Abstract

The present study was designed to evaluate the analgesic and anti-inflammatory activity of "Trichilia connaroides" bark using different animal models. Analgesic activity was evaluated by using various two animal models namely, Writing Test using acetic acid in mice and Hot Plate Method. The degree of analgesic activity was determined by the number of wriths was recorded for each animal in Writing Test using acetic acid in mice model and the delay in reaction time for of each animal when place in hot plate maintained at 55±0.10c is recorded in Hot Plate Method. Anti-inflammatory activity was evaluated using Formalin induced paw edema model, Croton oil ear edema in rats. Trichilia connaroides bark ethanolic extracts produced significant analgesic activity in both Hot plate and acetic acid induced writhing models in mice. In hot plate method percentage increase in reaction time was determined where as in acetic acid induced writhing model percentage decrease in writhings was determined. Evaluation of anti inflammatory activity was done by Formalin induced paw edema model, Croton oil ear edema model. In Formalin induced paw edema model mean change in paw volume and percentage protection were calculated. In croton oil ear edema model the difference between untreated ear and treated ear were determined which indicated degree of inflammatory edema. The study revealed that the "Trichilia connaroides" bark possess a significant analgesic and anti-inflammatory activity.

Abstract

The present study was designed to evaluate the antidepressant and anti-inflammatory activity of "Curcuma aromatica" oil and "Curcuma aromatica" extract using different animal models. Antidepressant activity was evaluated by using various animal models. The degree of antidepressant activity was determined by measuring the immobility time in forced swim test and tail suspension tests. Anti-inflammatory activity was evaluated using Carrageenan induced paw edema model. Animals treated with all three doses of CAO (250,500 and 750mg/kg) witnessed a decrease in their immobility times in FST and TST which was significant when compared with control. Similarly, animals treated with Imipramine (15mg/kg), as expected showed a significant decrease in the immobility time.

Carrageenan induced paw edema model was employed to evaluate the anti-inflammatory activity of ethanolic extract of "Curcuma aromatica". Carrageenan induced paw edema model uses change in paw volume of control, test, and standard respectively to find out percentage inhibition of edema .The study revealed that the "Curcuma aromatica" rhizome oil possess a significant antidepressant and anti-inflammatory activity.

Abstract

The present study aimed at Formulation Development and Evaluation of controlled release tablets of Cinitapride for the treatment of ulcer. Cinitapride is a gastroprokinetic agent and antiulcer agent of the benzamide class. It act as an agonist of the 5- HT₁ and 5- HT₄ receptors and an antagonist of the 5- HT₂ receptors. It is used in the treatment of gastrointestinal disorders associated with motility disturbances such as gastro esophageal reflux disease, non- ulcer dyspepsia and delayed gastric emptying. The matrix tablets of Cinitapride were prepared using wet granulation. Physical characterization of tablet and powder blends used to form the matrix tablet was under taken using a range of experimental techniques. Granules were evaluated for Bulk density, Tapped density, Compressibility index and Hausner's ratio. Tablets were tested for weight variation, hardness, thickness and friability as per official procedure. The tablets were evaluated for in-vitro drug release profile. Dissolution studies of Cinitapride controlled release tablets in media with different dissolution media 0.1N HCl, Phosphate buffer pH (6.8) as per US Pharmacopoeia. The dissolution data revealed that the ratio of polymers is very important to achieve a optimum formulation. The formulation of Cinitapride CR tablets shown that formulation F23 with Methocel K100M (20%) shown good drug release profile. Formulation F23, shown similar dissolution profile when compared with the marketed product (Cintapro). Stability study of the formulation F23 indicated no significant difference in release profile after a period of 3 months.

Abstract

The objective of this research was to formulate fast dissolving tablets of tapentadol that disintegrate in the oral cavity upon contact with saliva and there by improve therapeutic efficacy. Tapentadol is used for the treatment of moderate to severe pain for both acute (following injury, surgery, etc.) and chronic musculoskeletal pain). Fast dissolving tablets of tapentadol were prepared by direct compression method comprising of three different superdisintegrants-Sodium starch glycollate, Crosscarmellose sodium and Crosspovidone (2%, 4%, 6% and 8%) and diluent viz: microcrystalline cellulose. Twelve formulations were prepared and evaluated for hardness, thickness, friability, weight variation, drug content, in vitro disintegration time, in vitro dispersion time, wetting time, water absorption ratio and in vitro dissolution studies. FTIR and DSC studies revealed that there was no chemical interaction between the drug and the excipients. Formulation M12 was found to be the best on the basis of wetting time, in vitro disintegration time and in vitro drug release. The formulation M12 containing microcrystalline cellulose as diluent and crosspovidone (8%) as disintegrant was found to be the optimized combination. Stability studies were carried out at 25°C±2°C/60%±5% RH and 40°C±2°C/75%±5% RH for formulation M12 for 60 days. The results of stability studies indicated no significant changes with respect to physicochemical properties, in vitro disintegration time, wetting time and in vitro drug release.
