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.
Background: The aim of this study was to analyze the cost ratio and percentage cost variations in different brands of the commonly prescribed anti-epileptic drugs available in Indian pharmaceutical market.Methods: The maximum and minimum price of each brand of the drug given in Indian rupees (INR) was noted by using CIMS January to April 2020 edition and drug today April to June 2020 volume 1. The cost ratio and the percentage cost variation for individual drug brands was calculated. The cost of one bottle in case of 100 ml syrup and 10 tablets/capsules was calculated in case of oral drugs and the cost of one 1 vial or ampoule was noted in case of injectable drugs. At last the cost ratio and percentage cost variation of various brands was compared.Results: After calculation of cost ratio and percentage cost variation for each brand of anti-epileptic drug tablet clonazepam (2 mg) shows highest cost ratio and percentage cost variation as 10.41 and 941.66, carbamazepine (200 mg SR tablet) shows lowest cost ratio and percentage cost variation as 1.09 and 9.32.Conclusions: Epilepsy is the most common neurological disorder and epileptic drugs are to be prescribed for prolonged period. If a costly brand is prescribed, the patients have to pay more money unnecessarily for their treatment. There is a wide difference in the cost of different brands of anti-epileptic drugs available in India. The clinicians prescribing these drugs should be aware of these variations in cost to reduce the cost of drug therapy.
Background: Depression is a common psychiatric illness but conventional antidepressants are often shows unpredictable response. Pharmacological profiles of many atypical antipsychotics have potential antidepressant effect. Ziprasidone is an atypical antidepressant with 5HT1A agonistic activity and 5HT1D, 5HT2A and D2 receptors antagonistic activity. It’s a potential candidate for evaluating possible antidepressant activity.Methods: Behavioural despair test are widely used for evaluation of potential antidepressant molecule. Tail suspension test is a variant of behavioural despair test. Healthy male Wistar albino rat 18 in number and weighing between of 150-200 grams were divided in 3 groups with 6 rats in each group. Group A was treated with 0.9% Normal Saline, Group B with Fluoxetine and Group C with Ziprasidone for 28 days. Tail suspension test was done on day 0, 7, 14, 21 and 28 days.Results: In comparison to Normal saline both the drugs shows significant antidepressant activity after 28 days of treatment. While antidepressant activity of fluoxetine started to appear from day 7; that of ziprasidone started to appear from 14th day.Conclusions: Ziprasidone can be suitable candidate for clinical trials of Major Depressive Disorders not responding to conventional antidepressant.

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 1.6 mg of ziprasidone orally. Animals were evaluated for antidepressant activity using two models – Tail suspension test and Forced swimming test.Results: The results in the tail suspension test were assessed by duration of immobility in 6 minutes duration. Antidepressant activity is indicated by the reduction in the duration of immobility i.e. lesser the duration indicates more effectiveness of the drug.Conclusions: There is significant difference in antidepressant activity of fluoxetine with antidepressant activity of ziprasidone.
