Background: Pain is an unpleasant sensation that can range from mild, localized discomfort to agony. The mechanism of pain perception involves dedicated subsets of peripheral and central neurons. For management of pain, currently, available treatment regimens are opioid analgesics and NSAIDs which are easily available over the counter drugs. Long term use of analgesics can lead to significant impact on human renal system, cardiovascular system and analgesic abuse etc. So, there is a need for novel, safe and cost-effective analgesic compound. Hence a study on 2-4 methylphenylimino-3-carboxamide substituted thiophene compound, a novel thiophene compound has been carried out in different experimental animal models.Methods: Two methods were used to evaluate the central analgesic activity of 2-4 methylphenylimino-3-carboxamide substituted thiophene compound. First method was Eddy’s hot plate method and compared to standard central analgesic, morphine. Second method was early phase of formalin induced paw licking in mice and compared to a standard drug, aspirin.Results: With eddy’s hot plate method, 40mg/kg dose of 2-4 methylphenylimino-3-carboxamide substituted thiophene compound has shown maximum pain inhibition percentage (PIP) of 45% at 60 min compared to 125% by morphine. Whereas with early phase of formalin test, 40 mg/kg dose of 2-4 methylphenylimino-3-carboxamide substituted thiophene compound has shown maximum PIP of 44% in early phase compared to 60% by aspirin. The results were statistically significant with p<0.05.Conclusions: It can be concluded that 2-4 methylphenylimino-3-carboxamide substituted thiophene compound found to have minimal central analgesic activity as evident in eddy’s hot plate and early phase of formalin tests.

AbstractDriedChloroform extract showed significant (p<0.05) analgesic effect at the doses of 75, 150 and 300 mg/kg in hot plate and tail flick tests. Methanol extract showed significant (p<0.05) analgesic effect at the dose of 300 mg/kg in hot plate and tail flick tests. Analgesic activity was not blocked (p<0.05) in the group pretreated with phentolamine but blocked in the groups pretreated with naloxone andThe chloroform extract was found to be more potent than methanol extract in inducing analgesic effect in mice, and the analgesic activity may be mediated through opioidergic and serotonergic pathways.

Important Medicinal Plant

Objective: Plumeria alba (Apocynaceae), commonly known as “Frangipani” is an important medicinal plant, widely distributed throughout Southern India. In the traditional medicinal system, different parts of this plant have been mentioned to be useful in a wide variety of diseases. In this study, analgesic activity of aqueous and alcoholic extract of flowers of P. alba Linn was evaluated by hot-plate and acetic acid-induced writhing methods to substantiate and expand its clinical applications. Methods: The flowers of P. alba were collected from the local area in and around Coimbatore (India). The flowers were dried, powdered, and were extracted using soxhlet apparatus for 12 h using water and 95% of ethanol as a solvent. The test extracts were administered orally at a dose of 100 & 200 mg/kg while diclofenac sodium (10 mg/kg) served as standard. Results: The ethanolic flower extract of 200 mg/kg had significant analgesic activity in acetic acid-induced abdominal writhing response (***p<0.001) when compared to control and standard drug diclofenac. It also exhibited significant analgesic activity (***p<0.001) by increasing the pain reaction time of the rats in comparison to control and standard in hot plate method. Conclusion: The results suggest that ethanolic flower extracts of P. alba possess potent analgesic properties, which support its use in traditional medicine and suggesting that the plant should be further investigated for its pharmacological active natural products.

Background: The objective of the study was to evaluate analgesic activity of ethanolic extract, methanol and benzene fraction of Myristica fragrans on wistar albino rats.Methods: The present study was carried out in the department of pharmacology JNMC AMU and F.H. Medical College, Agra. The analgesic activity was evaluated by employing the Eddy’s hot plate method and tail flick response method. In both the tests, Rats of either sex weighing 150-200 g were used. The total number of animals n=36 were allocated to six groups. Each group consist of six animals each. The response noted in animals that were tested by hot plate method was reaction time for licking/biting of both the paws before and after administration of control & test drugs. However in Tail flick test, the pain threshold response was recorded before and after administration of control & test drugs. The statistical analysis was done by using one-way ANOVA. The data is expressed as Mean±SEM. P<0.05 was considered to be statistically significant.Results: Ethanolic extracts and methanol fraction of M. fragrans showed statistically significant (p<0.001) increase in reaction time for licking/biting in hot plate method. On the contrary a significant increase in pain threshold was also recorded in tail flick response test. It is interesting to note that no significant degree of analgesia related to any dose of benzene fraction was observed.Conclusions: The present study reveals the dose dependent significant analgesic activity of the extracts of M. fragrans i.e. ethanolic extracts and methanol fraction in both the test. However, the degree of analgesia was recorded significantly higher in groups received higher doses of extracts of M. fragrans.

Background: Pain is a very well-known symptom of many diseases and analgesics are used to relieve pain. The main problem with these drugs remains that of side effects. Herbal medicines are better in view of their cultural acceptability, better compatibility with human body systems and lesser incidence of side effects. Extract of Tinospora cordifolia (Guduchi) plant have been traditionally used to treat pain in traditional medicine.Methods: Commercially available preparation of T. cordifolia plant has been used as test drug (aqueous extract). Healthy albino rats of either sex, weighing between 140-200 g were selected for the study, divided into 4 groups of 6 each (control, standard, 100 mg/kg, 300 mg/kg). Central analgesic activity was assessed by tail flick model (morphine as standard drug I.P). Acetic acid 1% 10 ml/kg aqueous solution I.P. was used for abdominal writhing model. Diclofenac 150 mg/kg oral as standard drug for assessment of peripheral analgesic activity. Results were analysed using SPSS version 16 and Microsoft office excel 2007.Results: T. cordifolia extract significantly increased the tail flick latency time (sec) (mean tail flick latency control, T100, T300 6.833±0.25 sec, 8.65±017 sec, 10.01±0.14 respectively) (p value control vs T100, T300 at 90 min, 120 min, 0.0573, 0.0198, 0.0198 in between group) and decreased number of abdominal writhing in comparison with the control group (p value <0.0001).Conclusions: Extract of T. cordifolia was found to possess analgesic activity and also exhibited dose and time dependant increase involving central and peripheral mechanisms. The analgesic activity of T. cordifolia found to be comparable to standard drug used.
