Central nervous system (including peripheral analgesics).

The analgesic drugs can act in many ways on the peripheral or central nervous system, but they do not eliminate the sensation of pain as in the case of anesthetics. Types of Analgesics. Analgesics can be broadly classified into two categories: Non-narcotic (non-addictive) analgesics.

Analgesic drugs act in various ways on the peripheral and central nervous system they include paracetamol and acetylaminophetol also known in the us as acetaaminophen, the NSAIDs such as the acetyl salicylic acid and opiods drugs such as morphine and opium. They are distinct from anesthesia who reversibly eliminate sensation.

Classification of Analgesics Drugs that are included in analgesics work in diverse ways to diminish or relieve pain. They act mainly on the central and peripheral nervous system.

The peripheral and central responses to injury in turn have a major impact on the mechanisms of acute pain. Thus there is an inter-relationship between acute pain and injury and if the injury response is prolonged there can be a negative effect on the outcome.

Classification of Oral Analgesics There are two classes of oral analgesics in general: Non-opioid and opioid analgesics.

Sometimes experts will group analgesics together based on their potency, or how strong they are. An example of this is the World Health Organization’s analgesic ladder. This step-wise approach to pain relief recommends non-opioid analgesics such as acetaminophen and NSAIDs for mild-to-moderate pain; weak opioids, such as codeine.

Peripheral neuropathy is a general term that indicates any disorder of the peripheral nervous system. Since this broad definition includes all varieties and causes of peripheral nerve disease, a meaningful and useful diagnosis needs the definition to be refined.

Peripheral arterial disease (PAD) is characterized by narrowing and, in final stages, occlusion of the peripheral arteries due to atherosclerotic plaques. Smoking is the most important risk factor for developing PAD. PAD is often a silent disease, but patients may present with features of arterial insufficiency ( intermittent claudication.
