Clinical evaluation of the tolerability and efficacy of trovafloxacin compared with sparfloxacin in the treatment of lower respiratory tract infections.

OBJECTIVE: To evaluate the clinical tolerability and efficacy of trovafloxacin compared with sparfloxacin in the treatment of lower respiratory tract infections. DESIGN: This was a randomised, double-blind, controlled, parallel study. PARTICIPANTS AND INTERVENTIONS: 92 patients with lower respiratory tract infection were enrolled in three centres. 45 patients received trovafloxacin 200mg once daily orally for 10 days and 43 patients received sparfloxacin 400mg on the first day and 200mg once daily orally for 9 days. Clinical evaluation was performed for fever, dyspnoea, pulmonary symptoms, cough and sputum on days 1, 3, 6 and 12 of the study along with bacteriological evaluation on days 1 and 12. Any adverse effects were also recorded during the study period. RESULTS: There was a significant reduction in the severity of symptoms from day 4 until the end of the study. Clinical cure or improvement was seen in 87 and 95% of the trovafloxacin and sparfloxacin groups, respectively. Bacteriological eradication rates were 84 and 89% for the trovafloxacin and sparfloxacin groups, respectively. The number of adverse effects was 10 and 13 reported by 10 and 13 patients in the trovafloxacin and sparfloxacin groups, respectively. CONCLUSIONS: Trovafloxacin is well tolerated and effective in the treatment of lower respiratory tract infections in a dosage of 200mg daily. It was observed that the efficacy and tolerability of trovafloxacin is comparable to that of sparfloxacin (200mg daily, with a loading dose of 400mg on the first day) in the treatment of lower respiratory tract infections. However, further studies are needed to confirm this.

Role of prostaglandin synthesis inhibitors on chemically induced seizures.

The study was conducted to find out the possible role of prostaglandin synthesis inhibitors on different parameters of chemically induced seizures in albino mice. The results suggest that prostaglandins have a proconvulsant activity. Augmentation of central dopamine and serotonin levels is partly responsible for the inhibitory effect of prostaglandin synthesis inhibitors on chemically induced seizures.

Evaluation of efficacy and safety of losartan potassium in the treatment of mild to moderate hypertension as compared to enalapril maleate.

AIM: To study the effect of losartan potassium in the treatment of mild to moderate hypertension and to compare its efficacy and adverse effect profile with enalaparil maleate. MATERIAL AND METHODS: One hundred and forty five patients with mild to moderate essential hypertension were enrolled in this randomized, double blind, controlled, parallel and multicentric study. Seventy two patients received losartan potassium 50 mg and seventy three received enalapril maleate 5 mg. RESULTS: Losartan potassium reduced the DBP to < 90 mm Hg in 59% of the patients at the end of 8 weeks compared to 45% in the enalapril maleate group. DBP was reduced by 10 or > than 10 mm Hg in 89% of the patients with losartan as compared to the baseline whereas it was 80% in the enalapril group. Percentage of side effects seen in losartan and enalapril groups were 12 and 22 respectively. CONCLUSION: Losartan potassium is an efficacious antihypertensive agent in mild to moderate hypertension. It also has fewer side effects when compared to enalapril maleate.
