PURPOSE: To compare the effects of the antidepressant drugs duloxetine and fluoxetine on depressive behaviors in rodents. METHODS: Eighteen male Wistar rats were given systemic injections of duloxetine, fluoxetine, or saline prior to a Forced Swimming Test (FST). Immobility and number of stops were measured. RESULTS: Rats given injections of fluoxetine displayed significantly less immobility (p = 0.02) and fewer stops than the control group (p = 0.003). Duloxetine significanlty reduced the number of stops (p = 0.003), but did not effect immobility (p = 0.48). CONCLUSION: Duloxetine and fluoxetine reduced depressive behaviors in the Forced FST. However, our findings suggest that fluoxetine is more effective than duloxetine.

PURPOSE: To compare the effects of the antidepressant drugs duloxetine and amitriptyline on depressive behaviors in rats. METHODS: Fifteen male Wistar rats were given systemic injections of duloxetine, amitriptyline or saline prior to a Forced Swimming Test (FST). Immobility and number of stops were measured. Data were analyzed by one-way ANOVA and Kruskall-Wallis. RESULTS: Rats given injections of duloxetine displayed fewer stops than the amitriptyline and control group (p< 0.05). The control group and Amitriptyline showed no difference (p=0.8). CONCLUSION: Duloxetine reduced depressive behaviors in the Forced Swimming Test been more effective than amitriptyline.

Aim: To evaluate the antiamnesic and antidepressant effect of Foeniculum vulgare whole crushed seeds. Study Design: Laboratory based randomized control study. Place and Duration of Study: Department of Pharmacology, University of Karachi between January 2018 to August 2018.  Methodology: Thirty swiss albino mice and wistar rats were divided equally in three groups. Control group was fed on standard rodent diet, group 2 was fed on 2% Foeniculum vulgare diet and group 3 was given 4% Foeniculum vulgare diet. Antidepressant activity was assessed using forced swimming test. Memory enhancement effect was evaluated by stationary rod test, passive avoidance test and water maze test. Results: Increased duration of struggling time was noted in both group 2 and group 3 as compared to control in forced swimming test. Decrease in time to reach platform in both water maze and stationary rod test was recorded in both the study group (group 2 & 3). Increase in step through latency was also seen in group 2 and group 3 as compared to control group. Conclusion: The results showed the memory enhancing and antidepressant actions of Foeniculum.

Background: Depression is a group of disorders results from a combination of multiple etiologic factors- genetic, biochemical, psychodynamic and socio-environmental. A depression consists of following clinical features as sadness, apathy, changes in sleep pattern, impaired concentration, feeling of shame or guilt and thoughts of dying or death. Fluoxetine and riluzole both are used for the treatment of depression in human being. Fluoxetine is SSRI (selective serotonin reuptake inhibitors) and riluzole is anxiolytic and mood stabilizer.Methods: Healthy male albino rats weighing between 150-200 grams were taken for the present study. Study animals were divided into three groups randomly with each group consisting of ten animals. Drugs were powdered with help of mortar and pestle and mixed in gum acacia solution. Appropriate volume of the freshly prepared solution was administered orally daily between 9 am to 10 am to all animal as per their individual body weight. Group A administered 1ml of 0.9% normal saline orally and serves as control group. Group B administered 0.4 mg of fluoxetine orally. Group C administered 2 mg of riluzole orally. Animals were evaluated for antidepressant activity using model- forced swimming test.Results: The results in the forced swimming test were assessed by duration of immobility in last 4 minutes of total 6 minute test duration. Antidepressant activity is indicated by the reduction in the duration of immobility i.e. lesser the duration more the efficacy. The results have been expressed as mean±standard deviation of duration of immobility in seconds during 6 minute period.Conclusions: There was significant difference in antidepressant activity of fluoxetine with antidepressant activity of riluzole. Riluzole showed antidepressant activity after two weeks of starting the drugs.
