Important parameters of syrup preparation

Excessive heating in the preparation of syrups must be avoided to prevent inversion of sucrose, with increased tendency to fermentation.

 The syrup is prepared by adding sucrose to the aqueous solution in a bottle of about twice the size required for the syrup. This permits active agitation and rapid solution.

 The stoppering of the bottle is important, as it prevents contamination and loss during the process.

 Preservatives such as glycerin, methyl paraben, benzoic acid and sodium benzoate may be added to prevent bacterial and mold growth, particularly when the concentration of sucrose in the syrup is low.

 The official syrups should be preserved in well dried bottles and stored in a cool  dark



A pharmaceutical suspension may be defined as a coarse dispersion containing finely divided insoluble materials suspended in a liquid medium or available in dry form to be distributed in the liquid when desired.

 Aseptic area 

An aseptic area is a room or special area within a clean area designed, contracted, serviced and used with the intention of preventing microbial contamination of the product. In order to maintain the sterility of the components and the product during processing, careful attention needs to be given to:

  • Environment
  • Personnel
  • Critical surfaces
  • Container /Closure sterilization and transfer procedures
  • Maximum holding period of the product before filling into the final container.

Clean room

A controlled environment facility in which all incoming air passes through a filter capable of removing 99.997% of all particles 0.3 mili micron and larger ,called clean room.

Classification of aseptic room

  • A –class zone: Filling area under laminar air flow .Particle count of this area must be below 100 particles.
  • B-class zone: Other portion of filling room except A –class. Particle count of this zone is usually below 100 particles.
  • Buffer zone or C-class zone: It consists of cooling room, sealing room and third change room and is below 10000 particles.

Aseptic clean room preparation

Sterile production room must be maintained as CLASS-100. According to USP, CLASS-100 clean room is defined as the room condition, in which the particle count in the air is NMT 100 per cubic foot for particle of 0.5m or larger than that.

At first De-ionized water is sprayed throughout the room so that the particle present in the air must settle down. Then the wall, ceiling and floor are washed by the solution of combination of ethanol, savlon and distilled water.

After cleaning operation, the production room must be fumigated about 12 hours, with the solution combination of formaldehyde and potassium per manganate in the ratio of 3:1. 500ml formaldehyde and 175mg potassium per manganate for per 41 cubic meter area of an aseptic room.

UV light is also used for the removal of viable microorganism.

Preparation of Lyophilized Product


Lyophilization is a process which extracts the water from foods and other products so that the products remain stable and are easier to store at room temperature (ambiant air temperature).

Lyophilization is carried out using a simple principle of physics called sublimation. Sublimation is the transition of a substance from the solid to the vapour state, without first passing through an intermediate liquid phase. To extract water from products, the process of lyophilization consists of:

  1. Freezing the food so that the water in the food become ice;
  2. Under a vacuum, sublimating the ice directly into water vapour;
  3. Drawing off the water vapour;
  4. Once the ice is sublimated, the products are freeze-dried and can be removed from the machine.

Lyophilization process is also known as freeze-drying process.

The freeze-drying process

Typically, the lyophilized product is frozen at a temperature well below the eutectic point. There are four stages in the complete drying process: pretreatment, freezing, primary drying, and secondary drying.


Pretreatment includes any method of treating the product prior to freezing. This may include concentrating the product, formulation revision (i.e., addition of components to increase stability and/or improve processing), decreasing a high vapor pressure solvent or increasing the surface area Methods of pretreatment include: Freeze concentration, Solution phase concentration, Formulation to Stabilize Reactive Products etc.


Freezing is usually done using a freeze-drying machine. In this step, it is important to cool the material below its triple point, the lowest temperature at which the solid and liquid phases of the material can coexist. This ensures that sublimation rather than melting will occur in the following steps. Freezing is done rapidly, in order to lower the material to below its eutectic point quickly, thus avoiding the formation of ice crystals. Usually, the freezing temperatures are between −50 °C and −80 °C. The freezing phase is the most critical in the whole freeze-drying process, because the product can be spoiled if badly done.

Primary drying

During the primary drying phase, the pressure is lowered (to the range of a few millibars), and enough heat is supplied to the material for the water to sublime. In this initial drying phase, about 95% of the water in the material is sublimated. This phase may be slow (can be several days in the industry), because, if too much heat is added, the material’s structure could be altered.

In this phase, pressure is controlled through the application of partial vacuum. Furthermore, a cold condenser chamber and/or condenser plates provide a surface(s) for the water vapor to re-solidify on. Condenser temperatures are typically below −50 °C (−60 °F).

Secondary drying

The secondary drying phase aims to remove unfrozen water molecules, since the ice was removed in the primary drying phase. In this phase, the temperature is raised higher than in the primary drying phase, and can even be above 0 °C, to break any physico-chemical interactions that have formed between the water molecules and the frozen material. After the freeze-drying process is complete, the vacuum is usually broken with an inert gas, such as nitrogen, before the material is sealed.

At the end of the operation, the final residual water content in the product is extremely low, around 1% to 4%.


Lyophilized products are filled by three stages. One stage has included filling of vials and stoppering on line; another stage included filling of vials, transportation to the lyophilizer and then stoppering; a third stage included the filling of vials, loading in the lyophilizer, and exposure to a portion of the nitrogen flush and then stoppering. Since lyophilizer sterilization and sterilization of the nitrogen system used to backfill require separate validation, media fills should primarily validate the filling, transportation and loading aseptic operations.

Testing of Lyophilized Products

There are several aspects of finished product testing which are of concern to the lyophilized dosage form. These include

  • Uniformity of dose
  • Moisture and stability testing
  • Sterility testing of the product.

The advantages of Lyophilization

  • Ease of processing a liquid, which simplifies aseptic handling
  • Enhanced stability of a dry powder
  • Removal of water without excessive heating of the product
  • Enhanced product stability in a dry state
  • Rapid and easy dissolution of reconstituted product

Disadvantages of Lyophilization

  • Increased handling and processing time
  • Need for sterile diluent upon reconstitution
  • Cost and complexity of equipment

Metered dose Inhaler

A metered dose inhaler (MDI), also known as an aerosol inhaler or puffer, is a device for delivering medicine directly into the lungs. It consists of a pressurised metal canister containing a solution or suspension of medicine, placed within a plastic case with a mouthpiece. When the canister is pushed down, a valve delivers a measured dose of medicine in a fine mist. This is inhaled into the lungs via the mouthpiece. Using an inhaler delivers your medicine directly into the lungs where it is needed.

It is the most commonly used delivery system for treating asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. The medication in a metered dose inhaler is most commonly a bronchodilator, corticosteroid or a combination of both for the treatment of asthma and COPD. Other medications less commonly used but also administered by MDI are mast cell stabilizers, such as (cromoglicate or nedocromil).

Component of MDI


One of the most crucial components of a MDI is its propellant. The propellant provides the force to generate the aerosol cloud and is also the medium in which the active component must be suspended or dissolved. Propellants in MDIs typically make up more than 99 % of the delivered dose. As for example hydrocloroflurocarbon.


Packaging is the process by which the pharmaceutical products are suitable packed in such way that they should retain their therapeutic effectiveness from the time of their packaging to consume by the consumers.

There are two types of packaging

  1. Primary packaging. (Direct contact with the product e.g. PVC)
  2. Secondary packaging. (No contact with the product e.g. Carton)

Function of Packaging

HVAC System

HVAC (pronounced as four separate letters) is an acronym that stands for “heating, ventilating and air-conditioning” and generally includes a variety of active mechanical/electrical systems employed to provide thermal control in buildings. Control of the thermal environment is a key objective for virtually all occupied buildings.

A heating system (“H” in HVAC) is designed to add thermal energy to a space or building in order to maintain some selected air temperature that would otherwise not be achieved due to heat flows (heat loss) to the exterior environment. A ventilating system (“V”) is intended to introduce air to or remove air from a space to move air without changing its temperature. Ventilating systems may be used to improve indoor air quality or to improve thermal comfort. A cooling system (“C” is not explicitly included in the HVAC acronym) is designed to remove thermal energy from a space or building to maintain some selected air temperature that would otherwise not be achieved due to heat flows (heat gain) from interior heat sources and the exterior environment. Cooling systems are normally considered as part of the “AC” in HVAC; AC stands for air-conditioning.

 Objectives of HVAC system

  • Control air temperature
  • Control air humidity
  • Control air circulation and
  • Control air quality.


There are many different types of standard heating systems. Such a system contains a boiler, furnace, or heat pump to heat water, steam, or air, all in a central location such as a furnace room in a home or a mechanical room in a large building. The system also contains either ductwork, for forced air systems, or piping to distribute a heated fluid and radiators to transfer this heat to the air.


Ventilating is the process of “changing” or replacing air in any space to control temperature or remove moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and to replenish oxygen. Ventilation includes both the exchange of air to the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Ventilation is used to remove unpleasant smells and excessive moisture, introduce outside air, to keep interior building air circulating, and to prevent stagnation of

Air conditioning

Air conditioning and refrigeration are provided through the removal of heat. Heat can be removed through radiation, convection, and by heat pump systems through a process called the refrigeration cycle. Refrigeration conduction mediums such as water, air, ice, and chemicals are referred to as refrigerants.

Chilled system

This system is involved in the production of chilled water which supplied through pipe to produce air conditioning system. Asiatic has both compression & absorption type chiller system.

HVAC evolved based on

  • Technological discoveries, such as refrigeration, that were quickly adopted for food storage.
  • Economic pressures, such as the reduction in ventilation rates after the 1973 energy crisis.
  • Computerization and networking, used for sophisticated control of large complex systems serving numerous buildings.
  • Medical discoveries, such as the effects of second hand smoke on people, which influenced ventilation methods.


A warehouse management system, or WMS, is a key part of the supply chain and primarily aims to control the movement and storage of materials within a warehouse and process the associated transactions, including shipping, receiving, put away and picking. The systems also direct and optimize stock put away based on real-time information about the status of bin utilization.

Quality Assurance Department

Quality Assurance is a wide ranging concept which covers all matters which individually or collectively influence the quality of a product. It involves all the functions requred to maintain the quality during manufacturing and also the factors that influence the stability during shelf-life.


According to ISO8402 quality is defined as –

“Total of features and characteristics of a product or service that bears on its ability to satisfy a given need’’

In case of drug product Quality means:

1.      Pure

2.      Safe

3.      Effective

Quality relationships

                                      Quality Management

                                       Quality Assurance


                                          Quality Control

In ARISTOPHARMA quality comes first, profit comes to its sequence & that is reflected in its motto:

Quality – the unit we count’.

TQM (Total Quality Management) is concerned with the integration of all the efforts in the organization towards Quality improvement, Quality Development and Quality Maintenance to meet full customer satisfaction at economic levels.

                Quality, Q= P/ E


          P= Performance


So the Quality of a product should be such that it delighted the customer’s expectation.

The impact of Total Quality Maintenance (TQM)

– Better employee relation.

– Improved operating procedures.

            – Greater customer satisfaction.

– Increased financial performance.


That part of QA which ensures that products are consistently produced and controlled to the quality standards appropriate to their intended use.

Some other Key Elements of GMP

  • Sanitation and hygiene
  • Qualification and validation
  • Complaints
  • Product recalls
  • Contract Production and Analysis
  • Self-Inspection and Quality Audits

Quality Assurance (QA)

QA= Product design (Formulation to shelf-life)+ Good Manufacturing Practice (GMP)+ Quality control (testing+assessment)+ Quality.

Quality control (QC)

Quality Control is that part of GMP concerned with sampling, specification & testing, documentation & release procedures which ensure that the necessary & relevant tests are performed & the product is released for use only after ascertaining it’s quality.

Importance of Quality Control

Quality control is very much important in pharmaceutical industry. All the factors which contribute either directly or indirectly to the purity, safety, effectiveness and reliability of the product will be included under the term ‘quality’. To achieve all these characters there is need to undertake quality control.

Quality control ensures that a drug will have the following characteristics:

  • Genuine Quality as well as good nature
  • Physically and chemically pure
  • It contains same amount of ingredients as mentioned on the label
  • It must be in such a form that after administration it is effective
  • Quality in terms of shelf life/stability
  • No toxic impurities

The Q.C department performs the following major responsibilities-

  • Raw materials analyses to issue passed, reject or quarantine advice for each batch of raw
  • Material.
  • Assessment of the intermediate products for further processing
  • Assessment of bulk products for their release, reprocess, reject etc.
  • In- process quality control (IPC).
  • Control of laboratory reagents.
  • Analysis of complaint samples.
  • Preserves retention sample for exp. date + 1 year.

Steps of QC

Raw material analysis

  • Appearance.
  • Odor
  • Identification.
  • Average weight.
  • Uniformity of weight.
  • Disintegration time.
  • Melting point.
  • Solubility
  • Refractive index
  • Specific gravity
  • Moisture content

Finished product analysis

  • Appearance
  • Identification
  • Average weight of tablet
  • Hardness
  • Thickness
  • Disintegration time
  • Frability test
  • Dissolution
  • Content uniformity
  • Chemical assay


The objective of sampling and subsequent testing is to provide an effective on the quality of the product or substances being processed.

For excipient, sampling done by the following procedure :

  1. Ön+ 1 rule, where n = total number of container.
  2. 100% sampling

In Aristopharma 100% sampling is done.

Four things should be consider in sampling:

  1. Sampler
  2. Sample container
  3. Sample tools
  4. Sampling label

Routine activities

Environmental Monitoring


  • For each session – gloves is monitored (but not immediately after sanitising!)
  • Clean room operators are  regularly validated to demonstrate that they do not contaminate gowns during gowning up (gowning qualification)
  • Periodic sampling for other locations on gown


  1. Surface monitoring

–        Product contact surfaces, floors, walls, and equipment are tested on a regular basis

–        Surface monitoring is  performed at conclusion of aseptic processing (to minimise risk of contaminating critical surfaces during production)

2.Active Air Monitoring

a certain volume of air is sampled (volume and location should be meaningful)
instruments are calibrated
 3.    Passive Air Monitoring
Settle plates exposed for 30-60 minutes
Media is capable of growing a range of bacteria and moulds (e.g. Soybean Casein Digest Agar (SCDA)/Trypticase Soy Agar (TSA)
          4.  Water
microbiological quality of water  is very important
It has an extensive, comprehensive water testing programme
Feed water, pre-treatment, reverse osmosis (RO), deionized (DI), purified/highly purified and water for injection (WFI) is tested

Sterility test

Sterility test is a quality control test used as part of product release for product required to be sterile.

  • In a Grade A laminar air flow cabinet in a Grade B background it is carried out.
  • Air supply through HEPA filters, pressures should be monitored and alarmed
  • Access to area should be through airlocks
  • Soybean Casein Digest medium (SCD), (also knows as Trypticase Soy Broth(TSB)) and Fluid Thioglycollate medium (FTM) is usually used (to detect aerobic and anaerobic organisms)
  • At least 14 days incubation
  • 20-25°C for SCD/TSB, 30-35°C for FTM
  • Caso broth, Thioglycollate broth, Membrane filter, rinse fluid etc. are used to perform sterility test.

Endotoxin Testing

  • Parenteral products should be free from endotoxin
  • Endotoxin is a lipopolysaccharide present in the cell wall of gram negative bacteria which can cause fever if introduced into the body
  • Raw materials, WFI used in manufacture and some finished product is tested for endotoxin
  • LAL (Limulus Amebocyte Lysate) test is used for detecting endotoxin (previously a rabbit test) based on clotting reaction of horseshoe crab blood to endotoxin .
  • 3 hour incubation for Lal test
  • Types of LAL test – Gel Clot, Turbidimetric , Colorimetric

 Limit test

The Microbial Limit Tests are designed to perform the qualitative and quantitative estimations of specific viable microorganisms present in samples.

  • It includes tests for total viable count (bacteria and fungi) and Escherichia coli.
  • Incubation time 3-5 days
  • Limits for liquid Aerobic bacteria- 200CFU, fungus- 26 CFU,
  • Limits for cream ointment- niot more than 200CFU
  • Lactulose, aerobic microbial count- less than 100CFU

Preservative test

Preservatives are antimicrobials put into products to kill or prevent the growth of microorganisms over a relatively long period of time. Incubation time is 28 days. The typical microorganisms used for preservative challenge studies follow:

  • Pseudomonas aeruginosa: Gram-negative
  • Escherichia coli: Gram-negative bacterium,
  • Staphylococcus aureus: Gram-positive bacterium,
  • Candida albicans: Fungus (yeast),

Validation is defined as establishing document evidence, which provide a high degree of assurance that a specific process or system will consistently produce a result meeting its predetermined specification.

Validation normally required for processing, equipment’s services, production process, test procedure & computer system. The parameters, considered for the validation, are

–          Linearity

–          Accuracy (Recovering)

–          Precision (Reproducibility), etc

Validation types

A)  process validation

Depending on when it is performed in relation to production,

Validation can be prospective, concurrent, and retrospective or revalidation (repeated validation).

1.    Prospective validationProspective validation is carried out during the development stage by means of a risk analysis of the production process, Where possible critical situations are identified, the risk is evaluated, the potential causes are investigated and assessed for probability and extent, the trial plans are drawn up, and the priorities set.
2.    Concurrent validationConcurrent validation is carried out during normal production. This method is effective only if the development stage has resulted in a proper understanding of the fundamentals of the process. The first three production-scale batches must be monitored as comprehensively as possible.
3.    Retrospective validation – Retrospective validation involves the examination of past experience of production on the assumption that composition, procedures, and equipment remain unchanged; such experience and the results of in-process and final control tests are then evaluated.
4.    Revalidation- Revalidation must be performed on introduction of any changes affecting a manufacturing and/or standard procedure having a bearing on the established product performance characteristics. Such changes may include those in starting material, packaging material, manufacturing processes, equipment, in-process controls, manufacturing areas, or support systems (water, steam, etc.).

B)   Instrumentation Validation

  • This is a process necessary for any analytical laboratory.
  • Data produced by “faulty” instruments may give the appearance of valid data.
  • The frequency for calibration, re-validation and testing depends on the instrument and extent of its use in the laboratory.
  • Whenever an instrument’s performance is outside the “control limits” reports must be discontinued

Equipment records should include:

  • Name of the equipment and manufacturer
  • Model or type for identification
  • Serial number
  • Date equipment was received in the laboratory
  • Copy of manufacturers operating instruction (s)

C)  Cleaning validation

Strategy on cleaning validation

      Product contact surface

      After product changeover

      Between batches in campaigns

      Bracketing products for cleaning validation

      Periodic re-evaluation and revalidation

D)  Analytical method validation

Sensitive assay procedure:

  2. TOC
  3. pH
  4. conductivity
  5. UV
  6. ELISA

Phases of Validation

Validation is broken down into three phases:

  • Installation Qualification (IQ)
  • Operational Qualification (OQ)
  • Performance Qualification (PQ)

These three protocols are used to define tests that will demonstrate that the process consistently and repeatedly produces the desired product.

      Installation Qualification (IQ)

–        This is the first step in validation.

–        This protocol insures that the system/equipment and its components are installed correctly and to the original manufacturer’s specifications.

      Operational Qualification (OQ)

–        This step proceeds after the IQ has been performed.

–        In the OQ, tests are performed on the critical parameters of the system/process. These are usually the independent and/or manipulated variables associated with the system/equipment.

      Performance Qualification (PQ)

–        This is the third and final phase of validation.

–        This phase tests the ability of the process to perform over long periods of time within tolerance deemed acceptable.

      Design Qualification( DQ )

      – Design of the system

–     (e.g. components, type of air treatment needed, materials of construction)


      Precision, linearity, selectivity

      Limit of Detection (LOD)

      Limit of Quantitation (LOQ)

      Recovery, by spiking

      Consistency of recovery

Importance of validation is vital in pharmaceutical company. It is an quantitative approach is needed to prove quality, functionality, and performance of a pharmaceutical/biotechnological manufacturing process.
