Lubricants are used to minimize the faction between the moving surfaces of the machines. Fraction may cause the heating of the moving parts. It also helps to minimize the load on the machine and rust. Generally lubricants are prepared with organic and synthetic compound those are not permitted in pharmaceuticals.

In the pharmaceutical industry and bioscience research field, many laboratories make use of analytical balances. The analytical balances used in the bioscience research and pharmaceutical industry are very sensitive. These balances can be heavily affected by the way the measuring personnel handle them and by the environment in which they are installed. The environment in the pharmaceutical laboratory needs to be assessed by running assessment tests. Based on the results of these assessments should be proposed concrete measures for improving the lab environment.

There are different forms those are issued by the FDA at the different stages of the regulatory audits. Different issues are communicated through these forms between FDA and the manufacturing facility. Some of them are:
1. Form 482 - Notice of Inspection
2. Form 483 - Observations of Inspection
3. Form 484 - Receipt of Samples
4. Form 463 - Affidavit

A lot of pharmaceutical professionals have confusion between Form 483 and Warning Letters. Both of these are issued by Food and Drug Administration (FDA) after a regulatory inspection of manufacturing facility and both are the way of communication.

Validation of effective working of UV light in purified water system aims to demonstrate that the UV light purification process when operated within set limits produces highly purified pharmaceutical water with a high degree of assertion. Validation of this method is necessary to get pharmaceutical water with all necessary quality attributes. Validation also offers a framework to initiate full control over the procedure, which monitors efficiency, safety and ultimately the method outcomes.

Water is widely used and an important raw material in the processing, formulation and production of pharmaceutical products and medical devices. Purified water has unique chemical properties making it ideal to absorb, dissolve or adsorb many different compounds. Having a purified water system in pharmaceuticals is a great way to control the quality of water all through the production, storage and distribution processes.

Water is a key element for the pharmaceutical and healthcare industries. Pharmaceutical manufacturers are concerned with producing purified water that meets defined standard quality to minimize any risk to patients' health or interfere with the manufacturing process. Water acts as an important ingredient in many formulations and also as a cleaning agent. This makes the production of highly purified water and pyrogen free for injection to very critical and should meet the international standards. The most commonly and accepted method of purification is the use of mixed bed ion exchanger in the purified water systems for pharmaceuticals.

The main ingredient in most of the pharmaceutical products used by people is water. Given the ever increasing concerns about the ingredients used to make pharmaceutical products, it is important to ensure that the water used is stable and consistent. The Reverse Osmosis (RO) system is at the heart of the process of water purification. It uses semi-permeable polyamide membranes that provide rejections of organic and ionic impurities that exceed 99%. The RO membranes pores are in real sense intersegmental spaces within the polymer molecules. The membranes are large enough to allow permeation of water molecules but not big enough to allow hydrated chemical ions to pass through. Below is a look at how sanitization of membranes in purified water system is done.

Balances are used to weigh different things as raw material, dispensed material and samples. Sometimes very low quantity is weighed for analysis. An error in the weighed material can cause a big variation in analytical results.

The primary goal of any synthetic process is to create completely pure products, though in reality marginal amount of impurity always has been found to be present in the final product after the complete chemical synthesis and manufacturing process. The presence of the impurities can enhance the level of toxicity and that is why an impurity analysis process has been carried out. Understanding the nature of these impurities is important. The goal of the analysis is to check whether these impurities may bring possible hazards or not. There are some known and unknown impurities in pharmaceutical analysis. The intention of pharmaceutical analysis should be to omit these impurities completely; if not then their intensity should be taken down to a controllable level so that no possible hazards can take place.

Stability of the pharmaceutical products is determined by storing the product under Accelerated and Long Term Conditions. The product is then analyzed at different time stations for any significant change in physical or chemical condition.

All pharmaceutical drugs degrade with the time forming the byproducts. These byproducts may harmful for health of the patients consuming the drug. Shelf life of the pharmaceutical products is the time period for which the product maintains its identity and quality when stored at the conditions defined on the label of the product.

Sample is a portion of a material collected according to a defined sampling procedure. The size of any sample should be sufficient to allow all anticipated test procedures to be carried out, including all repetitions and retention samples.

Forced degradation is also known as stress testing and drug is degraded forcefully by applying artificial methods. It is a useful tool to predict the stability of any Active Pharmaceutical Ingredient (API) or formulation product. It helps to know about the impurities developed during the storage of drug products in various environmental conditions.

Different types of inspections are conducted by Regulatory Agencies. Following are the various types of inspections conducted periodically by Regulatory Agencies.
- Routine Inspection: Quality System Inspection
- Pre-approval Inspection for Pre-market Approval (PMA): Country specific inspections
- Follow-up on a warning letter (Violation): Inspector will look for evidence of the company's compliance with a plan of action made in the response to the warning letter.
- For-cause Inspection (Investigational): Inspectors have specific directions for the inspection that are not publicly available.

In order to achieve its effect, a drug must first be administered in a suitable dosage form at an appropriate site. It must be absorbed effectively from the site of administration and distributed in the body to reach its site of action. After its action, for the termination of its effect, the drug must be metabolized, and metabolites must be excreted from the body.

Fluidized bed dryer (FBD) is well known and widely used equipment in pharmaceutical manufacturing. It is used in granulation process for drying the material to get desired moisture content in the tablet formulation granules.

Revalidation of any process is an essential part of the validation. It improves the quality of the product and increases the smoothness of the process.

Proper execution of protocol is an important part of the validation process. Execution of validation protocol affects the validation results. There should be minimum deviations during the validation process.
Jul 13, 2014
A protocol is a written statement to conduct the validation process along with the procedure, test method, equipment handling, specifications, acceptance criteria, report and approval.
