Drug delivery is becoming a whole interdisciplinary and
an independent field of research and is gaining the attention of
pharmaceutical makers, medical doctors, and industry. A
targeted and safe drug delivery could improve the performance
of some classical medicines already on the market and,
moreover, will have implications for the development and
the success of new therapeutic strategies, such as peptide and
protein delivery, glycoprotein administration, gene therapy and
RNA interference.
Drug delivery system for biotech product considering stability aspects and monitoring methods of improving stability.
1. Presentation On:
Designing of Drug Delivery System
for Biotechnology Products
Considering Stability Aspects and
Monitoring Methods of Improving
Stability.
3. Contents:
• What is biotechnology and biotechnology products?
• Routes of drug delivery.
• Designing of drug delivery system for biotechnology products.
• Stability parameters.
• Methods of improving stability.
4. Any technological application
uses biological system to
produces modified product.
Example:
•Recombinant DNA
• Stem cell therapy
•Cloning.
Biotechnology:
5. Product which are manufactured by
Modified Genetic Materials of living
cell at molecular level.
Example:
• Antibiotics
• Vaccines
• Genetically Modified
Organism(GMO)
• Insulin
Biotechnology

7. Designing of Drug
Delivery System for
Biotechnology Products:
Gene Therapy.
Monoclonal Antibodies.
Protein and Peptide Technology.
Encapsulation Methods.2.

5.
Recombinant DNA Technology.
1.
8. A technique to deliver DNA
or RNA molecules to cells/
tissues for the treatment of
genetic disease.
Gene Therapy:
Identification
of affected
gene.
Cloning
identical
healthy
gene.
Loading the
vector with
therapeutic
gene.
Vector
reaches
the target
cell.
Delivering the
therapeutic gene
into the nucleus of
the target cell
Genetic material
integrated into
DNA & performs.
11. Non-viral vectors are
molecules of circular
DNA.
Non-Viral Methods:
Physical
methods:
Laser irradiation,
electroporation,
magnetoporation,
ultrasound.
Mechanical
method:
Necked DNA
injection,
microinjection, gene
gun.
Chemical &
synthetic
method:
Liposomes,
polymers, inorganic
nanoparticles.
12. Microencapsulati
on:
Microencapsulation
products do not interfere
with other ingredients.
Microencapsulated
ingredients can be added at
any time in the processing
and remain unaltered.
Sensory properties
remain unaltered.
Increased self-life
and consumers are
able to taste the
added capsule.
21. Improving Stability:
PEGylation
Improving the safety and
efficiency of many
therapeutic
macromolecules such as
Protein and Peptides
Example:
Pegademase Bovine
Pegaspapargase
Pigvisomart etc.
22. Improving Stability:
• Developed to produce
enzymes with improved
functional properties
including stability.
Stochastic
laboratory
techniques
• Sequence and structure
analysis.
• Example: Design Protein,
Unveiling Protein Folding.
Empirical
rational design
23. Conclusion:
By overcoming the current
obstacles, including government
regulations, financial support, and
large-scale production and
manufacturing will lead us to a day
where all biotechnology products
are delivered in a targeted and safer
manner.
