Troches, also known as lozenges or pastilles, are rapidly gaining recognition as a versatile and effective method for delivering medication. Traditionally associated with soothing sore throats, troches now play a far broader role, helping patients manage everything from hormone therapies to chronic pain. As healthcare providers seek alternatives to pills and injectables, this discreet, convenient delivery format is experiencing renewed interest across hospitals, compounding pharmacies, and even telemedicine startups.
While oral and injectable medications remain the norm, troches bridge the gap, offering a tailored approach especially suited for those with difficulty swallowing, those needing rapid absorption, and patients requiring personalized dosing. Understanding how troches work, their unique benefits, and their optimal use cases can empower patients and clinicians alike to make more informed healthcare decisions.
What Are Troches? Understanding the Format and Function
Troches are small, dissolvable tablets designed to be held in the mouth—typically between the cheek and gum—allowing the medication to absorb directly into the bloodstream through the oral mucosa. Unlike conventional pills, which must be swallowed and processed through the digestive tract, troches enable what’s called transmucosal (or buccal) delivery.
They are produced by compounding pharmacies in multiple shapes, flavors, and doses, tailored to meet individual patient needs. Common active ingredients found in troches include hormones (such as estrogen, testosterone, or progesterone), pain medications, anti-fungals, and even certain vitamins or supplements.
Troches vs. Other Oral Dosage Forms
It’s useful to distinguish troches from related forms like sublingual tablets (dissolved under the tongue) or medicated gummies:
- Troches: Slow dissolve in the oral cavity, often flavored, designed for steady absorption.
- Sublingual tablets: Placed under the tongue for rapid absorption; usually smaller and dissolve faster.
- Gummies: Chewed and swallowed, so they act more like traditional oral medications.
Each format has its own advantages and disadvantages, but troches stand out for their slow, controlled delivery and customizability.
Key Benefits of Troches for Patients
Troches hold distinct advantages over traditional forms like pills or injections, particularly in scenarios where precision, patient comfort, or bypassing the digestive system is desirable.
Enhanced Absorption and Avoidance of First-Pass Metabolism
A major pharmacological benefit lies in the avoidance of “first-pass hepatic metabolism.” When most oral drugs are swallowed, they enter the stomach and intestines before passing through the liver, where part of the drug may be inactivated. Troches, by delivering drugs directly through the mucous membranes, bypass much of the liver’s initial filtration, often leading to:
- Faster onset of action
- More consistent blood concentrations
- Potentially lower required dosages to achieve therapeutic effect
This feature is particularly valuable for hormones and other drugs where tight dose control is critical.
Improved Patient Compliance and Comfort
Troches are favored by patients who find it difficult to swallow large tablets or capsules. They also eliminate the need for injections, which can be intimidating or inconvenient for many.
A 2020 survey of patient preference found that those prescribed compounded troches for hormone replacement reported higher satisfaction and fewer gastrointestinal complaints compared to conventional pills, supporting broader anecdotal reports from healthcare providers.
Customization and Versatility
Pharmacies can compound troches with tailored doses and various flavors, making them more palatable for children, older adults, and individuals with sensory or taste sensitivities. Additionally, troches allow for precise dose adjustments, which can be invaluable in hormone therapy and pain management, where “one-size-fits-all” solutions rarely suffice.
“Troches allow for medication to be dosed with exceptional precision and increased patient comfort, which is especially beneficial in pediatric care and hormone therapies,” notes Dr. Karen Robbins, PharmD, a compounding pharmacy expert.
Beyond hormones, compounded troches may also be used in dental medicine, palliative care, and managing chronic conditions where flexible dosing is essential.
Clinical Uses: Who Can Benefit from Troches?
Troches serve an important role in several fields of medicine where other options may fall short.
Hormone Replacement Therapy (HRT)
One of the most widespread uses—especially in the United States and Australia—is in bioidentical hormone replacement therapy (BHRT) for women in menopause, as well as men with low testosterone. Troches offer precise hormonal dosing and can combine multiple hormones in one formulation.
Case Example
A compounding pharmacy in Melbourne reported that nearly 40% of their menopausal patients preferred troches to capsules due to ease of use and improved symptom control, highlighting just how impactful the format can be for long-term therapies.
Pain Management and Palliative Care
For patients in palliative care, swallowing can become challenging, making troches a dignified alternative for ongoing comfort. Pain, anti-nausea, and anti-fungal medications are often prepared in troche form for these scenarios.
Pediatric and Geriatric Applications
Children and older adults frequently experience difficulties with large pills. Troches—customized by flavor and dose—are more easily tolerated, promoting adherence and uptake of essential medications.
Considerations and Limitations
Despite their clear advantages, troches aren’t suitable for all medications or situations.
Limitations
- Not for all drugs: Only certain medications can be effectively absorbed through oral mucosa.
- Taste masking challenges: Strong-tasting actives may be harder to flavor successfully.
- Dosing consistency: While generally reliable, uneven dissolution or incorrect placement in the mouth can affect absorption.
- Storage: Unlike standard tablets, some troches may require refrigeration or protection from humidity.
Regulatory and Quality Considerations
Most troches are produced in specialized compounding pharmacies rather than large-scale manufacturers. This means quality and consistency depend on the skill and protocol adherence of the compounding pharmacist. In the U.S., the FDA regulates compounded medications primarily for safety, but efficacy data is sometimes limited compared to mass-produced pharmaceuticals.
How Troches Work: The Science of Buccal and Sublingual Absorption
The oral mucosa, especially the cheek and tissue beneath the tongue, is richly vascularized, allowing medication to quickly diffuse into the bloodstream. The troche dissolves slowly—usually over 10 to 30 minutes—enabling steady absorption.
Factors influencing effectiveness include:
- Placement in the mouth (cheek vs. under tongue)
- Saliva production (too much or too little can affect dissolution)
- Individual mucosal characteristics
A 2019 study in the Journal of Drug Delivery Science and Technology suggested that buccal formulations like troches could achieve therapeutic blood levels with less drug than traditional oral tablets, further minimizing systemic side effects.
The Future of Troches: Innovation and Trends
Troches are experiencing increased adoption as telemedicine and personalized medicine trends accelerate. With more patients seeking tailored treatments and remote care, compounding pharmacies are innovating with new flavors, advanced release profiles, and combined formulations.
Emerging areas, such as medical cannabis, nutraceuticals, and cognitive enhancement supplements, are also seeing troche-based options come to market—the result of ongoing research into patient-centric drug delivery systems.
Conclusion: Troches in Modern Therapy
Troches have evolved from simple throat soothers into precise, patient-friendly vehicles for medication delivery. They’re reshaping options in hormone therapy, pain management, and chronic care by providing a customizable, comfortable alternative to conventional dosage forms. As compounding techniques improve and awareness grows, troches will likely play an increasing role in advancing patient-centered pharmaceuticals.
For anyone considering troches—either as a patient or prescriber—consultation with knowledgeable clinicians and reputable compounding pharmacists is essential. Personalized medicine continues to move beyond the pill, and troches are at the forefront of this meaningful shift.
