Necessity of in-plant training:
A pharmacist is the person of drugs or the expert on drugs. He is the only expert on drugs, for expertise regarding drugs requires knowledge in depth in all the facts of pharmacy. It is her professional responsibility to know all about the drugs. No educational program other than that in pharmacy provides the background to understand completely all about drugs.
Among the professions of pharmacists like community pharmacy, institutional pharmacy, whole sale pharmacy, industrial pharmacy, government service, pharmaceutical education, organizational management, in my country industrial pharmacy offers great opportunity to the pharmacists.
Industrial pharmacy is a profession of unique hybrid of business and profession.
So an industrial pharmacist should have proper knowledge about drugs and also about medical progress, commence marketing and technology. To be a self-sufficient pharmacist beside academic knowledge, practical knowledge is essential.
This is why after appearing the Bachelor of Pharmacy examination in-plant training was arranged by the department in renowned pharmaceuticals industries. This training has sharpened my academic knowledge what I learnt in the last four years .I have completed my training in Popular Pharmaceuticals Limited a fast growing pharmaceutical company in Bangladesh.
Popular Pharmaceuticals Limited is established in compliance to all the norms to become a Global Company. This is the only company in Bangladesh having five separate and dedicated facilities on over 6 acres of land for the manufacture of variety of formulations like Human Insulin, Low molecular wt heparin, Cephalosporin, Penicillin, Ophthalmologic, SVP, Dialysis Fluids, and LVP etc. Besides its regular formulations like solids (Tablets, Caplets, Capsules), liquids (Syrup, Suspension, powder for suspension), creams & ointments. PPL has the highest initial investment to establish the most modern, State-of-The-Art Pharmaceutical manufacturing facilities in Bangladesh and already marketed more than 150 formulations with first time introduction of a number of molecules and formulations in the country. There are also good numbers of novel products and formulations in the pipeline to be launched shortly in the market.
Popular Pharmaceuticals Ltd. (PPL) has developed its export portfolio from the very 1st year of its operation capitalizing on its strict compliance to WHO cGMP standards and initiated proceedings for export its products to the developed countries that demand stringent regulatory requirements, in addition to the less and moderately regulated countries where products from Bangladesh are currently being exported.

- 2. Aseptic Room Preparation:
The purpose of the aseptic technique is to prevent microorganisms from the environment.
To design of an aseptic room the following factors must be borne in mind:
5. Surfacing materials
The aseptic procedure comprises the following steps:
1) Sterilization of equipments
2) Sterilization of containers
3) Sterilization of gown.
4) Filling of the solution in the containers under aseptic conditions
5) Double door air lock system.
6) Pass box for materials.
Filling containers under aseptic conditions is the most critical step in the production cycle. This technique is filtration sterilization. HEPA (High Efficiency Particulate Air) filter is used. The most effective ones are claimed to retain 99.997% of the particles. Laminar Air flow cabinet is used under HEPA filter. Filling area is class-A zone whereas the background is class-B zone. The processing rooms must be supplied and flushed with air under controlled positive pressure.
- 3. Sterilization:
Sterile products can be classified in two classes:
- Products which can be sterilized in their final container.
- Products which must be processed under aseptic conditions since they cannot withstand the common methods of sterilization.
Most sterile preparations are aqueous solutions and the method of choice for sterilization is autoclave.
There are two types of sterilization:
Name of sterilization
Dry heat sterilization
250°C, 45 minutes. Glass container(vials),
18O°7 hr Closed mouth ampoule
Moist heat sterilization (Autoclave)
121°C, 30 minutes. Dress, machine parts, flips off slip, rubber stopper.
- 4. Gowning System:
In the manufacture of sterile drugs Gowning System is most important.
1) The gown must be sterilized and made of material which will not shed particles.
2) Everyone entering a clean or a sterile area must change gear garments and wear special garments which includes head, musk and footwear.
3) The number of people must be as low as possible and restricted to authorized people.
LVPL stands for large volume parenteral liquid. Popular Pharmaceuticals Ltd. produces a variety of infusion products
v Glucolin- Dextrose 5% w/v
v Glucolin DS- Dextrose 10% w/v
v Glucosal-Dextrose 5%w/v and Sodium Chloride 0.9% w/v
v Electrosal- Hartmann’s solution
v Kolosal- Cholera saline

v Civox- Ciprofloxacin 0.2% w/v
v Levobac- Levofloxacin 0.5% w/v
v Metonid- Metronidazole 0.5% w/v
Cleaning and Maintenance:
The manufacturing vessel is fitted with a mobile auto cleaning in place (CIP) and sterilization in place (SIP) unit from Pharmalab. CIP is done with 80-90 °C WFI. When filling starts the first 8 to 10 bags are rejected to make sure the cleaning WFI is fully expelled from the system.
In-Process Control: a leak test is carried out on the infusion bags by random sampling.
Quality Control (QC):
After mixing and before filtration 250ml of solution are sent to QC to test pH and weight/ml. The first and the last filled bags are sent to QC for bio-burden (endotoxin and microbiological test) .After autoclave around 23 bags goes to QC for sterility tests.
Popular infusion products use Poly propylene (PP) bags which is of better quality than the PVC bags that are widely used because the plasticizers PVC bags used have been shown to bio-accumulate and lead to reproductive problems.
Flowchart showing the manufacturing of infusions
Popular Pharmaceutical Ltd is one of the very few companies to produce Hemodialysis fluid. It currently produces 3 dialysis fluids
v Dialyte A- acidic component (pH 1.8-2.8)
v Dialyte AC- basic component (pH 8.1-9.1)
v Dialyte B – pH 7.5-8.5
Flowchart of the Dialyte manufacturing process
The primary packaging of dialyte fluids is canisters. The outside of the canister and cap is wiped with Clotech (sodium hypochlorite 5.25%). The inside of the canisters is first washed with portable water , than Clotech solution and then with hot purified water. After that they are left to dry and then they are ready to be filled.
This test is carried out to test the efficiency of the cartridge after filtration of every batch. The Bubble point test is carried out using the machine Sartocheck Junior.

Quality Assurance and Validation
Quality Assurance (QA) means that products used by consumers should fulfill the need for which it was acquired. To achieve this end, a whole gamut of organizations, methods and efforts are required. The whole process of assuring, that the quality of the product will be as stated or perceived, consistently, can be called quality assurance.
ROLE of QA
Validation may be defined as a means to prove that an equipment or process actually performs as per design or requirement. This is achieved by measuring any attribute that is possible to quantify.
Purpose of Validation: Validation is carried out to have better control of the manufacturing and related operations to ensure minimum deviations in actual production from the ones required by design. The benefit of such validation exercises therefore include better system control and maintenance and a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality characteristics.
Process Validation must have Repeatability
Meet pre-determined specifications.
In a validated process critical parameters are optimized. Each step of the manufacturing process should be qualified to validate the complete process.
Dispensing: All the used balances are calibrated. The formulation is correct and authorized. All ingredients are dispensed in front of a QA officer.
Encapsulation: Temperature and relative humidity are specified. Average and individual weights are monitored as per requirement.
Filtration: The integrity of filters is checked after completion of the filtration.
Filling/ Sealing: The condition of the room is checked by particle counters and settling plates. The particle count in Class A room should be below 100/f ³. All filling head should deliver the predetermined volumes as specified.
Packaging: Line clearance is obtained prior to start up. All the stereos used for overprinting are of the current product lot.
In-process control (IPC) is an integral part of Quality Assurance. IPC is done during the manufacturing of a product by carrying out tests to ensure certain specifications of the product are met. IPC basically guarantees that the validated process is running smoothly and the product has the desired quality. In-process controls are particularly important where a process may vary with time such as tablet weights, fill volume etc.
Manufacturing Process In-process control
a) Dispensing Room condition –Temperature
and RH should be within specifications.
b) Granulation Uniformity of the granules as well as granule
c) Drying LOD( Loss on drying)

Major responsibilities of QC:
- Sampling adequately for testing purpose.
- Issuing release, reject or quarantine advice for each batch of raw, bulk and packaging materials.
- Assessment of the finished products for their release, reject etc.
- Maintaining batch wise full quality control test records with signature of the person(s) who performs the tests.
- Batch documentation.
- Performing Environmental monitoring checks.
- Calibration and standardization of laboratory equipment.
- Control of laboratory reagents.
- Analysis of complaint samples with their corresponding keeping samples.
GLP norms and regulations:
To ensure a wide range of testing disciplines the laboratory has some facilities which are discussed in GLP.
The major considerations that accounts for GLP functioning involves:
- Organization & management:
It is a basic requirement for establishing an effective QC system.
- QC department is a well organized department. He has the authority of approval or rejection of each batch of starting, packaging and final materials on the basis of testing.
- Personnel at all levels have accountability to carry out their responsibilities to meet the quality goal.
Qualified personnel are a key factor in ensuring quality. Personnel have three important characteristics:
- 3. Premises:
A well designed premise is an essential part of GLP.
- Adequate space allocations.
- Easy to clean
- Safety facilities
- Storage facilities
- Segregation of activities
- Proper environment for testing
- Every equipment has safety distance from others
- Microbiology lab is isolated from Analytical lab
- 4. Equipments:
The laboratory is well equipped for performing all tests according to BP, USP. To maintain all equipments & machineries following measures are taken:
- Every equipment has a log book for records.
- Regular maintenance is done.
- All equipments are calibrated at specified intervals.
- Most of the equipments & machineries are connected with printers thus there remain no chance of manipulation.
5. Reference standards:
Reference standards are substances with known purity or potency. Certified reference standards are available from many official sources. For routine laboratory tests it is worth considering working standards prepared by standardizing some good quality row materials against certified reference substance.A good stock of reference standards is maintained and used.
To maintain reagents QC department has taken following initiatives:
- Laboratory has a complete list of all the reagents needed.
- Solid reagents are stored in alphabetic orders and separated from liquid reagents.
- The reagents need to be stored at low temperature is refrigerated.
- Flammable reagents have segregated area.
- Moisture sensitive reagents are stored in desiccants.
For every operation in QC written instructions are available. It has master control procedure (MCP) for every materials. It has SOP for every action. SOP is con strictly followed by analysts.
Appropriate sampling is a vital step in GLP. To facilitate correct and appropriate sampling procedures sampling must be done at conditions same as production environment e.g. sterile raw materials & products are sampled under laminar air flow.
The incoming goods and finished products are tested according to BP, USP, EP as per requirement laid down specifications.
All test results are recorded on a test record sheet (TRS). All Q.C. records relating to a batch analysis are a part of the batch documentation. The purpose of documentation is to record important information with evidence. It is preserved at least one year after batch expired date.
Quality control of raw materials:
To achieve desired goals following measures are taken:
1. Materials receiving System:
Raw materials of every batch must require with a full certificate of Analysis which is a definite binding on the part of the supplier that the materials meet the required specifications. Now a day, many reagents’ certificates are found on internet.
After receiving the raw materials, a GRN (Goods Receive Note) recorded with details such as: material’s name, supplier’s name, total quantity, number of containers, manufacturer’s batch number (s), physical condition of the containers etc.
The raw materials should remain in quarantine until sampled, tested and released or rejected by the laboratory.
It is important that the QC personnel independently inspect the raw materials during sampling.
Sampling is done by using sampling thieves. It takes materials from three positions from top, middle and bottom. If there is large numbers of containers sampling is done from √n+2 containers, where n is the no. of the containers.
3. Batch release:
The raw materials should be released in a batch fashion and with proper status labeling. Approved raw materials are marked green and available to warehouse staffs.
If the raw materials don’t comply with specifications, they are rejected and marked red label.
Control of Packaging materials:
Following characteristics are checked in packaging materials:
• Text of the printed materials.
• Color of the materials.
• Locking of cartoons.
• Compatibility of closures with bottles.
• Thickness of foils.
• Real materials are used.
• Pasting of cartoons.
• Weight (gram per m2) of cartoons for checking materials.
Control of Bulk Products:
Each lot of bulk product is tested to ensure:
Bulk products are tested following their MCP. Some products require compendial (BP/USP) procedures for testing.
Control of finished products:
Final testing of finished product is made in the quality control laboratories. The testing of finished product for compliance with predetermined standards is a critical factor for product release.

Following techniques generally employed for monitoring:
A) Airborne particle count (non-microbiological):
This is done by using particle counter.
B) Settle plate technique:
Petridishes containing sterile microbiological growth media in agar are exposed to production area. Then it is incubated for 5 days at 30°c. This visualize the microbial growth.
C) Surface swabs technique:
Sterilized swabs of cotton buds are moistened in a sterile diluent’s or a suitable liquid culture media. A specific area is then swabbed and the organism sampled from the surface is then smoothly rubbed over the supporting agar surface and incubated. This technique is employed to evaluate solid surface, garments, equipment, personnel for microbiological growth.
D) Air sampling:
Done for microbial growth in air.
Airborne particle limit:

A) Sterility test:
It is done for raw materials and product materials. 14 days are require for sterility test.
a) Direct method.
b) Filtration method (mostly used).
Condition require for microorganism test given below:
Type of Organism
22°C – 25°C
30°C – 35°C
B) Limit test/Contamination test:
This test is done for checking raw materials. Three types:
1) Pour plate
2) Spread plate.
C) Endotoxin test/LAL test:
It is an in-vitro test method for pyrogen, has been developed utilizing the gelling property of the lysate of amoebocytes of limulus polyphemus.
Warehouse is the place where the bulk raw materials, packaging materials as well as finished products are kept at their optimum storage condition. Raw materials are tested as they enter the warehouse and they are transferred to the manufacturing department by requisitions.
Materials Receiving System:
a) Upon receiving the shipment’s labeling should be carefully checked to make sure that they belong to the same batch. Only materials from the same batch receive the same Good receival note (GRN) number. The GRN is the identification number for that raw material.
b) The shipment should be inspected visually for damage.
c) The materials are than carefully labeled ‘Quarantine’ with the GRN number.
d) The first people allowed opening the material labeled ‘Quarantine’ are Quality Control (QC) officials. For active pharmaceutical ingredients QC takes samples from each and every container. However for excipients as well as packaging material the sampling is done √n +2. The containers from which the QC has sampled are labeled ‘sampled’.
e) After the materials have conformed with the specification they are released by QC authorities and are labeled ‘released’ meaning they are ready to be used in manufacturing.
f) Rejected materials should be clearly separated from the ‘released’ materials. Rejected packaging materials containing the company’s logo are destroyed. For raw materials that are the rejected the vendor is contacted immediately.
Raw materials and finished products are stored according to their chemical or physical properties. Some raw materials and finished products are kept at normal room condition whereas products which are temperature sensitive are kept in
- Cold room (2-8°C) eg. insulin
- cool room (8-15°C)
Finished products such as solid dosage forms are kept under lock and key.
Pethidin containing product, because of the risk of abuse, is kept under strict lock and key and access is restricted to authorized personnel only.
In order to prevent mix-up of printed containers and labeling materials, each printed packaging material is stored properly identified with the specific GRN number and code number and at the time issues the identity is checked very carefully.
Close attention is paid to dangers of cross-contamination. Dispensing of raw materials are done in the presence of an authorized personnel from production and QA.
Materials are dispensed according to the Batch manufacturing record (BMR). The remaining stock is recorded to make reconciliation of the stock possible at any time.
During dispensing QA officer also checks the room condition to make sure the humidity and temperature are optimum for the raw material .Dispensing is done under laminar air flow to minimize dust generation and microbial contamination. All raw materials are dispensed in a ‘First-Expiry-First-Out(FEFO)’ basis.
Product Development (PD) is the department that is a responsible for the effective formulation of a drug. The stability, efficacy of a drug depends on its formulation. PD consists of two parts: Galenical & Analytical. PD is also responsible for creating BMR and BPR.
Launching a new product involves a lot of work.
During formulation PD has to undertaken intensive research. Literatures have to be searched for
- Stability assay, key solubility data
- Bulk properties, solubility and stability profile and compatibility
PD also has to do process research to
- Improve yield
- Bulk scale-up
And finally from an experienced trial-and –error method a formulation is developed.
Lab Batch: a lab batch is produced to see if the formulation is effective. The recipe of the lab batch is sent to the DRA. It is also done for a feasibility study. The lab batch recipe undergoes various corrections.
Pilot Batch: The manufacturing procedure should be validated on at least three pilot lots to identify the critical parameters in the product and process. Tentative limits fixed for
the critical variables may be modified from the data available by stability studies.
There are two methods by which stability is tested: Real-time stability study, and Accelerated stability study.
Products are kept in the stability chamber at three different conditions:
25°C, 60% Relative Humidity (RH)
a) Real time stability
30°C, 65% RH
b) Accelerated Stability: 40°C, 75%RH
The product stays in the stability chamber for 6 months. If the degradation of the product is less than 5% in 6 months then the shelf life is 2 years
The Analytical method development requires demonstration of suitable
Water is pulled 470 feet below ground by a submersible pump. The water is then chlorinated to destroy bacteria and filtered through a multimedia filter. USP 28/27 quality Portable Water is produced.
Portable water is further treated to produce purified water which is used in manufacturing & cleaning processes. The purified water pipes are cleaned by hot water sterilization at 85°C for 30 to 35 minutes every 15 days to take the microbial count to 0 cfu/ml. At the point of feed at PW sodium hypochlorite is dosed.

Effluent Treatment System
The purpose of an Effluent Treatment Plant (ETP) is to reduce Biological Oxygen Demand (BOD) & Chemical Oxygen Demand(COD) of pharmaceutical unused chemicals & powders and waste materials which may cause severe harmful effect on environment as well as human health.
Effiuent management in Popular Pharmaceuticals Ltd. is carried out through bio-spiral technology as aerobic treatment process. The capacity of the plant is 30 m3/day.The quality of output is dischargeable into the public sewer or re-useable for gardening & land scarping.
All the waste water passing through a bar screen is collected. Raw sewage from the source is usually received in to the bar screen chamber by gravity. Screen provide will remove all floating and big size matter such as plastic bottles, polythene bags, glasses, stones etc.
Sewage transfer pumps transfer sewage from equalization tank to bio-spiral unit.
The Primary Settlement zone reduces the suspended solids by 75% and the BOD by 25% to 30%. The recirculation from the system and the return of humus sludge into the primary settlement zone inhibits the settled effluent from becoming anaerobic which prevents bad odor.
▪Aerobic Treatment (Reducing Process of BOD & COD):
The primary settled sewage is then treated by the Aerator. It is a biological treatment zone. It is a combined fixed film reactor and active aeration system mounted on a horizontal shaft. The Aerator is fitted on the sludge storage tank and covered. The rotational media is a spiral formation enclosed in an outer drum to provide active aeration.
The final settlement or humus tank is a discrete compartment denying ingrees of untreated or partially treated liquor. Treated sewage is then passed to Treated Sewage Tank and the sludge goes to the Sludge holding Tank.
▪Sludge Holding Tank:
Sludge Holding Tank is provided in the base of units. It’s capacity is approximately 12 weeks capacity provided. De-sludging from the holding tank can be carried out by centrifugal pump.
Total suspended solids (TSS): NMT 150ppm
Total dissolved solids (TDS): NMT 100mg/L
Chemical oxygen demand (COD): NMT 200mg/L
Biological oxygen demand (BOD): NMT 30mg/L

The overall tasks of the factory administration are as follows:
- House keeping: means keeping the whole administration unit as well as the premise clean and attractive looking. The support staff deployed for this purpose is responsible for many a things starting from gardening to keeping the washrooms clean.
- Canteen management: the company has a yearly contact with a caterer who supplies meals as well as snacks. The raw food that is brought in every day is checked by supervisors to ensure desired quality.
- Safety and security: The Company has its own security personnel. It currently has 1 inspector, 5 supervisors and 13 well-trained guards. The guards work on around the clock in 3 shifts; from 6 am to 2 pm, from 2pm to 10 pm and from 10pm to 6 am. There are 7 posts around the premise where a guard is deployed. For safety there are fire extinguishers and water hoses at specific location as well as emergency exits for safe evacuation.
- Vehicle management: the vehicles work on a fixed pickup and drop schedule. They are routinely maintained at fixed workshops.
- Event management: basically consists of inviting reputed doctors, other pharmaceuticals as well people from regulatory bodies to the plant. This helps to build a lasting reputation for the company.
- Documentation: the factory administration is in charge of renewing licenses such as warehouse license, environment clearance, boiler license, trade license, taxes (city corporation tax, land tax, holding tax etc).
- Protocol: the administration looks over the visas, accommodation, and transportation of international bodies that want to visit the plant.
- Waste Management: Pharmaceutical industries are in the Orange B and Red category which means that the waste they produce can cause significant environmental damage. Thus waste management is carried out to ensure that the wastes are properly separated, recycled and disposed to maintain a pollution free environment according to regulatory requirements.
All employees working at the plant are expected to follow the factory rules and norms. The rules and norms consist of the working hours, overtime, employee’s behavior, clothing etc.
• Casual leave -10 days annually
• Annual leave- 15days
• Sick leave (14 days/year)
• Maternity leave (up to 2 children) – 16 weeks
Waste is of two types –solid waste and liquid waste. By assessing various parameters regulatory authorities have defined waste to be of two kinds- non-hazardous waste and hazardous waste.
Solid wastes are usually papers, boxes, cartons, empty blisters, glass bottles, vials, ampoules, plastic and HDPE containers, canteen wastes. They may also be metal and wooden scrapes from packaging air filters, scrapes of rubber, plastic, nylon, teflon, acrylic, GP sheet, SS sheet, GI & MS piping from maintenance.
Liquid wastes are usually cleaning and washing liquid, reagents, solvents, printing ink, lubricants from generator, air compressor, gearbox of different machinery, diesel from generator.
Solid wastes are firstly separated into wastes that can be recycled, that can be incinerated, that are hazardous and that can be sold. As Popular does not have an incinerator, incineration is carried out by a third party. Non-hazardous waste is sold off. Hazardous wastes are buried.
Liquid wastes from production are sent off to ETP. Normal container rinsing, sewerage water directly discharge into the municipal drain.
General Security Instruction:
a) Entry of unauthorized people is restricted.
b) Entry of transport inside plant is restricted except up to transport parking area. However, entry of transport during rain is allowed only to drop/pickup their persons.
c) No one is allowed to enter inside the Production areas except any cause of fire or any accident.
