Ingredients	Uses
Clotrimazole	Clotrimazole is the main ingredient of this formulation and you can say it as active ingredient. Effect of this ingredient is manifested by the product. You find it as an effective drug, for combating against fungal infections. Mainly candida or aspergillus fungal infection is treated by it.
Sterile water for injection	Sterile water for injected is regarded as vehicle and necessary for the production of Clotrimazole ear drops. It facilitates the drug formation in liquid form so that drug can reach its required area.
Propylene glycol	Propylene glycol is served as solvent. It can enhance the solubility of the active ingredient. You can also find it helpful in delivering the drug to local area.
Glycerin	Glycerin is added to provide moisturizing effect in the formulation. You find it as a good humectant and you can feel soothing effects due to this ingredient.
Polyethylene glycol	Polyethylene glycol is supposed to be added as co-solvent. It can improve viscosity of formulation. You can also add this ingredient to increase lubricating effects of product.
Benzyl alcohol	Benzyl alcohol is a well-known preservative and it discourages the microbial growth. Here it is added for the same purpose.
Citric acid	You can incorporate citric acid as buffering agent. The function of buffering agent is to keep the pH of formulation in optimal range. You are administering the drug into ear, so it must possess pH that is suitable for your body.

8.Can you elaborate the manufacturing process of Clotrimazole ear drops?

Steps of manufacturing process	Information
Procuring raw material	Clotrimazole is a synthetic antifungal agent. You have to procure it from some documented source. It is active ingredient of this formulation, that’s why quality assessment is integral before adding the active agent into the formulation. Other ingredients are excipients and their quality equally matters. They are procured from authentic supplier. Sterile water for injection is obtained by treating water by the help of water purification system.
Weighing raw material	Ingredients must always be added in desired amounts; otherwise you may experience low effects of formulation. Here you need standard weighing balance to measure the precise amount of ingredient required for manufacturing. You are advised to weigh the ingredients in close system like laminar air flow cabinets, where chances of contamination are get nullified.
Dissolving ingredients	Do you know Clotrimazole is not water-friendly chemical? It required lipophilic solvent to get dissolved completely. Initially Clotrimazole is dissolved in propylene glycol by keeping conditions favorable, such as constant stirring. Mixing vessel is used for this purpose. On the other hand, aqueous solution is also got prepared. This solution contains sterile water for injection, glycerin and buffer. Mixing vessel remains helpful for making the solution. Now you keep the temperature of aqueous solution warm to ease the dissolution. Add Clotrimazole solution into the aqueous solution gradually.
Mixing ingredients	Now all ingredient are needed to be mixed homogenously, for this purpose high shear mixer is applicable. Remaining ingredients benzyl alcohol and propylene glycol are also incorporated in the formulation. All mixing process is carried out by the help of high shear mixer.
Filtering the formulation	This homogenous mixer is filtered by using sterile filter. All the possible impurities and microorganisms are eliminated from the formulation.
Filling and sealing of formulation	Formulation is prepared to fill it in dropper bottles. The filling process starts with loading of dropper bottles into the filling machine by conveyor. Dropper bottles are shifted to filling unit, where bottles are filled with required volume of formulation. After filling, dropper bottles are moved to stoppering unit. Nozzle is placed on the opening of bottle for ease in administrating dose. After that dropper bottles are preceded to sealing unit, where screw caps are used to seal the dropper bottles.
Sterilizing the final product	After filling and sealing process, final product is being sterilized by the help of autoclave. This ensures the removal of microorganism and reduces the contamination possibility.
Testing the quality	Testing the quality of product is requisite. You can estimate the quality by performing different tests. Stability, pH, microbial presence, sterility, purity etc. of formulation can be evaluated to attain the information about quality.
Labeling & cartoning	The final product is labeled with printed label. This label tells you about name of product, volume, expiry, storage instructions etc. After labeling, dropper bottle is packaged in a box by utilizing cartoning machine.

9.What kind of equipment is needed for manufacturing of Clotrimazole ear drops?

Manufacturing of Clotrimazole ear drops demand for some particular equipment that can also function according to regulatory standards. Here you can acquire the knowledge about important equipment, which is needed in every step of manufacturing.

Equipment	Function
Water purification system AIPAK Water Purification System	Water purification system enables you to obtain sterile water for injection. It guarantees the purity and quality of water, which is then used in manufacturing process. Different mechanisms works behind this water purification system like reverse osmosis, distillation or ultrafiltration.
Mixing vessel	Mixing vessel is applicable for dissolving Clotrimazole in propylene glycol and mixing it with water, glycerin and buffer. This equipment contains agitator that has role in mixing ingredients together. This agitator moves with high speed to perform mixing process. Temperature can also be controlled in this vessel. For dissolution of Clotrimazole solution into aqueous solution, you need to warm the temperature of aqueous solution.
High shear mixer AIPAK high shear mixer	High shear mixer ensures you the formation of homogenized mixture. This equipment applies high shear forces by rotating in rapid speed. These forces cause the uniform blending of ingredients.
Sterile filter	Sterile filter possesses 0.2 µm membrane that facilitates the filtration process. All contaminants either particles or microbes, retain in the membrane and you obtain the sterile filtrate. This filtrate is then filled in packaging container.
Dropper bottle filling machine	Dropper bottle filling machine is used to fill Clotrimazole ear drops into the dropper bottles. You find it very convenient and efficient for carrying out this step. This machine works automatically and fills and seals the dropper bottles accurately. It consists of some important parts, which include: Filling unit. Stoppering unit. Sealing unit.
Autoclave	Autoclave serves as a useful equipment to sterilize containers and final products. It is counted as compulsory part of pharmaceutical manufacturing. Clotrimazole ear drops contain heat sensitive ingredients; autoclave uses steam to sterilize this formulation.
Labeling machine	Labeling machine is helpful in applying labels on dropper bottle. Labels are first printed then placed on container by using pressure applying adhesives or hot melt glue.
Cartoning machine	Cartoning machine is applicable for packaging dropper bottle in to the boxes. Boxes contain important information about product. It works by forming boxes, then fill the boxes with dropper bottles. After placing dropper bottle in box, it is closed by tuck in method.
