aspadol Tablet
Patients and healthcare providers choose Aspadol for several key benefits:
-
Fast-acting: It begins to relieve pain within 30–60 minutes
-
Dual-action mechanism: Combines opioid and non-opioid effects for broader pain control
-
Improved tolerance: May cause less nausea and constipation compared to older opioids like morphine
-
Effective for neuropathic pain: Particularly helpful in diabetic neuropathy

8. Drug Interactions
150mg aspadol can interact with other medications, potentially increasing side effects or reducing efficacy.
Avoid Combining With:
-
Other opioids: Increases risk of respiratory depression
-
MAO inhibitors (e.g., phenelzine, isocarboxazid): Can cause dangerous reactions
-
SSRIs/SNRIs (e.g., fluoxetine, duloxetine): May increase risk of serotonin syndrome
-
Alcohol or sedatives: Enhances drowsiness and respiratory risk
-
Antipsychotics: Can lead to CNS depression
Always inform your doctor about all the medications you are taking, including over-the-counter drugs and supplements.
9. Dependence, Tolerance, and Withdrawal
Tapentadol is a Schedule II controlled substance in many countries, including the U.S., due to its potential for abuse, addiction, and dependence.
Dependence and Tolerance:
-
The body can become tolerant to Aspadol with long-term use.
-
Higher doses may be required over time to achieve the same level of pain relief.
Withdrawal Symptoms:
Stopping Aspadol abruptly may cause withdrawal. Symptoms include:
-
Sweating
-
Restlessness
-
Insomnia
-
Anxiety
-
Body aches
-
Nausea and vomiting
To avoid withdrawal, doctors usually taper the dose gradually.
10. Storage and Handling
-
Storage: Keep at room temperature (20–25°C), away from moisture and heat.
-
Keep out of reach of children and pets
-
Do not share: Prescription opioids should never be shared with others, especially those with a history of substance misuse.
11. Alternatives to Aspadol
If Aspadol tablet is not suitable or causes unwanted effects, doctors may recommend alternatives, such as:
-
Tramadol: Weaker opioid with a similar dual mechanism
-
Oxycodone or Morphine: Stronger opioids without NRI action
-
Pregabalin or Gabapentin: Especially for neuropathic pain
-
NSAIDs: Like diclofenac or ibuprofen for milder pain
Always consult a healthcare provider before switching medications.
