Evaluation of Analgesic and Anti-Inflammatory Activities on Ethanolic Extract of <i>Terminalia chebula</i>Fruits in Experimental Animal Models

The present study was undertaken to evaluate the analgesic and anti-inflammatory activities of ethanolic extract of Terminalia chebula (commonly known as Haritaki) fruits in experimental animal models. The study was carried out using Swiss Albino mice (20-25 g) and Long Evans rats (100-150 g) of either sex. The analgesic activity of Terminalia chebula was assessed by using hot plate method. For the determination of analgesic effect, doses of ethanolic extract of Terminalia chebula used in the present study were 250 mg/kg and 500 mg/kg body weight (BW). Anti-inflammatory effect was analyzed by carrageenan induced paw edema method with the administration dose of 300 mg/kg BW of animals. The analysis of experimental data was performed by statistical process of ANOVA to determine the variability of sample, while Dunnet’s test was performed for evaluation of comparative analgesic and anti-inflammatory activity of Terminalia chebula with control and standard. The animals were divided into four treatment groups of six animals each and the “Mean ± SEM” is the statistical identifiable value of the data and P values <0.05 was considered statistically significant. Hot plate test showed a significant increase in the mean reaction time to heat stimuli in hot plate method at both 250 mg/kg and 500 mg/kg BW doses throughout the observation period in 30 minutes and 60 minutes after treatment, which was comparable to the standard ketorolac and control group. In carrageenan induced paw edema method, considerable results were found after determining the percentage change in paw volume in extract. In both cases of analgesic and anti-inflammatory study, % inhibition of pain and inflammation were evaluated. Comparing with control, largest inhibition was found in inhibiting inflammation 5 hours after treatment, while the largest inhibition of pain was obtained in 30 minutes and 60 minutes after treatment of doses. The present study suggests that ethanolic extract of Terminalia chebula fruits has significant analgesic and anti-inflammatory activities.

Design and Synthesis of Some Enaminonitrile Derivatives of Antipyrine as Potential Novel Anti-Inflammatory and Analgesic Agents

The starting (1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)carbon-hydrazonoyl dicyanide (2) was used as a key intermediate for the syntheses of novel acyclic enaminonitriles 3-10. The newly synthesized compounds were characterized by elemental analyses and spectral data (IR, 1H NMR, 13C NMR and mass spectra). The anti-inflammatory activity data indicated that many of tested compounds protected rats from carrageenan-induced inflammation, and tested compounds 3, 4, 9 and 10 were the most potent among tested compounds. The analgesic activity was determined by the hot plate test (central analgesic activity) and acetic acid induced writhing assay. The results revealed that compounds 3, 4, 9, and 10 exhibited significant activity. However, compound 10 proved to have better or equivalent activities in comparison to the reference drug.

Benzimidazole derivatives: search for GI-friendly anti-inflammatory analgesic agents

Non-steroidal anti-inflammatory drugs(NSAIDs) have been successfully used for the alleviation of pain and inflammation in the past and continue to be used daily by millions of patients worldwide. However, gastrointestinal(GI) toxicity associated with NSAIDs is an important medical and socioeconomic problem. Local generation of various reactive oxygen species plays a significant role in the formation of gastric ulceration associated with NSAIDs therapy. Co-medication of antioxidants along with NSAIDs has been found to be beneficial in the prevention of GI injury. This paper describes the synthesis and biological evaluation of N-1-(phenylsulfonyl)-2-methylamino-substituted-1H-benzimidazole derivatives as anti-inflammatory analgesic agents with lower GI toxicity. Studies in vitro and in vivo demonstrated that the antioxidant activity of the test compounds decreased GI toxicity.

Quasi-Static, Poiseuille Flow of Analgesics from an Elastomeric Pump: Theoretical Determination of Infusion Times and Toxicity Conditions

Background: Elastomeric pumps (elastic balls into which analgesics or antibiotics can be inserted) push medicines through a catheter to a nerve or blood vessel. Since elastomeric pumps are small and need no power source, they fit easily into a pocket during infusion, allowing patient mobility. Elastomeric pumps are widely used and widely studied experimentally, but they have well-known problems, such as maintaining reliable flow rates and avoiding toxicity or other peak-and-trough effects. Objectives: Our research objective is to develop a realistic theoretical model of an elastomeric pump, analyze its flow rates, determine its toxicity conditions, and otherwise improve its operation. We believe this is the first such theoretical model of an elastomeric pump consisting of an elastic, medicine-filled ball attached to a horizontal catheter. Method: Our method is to model the system as a quasi-Poiseuille flow driven by the pressure drop generated by the elastic sphere. We construct an engineering model of the pressure exerted by an elastic sphere and match it to a solution of the one-dimensional radial Navier-Stokes equation that describes flow through a horizontal, cylindrical tube. Results: Our results are that the model accurately reproduces flow rates obtained in clinical studies. We also discover that the flow rate has an unavoidable maximum, which we call the “toxicity bump”, when the radius of the sphere approaches its terminal, unstretched value—an effect that has been observed experimentally. Conclusions: We conclude that by choosing the properties of an elastomeric pump, the toxicity bump can be restricted to less than 10% of the earlier, relatively constant flow rate. Our model also produces a relation between the length of time that the analgesic fluid infuses and the physical properties of the fluid, of the elastomeric sphere and the tube, and of the blood vessel into which the analgesic infuses. From these, we conclude that elastomeric pumps can be designed, using our simple model, to control infusion times while avoiding toxicity effects.
