项目摘要
PROJECT ABSTRACT
Plastic offers several key advantages over Type 1 borosilicate glass as a material for parenteral
pharmaceutical containers (e.g. vials and prefilled syringes). Plastic is less prone to breakage, and can be
molded into more complex shapes with tighter dimensional tolerances than glass. Additionally, plastic is not
susceptible to glass delamination — a major problem in the industry where a drug product chemically attacks its
glass container, resulting in glass fragments flaking off into the drug.
The primary disadvantage of plastic parenteral containers is their relatively high oxygen permeability,
which can reduce the shelf life of oxygen-‐‑sensitive drug products. This shortcoming can be eliminated by
applying a barrier coating to the container that drastically lowers the container'ʹs oxygen permeability. The
viable candidate materials from which to make this oxygen barrier coating have similar chemistries to glass,
and thus have similar susceptibility to chemical attack. Therefore, the oxygen barrier coating requires the
protection of an additional passivating layer.
TriboFilm Research, Inc. (TriboFilm) is developing a bi-‐‑layer oxygen barrier + passivation coating
system for use on plastic parenteral containers, called TriboShield™. The TriboShield™ coating system is
expected to outperform all existing competing products for two reasons. First, the Atomic Layer Deposition
(ALD) technique that TriboFilm uses to create the oxygen barrier layer makes higher quality barrier films than
can be achieved using other barrier coating techniques. Higher quality films will have significantly lower
oxygen permeability because they will have fewer cracks and 'ʹpinholes'ʹ in the film for oxygen to permeate
through. Second, TriboFilm has developed a proven passivating coating for glass prefilled syringes which will
be modified for use on barrier coated plastic containers. The passivating coating also acts as a high-‐‑
performance lubricant for syringes.
TriboFilm'ʹs goal for Phase I is to create an advanced coating system for plastic parenteral containers
that provides outstanding oxygen barrier properties to extend the shelf life of oxygen-‐‑sensitive products, and
presents a surface to the drug product that, (a) is chemically inert and resistant to attack from the container'ʹs
contents, (b) will not migrate into the drug product in the form of leachables, extractables, or particles, and (c)
is an effective lubricant, allowing a prefilled syringe incorporating the system to be used without any
additional lubrication. When successful, the TriboShield™ technology could be applied to vials, prefilled
syringes, or any other plastic container, offering seamless transition for a pharmaceutical company from one
container format to another during the life cycle of a drug. This could save a company millions of dollars in
reformulation costs and time to market while transitioning, e.g., from a vial to a prefilled syringe.
项目摘要
与1型硼硅酸盐玻璃相比,塑料作为胃肠外给药材料具有几个关键优势
药物容器(例如小瓶和预充式注射器)。 塑料不太容易破碎,
模塑成比玻璃更复杂的形状,具有更严格的尺寸公差。此外,
易受玻璃脱层的影响-这是药物产品化学侵蚀其
玻璃容器,导致玻璃碎片剥落到药物中。
塑料肠胃外容器的主要缺点是它们相对高的透氧性,
这会缩短对氧气敏感的药物产品的保质期。 这个缺点可以通过以下方式消除:
将阻隔涂层施加到容器上,该阻隔涂层显著降低容器的氧气渗透性。 的
制造这种氧气阻隔涂层的可行的候选材料具有与玻璃相似的化学性质,
因此对化学侵蚀具有相似的敏感性。 因此,氧气阻隔涂层需要
保护额外的钝化层。
TriboFilm Research,Inc.(TriboFilm)正在开发一种双层阻氧+钝化涂层
TriboShield™用于塑料注射容器。 TriboShield™涂层系统
预计将优于所有现有的竞争产品,原因有二。 第一,原子层沉积
(ALD)TriboFilm用来制造阻氧层的技术制造的阻氧膜质量比
可以使用其它阻挡涂层技术来实现。 更高质量的电影将有显着降低
氧气渗透性,因为它们将有较少的裂缝和“针孔”,在薄膜中的氧气渗透
第二,TriboFilm开发了一种经过验证的玻璃预充式注射器钝化涂层,
可以被修改以用于阻隔涂层的塑料容器。 钝化涂层还可作为高抗腐蚀涂层,
注射器的高性能润滑剂。
TriboFilm公司第一阶段的目标是为塑料注射容器创建一个先进的涂层系统
提供出色的氧气阻隔性能,以延长氧气敏感产品的保质期,
给药物产品提供一个表面,该表面(a)是化学惰性的,并且抵抗来自容器内壁的侵蚀,
内容物,(B)不会以可溶解物、可浸提物或颗粒的形式迁移至制剂中,以及(c)
是一种有效的润滑剂,允许使用包含该系统的预充式注射器,
额外润滑。 成功后,TriboShield™技术可应用于小瓶、预灌装
注射器或任何其他塑料容器,为制药公司提供从一个
在药物的生命周期中,将容器格式转换为另一种容器格式。这可以为公司节省数百万美元,
在过渡过程中,例如, 从小瓶到预充式注射器。
