Parenterals Sterile
 pyrogen-free preparations intended for
administration by injection under or
 through one or more layers of skin or mucous
membranes
– TYPES-
– 1) Small Volume Parenterals - Volume ranges
from 1-30 ml . May be given single dose or
multiple dose.
– 2) Large Volume Parenterals- Volume ranges
from 100-1000 ml. Mostly given as single dose.
Small volume parenteral
Usually range 1-30 ml in volume.
 Mostly given as multiple doses.
Different types are:
1. Ampules
2. Vials
3. Dry powders
4. Prefilled syringes
Ampules
 Sealed glass containers with an elongated neck that must be
broken off.
 Most ampules are weakened around the neck for easy
breaking; these will have a coloured band around the neck.
 A 5 micron filter needle should be used when drawing the
contents of an ampule into a syringe since glass particles may
have fallen inside the ampule when the top was snapped off.
 In addition, it is useful to wrap an alcohol wipe or small piece
of gauze around the top of the ampule before breaking it. This
will provide some protection to the fingers if the ampule
shatters and will also reduce the possibility of glass splinters
becoming airborne
Ampules
Vials
 Drugs and other additives are packaged in vials either as
liquids or lyophilized
 powders.
 Made of glass or plastic and are sealed with a rubber
stopper.
 A needle is used to add contents to or withdraw contents
from the vial.
 Before withdrawing contents from a vial, an equal volume
of air is usually injected into the vial to pressurize the vial
and aid in withdrawing the contents.
 Vials may be designated for single-dose or multi-dose use.
 Multi-dose vials contain a preservative to inhibit bacterial
contamination once the vial has been used
Vials
Dry powders
 Dry powder formulations are lyophilized or freeze-dried
powders that must be reconstituted with some suitable solvent
to make a liquid formulation before being withdrawn from
the vial.
 Some drugs are not stable in liquid form and so these drugs
are put into the powder form and reconstituted just prior to
use.
 There are several solvents that might be used to reconstitute
the dry powders; The most common solvents are Sterile Water
for Injection, Bacteriostatic Water for Injection, Sodium
Chloride Injection etc.
Prefilled syringes
 It consists of syringes which are prefilled with the drug solution.
 There are two varieties of prefilled syringes. One type, a cartridge
type package, is a single syringe and needle unit which is to be
placed in a special holder before use.
 Once the syringe and needle unit is used, they are discarded but
the holder is used again with a new unit.
 The other type of prefilled syringe consists of a glass tube closed at
both ends with rubber stoppers. The prefilled tube is placed into a
specially designed syringe that has a needle attached to it.
 After using this type or prefilled syringe, all of the pieces are
discarded.
Prefilled syringes
Formulation aspectes
1. Water for Injection (WFI)
2. Solutes
3. Added substances
4. Antimicrobial agents
5. Antioxidants
6. Pyrogens
7. Sterilization
Water for injection (WFI)
 Sterile Water for Injection, USP is a sterile, non-pyrogenic
preparation of water for injection which contains no
bacteriostatic, antimicrobial agent or added buffer and is
supplied only in single dose containers to dilute or dissolve
drugs for injection.
 According to USP, it contains 10 CFU/100 ml water.
 For IV injection, add sufficient amount to a solute to make an
approximately isotonic solution-pH 5.0 to 7.0.
 No therapeutic activity and non-toxic.
 Water purified by reverse osmosis and distillation.
SOLUTES:
1. Added to give good stability and efficacy to the
preparation.
2. Eg. Sucrose, Mannitol, Lactose.
ADDED SUBSTANCES:
1. All substances that can safeguard quality of
preparation.
2. It may affect the solubility of the preparation,
provide a preservative effect and enhance
isotonicity.
 ANTIMICROBIAL AGENTS
1. Eg. Phenol 0.5% w/v
 ANTIOXIDANTS:
1. To preserve products because of the ease with
which many drugs get oxidized.
2. Eg. Sodium bisulphite 0.1%
 BUFFERS:
1. To stabilize pH.
2. Eg.. Citrates,
3. acetates
PYROGENS
 Metabolic products of microbial growth causing an increase in
body temperature.
 Come from sources like solvent, medicament, apparatus and
improper storage.
 It is very difficult to remove pyrogens because they are:
1) Thermostable
2) Water soluble
3) Unaffected by common bactericides.
 The bacterial substance lipopolysaccharide (LPS) in the cell
wall of bacteria is an example of pyrogen.
STERLIZATION
1. Moist heat sterilization
2. Dry heat sterilization
3. Sterilization by filtration
4. Gas sterilization
5. Sterilization by ionizing radiation
STERLIZATION
instrumentes
MOIST HEAT
STERILIZATION
 Bacterial death by moist heat is due to denaturation and coagulation of essential protein
molecules (enzymes) and cell constituents.
 It can be used for a large number of injections, ophthalmic solutions etc.
 Methods used:
1) Autoclave
2) Tyndallization
 Autoclaving used to sterilize anything, which is not injured by steam and high
 temperature of sterilization. These include aqueous parenteral solutions e.g.
 distilled water, saline solutions etc.
 Tyndallisation essentially consists of heating the substance to boiling point (or just a little
below boiling point) and holding it there for 15 minutes, three days in succession. After
each heating, the resting period will allow spores that have survived to germinate into
bacterial cells; these cells will be killed by the next day's heating.
DRY HEAT
STERILIZATION
 The killing of microorganisms by heat is a function of the time-temperature
combination used. If the temperature is increased then the time required for
killing all the bacteria will be decreased.
 The vital constituents of cells such as proteins (enzymes) and nucleic acids
are denatured by oxidation Cycles recommended as per BP 1988 are:
 A minimum of 1800C for not less than 30 minutes.
 A minimum of 1700 C for not less than 1 hour.
 A minimum of 1600 C for not less than 2 hours.
 Dry heat is used to sterilize glass ware( e.g. test tubes, petri dishes, flasks,
glass syringes etc. )
HOT AIR OVEN
STERILIZATION BY
FILTRATION
 This method is used for sterilizing thermo-labile solutions, which will
otherwise be degraded by other conventional heating methods.
 The drug solutions are passed through the sterile bacteria proof filter unit and
subsequently transferring the product aseptically into the sterile containers
which are then sealed.
 Different types are :
1) Sintered glass filter
2) Seitz filter
3) Ceramic filter
 They are suitable for sterilizing aqueous and oily solutions but not for organic
solvents such as alcohol, chloroform etc.

GAS STERILIZATION
This process involves exposure of materials to
sterilizing gases such as ethylene oxide,
formaldehyde, glutaraldehyde, propylene oxide.
Ethylene oxide is the only gas that is successfully used
on a large scale of industrial and medical
applications.
 It works by alkylation
RADIATION
STERILIZATION
 Different types of radiation used for sterilization are
1) Ultraviolet radiation
2) Gamma radiation
3) Infrared radiation
4) X-rays
5) Alpha and beta radiation
 Only a narrow range of wavelength (220 to 280 nm) of UV is effective in killing
micro-organisms, and wavelengths close to 253.7 nm are the most effective.
 Radiation from the radioactive isotope of Cobalt 60, is used as a source of gamma
emission.
 Radiation sterilization causes damage to DNA and results in cell death

CONTROLS
1. Leaker's Test
2. Sterility Test
3. Clarity Test
4. Pyrogen Test
Leaker's Test
1. It is performed by completely submerging the
sealed ampule in a deeply coloured dye
solution.
2. Generally 1% methylene blue solution is used.
3. The ampules if not sealed properly, the dye
solution present outside the ampules will
enter into the ampules and make the solution
coloured
Clarity Test
1. The parenteral product to be evaluated is
placed against a white and black background
with the contents set in motion in swirling
action.
2. It is kept in that motion until any particle
becomes visible or not.
3. Care is to be taken to avoid any air bubbles.
STERLITY TEST
 Important to check if the product meets the
requirements of sterility according to the
official books or not.
 2 methods:
 The direct transfer of the samples to sterile
culture media.The membrane filtration
procedure.
PYROGEN TEST
 Samples of production batch are tested in rabbits for the presence of pyrogens.
2 stages:
1) Sham test
2) Main test
1) Sham test:
 If the animals are being used for the first time in pyrogen testing, then condition the
 animals for 1-3 days by injecting 10 mg/kg body weight of pyrogen free solution IV.
 Maintain animals like that for 18 hrs in room maintained at a temp of 3ºC.
 Record the temperature of the animals beginning at least 90 mins before injection
and continuing for 3 hrs after injection.
 Any animal showing variation of 0.6ºC or more must not be used for main test
 Main Test:
 Determine the control temperature of each rabbit by recording the
temperature not more than 30 mins prior to injection of test solution.
 Inject into an ear vein of each rabbit 10 ml of the test solution per kg body
weight, completing each injection within 10 mins after start of
administration.
 The test solution must be warmed upto 37±2ºC.
 Record the temperatures at 1, 2 and 3 hrs subsequent to the injection.
 Following are the requirements for passing the test:
 1) Individual rise in temperature of 0.6ºC with respect to control and sum
of 3
 individual rabbits does not exceed 1.4ºC, the sample passes the test.
 2) If anything above the above mentioned requirements, continue the test
with 5 other rabbits.
 3)Individual rise in temperature not more that 0.6ºC and sum of all eight
does not exceed 3.7ºC, the sample passes the test

Small volume prentrals

  • 1. Small volume parenterals PRESENTED BY MR.AMIT H.KANSE. (M. PHARM ) RAJGAD DNYANPEETH COLLEGE OF PHARMACY BHOR,PUNE. QUALITY ASSURANCE TECHNIQUES 2017-2018
  • 2. Parenterals Sterile  pyrogen-free preparations intended for administration by injection under or  through one or more layers of skin or mucous membranes – TYPES- – 1) Small Volume Parenterals - Volume ranges from 1-30 ml . May be given single dose or multiple dose. – 2) Large Volume Parenterals- Volume ranges from 100-1000 ml. Mostly given as single dose.
  • 3. Small volume parenteral Usually range 1-30 ml in volume.  Mostly given as multiple doses. Different types are: 1. Ampules 2. Vials 3. Dry powders 4. Prefilled syringes
  • 4. Ampules  Sealed glass containers with an elongated neck that must be broken off.  Most ampules are weakened around the neck for easy breaking; these will have a coloured band around the neck.  A 5 micron filter needle should be used when drawing the contents of an ampule into a syringe since glass particles may have fallen inside the ampule when the top was snapped off.  In addition, it is useful to wrap an alcohol wipe or small piece of gauze around the top of the ampule before breaking it. This will provide some protection to the fingers if the ampule shatters and will also reduce the possibility of glass splinters becoming airborne
  • 6. Vials  Drugs and other additives are packaged in vials either as liquids or lyophilized  powders.  Made of glass or plastic and are sealed with a rubber stopper.  A needle is used to add contents to or withdraw contents from the vial.  Before withdrawing contents from a vial, an equal volume of air is usually injected into the vial to pressurize the vial and aid in withdrawing the contents.  Vials may be designated for single-dose or multi-dose use.  Multi-dose vials contain a preservative to inhibit bacterial contamination once the vial has been used
  • 8. Dry powders  Dry powder formulations are lyophilized or freeze-dried powders that must be reconstituted with some suitable solvent to make a liquid formulation before being withdrawn from the vial.  Some drugs are not stable in liquid form and so these drugs are put into the powder form and reconstituted just prior to use.  There are several solvents that might be used to reconstitute the dry powders; The most common solvents are Sterile Water for Injection, Bacteriostatic Water for Injection, Sodium Chloride Injection etc.
  • 9. Prefilled syringes  It consists of syringes which are prefilled with the drug solution.  There are two varieties of prefilled syringes. One type, a cartridge type package, is a single syringe and needle unit which is to be placed in a special holder before use.  Once the syringe and needle unit is used, they are discarded but the holder is used again with a new unit.  The other type of prefilled syringe consists of a glass tube closed at both ends with rubber stoppers. The prefilled tube is placed into a specially designed syringe that has a needle attached to it.  After using this type or prefilled syringe, all of the pieces are discarded.
  • 11. Formulation aspectes 1. Water for Injection (WFI) 2. Solutes 3. Added substances 4. Antimicrobial agents 5. Antioxidants 6. Pyrogens 7. Sterilization
  • 12. Water for injection (WFI)  Sterile Water for Injection, USP is a sterile, non-pyrogenic preparation of water for injection which contains no bacteriostatic, antimicrobial agent or added buffer and is supplied only in single dose containers to dilute or dissolve drugs for injection.  According to USP, it contains 10 CFU/100 ml water.  For IV injection, add sufficient amount to a solute to make an approximately isotonic solution-pH 5.0 to 7.0.  No therapeutic activity and non-toxic.  Water purified by reverse osmosis and distillation.
  • 13. SOLUTES: 1. Added to give good stability and efficacy to the preparation. 2. Eg. Sucrose, Mannitol, Lactose. ADDED SUBSTANCES: 1. All substances that can safeguard quality of preparation. 2. It may affect the solubility of the preparation, provide a preservative effect and enhance isotonicity.  ANTIMICROBIAL AGENTS 1. Eg. Phenol 0.5% w/v
  • 14.  ANTIOXIDANTS: 1. To preserve products because of the ease with which many drugs get oxidized. 2. Eg. Sodium bisulphite 0.1%  BUFFERS: 1. To stabilize pH. 2. Eg.. Citrates, 3. acetates
  • 15. PYROGENS  Metabolic products of microbial growth causing an increase in body temperature.  Come from sources like solvent, medicament, apparatus and improper storage.  It is very difficult to remove pyrogens because they are: 1) Thermostable 2) Water soluble 3) Unaffected by common bactericides.  The bacterial substance lipopolysaccharide (LPS) in the cell wall of bacteria is an example of pyrogen.
  • 16. STERLIZATION 1. Moist heat sterilization 2. Dry heat sterilization 3. Sterilization by filtration 4. Gas sterilization 5. Sterilization by ionizing radiation
  • 18. MOIST HEAT STERILIZATION  Bacterial death by moist heat is due to denaturation and coagulation of essential protein molecules (enzymes) and cell constituents.  It can be used for a large number of injections, ophthalmic solutions etc.  Methods used: 1) Autoclave 2) Tyndallization  Autoclaving used to sterilize anything, which is not injured by steam and high  temperature of sterilization. These include aqueous parenteral solutions e.g.  distilled water, saline solutions etc.  Tyndallisation essentially consists of heating the substance to boiling point (or just a little below boiling point) and holding it there for 15 minutes, three days in succession. After each heating, the resting period will allow spores that have survived to germinate into bacterial cells; these cells will be killed by the next day's heating.
  • 19. DRY HEAT STERILIZATION  The killing of microorganisms by heat is a function of the time-temperature combination used. If the temperature is increased then the time required for killing all the bacteria will be decreased.  The vital constituents of cells such as proteins (enzymes) and nucleic acids are denatured by oxidation Cycles recommended as per BP 1988 are:  A minimum of 1800C for not less than 30 minutes.  A minimum of 1700 C for not less than 1 hour.  A minimum of 1600 C for not less than 2 hours.  Dry heat is used to sterilize glass ware( e.g. test tubes, petri dishes, flasks, glass syringes etc. )
  • 21. STERILIZATION BY FILTRATION  This method is used for sterilizing thermo-labile solutions, which will otherwise be degraded by other conventional heating methods.  The drug solutions are passed through the sterile bacteria proof filter unit and subsequently transferring the product aseptically into the sterile containers which are then sealed.  Different types are : 1) Sintered glass filter 2) Seitz filter 3) Ceramic filter  They are suitable for sterilizing aqueous and oily solutions but not for organic solvents such as alcohol, chloroform etc.
  • 24. GAS STERILIZATION This process involves exposure of materials to sterilizing gases such as ethylene oxide, formaldehyde, glutaraldehyde, propylene oxide. Ethylene oxide is the only gas that is successfully used on a large scale of industrial and medical applications.  It works by alkylation
  • 25. RADIATION STERILIZATION  Different types of radiation used for sterilization are 1) Ultraviolet radiation 2) Gamma radiation 3) Infrared radiation 4) X-rays 5) Alpha and beta radiation  Only a narrow range of wavelength (220 to 280 nm) of UV is effective in killing micro-organisms, and wavelengths close to 253.7 nm are the most effective.  Radiation from the radioactive isotope of Cobalt 60, is used as a source of gamma emission.  Radiation sterilization causes damage to DNA and results in cell death
  • 27. CONTROLS 1. Leaker's Test 2. Sterility Test 3. Clarity Test 4. Pyrogen Test
  • 28. Leaker's Test 1. It is performed by completely submerging the sealed ampule in a deeply coloured dye solution. 2. Generally 1% methylene blue solution is used. 3. The ampules if not sealed properly, the dye solution present outside the ampules will enter into the ampules and make the solution coloured
  • 29. Clarity Test 1. The parenteral product to be evaluated is placed against a white and black background with the contents set in motion in swirling action. 2. It is kept in that motion until any particle becomes visible or not. 3. Care is to be taken to avoid any air bubbles.
  • 30. STERLITY TEST  Important to check if the product meets the requirements of sterility according to the official books or not.  2 methods:  The direct transfer of the samples to sterile culture media.The membrane filtration procedure.
  • 31. PYROGEN TEST  Samples of production batch are tested in rabbits for the presence of pyrogens. 2 stages: 1) Sham test 2) Main test 1) Sham test:  If the animals are being used for the first time in pyrogen testing, then condition the  animals for 1-3 days by injecting 10 mg/kg body weight of pyrogen free solution IV.  Maintain animals like that for 18 hrs in room maintained at a temp of 3ºC.  Record the temperature of the animals beginning at least 90 mins before injection and continuing for 3 hrs after injection.  Any animal showing variation of 0.6ºC or more must not be used for main test
  • 32.  Main Test:  Determine the control temperature of each rabbit by recording the temperature not more than 30 mins prior to injection of test solution.  Inject into an ear vein of each rabbit 10 ml of the test solution per kg body weight, completing each injection within 10 mins after start of administration.  The test solution must be warmed upto 37±2ºC.  Record the temperatures at 1, 2 and 3 hrs subsequent to the injection.  Following are the requirements for passing the test:  1) Individual rise in temperature of 0.6ºC with respect to control and sum of 3  individual rabbits does not exceed 1.4ºC, the sample passes the test.  2) If anything above the above mentioned requirements, continue the test with 5 other rabbits.  3)Individual rise in temperature not more that 0.6ºC and sum of all eight does not exceed 3.7ºC, the sample passes the test
