Auto injector is a medical device designed to deliver a single dose of a particular drug, usually lifesaving. Most auto injectors are spring-loaded syringes. By design, auto injectors are easy to use and are intended for self-administration by patients, or administration by untrained personnel. The site of injection depends on the drug loaded, but it typically is administered into the thigh or the buttocks. Injectors were initially designed to overcome the hesitation associated with self-administration of the needle-based drug delivery device. Auto-injectors offer a whole range of benefits to both end users and healthcare professionals. They make self-administration easier, which improves patients’ safety and reduces their anxiety. In turn, these factors can also help to support patient compliance. Contract Packaging Organizations (CPOs) can specifically design biotechnology packaging to meet particular programme objectives once you have a defined parental container and clearly identified end users. It’s all about ensuring the safe delivery of the product in optimum condition, at the most competitive price. Pharma Packaging service providers usually offer Semi or fully automatic assembly lines with dedicated lines for specific devices Inline labelling, laser coding, code verification and label alignment. Contract Packaging Organizations (CPO) experts can offer packaging services for Auto-injectors and pens with various advantages: Semi or fully automatic assembly lines; Inline and offline labelling, laser coding, code verification and label alignment; Automatic loading into pre-formed trays; Up to three leaflets per product pack; Cartoning with tamper-evident labelling; Customised packaging solutions; 2D matrix printing; Serialisation of products at 4 levels: carton, kit, shipper and pallet. Auto injectors typically contain glass syringes, making them fragile, causing contamination. In a bid to boost patient compliance, more and more pharmaceutical manufacturers are investing in patient-centric training tools including specially adapted auto-injector/pen packaging designs. Studies have shown that the more senses a packaging design triggers, the stronger its message is encoded in the brain. Hence, manufacturers are increasingly wrapping prefilled auto-injectors in packaging that not only consists of visuals but also includes auditory scripts. Some manufacturers have even adopted an interactive approach by including visual or auditory sensors which let the patient know when they’ve made a mistake. Furthermore, the sensors prevent the patient from moving forward in the self-administration process until they’ve gotten the previous step right.
