3. 1. Introduction
Definition – a common or standard method, equipment,
procedure or work practice that may be applied across multiple
products under development or manufacture
It is valuable tool to improve efficiency and quality in drug
product development
Platform enables a continuous improvement by adding data for
every new molecule developed by this approach, increasing the
strength of the platform
3
4. 2. Importance of platform technology
It helps companies to improve customer experience
Improve the process for all stakeholders

5. 3. Examples of platform technology
1. Nanotechnology
Employing nanosize particles to deliver drugs to specific type of
cells e.g. cancer cells
Particles are engineered so that they are attracted to diseased
cells, which allow direct treatment of those cells
2. Microsphere technology
To develop differentiated formulations for targeted delivery
Aim – site specific action to eliminate repeated dosing and to
decrease side effect
3. Liposomal technology
Selectively target drugs for optimizing pharmacokinetic
parameters, pharmacological effect and reduce toxicity e.g.
Amphotericin B 5
6. Examples of platform technology continue…..
4. Hot melt extrusion technology
Used to produce molecular dispersions with considerable
advantages over solvent based processes e.g. spray drying
and co-precipitations
Used to provide SR (sustained release), modified and targeted
drug delivery
5. SR formulations technology
Ex. Osmotic controlled release oral delivery system (OROS)
formulated in tablet formulations
6. Multiple unit pellet system technology
Used to develop SR tablets
Tablets are made of multiple particulates that disintegrate into
individual pellets and provide sustained drug release 6
7. Examples of platform technology continue…..
7. Orally disintegrating (OD) formulations technology
Used to develop OD tablets that disintegrate rapidly when
placed upon the tongue and ensure faster onset of action
Patient convenience and compliance
8. Inhalations technology
Advantages in therapy of diseases of the respiratory tract
Faster action as compared to orally administered product
Ex. Metered dose inhalers, dry powder inhalers (unit dose –
rotahaler, revolizer; multidose – multii haler), autohaler (steroid
and long acting agonist), nasal sprays
9. Effervescent technology
Formulating effervescent tablets to provide quick relief along
with taste masking effects

8. Examples of platform technology continue…..
10. Sprinkles
Oral granule formulation specially designed for paediatric
patients
They can be sprinkled over a child’s food which makes the drug
palatable e.g. Anti- HIV therapy
11. Stem cell based products
Large scale production of adult mesenchymal cells from bone
marrow for therapeutic applications
12. Magnetic targeted carriers (MTCs)
They are microparticles (0.5 mm to 5 mm) composed of metallic
iron (75%) and activated carbon (25%)

GI tract
Celsion – Tumor targeting technology for heat sensitive
liposome
Sirenas - Speeding discovery and development of marine
inspired therapeutics
Phenotypic drug screening platform
Structure based and fragment based drug design technology
platform
Computation and informatics technology platform

11. 5. Pathway for development of platform
technology
A. Selection of candidate drug
1. Solubility/Dose
2. Stability
3. Lipophilicity/ permeability
4. Elimination half life (t1/2)
5. Therapeutic window
6. First pass metabolism
7. PK/PD realtionship
11
12. Pathway for development of platform technology continue……
B. Selection of polymers
1. Material used for matrix systems - hydrophilic polymers ;
crosslinked homoplymers and copolymers of acrylic acid,
insoluble polymers
2. Material used for reservoir systems
3. Polymer used for osmotic pump system - e.g. Cellulose
acetate
12
13. Pathway for development of platform technology continue……
C. Design and development of platform technology
Factors influencing the selection of CR technology
1. Match between technology attributes and physicochemical and
biopharmaceutical properties of drug candidate
2. Ease of adapting to a paediatric formulation
3. Manufacturing factors, including prior experience with the
technology
4. Inhouse processing expertise
5. Availability of commercial scale equipment and robustness of
performance on scale up
13
14. Pathway for development of platform technology continue……
D. Development process
1. Tabletting process
2. Spheronization/ pelletization process
3. Coating technologies
