World-Today-News.com | March 24, 2025 – Cambridge, MA – Engineers at MIT have pioneered a groundbreaking drug delivery system that promises to transform how medications, including contraceptives, are administered.The innovative approach involves injecting drugs as a suspension of tiny crystals that self-assemble under the skin into a long-lasting “depot,” possibly eliminating the need for frequent injections for months or even years.
Painless and Prolonged Drug Release
The new method offers the potential for delivering higher doses of drugs with significantly less pain. Because the drugs are administered as a suspension, they can be injected through a much smaller needle, improving patient comfort. this is particularly beneficial for treatments requiring extended durations, such as long-acting contraceptives or medications for chronic conditions.
Giovanni Traverso, an associate professor of mechanical engineering at MIT and a gastroenterologist at Brigham and Women’s Hospital (BWH), emphasized the system’s capabilities: “We showed that we can have very controlled, sustained delivery, likely for multiple months and even years through a small needle.”
Addressing the Need for Improved Contraceptive Options
The project initially stemmed from an effort funded by the Gates Foundation to broaden contraceptive options, especially in developing countries. though, the implications for women’s health in the U.S. are equally significant. Unintended pregnancies remain a persistent issue, and long-acting reversible contraceptives (LARCs) like IUDs and implants, while effective, require a visit to a healthcare provider for insertion and removal. This new injectable crystal technology could offer a more accessible and convenient alternative.
Dr. alice Reed, a leading researcher on the project, explained the potential impact on contraceptive access: “The goal is to offer a wider range of contraceptive options that are easier to administer and suitable for varying resource settings. The ability to provide women with long-acting, self-administrable injectables could greatly widen access, giving women access to different formats for contraception, with a range of different durations of action.”
This technology could be particularly beneficial for women in rural areas or those with limited access to healthcare facilities, offering a discreet and effective method of contraception that doesn’t require frequent clinic visits.
Overcoming Limitations of existing Injectable Suspensions
Current injectable drug suspensions often face challenges related to rapid drug release and the need for frequent injections. The MIT team’s approach overcomes these limitations by creating a stable, long-lasting depot under the skin. This depot slowly releases the drug over an extended period, providing consistent drug levels in the body and reducing the need for repeated injections.
This controlled and sustained release mechanism is a significant advantage over customary methods,offering improved patient adherence and perhaps reducing side effects associated with fluctuating drug levels.
The Role of benzyl Benzoate
A critical component of this drug delivery system is the solvent used to suspend the drug crystals: benzyl benzoate. This biocompatible solvent,already used in some injectable medications,plays a crucial role in the self-assembly process.
Dr. Reed elaborated on the importance of the solvent: “The solvent, in this case benzyl benzoate, plays a vital role. It’s biocompatible and already used in injectable drugs. Its key property is its limited ability to mix with biological fluids. This allows the drug crystals to self-assemble into a depot once injected under the skin. Without this solvent, the crystals wouldn’t form the controlled-release depot, which would mean the drug wouldn’t last for extended periods.”
The limited miscibility of benzyl benzoate in bodily fluids ensures that the drug crystals remain aggregated, forming the depot that provides sustained drug release.
Tunable Drug Release Rates
One of the most exciting aspects of this technology is the ability to fine-tune the rate at which the drug is released from the depot. This tunability allows researchers to tailor the drug delivery system to specific therapeutic needs, optimizing effectiveness and minimizing potential side effects.
According to dr. Reed, “The researchers can fine-tune the release rate by adjusting the density of the depot. Adding small amounts of polymers, like biodegradable polyesters, modifies the depot’s density. This ability to modulate the release rate allows for a broader range of applications, optimizing the drug’s effectiveness and minimizing potential side effects. This tunability is crucial in adapting the technology for various therapeutic needs.”
This level of control is particularly critically important for drugs with narrow therapeutic windows, where maintaining consistent drug levels is critical for efficacy and safety.
Preclinical Trial Results
Preclinical trials in rats have yielded promising results,demonstrating the feasibility and efficacy of this new drug delivery system. The injections resulted in the formation of stable drug depots that released the drug over a period of three months.
“In preclinical trials using rats,the injections resulted in stable drug depots that released the drug over three months. Importantly, about 85% of the drug remained in the depot after that period, indicating the potential for much longer-term drug action, and it’s expected that the depots could last for more then a year,” Dr. Reed noted.
These findings suggest that this technology has the potential to provide long-lasting drug delivery with a single injection, significantly reducing the burden on patients and healthcare providers.
Retrievability and Potential Applications
While the current research focuses on long-acting drug delivery, the MIT team is also exploring the possibility of making the drug depots retrievable. This would provide an added layer of safety and control, allowing healthcare providers to remove the depot if necesary.
Beyond contraception, this technology has potential applications in a wide range of therapeutic areas, including:
- Mental health disorders: Providing long-acting antipsychotic medications to improve adherence and reduce relapse rates.
- Chronic conditions: Managing diabetes with long-acting insulin formulations.
- Hormone replacement therapy: Delivering consistent hormone levels for women experiencing menopause.
- Pain management: Providing sustained pain relief for chronic pain conditions.
Implications for the U.S. Healthcare System
the widespread adoption of this drug delivery system could have significant implications for the U.S. healthcare system. By reducing the need for frequent injections and improving patient adherence, this technology could lead to:
- Reduced healthcare costs: Fewer clinic visits and hospitalizations due to improved medication adherence.
- Improved patient outcomes: Better management of chronic conditions and reduced risk of complications.
- Increased efficiency: Streamlining medication administration and freeing up healthcare provider time.
the potential cost savings and improved patient outcomes make this technology a promising solution for addressing some of the challenges facing the U.S. healthcare system.
Potential Counterarguments and Considerations
While this new drug delivery system holds great promise, there are also potential challenges and considerations that need to be addressed. These include:
- Adverse reactions: the potential for adverse reactions at the injection site needs to be thoroughly evaluated.
- Long-term safety: Long-term safety studies are needed to assess the potential for delayed complications.
- Cost-effectiveness: The cost-effectiveness of this technology compared to existing methods needs to be carefully evaluated.
- Patient acceptance: Patient acceptance of long-acting injectable medications needs to be considered.
Dr. Reed acknowledged these considerations: “While promising, there are considerations.There might be the potential for adverse reactions at the injection site, and the long-term safety needs thorough evaluation. The cost-effectiveness compared to established methods also needs careful evaluation. It is indeed crucial to conduct thorough studies to fully understand the long-term safety profile and economic implications. Further research is needed to fully assess and confirm its efficacy and its potential application beyond the initial proof-of-concept.”
Addressing these challenges will be crucial for ensuring the successful translation of this technology into clinical practice.
