5 5 Drug degradation induced by uncontrolled moisture Meeting the challenge of stability requires an understanding of the mechanisms leading to a loss in performance of the pharmaceutical. CHEMICAL DEGRADATION LOSS OF POTENCY DEGRADATION PRODUCTS PHYSICAL DEGRADATION API FORM MODIFICATION DISSOLUTION ACCURACY OF DELIVERY MECANICAL PROPERTIES PHYSICAL APPEARANCE

6 6 The challenge of drug protection STABILITY USAGE

7 7 Controlled headspace has two primary dimensions An optimized packaging systems calls for combined expertise in Designing the barrier Limiting the ingress of moisture from the outer environment into the packaging s interior Designing the active protection Managing the moisture exchange occurring inside the microenvironment of the packaging

8 8 Time of protection is not an absolute value Drug protection time is not an absolute value set by packaging design attributes, but will result also from drug properties and conditions of use. Absorption Capacity (mg) Protection time (days) Moisture burden (mg/day)

9 9 Protective barrier Clariant Healthcare Packaging

10 10 Protective barrier Preserves the products contained in the packaging from the environment MVTR quantifies the barrier performance of a package against moisture transmission. Its is the combined result of : Design attributes Usage attributes

11 Design Attributes Usage Attributes 11 Conclusion (Protective barrier) Passive performance of the packaging is not an absolute value. Moisture transmission rate needs to be expressed in regard with the test conditions Absorption Capacity (mg) Ingress rate (mg/day) = Protection time (days) Passive barrier Size and shape Raw materials Seal quality Usage Climate zone Storage conditions

12 12 Active Moisture Control Clariant Healthcare Packaging

13 13 Active moisture control The role of desiccants is to maintain the atmosphere inside the container below the degradation threshold during the entire shelf-life Desiccant capacity is determined to Compensate for packaging permeability Adsorb the moisture initially introduced inside the packaging

14 14 Adsorbents Silica gel - amorphous silicon dioxide - water vapor adsorption Molecular Sieve - synthetic zeolite - water vapor and gas adsorption Bentonite - desiccant clay Adsorbents are Hygroscopic substances that physically bind water vapor from the air to fix it on the surface of a solid. They are used to maintain a dry atmosphere in containers. Activated Carbon 2-in-1 ADP - odor adsorption - desiccant + carbon - water vapor and odor adsorption - desiccant polymer - water vapor adsorption and barrier

15 15 Life cycle of a packaging with desiccant At packaging Moisture enters the headspace In-use by patient Moisture enters through repeated opening/closing cycles 1 4 After packaging Moisture transfers from drug products to the desiccant 2 3 During shelf storage Moisture ingresses by permeation

16 16 Thinking as a system System oriented mindset is required to Optimize costs of the complete solution Develop customized design for covering the specific drug requirements Reduce stability iterations and save development time Climatic conditions and profile of use Closure Drug product Desiccant Container

17 Design Attributes Usage Attributes 17 Full system active moisture control requires evaluation of all parameters The actual capacity which is relevant for an application can not be derived from a single data point disclosed by material specification: it has to be considered in regard with the maximum admissible exposure level of the product contained in the packaging. Desiccant Sorption isotherm Dosage Drug product Drug sorption isotherm Chemical stability Physical stability Absorption Capacity (mg) Ingress rate (mg/day) = Protection time (days)

18 18 Available Desiccant Configurations Clariant Healthcare Packaging

19 19 Desiccants within pharmaceutical containers Dropped-in Integrated Integrated Embedded

20 20 Drop-in desiccants Drop-in desiccants are the most standardized and are fully automatable Canisters & Capsules High speed automatic insertion ( cpm) Continuous run (hopper fed) Printed or labeled Packets Continu-Strip hole punch packets Compatible with all standard insertion equipment on the market

21 21 Integrated desiccant Desiccant component incorporated into the container or closure Tubes & Stoppers Printed tubes 6-color offset Innovative stopper closure - Desiccant - Tamper evident - Spiral or non-spiral - Hot stamping IDC Built-in desiccant Tamper evident Child resistant (option) Ergonomic Screw or snap cap Precision molding eliminates need for induction seal

22 22 Embedded ADP Advanced Desiccant Polymer Desiccant embedded directly into plastic, providing humidity protection in limitless configurations Dustless desiccant Conducive to multiple molding processes depending on application Ideal for diagnostic or pharmaceutical applications Secured cap ADP Insert Exterior HDPE vial

23 23 Latest developments : EQuilibrium sorbent Clariant Healthcare Packaging

24 24 Water activity Introducing a drug product with conventional sorbents inside a container, will change the initial state of the drug product. Typically some moisture from the dosage forms transfers to the desiccant. Standard desiccant dosage will typically maintain low humidity inside the packaging throughout the shelf storage period

25 25 Impact of relative humidity on hard or soft gel tablets At low humidity, capsules may lose moisture and become brittle. At high humidity, capsules may gain moisture and soften, swell or fuse together Hence, special care for handling and storage is required, and remaining packaging options are often limited.

26 26 EQ provides moisture regulation within packaging EQ solutions are designed to maintain a specific equilibrium relative humidity Specially engineered to perform simultaneously as an humectant or a desiccant, maintaining a the equilibrium relative humidity (erh) inside a product packaging within a predetermined range. EQ is available via canisters, packets and bags platforms: EQ-Pak and EQ-Can to address : Risks of excessive humidity: Instability, deliquescence; decomposition, microbial growth, Risks of excessive dryness: efflorescence of the coating or API; impairment of drug deposition (inhalation), brittleness (gel caps), electrostatic loading (powder bulks),
