Drug Delivery Systems - Subcutaneous, solid implants are an emerging drug delivery system with special manufacturing needs when going from powder to ready-for-packaging product. In order to deliver the active pharmaceutical ingredient (API) safely and with a constant dissolution rate, a very homogeneous product with extremely tight tolerances in geometry is required. And when automating an implant manufacturing line, it becomes even more critical to assure consistent API/excipient compounding and to maintain precise quality specifications. Let us show you how.
Advantages of drug delivery systems
Subcutaneous implants or vaginal rings offer several advantages over solid oral dosage forms:
- The active pharmaceutical ingredient (API) can be released where it is needed most, reducing the required dose and helping reduce the drug's side effects
- The drug doesn't need to be administered as often, increasing the acceptance of new delivery systems
- Biodegradable materials can often be used in the manufacture of the delivery system, eliminating the need to remove implants
Pharma mini Implant Line
The Pharma mini Implant Line offers the opportunity to develop and manufacture implants in a fully automated and continuous process. This line uses a programmable logic controller (PLC) from material feed through to the final quality control of the implant size, including documentation such as batch report and audit trail.
A container with a containment valve for pre-blended material is connected to the gravimetric feeding system, enabling operator-safe handling and high accuracy in the feed rate. The Pharma mini HME Micro-Compounder produces a strand with a small diameter tolerance (¡¾0.005% to 0.05% depending on mechanical parameters of the compounds used). A laser sensor delivers data to control the strand diameter very precisely by adjusting the conveyor speed. Based on this data, the strand is cut to meet the length specifications of the implant. An automated sorting device assures that any out-of-specifications (OOS) implants are rejected and collected away from the in-spec implants.
CaliCut Post-extrusion System for implant production
As an accessory to our Pharma mini HME Micro-Compounder, we offer Thermo Scientific CaliCut Post-extrusion System to precisely calibrate polymer strands and cut them into well-defined implant devices.
As an accessory to the Pharma mini Extruder, this cutting system can be operated independently from the extruder control. It complements the extruder if fully automated production is not necessary or if the implant project is still in an R&D phase. The CaliCut System can produce 600 cuts/hour with variable lengths (1~200 mm) and diameters (0.2~6 mm). Its small footprint makes it an ideal addition to the Pharma mini HME Micro-Compounder.

Hot Melt Extrusion
Overcome drug formulation challenges
- Pharmaceutical manufacturers are using conical and twin-screw extruders to mix drug molecules with bioactive polymers in situations where drug ingredients are poorly soluble or unstable during processing. Extruders are also useful in preparing enteric dosages, sustained release dosages, in taste-masking, and to create forms such as films.
Why hot melt extrusion?
![](images/why1.jpg)
Hot melt extrusion (HME) is the processing of polymeric materials above their glass transition temperature (Tg) in order to effect molecular level mixing of thermoplastic binders and/or polymers and active compounds. Used in several industries, HME is a combination of melting and mechanical energy to improve continuous processing for reproducible analysis of materials, dust reduction and online monitoring.
In pharmaceutical manufacturing, HME is used to disperse APIs in a matrix at the molecular level, thus forming solid solutions. This enables drug delivery systems for poorly soluble drugs or specialized drug forms such as films for transdermal patches.
Watch our webinar series - Improving Solubility with Hot Melt Extrusion
Polymers
![](images/why2.jpg)
The choice of an adequate polymer as a matrix to form stable solid solutions is crucial in HME. Polymers with a high solubilization capacity are particularly suitable because they can dissolve large quantities of drugs. Polymers for hot melt extrusion experiments are based on different monomers and chemical structures, such as homopolymers, copolymers, amphiphilic copolymers as well as solubilizers and plasticizers. Consideration for each material must take into account the polymer's solubility in a solvent, which can vary from high lipophilicity to high hydrophilicity. A suitable solvent need to be selected for the preparation of solid solutions by spray drying, where polymer and drug must be dissolved in a volatile solvent.
Polymers for hot-melt extrusion must exhibit thermoplastic characteristics and must be thermally stable at the proper extrusion temperature. In developing an HME drug system, the glass transition and melting temperatures are critical factors. The extrudability of a polymer is mainly determined by Tg or Tm and melt viscosity. Most polymers demonstrate thixotropic behavior where the viscosity reduces as a function of increasing shear stress.
Active pharmaceutical ingredients
![](images/why3.jpg)
Present drug discovery methodology produces candidate drugs of increasing molecular size and lipophilicity, which results in poor solubility and permeability. Less than 10% of new drug candidates demonstrate both high solubility and permeability, and 30~40% of the drugs that appear on the World Health Organization Essential Drug List were reported to be poorly water-soluble or lipophilic. HME disperses the drug in the matrix at a molecular level by forming a solid solution.
HME is available for a number of applications, including amorphous solid dispersion, controlled release systems, polymorph generation, novel cocrystallisation (solvent-free continuous cocrystallisation), porous polymeric systems and Process Analytical Technology (PAT).
Watch webinar - Employing Hot Melt Extrusion As a Cost Effective Method of Increasing Solubility Of Water Insoluble APIs
Processing parameters
![](images/why4.jpg)
In the hot melt extrusion process, the API and the excipients are fed into the extruder. All components are sheared, heated, plastified, mixed and dispersed, and finally shaped by pressing them through a die opening. Developing a HME manufacturing project requires control of several processing parameters that affect residence time distribution, and specific mechanical energy consumption (SMEC) must be considered such as temperature of the melt at the extruder die, pressure at the die, and torque.

Drug Formulation and Manufacturing
Solutions for scale-up and continuous processing
- Addressing challenges in pharmaceuticals where API solubility and processing stability, taste-masking, enterics, and specialized dosage forms are critical projects, Thermo Scientific extruders and related analytical instrumentation provide the shortest path from feasibility studies to production in drug formulation and manufacturing.
Compounding and extrusion technologies have been used in manufacturing for centuries and have become a valuable tool in creating novel drug formulations, and in the transition from inefficient batch processing to continuous manufacturing.
Featured drug formulation and manufacturing technologies
Hot Melt Extrusion
![](images/drug2.jpg)
Melt extrusion has been used in the plastics and polymers industry for decades. Advances in formulation enable poorly soluble drug molecules to be incorporated into solid dispersions using a polymeric carrier. Hot melt extrusion is an alternative to wet agglomeration, a good carrier for sustained release forms and taste-masked dosages. Extrusion processes can also create films for oral strips or dermal patches in a solvent-free process.
Drug Delivery Systems
![](images/drug3.jpg)
Hot melt extrusion (HME) is a key technology that can produce alternative drug delivery systems such as subcutaneous, solid implants for controlled-release treatment in ophthamology and cancer (e.g., hormone) as well as extrusion of biocompatible or biodegradable polymer/drug formulations.
HME can be configured to create a fully-automated implant production line with small tolerances in diameter and length. This continuous manufacturing process is an ideal solution, offering high-precision control of implant dimensions, a small footprint for full containment and simple cleaning for aseptic requirements of FDA approved materials.
Continuous Granulation
![](images/drug4.jpg)
According to the US FDA, the continuous manufacturing process reduces human errors caused by starts and stops during the batch process. Continuous granulation is also safer and more reliable. In a continuous process, ingredients are fed and mixtures sent to downstream production. Extruders have been used in wet granulation processes for many years; twin-screw extruders are now playing a central role in pharmaceutical manufacturing.
Analytical Instrumentation
![](images/drug5.jpg)
Rheometry and spectroscopy play important roles in developing and implementing extruder-centered drug formulations. The use of near infrared (NIR) spectroscopy for the analysis of active ingredients in pharmaceutical formulations is well known. The technique is nondestructive, has excellent signal-to-noise ratios and can use fiber optics to take sampling to the process. NIR spectroscopy is an ideal choice to monitor the output of a hot melt extruder. Complementary to NIR in bulk and in-line sampling, Raman spectroscopy adds microscopic imaging to analyze tablet homogeneity and the analysis of co-extrusions.
ODFs made easy with HME
![](images/drug6.jpg)
Orally disintegrating films (ODFs) allow safe, easy and exact dosage of active pharmaceutical ingredients (APIs). They also improve bioavailability of the API and help avoid the first pass effect. Hot-melt extrusion (HME) works well for manufacturing ODFs; it¡¯s well-established, provides reproducible results, and doesn¡¯t require solvents. Produce high-quality ODFs at lab- or production-scale.
Hints to optimize pharma processes via continuous granulation
![](images/drug7.jpg)
The switch from batch processing to continuous manufacturing of pharmaceuticals can really pay off with efficiencies and other savings. But how to set up a successful new continuous process - that's a challenge for everyone. We teamed up with Innopharma Technology to help.
Unique Advantages of Process Analytical Technology in Twin-Screw Granulation describes an experiment combining Thermo Scientific Twin-Screw Granulation (TSG) technology and Innopharma Process Analytical Technology (PAT). Read the results to learn which extruder parameters to adjust for the most impact on the continuous granulation process.

Scale-Up and Pilot Projects for Hot Melt Extrusion
Identify the right drug candidates
- Thermo Scientific twin-screw extruders are built with similar geometries. This enables experimentation and feasibility projects with a lab-scale (11 mm screw) extruder that minimizes the use of expensive APIs and enables easy clean-up between experiments.
Micro-compounder finds drug candidates
![](images/HMEMicroCompounder.jpg)
Finding the right API/excipients formulation and testing if this formulation is the right candidate for hot melt extrusion can be difficult. A micro twin-screw compounder requires as little as 3 grams of total material to identify the right drug candidates for hot melt extrusion. The compounder with conical co- or counter-rotating screws is designed to minimize waste and reduce downtime necessary for cleaning.
Benchtop extruder for research and small-scale production
![](images/pharma11.jpg)
With a minimum throughput of 20 g/h, a benchtop extruder is ideal for Phase 1 research applications, especially when developing and testing recipes with expensive API and associated compounds. As a GMP-compliant unit, the Thermo Scientific Pharma 11 is also suitable for clinical trials and small-scale production for throughputs up to 2.5 kg/h. The screw and barrel designs are geometrically scalable across the whole Thermo Scientific portfolio of extruders from lab and pilot through to production scale.
Formulation development platform
![](images/pharma16.jpg)
Designed to fit between the development lab and production line, a modular 16 mm twin screw extruder is capable of managing several drug formulation projects, including controlled release formulations, solubility enhancement, co-extrusion and implants, abuse deterrent formulations, and wet and melt granulation projects. A modular design enables formulation scientists to switch from hot melt extrusion and continuous granulation projects without engineering the extruder system.
Twin-screw granulation
![](images/Pharma24.jpg)
Reduce scale-up risks by running production on same equipment as development. A 24 mm twin-screw granulator will match the performance of 300 to 600 litre batch processors. Reduce in-process inventory to minimize risks to expensive ingredients and from ATEX hazards. Maximum volume of ingredients in the process is approximately 100 ml for 16 mm and 360 ml for 24 mm twin screw granulators.
Production-scale HME
![](images/tse24.jpg)
For consistent, controllable processing of hot melt drug formulations that are suitable for PAT, the 24mm twin screw extruder promises reduced product changeover time, minimized scale-up risk and easy cleaning.
This platform includes a number of integrated ancillary equipment for both project development and small-scale production including pre-mixers, feeders, chill rolls, air-cooled conveyors, pelletizers, and cast sheet or blown film lines.

Continuous Granulation
- Continuous granulation offers many opportunities to overcome the challenges of traditional batch production of tablets and capsules. It¡¯s efficient, inherently scalable and has advanced to a point of true reliability and flexibility. It can also be implemented all at once, or a little at a time. Consider the many ways below that twin-screw granulation can help you boost your oral drug formulation processes.
Continuous granulation ~ the future of oral drug manufacturing
Most oral drugs are available as tablets and capsules because it¡¯s easy to store and consume medicine in this form. Traditionally pharmaceutical manufacturers have created such oral dosage forms in batches. Now, many are considering a continuous manufacturing process. Why? How?
Why continuous granulation?

Small, medium and large batches of pharmaceuticals are prone to variations and expensive delays:
- Manual steps invite human error
- Transportation from one step to the next may cause material segregation
- Time-consuming disassemby and cleaning delay production
- Production scale-up requires bigger, more expensive equipment
Continuous manufacturing reduces/eliminates the issues above and makes subsequent tableting easier. With online monitoring, continuous manufacturing also enables drugs to be released as soon as they¡¯re manufactured ~ there¡¯s no waiting on analytical results before products can ship.
Today, continuous manufacturing is no longer an ¡°untested¡± process. Companies have gained experience and proven that it can be successfully implemented with a significant positive impact.
HME can be configured to create a fully-automated implant production line with small tolerances in diameter and length. This continuous manufacturing process is an ideal solution, offering high-precision control of implant dimensions, a small footprint for full containment and simple cleaning for aseptic requirements of FDA approved materials.
Set up continuous manufacturing so it really works!

Establishing a successful continuous twin-screw granulation (TSG) process can be tricky. Download this free whitepaper with expert advice for process design, development and scale-up for pharmaceuticals. The paper even includes information about how the parameters of twin-screw extruders can impact scale-up of a continuous process.
Batch Processing ~ it¡¯s OK to let go
It can seem daunting move away from batch processing which has served pharmaceutical manufacturers well for so many years. Many questions arise when looking at a new process:
- Will I lose flexibility for producing multiple products?
- How will I characterize the homogeneity of my mix?
Flexibility. There is great flexibility in continuous manufacturing. Switching production from one drug product to another is possible with quick, easy replacement of product contact parts to eliminate the risk of cross-contamination. And modularity allows the granulator to be easily set up for a different product¡¯s required process steps.
Characterizing homogeneity: Online analytical technologies (e.g., near-infrared or NIR spectroscopy) allow manufacturers to characterize homogeneity and other material properties at any time in the process. So the ability to characterize properties is maintained in continuous manufacturing via online analyzers.
How to implement continuous granulation?
Quantum leap vs Slow migration¡¦
The pharmaceutical manufacturing process can be continuously operated from mixing of initial powders to packaging of final tablets. This can be done with a twin screw extruder and subsequent drying in a fluidized bed system.
So the starting point can be small a stand-alone twin-screw granulator. If more granules are needed, simply run the instrument continuously for a longer period of time.
Modules can be added along the way, expanding the parts of the process that operate continuously:
- Dosing systems
- Dryers
- Tablet presses
- Etc.
A full continuous system can be grown module by module, or be put into place all at once with an entire processing line installation. Such installations often take place by scale-out or scale-up.
Scale-out: creating other small copycat systems in different locations or simply run the process on one instrument scale for a longer time period
Scale-up: transferring the process to high volume, high speed production systems
Thermo Scientific pharmaceutical twin-screw extruders are designed to bring you the benefits of continuous manufacturing whatever your pace may be.
We offer 11 mm, 16 mm and 24 mm pharmaceutical extruders that can stand alone or be partially or fully integrated into your manufacturing process. Systems are available for dual twin-screw granulation (TSG) or hot melt extrusion (HME) processes, or for dedicated TSG. Modules expand their use throughout the process from raw materials to tableting.
