Two Rapid, direct, ecological friendly and economical spectrophotometric methods were used for estimation of meloxicam in the market Tablet dosage form. The First method is based on the use the fourth order derivative spectrum (D4) and the second method is depend-ed on the ratio of the area under the curve for the two peaks in the drug (Compensated area under the curve). The linear calibration graphs of the two methods were measured in the con-centration range (5-35)mg/l and the average of recoveries for local market Tablet (AWA)® were 99.8% for D4 method and 100.2% for CAUC method which indicating a good accuracy and precision for these methods. In this study, the results obtained by these suggested meth-ods have been successfully statistically compared by t-test and Mann-Whitney test showed a good agreement.

Introduction:Klebsiella pneumoniae are Gram-negative which cause many diseases such as urinary tract infections, respiratory tract infections and septicemia. Inulinase is an enzyme used in food manufacture and pharmaceuticals. Inulinase is used in decreasing lipid ratio and, cholesterol in blood and considered as a prebiotic factor inside intestine. Many microorganisms can produce inulinase, such as yeast, fungi and bacteria; among such bacteria: Bacillus spp., Arthrobacter spp., and Pseudomonas spp. but there are no studies about inulinase production by K. pneumoniae have been reported. So the current study aims at investing the ability of producing and purification inulinase by K. pneumoniae. Method: K. pneumoniae were isolated from many hospitals and screened for the production of inulinase. Isolation percentage was 32%. A combination between the enzyme and the ceftazidime were assayed for detecting the antibacterial activity agonist Gram positive and Gram negative bacteria were done. Results: It is found that K. pneumoniae K4 isolate is the best producer of this enzyme. Inulinase, purified with ammonium sulfate at 70% saturation with specific activity 7.01 U/mg protein. As well, it's found that inulinase had increased the activity of ceftazidime against bacteria when combination between this enzyme and the antibiotic had done. Conclusion: This study proves for the first time that K. pneumoniae can produce inulinase which can be used in tremendous applications and also proves the broad spectrum bioactivity of inulinase against microbial pathogens. Ceftazidime antimicrobial activity against bacteria, is increased when a combination between inulinase and ceftazidime had done.

Accurate, direct and inexpensive spectrophotometric methods have been used for simultaneous estimation of Baclofen in bulk and tablet dosage form. The proposed methods were applied in the wide concentration ranges of (50-450 mg/L). The detection limits were (0.451) for AUC1 and (0.520) for AUC2. The limit of quantitation was found to be (1.366) for AUC1 and (1.576) for AUC2. The results were analyzed statistically by using recovery and relative standard deviation studies.
