Parenteral Route
 It is an route of administration other than the oral route, this route of administration bypasses
the alimentary canal.
 It includes, I.V., I. M., Subcutaneous route for parenteral administration.

Advantages
 Quick onset of action and site specific or targeted activity.
 It can prevent problem of first pass metabolism or presystolic metabolism.
 Useful for unconscious or vomiting or diarrhea patients.
 Duration of action can be prolonged by modifying formulation.
 Suitable for the drugs which are inactivated in GIT or HCl (GI fluid).

Dis-Advantages

Air Handling System (Central Air-Conditioning)

Airborne particulate classification for manufacture of sterile products

Types of operations to be carried out in the various grades for aseptic preparations

Types of operations to be carried out in the various grades for terminally sterilized products

Recommended limits for microbiological monitoring of clean areas “in
operation”

The air classification limits stated by USFDA

Critical Area

ISO 14644-1 Cleanroom Standards

• Biological indicators (BIs) are the most accepted means of monitoring the sterilization process
because they directly determine whether the most resistant microorganisms (e.g., Geobacillus
or Bacillus species) are present rather than merely determine whether the physical and
chemical conditions necessary for sterilization are met.
• Because spores used in BIs are more resistant and present in greater numbers than are the
common microbial contaminants found on patient care equipment, an inactivated BI indicates
that other potential pathogens in the load have also been killed.
Biological indicators (BIs)

Biological indicators (BIs)

• Biological indicators (BIs) are used for determination of Bacillus
species.
• BIs such as, ethylene oxide, ethylene chlorohydrin, ethylene hydroxide
and halogenated ethylenehydrine.
• BIs was determined by Z value and D Value.

Z value and D Value
 Z value is define as Temperature is required to higher death rate.
 D value is define as reduction of microbial population by 90 % of the factor 10.
 D value is 10 factor greater than Z value.
 e.g. D value is 121 ºc as the Z value is 10 ºc.

Sterile area: the area which are used to kill the all microorganisms.
Techniques
• Celerity study
• Sterility study
• Leakage study
• Pyrogen study
• LAL test
• Assay for content uniformity study

Aseptic area: the area which are used to kill the pathogenic microorganisms.
Techniques:
• HEPA filter integrity test
• Air flow pattern
• Air velocity study
• Heat sensitization study
• Heat distribution study

Quality Control of Parenteral Preparations

 Quality Assurance The planned and systematic activities implemented in a quality system so
that quality requirements for a product or service will be fulfilled.
 Quality Control is a procedure or set of procedures intended to ensure that a manufactured
product or performed service adheres to a defined set of quality criteria or meets the
requirements of the client or customer.

In Process Quality Control Test
 Conductivity measurement
 Volume filled
 Temperature for heat sterilized product
 Environmental control tests
 Visual inspection

Environmental Control
 Traffic control
 Surface disinfection personnel
 Air control (HEPA filters)

Volume Filled
An injection container is filled with a volume in slight excess of the labeled size
Determination of filled volume:
 10 mL or more 1 container
 3-10 mL 3 containers
 Less than 3 mL 5 containers

Leakage Test
 visual inspection
 bubble test
 dye tests
 vacuum ionization test

Clarity Test
 Clarity test is carried out to check the particulate matter in the sample.
 It is practically impossible that every unit of lost is perfectly free from visible particulate matter
, that is ,from particles that are 30 to 40 micrometer and large in size.
USP limits for large volume infusions
Particle size Particle limit
10 mm (or) larger/ml 50
25 mm (or) larger/ml 5

Instrumental Methods
This is also called as the particle count method particle counting may be based on
any one of the following principles; change in
Electrical resistance
Light absorption
Light scattering

Sterility Test

Methods For Testing
1. Membrane Filtration Method 2. Direct Inoculation Method

 MEDIA SUITABLE FOR STERILITY TESTS ARE:
i. FLUID THIOGLYCOLLATE MEDIUM
ii. SOYA-BEAN CASEIN DIGEST MEDIUM
WASH THE FILTERS WITH FLUIDS TO REMOVE
INHIBITORY PROPERTIES, CUTTING THE
MEMBRANES ASEPTICALLY INTO EQUAL
PARTS AND TRANSFERRING ONE OF THE
PARTS TO EACH TYPE OF CULTURE MEDIUM
USED.
THE MEDIAARE THEN INCUBATED UNDER
PRESCRIBED CONDITIONS.
Membrane Filtration

Culture Medium
• This Method Is Only Used When
Membrane Filtration Is Not Possible The
Sample Is Inoculated Directly Into The
Media Or The Device Is Placed Directly
Into The Media.
• Result:
• If No Growth In The Media Then Test Is
Positive.

Lyophilization or freeze drying
o Lyophilization or freeze drying is a process in which water is removed from a product after it is
frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor
without passing through a liquid phase.
o The process consists of three separate, unique, and interdependent processes;
Freezing,
Primary drying (sublimation), and
Secondary drying (desorption).

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.

The Lyophilization process generally includes the following steps
 Dissolving the drug and excipients in a suitable solvent, generally water for injection (WFI).
 Sterilizing the bulk solution by passing it through a 0.22 micron bacteria-retentive filter.
 Filling into individual sterile containers and partially stoppering the containers under aseptic
conditions.
 Transporting the partially stoppered containers to the lyophilizer and loading into the chamber
under aseptic conditions.

 Freezing the solution by placing the partially stoppered containers on cooled shelves in a
freeze-drying chamber or pre-freezing in another chamber.
 Applying a vacuum to the chamber and heating the shelves in order to evaporate the water
from the frozen state.
 Complete stoppering of the vials usually by hydraulic or screw rod stoppering mechanisms
installed in the lyophilizers.

 There are many new parenteral products, including anti-infectives, biotechnology derived
products, and in-vitro diagnostics which are manufactured as lyophilized products.
 Additionally, inspections have disclosed potency, sterility and stability problems associated
with the manufacture and control of lyophilized products.
