An analgesic is a pain relieving substance. It does not cure the problem that causes the pain, but reduces the feeling of the pain.
Conventional analgesics are classified as opioids and nonopioids, but the older terms ‘‘narcotic’’ and ‘‘non-narcotic’’ continue to be used interchangeably. Current researches have shown that both classes have varying degrees of central and peripheral action. The primary feature that distinguishes these 2 classes of analgesics is their mechanisms of action. Nonopioids include acetaminophen and the nonsteroidal anti-inflammatory drugs (NSAIDs). Opioids are represented by morphine. It is rational for the practitioner to combine drugs from these classes when managing moderate to severe pain. To select combination regimens wisely, it is necessary to understand the significant pharmacological features of each category alone.
Analgesics are used as short term measures to ease pain before, during and after dental treatment. Some dental procedures can result in pain and discomfort after treatment. Pain relievers play a part in making the treatment more comfortable. An analgesic taken before a dental appointment can relieve minor discomfort or stress.
Severe dental pain is usually caused by the inflammation of the nerves and blood vessels in and around the tooth. This is usually associated with tooth decay.
Inflammation is the cause of most dental pain. Anti-inflammatory drugs are effective against such pain. Aspirin and Ibuprofen are anti-inflammatory in their action.
The most commonly used analgesics are:
Ø Acetaminophen, also known as Paracetamol or Tylenol
Ø Aspirin
Ø Codeine
Ø Ibuprofen
Acetaminophen or Paracetamol:
| · It reduces pain and fevers. · It has no blood-thinning side effects. · It does not cause gastric irritation. · Children from two months of age can be given a liquid preparation. · There is an appropriate dose for all age groups. |
