Summary of the Video

“FILM PÉDAGOGIQUE PRESENTE A L’OCCASION DES 100 ANS DE SANOFI SISTERON”

This educational film explains the manufacturing processes of active pharmaceutical ingredients (APIs) at Sanofi, celebrating its 100 years of operation. It highlights the history, scientific principles, and industrial techniques involved in producing medicines that help cure or relieve patients. The video focuses on four main methods of producing active ingredients and the rigorous quality controls in place to ensure safety and efficacy.

Main Ideas and Concepts

1. Introduction to Active Ingredients in Medication

A pill contains an active substance with therapeutic effects.
Humans have historically sourced remedies from nature (plants like thyme, foxglove, valerian).
Modern medications may still use plant-derived substances but also rely on other production methods.

2. Four Main Manufacturing Processes of Active Ingredients at Sanofi

Plant Extraction (Aramon Site)

Raw materials: dried plant extracts arriving as granules.
Process steps:
- Granules are examined, ground, and soaked in solvents.
- Extraction produces a liquid containing active molecules.
- Liquid is mixed with solvents, concentrated, crystallized, filtered, purified, pressed, and dried.
- Resulting powder (~90% active ingredient) undergoes further chemical synthesis to become the final active ingredient.

Chemical Synthesis (Sisteron Site)

Raw materials: already transformed molecules.
Process:
- Molecules analyzed and mixed with solvents in large reactors.
- Temperature and pressure controlled to trigger chemical reactions.
- Synthetic molecules crystallized, cooled, spun dry, washed, and dried.
- Multiple synthesis steps may be needed.
- Final products undergo precise analytical testing.
Development:
- Research and development teams invent and scale up production processes in workshops before industrial manufacturing.

Fermentation (Saint-Aubin-lès-Elbeuf and Vertolaye Sites)

Based on yeast (a microorganism) discovered in antiquity.
Process:
- Yeast strains multiplied in progressively larger vessels (from tubes to large fermenters).
- Yeast cells produce the active ingredient during fermentation.
- Ultrafiltration separates cells from product.
- Product extracted, washed, concentrated, cooled, precipitated, filtered, dried, and packaged.
- Further purification at Vertolaye via chromatography (silica gel column) to remove impurities.
- Final product micronized to improve delivery efficiency in the body.

Cell Culture / Biotechnology (Vitry-sur-Seine Site)

Uses genetically modified animal cells to produce complex drugs like monoclonal antibodies.
Cells amplified in increasing container sizes, up to 10,000-liter bioreactors.
Cells genetically programmed to produce the antibody.
Extraction and purification:
- Cell separation and filtration to remove impurities.
- Three purification steps isolate the antibody.
- Stabilizing liquid added for long-term storage and safe administration.
- Product stored at -28°C.
Biotechnologies address unmet medical needs, especially in cancer treatment.

3. Quality Control and Safety Measures

Operators wear full-body disposable suits, masks, gloves, and hoods with filtered air to avoid contamination.
Strict sterile working conditions maintained.
Waste (gas/liquid) from production is purified before environmental release.
Personnel undergo rigorous training.
Factories inspected regularly by multiple international health authorities (French, European, American, Japanese).

4. Post-Production Processing

Active ingredients leave chemical plants and are processed into final pharmaceutical forms such as capsules, suppositories, creams, injectables, syrups, and powders.
Processes include coating, film coating, and addition of adjuvants.

5. Overall Message

Sanofi’s commitment to producing safe, high-quality medicines through advanced, controlled manufacturing processes.
Emphasis on innovation, precision, and patient safety.
