Patient-Centricity in Drug Delivery Devices

February 16, 2016

OLYMPUS DIGITAL CAMERAAs medication self-administration becomes favored over hospital healthcare, drug delivery devices need to be provided to the patient with greater ease and efficacy. The ever-growing population has seen an increase in lifespans of those with chronic diseases, raising the demand for mobile treatment options catered to diverse patient groups.

In the earliest stage of drug development, the focus is on physiological and chemical aspects of the drug administration. The drug’s efficacy and safety requires as much consideration as its ability to improve the patient’s lifestyle and condition. Following the best method of administration is the challenge of addressing patient diversity. Because each patient differs in strength, size, dexterity, education, lifestyle, gender, culture, etc., his or her ability in utilizing the drug delivery device in their medical treatment must be considered.

The Need for Patient-Centric Approach in the Development of Drug Delivery Devices

According to Pharmaceutical Online, reports have indicated that patient non-adherence, instances when the patient does not maintain the recommended prescribed medicinal dosage, accounts for billions of lost revenue – $290 billion lost in the U.S. and almost double in the rest of the world. 4 billion prescriptions are assigned in the U.S. alone each year, with over half of them becoming void due to incorrect, or even lack of, administration. But in certain cases, rather than the failure of the patient to stick to their upkeep, the method of drug delivery itself is at fault.

With cases of Chronic Obstructive Pulmonary Disease (COPD), the ailment remains incurable, but treatment has proven to slow the disease progression while simultaneously providing a better quality of life. One of the treatments is applied through an inhaler device, which has many patient non-adherence issues. Occasionally, while the dosing schedule may be followed, the patient still may be using the inhaler improperly. A study showed that 89% of 316 patients using an inhaler made a mistake in their inhalation process, contributing to overall non-adherence. In instances such as this, the applicator is at fault, with the design not being patient-friendly in its application.

Two inhalers, the Diskus® inhaler by Advair and the Handihaler® by Spiriva were recently compared, with more patients preferring the Diskus due to the simpler usability in design. The hard evidence for such cases are bringing about positive changes in drug delivery device designs that focus on the results of human-centricity and patient-preference research.

How the Patient-Centric Approach Should Influence Patient Recruitment

The emphasis on patient-centric drug device application has been held in higher regard more so now than in the past. Clinical trials are unarguably of great value in advancements in biotechnological and pharmaceutical fields, but without patients such advancements would not be possible. Continuing with the targeted patient-centric approach, your clinical trial should focus on the needs of the patient in your recruitment process, a feature that we provide.
