Radiopharmaceuticals: When Logistics Becomes Part of the Treatment

A delay of just a few hours can compromise the use of certain medications.

Although this situation may seem unusual in most pharmaceutical operations, it is a reality for radiopharmaceuticals—medications used in diagnostic tests and treatments that rely on radioactive elements to fulfill their clinical function.

Unlike conventional drugs, many radiopharmaceuticals begin to lose their activity as soon as they are produced. In some cases, the time available for quality control, transport, storage, and administration to the patient can be measured in just a few hours.

What's more, With advances in nuclear medicine and the growth of precision therapies, these drugs are becoming increasingly important in the healthcare field. In this context, logistics is no longer just an operational step; it now plays a key role in ensuring that treatment takes place at the right time.

What are radiopharmaceuticals?

Nuclear medicine professionals use radiopharmaceuticals—which combine pharmacological substances with radioisotopes—to perform diagnostic procedures and treatments.

In practice, these medications help doctors diagnose diseases, monitor organ function, and treat certain types of cancer.

According to the International Atomic Energy Agency (IAEA), radiopharmaceuticals play an essential role in modern medicine, contributing to more accurate diagnoses and increasingly targeted therapies.

Currently, healthcare professionals use these medications primarily for:

• PET-CT scans;
• SPECT scans;
• Cardiovascular diagnosis;
• Neurological evaluation;
• Targeted cancer treatments.

The half-life that defines the entire operation

The main logistical challenge associated with radiopharmaceuticals relates to what is known as the radioactive half-life.

Half-life is the time it takes for half of a radioisotope's radioactivity to decay naturally.

Some of the most commonly used radioisotopes have extremely short half-lives:

• Fluorine-18 (18F): approximately 110 minutes;
• Gallium-68 (68Ga): approximately 68 minutes;
• Carbon-11 (11C): approximately 20 minutes.

In practice, this means that the time available between the production and use of the medication is limited. Consequently, the longer the delay, the less radioactive activity will be available for the procedure.

For this reason, each stage of the operation must be carefully planned.

When Every Hour Counts

While many medications can be stored for months or even years, many radiopharmaceuticals require extremely precise coordination between production and use.

That way, the process typically involves:

• Production of the radioisotope;
• Formulation of the radiopharmaceutical;
• Quality control;
• Regulatory approval;
• Specialized transportation;
• Receipt issued by the hospital or clinic;
• Administration to the patient.

In addition, in many cases, these steps must be completed within a few hours.

For this reason, logistics plays a critical role in ensuring that the medication remains effective until it is administered.

The Growth of Nuclear Medicine

In recent years, nuclear medicine has seen significant advances driven by the development of new therapies and diagnostic technologies.

A Society of Nuclear Medicine and Molecular Imaging (SNMMI) It highlights that the field is undergoing a period of rapid expansion, driven in particular by radioligand therapies used to treat various types of cancer.

Among the best-known examples are therapies such as Pluvicto®, used in certain cases of advanced prostate cancer, and Lutathera®, indicated for neuroendocrine tumors.

As a result, the growth of these applications is driving demand for highly specialized logistics operations capable of meeting strict requirements for timeliness, security, and traceability.

Why is logistics part of the treatment?

In many pharmaceutical operations, the primary goal of logistics is to ensure availability and efficiency.

In the field of radiopharmaceuticals, she takes on an even greater responsibility.

At the same time, the expansion of nuclear medicine requires increasingly coordinated operations among manufacturers, transporters, and healthcare institutions.

In other words, since radioactivity continuously decreases over time, coordination between manufacturing, transportation, and administration directly affects the use of the medication.

An unexpected delay can disrupt exam schedules, require rescheduling of clinical appointments, and reduce the time available for certain procedures.

Therefore, factors such as:

• Logistics planning;
• Route control;
• Real-time monitoring;
• Chain of custody;
• Risk management;
• Traceability;

They are no longer merely operational requirements but now contribute directly to the success of the operation.

Scientific precision requires logistical precision

Radiopharmaceuticals are one of the clearest examples of how science and logistics go hand in hand in the field of healthcare.

As nuclear medicine continues to evolve and new therapies enter the market, there is a growing need for operations capable of keeping pace with the speed and complexity of these treatments.

In a situation where every minute counts, ensuring that medication reaches the right place at the right time is an essential part of the treatment process.

Therefore, rather than simply moving products, specialized logistics helps bridge the gap between scientific innovation and patient care, enabling advances in modern medicine to be effectively applied in clinical practice.
