The terminal stage of the production is packaging. This is the terminal stage at which a finished product gets a shape for marketing purpose. Proper packaging maintains the integrity of the pharmaceuticals. It should preserves drug efficacy as well as its purity, identity, potency and quality for its entire shelf life. The selection of package therefore begins with the determination of the product’s physico-chemical properties, its protective needs and marketing requirements.

Packaging materials are of two types:

  1. 1.  Primary packaging materials
  • PVC
  • Aluminum foil
  1. 2.  Secondary packaging materials
  • Printed box
  • Leaflet
  • Labels
  • Outer

Suspension is the process of preparing homogenous two phase system in which the internal or dispersed phase is solid and the external or continuous phase is liquid.

Steps of Preparation:

Carefully tare the container

Finely powder any ingredients not already in fine powder.

Mix the insoluble powder in a mortar

Adding first the ingredients of smallest bulk and diluting it with others increases order of bulk, using amount equal to the bulk already in the mortar.

Add enough vehicles to produce a smooth paste.

Add, in small amounts, any non volatile solid ingredients, dissolved in part of the vehicle, and mix well.

If necessary, dilute with the vehicle until pourable.

Examine the suspension critically.

Before use, rinse the fabric with a little vehicle to detouch loose fibers.

Strain into the tared bottle.

Add any volatile solid ingredients, previously dissolved in some of the vehicle, and mix well.

Add any liquid ingredients, rinse the measures and mix well after each edition.

Rinse the mortar and pestle with successive volumes of vehicle until they are quite clean, transferring the rinsing to the bottle.

Parenteral products:

In Rangs Pharmaceuticals Parenteral products are prepared as sterile product. As Parenteral products are given directly to systemic circulation so sterility is a must.

Environmental conditions that are maintained in sterile product manufacturing:


The air of the sterile product manufacturing area should be strictly maintained. There are some air classifications for the manufacturing area to maintain CGMP. This are-

Air Classifications

 Clean Area Classification

(0.5 um particles/ft3)



> 0.5 m particles/m3

Microbiological Active Air Action Levelsc (cfu/m3 )

Microbiological Settling Plates Action Levelsc,d (diam. 90mm; cfu/4 hours)





















 HVAC system:

HVAC is an acronym for ‘Heating ventilation and air conditioning’ system and is sometimes referred to as climate control. The system helps to control humidity and temperature of the air within a building and are responsible for maintaining pressure relationships between spaces, ensuring smoke control. HVAC system works, primarily to provide healthy and comfortable interior conditions and are well designed to perform the task with minimal energy consumption and air, water pollutant emissions.

Use of HVAC System

  Heating: Heating technology makes use of equipments such as a boilers, forced air gas furnace, heat pumps and radiant floor heat to heat the environment or interiors.

  Cooling: Cooling technology includes equipments such as central and room conditioning, chillers, desiccant dehumidifiers and absorption cooling for various buildings.

  Air ventilation and quality: This includes using equipments such as variable air volume systems (VAV), Low-pressure-drop ducting design, lowface-velocity air handlers etc for high efficiency air distribution system.

HEPA Filter:

A high efficiency particulate air or HEPAfilter is a type of high-efficiency air filter.


HEPA filters can remove at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter. Particles of this size are the most difficult to filter and are thus considered the most penetrating particle size (MPPS). Particles that are larger or smaller are filtered with even higher efficiency.

HEPA filters are composed of a mat of randomly arranged fibres. Key metrics affecting function are fibre density and diameter, and filter thickness. The air space between HEPA filter fibres is much greater than 0.3 μm. The common assumption that a HEPA filter acts like a sieve where particles smaller than the largest opening can pass through is incorrect. Just as for membrane filters, particles so large that they are as wide as the largest opening or distance between fibres cannot pass in between them at all. But HEPA filters are designed to target much smaller pollutants and particles are mainly trapped (they stick to a fibre) by one of the following three mechanisms:

Interception, where particles following a line of flow in the air stream come within one radius of a fibre and adhere to it.

  1. Impaction, where larger particles are unable to avoid fibres by following the curving contours of the air stream and are forced to embed in one of them directly; this effect increases with diminishing fibre separation and higher air flow velocity.
  2. Diffusion, an enhancing mechanism is a result of the collision with gas molecules by the smallest particles, especially those below 0.1 µm in diameter, which are thereby impeded and delayed in their path through the filter; this behaviour is similar to Brownian motion and raises the probability that a particle will be stopped by either of the two mechanisms above; it becomes dominant at lower air flow velocities.

Diffusion predominates below the 0.1 μm diameter particle size. Impaction and interception predominate above 0.4 μm. In between, near the 0.3 μm MPPS, diffusion and interception predominate.


A dehumidifier reduces the level of humidity in the air, usually for health reasons, as humid air can cause mold and mildew to grow inside homes, which has various health risks. Relative humidity is preferably 30 to 50%. Very high humidity levels are also unpleasant for human beings, can cause condensation .

In pharmaceutical industry,dehumudifier is used o control the humidity of the manufacturing area.


Air conditioners automatically act as dehumidifiers when they chill the air and thus need to handle the accumulated water as well. Newer window units use the condensing coil and fan to evaporate the accumulated water into the outdoor air, while older units simply allow the water to drip outside. Central air conditioning units need to be connected to a drain.

Laminar air flow:

An airflow moving in a single direction and in parallel layers at constant velocity from the beginning to the end of a straight line vector.

In Rangs Pharmaceuticals, the filling and sealing of  the injectables are done under the laminar air flow to control contamination.

One way entry & exit:

One way entry & exit should be maintained. Because there is a possibility of the product to be contaminated. The products are passed via the passbox from one room to another room. This is also very important to maintain the sterility of the product.

Areas of Injectables:

  • 1st change room
  • 2nd washing room
  • Final dressing room
  • Air shower
  • Material washing area
  • Liquid processing unit
  • Ampoule filling & sealing unit
  • Air lock pass box
  • Terminal sterilization

Process maintained in sterile product manufacturing unit:

  • In the previous day of manufacturing, the packaging matrialals are collected and sterilized by-

                                 Dry heat sterilization

                                 Moist heat sterilization

                                 Bun washing machine

  • To make pyrogen free of certain products, 250o c temperature is maintained for about 90 minutes.
  • In moist heat sterilization, 121o c is mainained for 20-25 minutes.
  • The production area is cleaned time to time by isopropyl alcohol.
  • In the previous day of manufacturing, fumigation is done by 50% water and 50% formaldehyde
  • The UV ray is passed over the night-before manufacturing.
  • About 45% humidity and 25o c temperature is maintained in the vial filling room.
  • After filling and sealing, the products are transformed into intermediate store area.
  • Blister packaging is done in the Rangs pharmaceuticals for injectables.

Conditions maintained in ware house:

  • For non antibiotic store, normal temperature and storage condition is maintained.
  • For antibiotic store, 15-18oc and bellow 50% humidity is maintained.
  • For cool sore, 2-8oc temperature is maintained.

GMP method for Ware house:

FIFO (first in first out) strategy is followed for the release of RM to manufacturing. Although materials are always taken from the approved source, batch no of the renders, manufacturing date, expiry date, etc are checked before entry, complete security & prevention of pilferage of every materials are confirmed.

Activities of Ware house:

  1. Initially in the ware house, the quality of the product is not checked.
  2. Only physical exam is done, which include whether he container is properly sealed.
  3. If he staffs mentioned in the invoice are present or not, if the no. of the container are   same or not.
  4. If passes kept in quarantine area
  5. The invoice date of he received is inputted in SAP
  6. From SAP, QC check if every thing is ok and a manual is also sent o QC
  7. From sampling booth the sample is sent o QC
