What is a narcotic?

The term narcotic used to refer to a class of drugs that produces pain relief, state of sleep (narcosis), and addiction. Opiates are the most widely known narcotics. This plant–derived substance is extracted from the seeds of opium poppy. Synthetic opioids (fentanyl, methadone) and semi-synthetic opioids (oxycodone, hydrocodone) were later developed to help treat a variety of conditions such as cough, pain, and insomnia, to name a few. Nowadays, narcotics are considered as addictive substances that are controlled by federal law. In medical setting, narcotics are powerful painkillers that are only prescribed for severe pain. They must be used with great caution because of their addictive properties. Common narcotic pain relievers include:

  • Fentanyl patch;
  • Codeine;
  • Morphine;
  • Hydrocodone;
  • Meperidine;
  • Oxycodone;
  • Tramadol.

What is Voltaren used for?

Voltaren is a prescription medication belonging to the arylalkanoic acid class of NSAIDs. Its generic name diclofenac is the 5th most commonly prescribed NSAID in the United States. It is available in different preparations, including tablets for mild to moderate pain and extended release tablets (Voltaren XR) for treating pain, tenderness, swelling, and stiffness caused by osteoarthritis (OA) and rheumatoid arthritis. NSAIDs can relieve pain, inflammation, and fever. Although their mechanism of action has not been fully understood, it typically involves inhibition of the enzymes that facilitates prostaglandin synthesis. In the case of diclofenac, it inhibits both cyclooxygenase 1 and 2 (COX-1 and COX-2) but it has low to moderate inhibitory effects on COX-1. COX-1 inhibitors like aspirin are known to cause side effects on the gastrointestinal (GI) tract, which means diclofenac is associated with a somewhat lower incidence of gastrointestinal complaints.
