Physicians chiefly often recommend or prescribe oral medication for relief of acute pain. This review of the available evidence supports the use of acetaminophen in doses up to 1000 mg as the initial choice for mild to moderate acute pain. In more [i]or[/i] less cases, modest improvements in analgesic efficacy can be achieved by means of adding or changing to a nonsteroidal anti-inflammatory put drugs into (NSAID). The safest NSAID is ibuprofen in doses of 400 mg Higher doses may furnish somewhat greater analgesia but with more adverse validitys Other NSAIDs have failed to demonstrate consistently greater efficacy or safety than ibuprofen. Although they may be more expensive, these alternatives may be chosen for their more convenient dosing. Cyclooxygenase-2 inhibitors provide equivalent efficacy to traditional NSAIDs still lack a demonstrable safety advantage for the treatment of acute pain. For more stiff acute pain, the evidence supports the addition of oral narcotic medications like as hydrocodone, morphine, or oxycodone. Specific oral analgesics that have shown poor efficacy and side powers include codeine, propoxyphene, and tramadol.

**********

Approximately individual half of the population reports pain or discomfort that persists continuously or intermittently for longer than three month An steady greater number of persons are likely to have acute pain at any the same time. (1) Unfortunately, considerable confusion exists about the efficacy and safety of commonly used analgesics. This review provides a take a view of of the best available evidence regarding oral analgesia for acute pain, which is defined as pain associated with just discovered tissue injury that typically lasts les than the same month, but at times for as drawn out as six months. (2) Acute pain generally does not involve the long-term daily use of analgesics.

Search Strategy

a great quantity [i]or[/i] amount of of the literature on oral analgesics defines the efficacy of a specific analgesic as the proportion of patients who ne to take that analgesic to experience at least a 50 percent reduction in pain compared with placebo. The universal of number needed to treat (NNT) is a particularly helpful way to demise this outcome. It refers to the number of patients who have to use the treatment for the same patient to benefit. For example, when acetaminophen is said to have an NNT of four compared with placebo, it means that for each four patients who take acetaminophen instead of placebo, at least undivided patient will experience a 50 percent decrease in pain. The other three patients may have a significant decrease in pain (eg 40 or 30 percent) nevertheless this is not reflected in the NNT The lower the NNT the greater the likelihood that a given patient will achieve a 50 percent reduction in pain. (3) Other measures of pain relief include average decreases forward visual analog scales and functional issue measures. A visual analog scale is a 100-mm line with no pain at united end and severe pain at the other. For meaningful analgesia of acute pain, patients must report at least a 13-mm difference between analgesic choices. (45)

This review focuses upon the most commonly used oral analgesics for acute pain available in the United States: acetaminophen, nonsteroidal anti-inflammatory remedys (NSAIDs), cyclooxygenase-2 (COX-2) inhibitors, tramadol (Ultram), and opiates.

Acetaminophen

Acetaminophen is a unique analgesic without a clearly defined mechanism. In a meta-analysis of 40 trials involving 4171 patients comparing acetaminophen with placebo for postoperative pain, acetaminophen in a dose of 1000 mg had an NNT of 46 (95 percent confidence interval [CI], 38 to 54) for at least 50 percent pain relief versus placebo. Lower doses were les effective. (6)

Direct comparative studies between acetaminophen (1000-mg dose) and NSAIDs exhibit that NSAIDs are more effective than acetaminophen in one situations (e.g., dental and menstrual pain), yet provide equivalent analgesia in others (eg orthopedic surgery and tension headache). (78)

Aspirin

Aspirin is an effective analgesic for acute pain, yet it has not proved more effective than equal doses of acetaminophen. It also has a worse safety profile than acetaminophen. (9)

Traditional NSAIDs

EFFICACY

NSAIDs are extremely good analgesics with no clinically important difference in efficacy among specific medicines (10) They are superior to acetaminophen for a certain types of pain, and in many acute pain settings they provide analgesia equal to usual starting doses of narcotics. (11) However, unlike narcotics that lack a ceiling dose, NSAIDs have a maximum dose above which no additional analgesia is obtained. Higher doses of NSAIDs may be used for anti-inflammatory meanings However, this review focuses merely on doses used for analgesia.

sturdy evidence supports the use of nonprescription NSAIDs for dysmenorrhea and acute postpartum pain. In a meta-analysis (12) of randomized controll trials (RCTs) of analgesics for dysmenorrhea, ibuprofen (Motrin) and naproxen (Aleve, Naprosyn) were equally effective, and the two were better than acetaminophen and aspirin. For dysmenorrhea, acetaminophen was no better than placebo. no other than naproxen had side effects worse than those of placebo. (12) Ibuprofen has shown similar effectiveness to a combination of acetaminophen, codeine, and caffeine for postpartum perineal pain with fewer side validitys (13)
