The demand for advanced dug delivery is rising, as subcutaneous injection is the most desirable route of administration in several therapeutic areas including hemophilia, auto-immune disorder, cancer intravenous immunoglobulin, and multiple sclerosis. Furthermore, the cost of administration of a single dose of specialty drug via IV infusion in clinics or hospitals costs about $1,000 to $10,000. The cost for the administration of the same dose is decreased by 30% to 70% in home care settings. Attributed to these factors, the demand for advanced drug delivery devices, such as wearable injectors in increasing, as patients can take the infusion themselves with minimal or no training.

A wearable injector is used for delivering large volume of drugs over an extended period of time. The device delivers large subcutaneous drug doses to patients even when the patient is ambulatory and is able to carry out normal daily activities during the day. The wearable injectors market is projected to grow at a considerable pace in the near future. Different types of wearable injectors are bolus injector, body-worn patch injector, and off-body worn belt injector. Among these, body-worn patch injector was the most in demand in the past. However, bolus injectors are predicted to be the most in demand in the coming years.

The various applications of wearable injectors are blood disorder, cancer, cardiovascular disease, autoimmune disease, and infectious disease. Out of these, the largest demand for wearable injectors was created for cancer in the past and the situation is expected to remain the same in the coming years as well. There are different biologic drugs which need to be administered frequency for the treatment of cancer, which results in increased healthcare maintenance cost. In addition to this, the patient has to visit hospitals or specialized clinics in order to get a dose, which cause the patient discomfort. However, with the introduction of wearable injectors, the patients can self-administer the drugs.

Among all the regions, North America accounted for the major share of the wearable injectors market in the past and is expected to dominate the market in the near future. This is because of the surging prevalence of chronic and lifestyle- associated diseases and rising requirement for self-injection system. The Asia-Pacific region is predicted to witness the fastest growth in demand for wearable injectors in the coming years. The reason for this is the surging geriatric population in the region. As per the UN publication, the number of people aged 80 years or above was 9 million in Japan in 2013 and is predicted to reach 17 million by 2050.

Since elderly people are more susceptible to chronic diseases, such as cardiovascular diseases, cancer, diabetes, and neurological disorders, they need extensive care, which is resulting in the rising requirement for wearable injectors. According to the United Nations Department of Economic and Social Affairs’ report on the global aging population, the number of people aged 60 years or above is expected to grow by 56.0% across the world and is predicted to reach 1.4 billion by 2030.
