Conclusion
OBJECTIVES
Use of living
systems, organisms, or parts of organisms
to manipulate in the genetic level
to develop products,
systems or environme
nts to benefit

LOG
Y
produce new
substances or
perform new
functions
to modify the
genetic material of living
cells

biotechnical
methods
BIOTECH PRODUCTS
Methods to produce biotech products
• Recombinant DNA technology
• Fermentation• Tissue or cell culture
technology• Genetic engineering
EXAMPLES
•Avastin
Antibody
•Orencia
Fusion protein
•Leukine
Progenitor cells
stimulator
ROUTES OF ADMINISTRATION OF BIOTECH
PRODUCTS
Parenteral route
Oral route
Nasal route
Trans-mucosal
route
Parenteral Routeof Administration
• Intravenous
IV
• Intramuscular
IM
• Subcutaneous
SC
Intravenous Administration
Fastest way
Directly in one of superficial vein
Highest concentration can be achieved
ExampleAlteplaseReteplas
eTenectepl
ase
common with biotechnology-derived drugs,
particularly those used to treat chronic
conditions
Administered as a bolus into the
subcutis
the layer of skin directly below the
dermis and epidermis, collectively
referred to as the cutis
Subcutaneous Administration
Example Rheumatoid
Arthritis Products
Etanercept
Anakinra
Adalimumab
Insulin and hormones
administered as
subcutaneous injection
INTRAMASCULAR ADMINISTRATION
• Intramuscular administration of biotechnology-derived drugs is also commonly seen
• A technique used to deliver a medication deep into the muscles
• e.g. interferon β products have been shown to be less immunogenic when administered via intramuscular injection.
Adv
anta
ges Rapid administration of
solution
Avoids first pass metabolism
100% bioavailablePrevent the growth of
cancerous cells
IV nutrient therapy
Disadvantage
Painful & Fearful
Infection Supervisor required to administer
Disadvantage
Irreversible Coagulation
CARRIER SYSTEM
Biochemically inert (non-
toxic)
Non-immunogen
ic
Physically and chemically
stable in vivo and in vitro conditions
Carrier systems convey drugs to specific receptors and ligands and physically modulate components.
