Treatment of moderate and severe pain includes the use of tramadol, an opioid analgesic, that binds to opioid receptors in the brain and spinal cord. The drug inhibits the transmission of pain signals, offering pain relief. A common question among individuals on the medication is – how long does it take for tramadol to start working? Following sub sections offer a detailed look at the medication, including answers to the above question. This is intended to help patients manage pain more effectively, in addition to mitigating possible undesirable effects.
Overview of Tramadol
Tramadol is available in various oral formulations, including immediate-release and extended-release tablets, apart from oral solution. Misuse or abuse of tramadol may trigger serious side effects, including respiratory depression, dependence, and possible withdrawal symptoms. By virtue of its potential for abuse, it is classified as a controlled substance in certain countries. The prescription medication is used to treat various conditions, including the following:
- Acute pain – The drug manages pain experienced post-surgical procedures, injuries, or other acute pain conditions.
- Chronic pain – Tramadol is also considered as effective in treating chronic pain conditions including osteoarthritis, fibromyalgia, and neuropathic pain.
- Cancer pain – The drug is also part of multimodal pain management regimen for cancer patients, to relieve pain associated with cancer and its treatments.
- Dental pain – Tramadol is effective in offering relief from dental pain, typically experienced after tooth extraction or oral surgery.
Mechanism of action of tramadol
The exact mechanism of action of tramadol is complex and not fully established. Tramadol is a centrally acting analgesic, working in the central nervous system to provide pain relief. The primary mechanism of action of tramadol is believed to be a result of its dual action on opioid and non-opioid receptors in the CNS. Tramadol binds to mu-opioid receptors in the brain, responsible for mediating the analgesic effects of opioids. This binding action results in the inhibition of pain transmission and the reduction of pain perception. The drug’s affinity for mu-opioid receptors is relatively weak compared to other opioids, and this makes it a weak opioid agonist.
In addition to the drug’s opioid activity, tramadol also inhibits the reuptake of norepinephrine and serotonin in the CNS. Consequently, this brings about an increase in the levels of the neurotransmitters, with enhanced inhibitory effects on pain transmission pathways in the spinal cord and brain. This dual mechanism of action, involving both opioid receptor activation and modulation of norepinephrine and serotonin reuptake, delivers the analgesic effects.
How long does it take for tramadol to start working?
The onset of action of tramadol depends on the formulation and manner of administration. Oral formulations such as immediate-release tablets are typically absorbed relatively quickly and may deliver outcomes within 30 to 60 minutes. However, the full analgesic effect may take longer to manifest. The peak effect of oral tramadol typically occurs within 1 to 2 hours after administration.
Extended-release formulations of tramadol, such as tramadol ER tablets, are intended to provide prolonged pain relief over an extended period of time. These formulations are usually taken once or twice daily, and their onset of action may be delayed compared to immediate-release tramadol. It may take several hours for tramadol ER to start working, and the peak effect may occur later, typically within 4 to 6 hours after administration.
The onset of pain relief may vary from person to person and may depend on various factors, including the individual’s metabolism, tolerance, and the severity of pain being treated.
Different forms of tramadol
As outlined earlier, Tramadol is available in different forms, including the following:
- Immediate-release tablets and capsules: Commonly prescribed forms of tramadol, these formulations are typically taken orally and provide immediate pain relief. Immediate-release tramadol is available in various strengths, including 50 mg, 100 mg, or 200 mg.
- Extended-release tablets and capsules: Designed to provide prolonged pain relief over an extended period of time, these formulations are typically taken once or twice daily, depending on the specific product. Extended-release formulations are available in strengths including 100 mg, 200 mg, 300 mg, or higher.
- Tramadol injection: The drug may also be administered via intravenous or intramuscular injection in certain conditions, including hospital settings or for patients unable to intake oral medications. Tramadol injection is typically used for short-term pain relief in acute situations.
- Tramadol oral disintegrating tablets: This refers to tablets that dissolve quickly in the mouth without the need for water. They are known to be a convenient option for patients with difficulty swallowing tablets or capsules.
- Tramadol combination products: The drug is often combined with other medications to offer synergistic pain relief. For instance, tramadol/acetaminophen combination products are available for enhanced pain relief.
Specific formulations and strengths of tramadol are often different in countries and are subject to local regulations and availability. The appropriate form and strength of tramadol for a particular individual depends on various factors, including the severity of pain and the patient’s medical condition.
How long do the effects of tramadol last?
The duration of effects of tramadol vary depending on various factors, including the individual’s metabolism, dose, and formulation of tramadol, as well as the severity of pain being treated. In general, the effects of immediate-release tramadol typically last for about 4-6 hours, while the effects of extended-release tramadol can last for up to 12-24 hours.
Upon being orally administered, tramadol is rapidly absorbed from the gastrointestinal tract and reaches peak plasma concentrations within 1-2 hours for immediate-release tramadol, and within 4-5 hours for extended-release tramadol. The onset of analgesic effects usually occurs within 30-60 minutes for immediate-release tramadol and may be delayed for extended-release tramadol due to its slower absorption.
The outcomes of the drug on individuals may differ, with the duration of effects influenced by factors such as the patient’s age, kidney or liver function, and other medications in use, apart from the severity of pain. All patients are to follow dosage instructions of the healthcare provider and the dosage is not to exceed the maximum permitted recommended dosage or duration of use.
