ODT Formulations vs Conventional Tablets: Advancing Modern Oral Drug Delivery Systems

Oral drug delivery systems continue to be one of the most widely used approaches in modern healthcare because of their convenience, accurate dosing, and patient acceptance. Among the various types of oral drug delivery system technologies, the oral solid dosage form has remained a preferred choice in the pharmaceutical industry for decades. However, traditional oral tablets are not always easy for every patient population to consume, especially paediatric, geriatric, and dysphagic patients who often experience difficulty swallowing conventional tablets, as highlighted in studies published by the National Centre for Biotechnology Information.1-3

To address these challenges, orodispersible tablets, also known as oral disintegrating tablets or fast disintegrating tablets, have emerged as an advanced approach in pharmaceutical formulation development. Unlike conventional tablets, orodispersible formulations are designed to rapidly disintegrate in the mouth without the need for water, improving convenience and supporting better medication adherence solutions. Research published in pharmaceutical studies has shown that orodispersible tablet technologies are increasingly being adopted because of their patient-friendly administration and improved compliance potential.2,4

In recent years, the pharmaceutical industry has also focused heavily on patient-centric formulation innovation. Modern orally disintegrating tablet technologies combine rapid disintegration properties, taste-masking approaches, and optimised excipient selection to create more advanced oral drug delivery systems that improve the overall medication experience for patients.5

Understanding Conventional Tablets and Orodispersible Formulations

Conventional Tablets

Conventional tablets are among the most commonly used oral solid dosage form technologies in the pharmaceutical industry. These tablets are designed to be swallowed with water and disintegrate after reaching the stomach. Their manufacturing process, dosage accuracy, and long-term stability have made them a standard choice across multiple therapeutic categories.6

Orodispersible Tablets

Orodispersible tablets (ODTs), are formulated to rapidly disintegrate in the mouth without requiring water. ODT formulations are specifically developed to improve patient convenience and support easier medicine administration, especially for paediatric, geriatric, and dysphagic patients.1-3

The Key Difference in Formulation Development

The difference between conventional tablets and ODT formulations is not limited to administration alone. Conventional tablets are primarily optimised for stability and controlled disintegration inside the gastrointestinal tract. In contrast, ODT formulations involve advanced pharmaceutical formulation development approaches using superdisintegrants, taste-masking technologies, and specialised excipients that allow rapid tablet dispersion while maintaining tablet strength and performance.7

Why ODT Technologies Are Gaining Attention

As healthcare moves toward patient-centric treatment approaches, ODTs are becoming an increasingly important part of modern oral drug delivery systems. Their convenience, ease of administration, and potential role in medication adherence solutions are driving growing interest in ODT technologies across the pharmaceutical industry.1

Why the Pharmaceutical Industry Needed ODT Formulations

The development of ODTs was largely driven by the growing need for more patient-friendly oral drug delivery systems. While conventional oral tablets remain widely used, several patient populations continue to face challenges with traditional oral solid dosage forms.

Why Traditional Tablets Became Challenging

  • Many paediatric and geriatric patients experience difficulty swallowing conventional tablets.1
  • Dysphagia and swallowing-related issues can reduce medication adherence and treatment effectiveness.3
  • Patients with neurological disorders, psychiatric conditions, and chronic illnesses often require easier-to-administer dosage forms.8
  • In patients with dysphagia, carers and healthcare professionals often resort to crushing conventional tablets to make administration easier.12
  • While this practice may appear convenient, it can introduce several risks, including inaccurate dosing, altered drug release characteristics, reduced treatment effectiveness, and an increased likelihood of medication errors.13
  • Crushing certain formulations may also affect drug stability, palatability, and patient acceptance, potentially impacting overall treatment outcomes.13

These challenges have strengthened the need for patient-friendly dosage forms such as ODTs, which can be administered without the need for swallowing intact tablets or modifying the original formulation.

The Growing Need for Patient-Centric Formulations

  • Modern pharmaceutical formulation development is increasingly focused on patient convenience and treatment accessibility.
  • Healthcare providers are prioritising medication adherence solutions that improve the overall patient experience.
  • The pharmaceutical industry is moving toward oral drug delivery systems that are simpler and more comfortable for patients to consume.

How ODT Formulations Addresses these Challenges1-3 8

  • ODTs rapidly disintegrate in the mouth without requiring water.
  • ODT formulations improve ease of administration for patients with swallowing difficulties. towards patient-centric pharmaceutical formulation development.
  • ODTs are also beneficial during travel, emergency situations, and outpatient care settings.

The Industry Shift Toward ODT Technologies

  • Research studies highlight that orally disintegrating tablet technologies improve patient acceptability and compliance in oral drug delivery systems.1-3 8

ODT formulations are becoming an important part of patient-centric pharmaceutical innovation strategy within modern healthcare.

Key Advantages of ODTs Over Conventional Tablets1-3 8

The increasing adoption of ODTs reflects the pharmaceutical industry's growing focus on patient-centric oral drug delivery systems. Compared to conventional oral tablets, ODT formulations offer several advantages that improve convenience, accessibility, and the overall medication experience.

Improved Patient Convenience

  • ODTs rapidly disintegrate in the mouth and can be administered without water.
  • This makes them particularly useful for patients who may not have immediate access to water.
  • The simplified administration process improves ease of use across various healthcare settings.

Better Support for Patients with Swallowing Difficulties

  • Swallowing conventional tablets can be challenging for certain patient populations.
  • ODT formulations offer a patient-friendly alternative dosage form for paediatric, geriatric, and other patients suffering from swallowing difficulties.
  • By eliminating the need to swallow an intact tablet, ODTs can improve treatment acceptance and patient comfort.

Supports Medication Adherence

  • Medication adherence remains an important factor in successful treatment outcomes.
  • Patients are more likely to follow prescribed therapies when medicines are easy to administer.
  • The convenience and ease of administration offered by ODTs can contribute to improved compliance, particularly in long-term therapies.

Rapid Disintegration Performance

  • ODT formulations are specifically designed to disintegrate within less than 3 mins after coming into contact with saliva.
  • The rapid disintegration process creates a more convenient medication experience compared to traditional oral tablets.

Advanced formulation technologies such as super disintegrants play a critical role in achieving this performance.

Formulation Differences Between ODTs and Conventional Tablets

The difference between conventional oral tablets and ODTs goes beyond administration convenience. Both dosage forms follow different pharmaceutical formulation development approaches based on how the medicine is intended to perform inside the body.

Conventional Tablet Formulations 9

Conventional oral tablets are primarily designed to:

  • Be swallowed with water
  • Remain stable during storage and transportation
  • Disintegrate after reaching the stomach
  • Release the active ingredient within the gastrointestinal tract

These formulations generally focus on mechanical strength, stability, and controlled disintegration performance within traditional oral drug delivery systems.

ODT Formulations1-3, 7, 8

To achieve this rapid disintegration performance, ODTs often incorporate:

  • Superdisintegrants
  • Specialised excipients
  • Taste-masking technologies
  • Optimised compression techniques

These formulation strategies help maintain tablet integrity while ensuring fast dispersion and improved patient acceptability.

The Role of Superdisintegrants in ODT Technologies 10

One of the key formulation differences in orodispersible tablets is the use of super disintegrants. This ingredient rapidly absorbs saliva and promotes quick tablet breakdown inside the oral cavity.

Commonly used super disintegrants include:

  • Crospovidone
  • Croscarmellose sodium
  • Sodium starch glycolate

These excipients play a critical role in improving the disintegration efficiency of ODT formulations.

The Role of Superdisintegrants in ODT Technologies 7

Compared to conventional tablets, ODT formulations require more advanced pharmaceutical formulation development because they must balance multiple performance factors simultaneously.

Key formulation considerations include:

  • Rapid disintegration time
  • Pleasant mouthfeel
  • Effective taste masking
  • Mechanical strength
  • Moisture sensitivity
  • Drug stability

As a result, ODT technologies often involve advanced manufacturing approaches such as direct compression and freeze-drying techniques.
