This article presents a summary of drug safety data concerning the use of tramadol hydrochloride and an outline of the specific aspects of this analgesic in particular with regard to respiratory depression and dependence potential. Information from phase II to IV clinical studies, postmarketing surveillance studies (covering safety data from a total of more than 21,000 patients) and the spontaneous reporting system have been taken into consideration. The data from the spontaneous reporting system covers the period between 1977 and 1993, during which more than one billion single dose units were distributed throughout the world. ⋯ The adverse effects reported in both clinical and postmarketing surveillance studies are similar to those in the spontaneous reports. The most frequently documented adverse effects in clinical and postmarketing surveillance studies, i.e. nausea/vomiting, dizziness, drowsiness, tiredness, sweating and dry mouth, are noted very infrequently in spontaneous reports, since in medical practice these side effects are usually known and are described in the product information. Almost all reports referring to abuse/dependence are connected with pain therapy; they give no reason to suspect any pro

Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) with strong analgesic activity. The analgesic efficacy of ketorolac has been extensively evaluated in the postoperative setting, in both hospital inpatients and outpatients, and in patients with various other acute pain states. After major abdominal, orthopaedic or gynaecological surgery or ambulatory laparoscopic or gynaecological procedures, ketorolac provides relief from mild to severe pain in the majority of patients and has similar analgesic efficacy to that of standard dosages of morphine and pethidine (meperidine) as well as less frequently used opioids and other NSAIDs. ⋯ In common with other NSAIDs, ketorolac has also been implicated in allergic or hypersensitivity reactions. In summary, ketorolac is a strong analgesic with a tolerability profile which resembles that of other NSAIDs. When used in accordance with current dosage guidelines, this drug provides a useful alternative, or adjuvant, to opioids in patients with moderate to severe pain.

Fentanyl is a synthetic opioid with short-acting analgesic activity after intravenous or subcutaneous administration. The low molecular weight, high potency and lipid solubility of fentanyl make it suitable for delivery via the transdermal therapeutic system (TTS). These systems are designed to release the drug into the skin at a constant rate ranging from 25 to 100 micrograms/h, multiple systems can be applied to achieve higher delivery rates. ⋯ In summary, transdermal fentanyl is a useful alternative to other opioid agents, which are also recommended on the third step of the WHO analgesic ladder, in the management of chronic malignant pain. Preliminary data indicate that it may be useful in the management of chronic nonmalignant pain. The advantages offered by fentanyl TTS over traditional methods of chronic pain control include its ease of administration, less constipation and the 3-

Randomized Controlled Trial Comparative Study Clinical Trial
[Treatment of post-herpes zoster pain with tramadol. Results of an open pilot study versus clomipramine with or without levomepromazine].
To date, no universally applicable recommendations are available for the treatment of patients with postherpetic neuralgia. A mixture of clinical anecdotes, experimental findings and observations from clinical trials form the basis of the medical arsenal for this condition. Tricyclic antidepressants are commonly used, and clinical experience and several investigations have documented their effectiveness. ⋯ In conclusion, tramadol would appear to be an interesting therapeutic alternative for pain relief in postherpetic neuralgia, particularly in patients who are not depressed. In clinical practice, tramadol and clomipramine can best be used differentially. For example, tramadol could be the drug of first choice in patients with obvious cardiovascular disease (not an uncommon problem in the > or = 65 year age group) in whom antidepressants are contraindicated, and similarly in patients in whom an antidepressant effect is not required.

Tramadol has been in clinical use in Germany since the late 1970s and has proven effective in both experimental and clinical pain without causing serious cardiovascular or respiratory side effects. Moreover, the negligible abuse potential of tramadol has meant that it has never been a restricted drug, and it therefore very quickly became the most popular analgesic of its class in Germany. Although tramadol has been used in myocardial emergencies, in trauma and obstetric pain, or to supplement balanced anaesthesia, most studies have investigated postoperative patients. ⋯ In the event of analgesic failure with tramadol, there is no reason not to switch to more potent opioids. Although no studies are available regarding its use in the management of postoperative pain after day case surgery, tramadol is frequently administered with good results in such patients. The most important side effects of tramadol are nausea and emesis, which can often be prevented by slow injection and administration of a prophylactic antiemetic such as metoclopramid
