Introduction
Cefoperazone sodium is a third-generation semisynthetic antibiotic that is used in the treatment of infections caused by susceptible microorganisms [1]. It is official in United States Pharmacopoeia, Chemically, cefoperazone sodium is 7-[R{2-(4-ethyl-2,3- dioxopiperazin- 1-yl carboxamide)-2-(4-hydroxylphenyl) acetamide}-3-[1- methyl-1H-tetrazol-5-yl-thiomethyl]]- 3-cephem-4-carboxilate. Its molecular formula is C25H26N9NaO8S2. Cefoperazone is wide spectrum and third generation of cephalosporin occupied in management of respiratory tract in addition to urinary infections [2]. Now drug interaction be capable of simply be distincted as interaction connecting a drug in addition to other substance with the intention of prevents drug commencing the stage as predictable. These connections may happen due to be short of knowledge regarding the main ingredients implicated in the related substances [3].Two medicines are antagonistic at what time their interaction occurs a reduce in special effects of one or else both of medicines. The dissimilar responses of receptor to act of a medicine has affected in number of arrangements, which use expressions such as “partial agonist”, “competitive agonist” etc. This is even expected that a lot of authors would mismanage any given arrangement [4] Commonly iron complexes were used in convey of oxygen in human blood as well as tissues. A mature at rest takes 250ml of uncontaminated oxygen for each minute, these oxygens conceded by metal complex convey system recognized heame, alloying oxygen to go away the blood at what time it arrives the tissue [5].
Antibiotic and metal interaction and successfully found there after interaction result. Also, the antimicrobial activity of drug and the metals complexes were determined. This has been seen that the antibiotic interacts along with metal at the pH 7.4. The different essential metal intricate of the many drugs has been synthesized in addition to characterized by the techniques like NMR, UV, atomic absorption, FT-IR as well as elemental analysis. Spectroscopic, IR Spectroscopic, disk diffusion method, Biological assay studies of complexes [6]. On the other hand, in this interaction there uses metals complex which are interaction with drug into our body. And have been use their various type of bacteria for finding zone of inhibition. Some paper there uses methanol and ethanol for disk diffusion result clearly showing. Cefoperazone in a single way then it has a high bioavailability and proportionally increasing the absorption with concentration. But if we use its interaction with metals then its bioavailability and absorption decrease and less half-life [7]. By using there, a various of methods and study such as Antifungal study, Antibacterial study, Biological study with different type of spectroscopic analysis, Conductometric, IR spectrometric and Disk-diffusion methods its shows that’s less pharmacological action [8]. So that after all discussion it can state that if it is taken antibiotic then it will be used the metals complex before two hours and after one hour.
Materials and Methods
Cefoperazone stock solution 250milliliter of 1x10-2 Molar was ready by softening 1.386gm of Cefoperazone solution in the 250 milliliter of the demineralized water (DMW) in a 250milliliter volumetric flask. The reserve solution was thinned to desired potency by the buffer solution [9] (Tables 1 & 2).
Table 1: List of chemicals and reagents.
Table 2: List of instruments &equipment’s.
Preparation of Metal Solutions
For the grounding of 0.01 Molar metal solution like zinc sulfate heptahydrate (exactly 0.28754gm) was evaluated exactly in addition to initiated with the assist of the funnel in a 100ml volumetric flask, softened in DM water in addition to framework to the mark by the similar solvent. These prime solutions were additional diluted ten creases in the equivalent solvent along with the concluding solutions were 0.0001 M concentration.
Preparation of Antacid Solutions
For the preparation of 0.01M antacid solution, Mg(OH)2 (0.0740gm) was evaluated accurately in addition to initiated with the facilitate of funnel in 100milliliter volumetric flask, softened in the demineralized water furthermore construct up to mark by the equal solvent. These primary solutions were further diluted ten folds in the same solvent and the final solutions were 0.0001 M concentration [10].
Grounding of the Buffer Solutions
To get ready buffer solution 1.76gram of the disodium hydrogen phosphate were softened in the demineralized water by 2.43 gram of the solution dihydrogen phosphate in addition to pH was altered to 7.4 as well as volume was completed to 1000 milliliter with the equivalent solution [11].
Grounding of the Typical Curve of the Cefoperazone
Cefoperazone reserve solution at the pH 7.4 in addition to concentration of the 1x10-5 Molar was inserted in unlike concentrations to the 10 test tubes, to have subsequent concentrations like 9x10-5 Molar, 8x 10-5 Molar, 7x10-5 Molar, 6x10- 5 Molar, 5x10-5 Molar, 4x10-5 Molar, 3x10-5 Molar, 2x10-5 Molar, 1x10-5 Molar. Now the solutions were suitably mixed. Then the absorbance values of solutions were established at 585nm through UV spectrometer [12].
Using Disc Diffusion Process
Solution of celebrated concentration (3μg/ml) of trial samples are completed through dissolving measured quantity of the trials in calculated amount of solvents. Dried in addition to sterilized filter term paper discs (6mm as a diameter) are subsequently impregnated with recognized amounts of trial substances by using micropipette. Discs holding the test substances are positioned on the nutrient agar media homogeneously seeded by the test organism, typical antibiotic discs along with blank discs were utilized as positive furthermore negative control. These plates now are kept at the low temperature like 4oC for the 24 hours to permit maximum diffusion. Throughout this time desiccated discs suck up water from surrounding medium furthermore the trial materials dissolve along with spread out of the trial disc. The diffusion happens according to physical law to controls diffusion of the molecules during agar gel. Consequently, there was a gradual alter of trial substances concentrations in medium adjoining the disc [13].
Results and Discussions
From the subsequent Table 3, this can monitor to the absorbance of the Cefoperazone enhances with the enhancing concentration in keeping with Beer Lambert’s equation (Table 4). From the Table 5, it can observe that the absorbance of Cefoperazone is different when it interacts with Mg (OH)2. From the Table 6, it can observe that interaction between drug and metal may lead to form complexes which have different light absorption capacity and spectrum pattern is altered. So, any alteration and spectrum behavior are regarded as a tool for primary interaction from the spectral studies.

Outcome of the Metals on Cefoperazone by Job’s Technique of Incessant Variation:
The molar proportions of complexes of the Cefoperazone by metal salt were calculated approximately through Job’s method. The examined absorbance rates were calculated in the pH 7.4 at diverse concentration like 1x10-5 to 9x10-5 Molar of Cefoperazone by metal salt. Then Job’s plots at the pH were acquired through plotting absorbance variation against mole portion of drug (Table 7). From the above we can observe that Cefoperazone forms strong 1:1 complex with zinc sulfate heptahydrate which is indicated as inverted ‘V’ shaped curve. From the above we can observe that Cefoperazone forms strong 1:1 complex with Mg (OH)2 which is indicated as inverted ‘v’ shaped curve (Table 8).

Antimicrobial Reading
The antimicrobial effectiveness of the trial agents is calculated by their action to avoid the enlargement of microorganisms neighboring discs which provides clear precinct of inhibition. Later than incubation, the antimicrobial actions of the trial materials were concluded through measuring diameter of zones of the inhibition inside millimeter through a crystal-clear mm scale (Table 9). The trial samples were examined in opposition to Staphylococcus aureus. The typical Cefoperazone disk also checked in opposition to Staphylococcus aureus. The consequences of the antimicrobial action calculated in view of diameter of the zone of the inhibition in the mm were demonstrated in Table 10. Antimicrobial sensitivity testing of Cefoperazone against Staphylococcus aureus after interacting with ZnSO4.7H2O and Mg (OH)2 solution, respectively. Now it was proved that zone of the inhibition of the Cefoperazone through Metal and antacid Zn, Mg reduced from 16mm to 14mm & 13mm correspondingly due to the metal, antacid and drug interaction.

Conclusion
Though, there were some limitations in this research work like proper financial support from any side, active pure drug collection was not easy in Bangladesh. Eventually it has been overcome. The sophisticated spectrophotometric technique is easy, straight as well as worthwhile for the fortitude of drug. Commencing this spectral reading, this has been observed that Cefoperazone provides a spiky peak at the 585nm. At what time Zinc Sulfate furthermore antacid solution, Mg (OH)2 combined with Cefoperazone 1:1 ratio and the strength of peak alters extremely and absorption features are changed due to the interaction although the position of complex do not change. Then antimicrobial viewing of a mediator is crucial to find out its spectrum in opposition to various natures of the pathogenic microorganisms. The Job’s plot has provided the molar percentage of the complexes of Cefoperazone through Zinc Sulfate in addition to antacid solution like Mg (OH)2. At the pH 7.4 Cefoperazone structures tough 1:1 complex through Zinc Sulfate in addition to antacid solution like Mg (OH)2 designated as ‘^’ natured curves. These curves can indicate well-built kinetics of the complexation between Cefoperazone by Zinc Sulfate along with antacid solution like magnesium hydroxide. The trial samples were checked in opposition to Staphylococcus aureus. The typical Cefoperazone disk also checked in opposition to Staphylococcus aureus. It was examined that antimicrobial action of the Cefoperazone reduces when it structures complexes through ZnSO4.7H2O in addition to antacid solution like magnesium hydroxide. Thus, through antimicrobial examination it was proved that zone of the inhibition of the Cefoperazone through Metal and antacid Zn, Mg reduced from 16mm to 14mm & 13mm correspondingly.
