Medical Devices

Definition

A medical device functions primarily through physical mechanisms to achieve its therapeutic, diagnostic, or auxiliary purpose. It does not involve pharmacological, immunological, or metabolic action.

Example with Oral Gels: such as Hi-MUPRO oral gels, typically contain ingredients like polymers. Their function is to create a physical protective film over the wound surface, which insulates it from external irritants and keeps it moist. This provides an ideal environment for the tissue to heal on its own.

Pros

• Low Side Effects: As they do not contain medicinal ingredients, they generally do not cause drug-related side effects or allergic reactions, making them relatively safe to use.
• Physical Protection: They provide an immediate physical barrier, effectively relieving pain and accelerating wound healing.
• Non-Antibiotic or Steroid: This avoids issues like antibiotic resistance or dependency that can arise from long-term drug use.

Cons

• Limited Treatment Scope: They are only suitable for minor, non-infectious wounds. Their therapeutic effect is limited for severe ulcers caused by bacterial or fungal infections, or autoimmune diseases.

Drugs/Medicines

Definition

A drug is a chemical substance or mixture used for the diagnosis, treatment, mitigation, or prevention of disease. It primarily affects the body's function through pharmacological, immunological, or metabolic action.

Example with Oral Gels: classified as drugs contain active ingredients such as Benzocaine (a local anesthetic), Triamcinolone Acetonide (a steroid), or Miconazole (an antifungal). Their function is to directly act on the lesion, for example, by relieving pain, reducing inflammation, or killing pathogens.

Pros

• Clear Therapeutic Effect: They provide a clear and effective treatment for specific causes (e.g., pain, inflammation, infection).
• Broad Application: They can be used to treat more severe oral ulcers, inflammation, and even infectious diseases.
• Targeted Treatment: They can fundamentally address oral issues caused by specific pathogens or inflammatory responses.

Cons

• Potential for Side Effects: Containing medicinal ingredients, they may cause allergic reactions, drug resistance, or long-term side effects. For example, steroid oral gels should not be used for extended periods, as they may inhibit the wound's self-healing process.
• Requires Professional Guidance: The use of drugs requires more caution, especially those with prescription-only ingredients, and must be used under the guidance of a physician or pharmacist.
