Track 37: 3D Printing in Pharmaceuticals

3D Printing in Pharmaceuticals

3D printing, also known as additive manufacturing, refers to the process of creating three-dimensional objects layer by layer from digital models. This technology, which has been widely used in industries ranging from aerospace to fashion, is now making significant strides in the pharmaceutical sector. In pharma, 3D printing is used to manufacture personalized medications, drug delivery systems, medical devices, and even complex biologics. The ability to create customized, patient-specific treatments is revolutionizing how drugs are developed, distributed, and consumed.

Key Applications of 3D Printing in Pharmaceuticals

1. Personalized Drug Dosage Forms

One of the most promising applications of 3D printing in pharmaceuticals is the personalization of drug dosing. Traditional pill manufacturing involves standard dosage forms, which may not be ideal for every patient. With 3D printing, manufacturers can create customized pills tailored to individual needs based on factors like age, weight, medical history, and specific conditions.

• Customized Dosing: 3D printing allows the creation of dosage forms with precise amounts of active pharmaceutical ingredients (APIs). For example, a patient who requires a specific dosage that is not commercially available can have a pill tailored to meet that exact need.
• Multi-drug Combinations: 3D printing can also be used to create polypills, which are single pills that contain multiple active ingredients. This can be particularly useful for patients who need complex treatments involving several drugs, such as those with chronic diseases like hypertension or diabetes.
• Pediatric and Geriatric Populations: For children or elderly patients who may have difficulty swallowing large tablets or capsules, 3D printing allows for the creation of pills in specific shapes and sizes that are easier to ingest.

Example: Aprecia Pharmaceuticals has developed the first FDA-approved 3D-printed drug, Spritam (levetiracetam), which is used for the treatment of epilepsy. The drug is printed in a porous form, allowing it to dissolve rapidly when taken, making it easier for patients with difficulty swallowing pills.

2. Drug Delivery Systems

3D printing allows for the creation of complex drug delivery systems that can release medications in a controlled or targeted manner. These systems can be designed to release drugs over extended periods or at specific sites in the body, improving the effectiveness of treatment and reducing side effects.

• Controlled Release: 3D printing enables the design of tablets or capsules with multiple layers or compartments, each releasing different doses of a drug at specific times. This can enhance the pharmacokinetics of a drug and improve patient compliance by reducing the number of doses required per day.
• Targeted Delivery: Using 3D-printed materials, pharmaceutical companies can develop devices that release drugs directly to targeted areas, such as specific tissues, organs, or cells. This is particularly valuable in treatments for diseases like cancer, where targeting the drug to the tumor site can minimize systemic side effects and maximize therapeutic efficacy.
