A new administration form of Tramadol ( Generic Ultram ) (50 mg) was compared in a multicenter double-blind trial with pentazocine (50 mg) and with placebo in patients with acute pains. Each patient received a test preparation once. The preparations were available in identical capsules. During the five-hour observation period the effect on the intensity of pain was recorded with reference to a scale and the undesirable side effects noted. Tramadol ( Generic Ultram ) was shown to have an analgesic effect about equal to that of the comparative preparation. Both analgesics were superior in effect to the placebo, as was expected. The incidence of side effects from Tramadol ( Generic Ultram ) was less than that with the comparative substance, even if both analgesics had a higher incidence of side effects than the placebo. The results confirm earlier experience obtained with parenteral application of Tramadol ( Generic Ultram ).
 A clinical-experimental study of narcotic properties of opiate receptor agonists-antagonists and experience in their use in drug addiction practice Narcogenic characteristics of opiate agonists-antagonists were studied in drug abusers. It is shown that buprenorphine, butorphanol, nalbuphine hydrochloride, but not Tramadol ( Generic Ultram ), have high narcogenic potential. Opportunities for these drugs in narcological practice are outlined.
 Effects of Tramadol ( Generic Ultram ) on alpha2-adrenergic receptors in the rat brain.Faron-Gorecka A, Kusmider M, Inan SY, Siwanowicz J, Dziedzicka-Wasylewska M.Institute of Pharmacology, Polish Academy of Sciences, 12 Smetna Street, Cracow PL-31-343, Poland.In recent years, it has been postulated that Tramadol ( Generic Ultram ), used mainly for the treatment of moderate to severe pain, might display a potential as an antidepressant drug. The present study investigated the effects of acute and repeated Tramadol ( Generic Ultram ) administration on the binding of [3H]RX 821002, a selective alpha2-adrenergic receptor ligand, in the rat brain. Male Wistar rats were used. Tramadol ( Generic Ultram ) (20 mg/kg, i.p.) administered acutely (single dose), at 24 h after dosing, induced a significant decrease in the alpha2-adrenergic receptors in all brain regions studied. The most pronounced effects were observed in all subregions of the olfactory system, nucleus accumbens and septum, thalamus, hypothalamus, amygdala, and cerebral cortex. Repeated treatment with Tramadol ( Generic Ultram ) (20 mg/kg, i.p., once daily for 21 days) also induced statistically significant downregulation of [3H]RX 821002 binding sites in the rat brain. However, the effect--although statistically significant--was less pronounced than in the group treated acutely with the drug. Since drugs such as mianserin and mirtazapine are potent antagonists of central alpha2-adrenergic receptors and are effective antidepressants, it is tempting to suggest that, in addition to other alterations induced by Tramadol ( Generic Ultram ), downregulation of these receptors may represent a potential antidepressant efficacy. On the other hand, one should be careful to avoid the treatment of chronic pain with Tramadol ( Generic Ultram ) in patients already receiving antidepressant drugs. Tramadol ( Generic Ultram )-induced downregulation of alpha2-adrenergic receptors--when combined with ongoing antidepressant therapy with drugs, which themselves inhibit serotonin reuptake or are antagonists of alpha2-adrenergic receptors--might cause threatening complications.
 Development of electrochemical methods for determination of Tramadol ( Generic Ultram )--analytical application to pharmaceutical dosage forms. OBJECTIVE: To assess the analgesic effect and side effects of PCA with lornoxicam compared with morphine and Tramadol ( Generic Ultram ). METHODS: 89 patients, scheduled for elective hysterectomy or hysteromyomectomy, were randomly divided into Group L, Group M and Group T. Three drugs administered i.v. via a patient-controlled analgesia for up to 24 h postoperatively. RESULTS: Efficacy was assessed by comparing total pain relief (TOTPAR) and sum of pain intensity difference (SPID) over 24 h. Statistically significant equivalence of lornoxicam, morphine and Tramadol ( Generic Ultram ) was shown by TOTPAR values 15.2 +/- 3.9, 16.4 +/- 3.5 and 15.9 +/- 4.4, by SPID values 10.3 +/- 3.1, 9.0 +/- 2.0 and 9.2 +/- 4.7, respectively (P > 0.05). Lornoxicam caused fewer adverse events than morphine and Tramadol ( Generic Ultram ) (10.0%, 26.7% and 17.2% of patients, respectively). CONCLUSION: The study suggests that lornoxicam provides an alternative to morphine or tramadaol for the treatment of postoperative pain.

 Synthesis and analgesic activity of some quinazoline analogs of anpirtoline. New condensed derivatives of anpirtoline, in which the pyridine ring is replaced with quinoline, quinazoline, 7-chloroquinoline, and 7-chloroquinazoline nuclei, have been synthesized. Their receptor binding profiles (5-HT1A, 5-HT1B) and analgesic activity (hot plate, acetic acid induced writhing) have been studied. The analgesic activity of compounds 4e-4g, and 4l are at least comparable to that of clinically used drugs flupirtine and Tramadol ( Generic Ultram ) under the same conditions.
 Ketoprofen (ketonal): a drug for preventing and treating postoperative pain An inert matrix to control the release of Tramadol ( Generic Ultram ) HCl was prepared using glyceryl behenate as a matrix-forming agent. The matrices were prepared by either direct compression of a physical mixture of the drug and the matrix-forming agent or by compression of granules prepared by hot fusion of the drug and the matrix-forming agent. The hot fusion method was found to be more effective than compression of physical mixtures in retarding the release of the drug from the matrix. Drug release was adjusted by using release enhancers, such as microcrystalline cellulose and lactose, and the results showed that higher release rates were obtained using lactose. However, the release of the drug was independent of the compression force and the pH of the dissolution medium. This study showed that glyceryl behenate is an appropriate waxy material that can be used as a matrix-forming agent to control the release of a water-soluble drug such as Tramadol ( Generic Ultram ) HCl.
 Synthesis and CNS-activity of spirocyclic pethidine and prodine analogs The bromoacetals 5a and 5b react with n-butyllithium and the piperidone 7 to yield the hydroxyacetals 8b and 8c, respectively. Cyclization of 8b and 8c followed by acid hydrolysis affords the spirocyclic hemiacetals 10b and 10c which are oxidized by PCC to give the spirocyclic prodine analogues 4b and 4c. The corresponding spirocyclic pethidine derivative 2 is prepared by alkylation of the 2-benzopyran-3-one 16 with N-Lost (17). In the mouse writhing test the spiropethidine 2 is not analgesic active up to a dose of 20 mg/kg body weight (bw). In the spirocyclic prodine series the methylated lactone 4c is the most active analgesic with an ED50-value (ED50 = 9.2 mg/kg bw) in the range of the ED50-value of Tramadol ( Generic Ultram ).
 Involvement of potassium channels and nitric oxide in Tramadol ( Generic Ultram ) antinociception. It has been considered that Tramadol ( Generic Ultram ), a centrally acting analgesic, shows its effect via opiatergic, noradrenergic, and serotonergic systems. It has a low affinity for opioid receptors, and its effect can be partly blocked by naloxone. Since the noradrenergic and serotonergic mechanisms are still unknown, other systems which are associated with pain and analgesia may have a role on the antinociceptive effect of Tramadol ( Generic Ultram ). The aim of this study was to evaluate the effects of K(+) channels and nitrergic systems on the antinociceptive action of Tramadol ( Generic Ultram ). The antinociceptive effects of Tramadol ( Generic Ultram ) were determined in mice by the hot plate test. To examine the effects of K(+) channels and the nitrergic system nonspecific voltage-dependent K(+) channel blockers 4-aminopyridine (4-AP) and tetraethylammonium (TEA), nitric oxide (NO) precursor l-arginine, and the NO synthase (NOS) inhibitor N(G)-nitro-l-arginine methyl ester (l-NAME) were used. Our results indicated that 4-AP, TEA, and l-arginine reduced the antinociceptive effect of Tramadol ( Generic Ultram
