The choice of an appropriate container when packaging pharmaceutical dosage forms is very important. You must first understand which materials are compatible with your application. Glass containers are the most common form of packaging for pharmaceuticals. These are intended for direct contact with pharmaceutical products. Commonly used glass is either composed of Borosilicate Glass or Soda-Lime Glass. Per USP[i], there are three types of glass: Type I (Borosilicate), Type II (Soda-Lime with hydrolytic resistance) and Type III (Soda-Lime Silica).
Most packaging manufacturers hold a US-FDA Drug Master File (DMF) type III Packaging Material. This is very helpful when filing your final product with the FDA.
Another factor to keep in mind when selecting packaging containers for pharmaceuticals are handling considerations. Tubular vials withstand thermal shock better than molded glass containers[ii].
