Tramadol dosage

Seizures Seizures may be aggravated or may occur in individuals with or without a history of convulsive disorders if dosage is substantially increased above recommended levels because of tolerance. Observe patients with known seizure disorders closely for hydromorphone-, meperidine-, morphine-, or tramadol-induced seizure activity. 

Seizures have been reported in patients receiving tramadol within the recommended dosage range. 

Despite an intensive research effort over the past two decades involving many innovative approaches in the global academic community and by the pharmaceutical industry, the latter representing an aggregate investment in excess of 2.5 billion, the only new opioid-based pain medications either in clinical development or on the market are alternative dosage forms of the classical opioids, morphine, loperamide, and fentanyl, or compounds such as tramadol. ... 

Dosages and routes of administration Tramadol is used in single doses of 50-100 mg up to daily doses of 300-400 mg. The compound has high oral bio-availability and can be given by mouth, rectally or by intramuscular, subcutaneous or slow intravenous injection or infusion (Lintzet al. 1981). 

A purely hydrophilic matrix of hypromellose prolongs the release of tramadol from Tramal long (Fig. 3) developed by Gruenenthal. The tablets have the same dimensions, resulting in an identical release profile for all dosages (100, 150, 200 mg, see Fig. 4). For a titrated effect linear pharmacokinetics on increasing doses produce dose-proportional blood levels at any time. External influences, such as pH value, mechanical stress, surface-active... 

In a randomized, double-blind study in 20 patients with severe postoperative pain given either intravenous tramadol 1 mg/kg or morphine 0.1 mg/kg, both drugs were effective analgesics but higher dosages than those usually administered were necessary (15). Tramadol did not cause any severe adverse effects, but with morphine there was one case each of severe sedation and respiratory depression. 

The role of tramadol in the treatment of rheumatologi-cal pain has been reviewed (33). Tramadol causes fewer opioid adverse effects for a given level of analgesia compared with traditional opioids. Common adverse effects, such as nausea and dizziness, usually occur only at the beginning of therapy, abate with time, and are further minimized by up-titrating the dosage over several days (34). 

Drug dependence During 1995-2006 there were 104 reports of tramadol dependence reported to the Swedish database for adverse drug reactions [195 ]. Important susceptibility factors included a history of substance abuse (in 30%) or documented past or current drug abuse (in 39%). Tramadol dependence occurred in association with the recommended dosage range. 

Tramadol is supphed in 50 mg tablets. Tramadol extended release is supphed in 100 mg, 200 mg, and 300 mg tablets. Tramadol plus acetaminophen is available in a dose of 37.5 mg plus 325 mg of APAP. The recommended dosage is 50-100 mg orally every 4-6 hours as - 39... 

According to the manufacturer s prescribing information, the initial recommended dosage of tramadol ER is 100 mg once daily, with titration in 100 mg increments every 5 days (if required) up to a maximum dosage of 300 mg once daily. The drug is to be used in adults only, and may be administered without regard to food. 

Tramadol ER should be used with caution and in reduced dosages when administered to patients receiving CNS depressants such as alcohol, opioids, anesthetic agents, narcotics, phenothiazines, tranquilizers, antidepressants, or sedative hypnotics. Tramadol ER increases the risk of CNS and respiratory depression in these patients.
