Clinical Description

Definition of Underdosing

Underdosing occurs when a patient receives less than the prescribed amount of medication, which can lead to inadequate therapeutic effects. In the context of antineoplastic and immunosuppressive drugs, underdosing can significantly impact treatment outcomes, potentially leading to disease progression or increased susceptibility to infections due to insufficient immune suppression.

Antineoplastic Drugs

Antineoplastic drugs are primarily used in the treatment of cancer. They work by inhibiting the growth and proliferation of cancer cells. Common classes of antineoplastic agents include:

• Alkylating agents: These drugs damage DNA, preventing cancer cell division.
• Antimetabolites: They interfere with DNA and RNA synthesis.
• Plant alkaloids: These disrupt the mitotic spindle, preventing cell division.
• Hormonal agents: These block hormones that fuel certain cancers.

Immunosuppressive Drugs

Immunosuppressive drugs are used to suppress the immune response, often necessary in conditions such as autoimmune diseases or following organ transplants. They help prevent the body from rejecting transplanted organs and reduce inflammation in autoimmune disorders. Common immunosuppressive agents include:

• Corticosteroids: These reduce inflammation and suppress the immune response.
• Calcineurin inhibitors: These inhibit T-cell activation.
• Antimetabolites: Similar to their use in cancer treatment, they also suppress immune cell proliferation.

Clinical Implications of Underdosing

Risks and Consequences

1. Cancer Progression: Inadequate dosing of antineoplastic agents may allow cancer cells to survive and proliferate, leading to treatment failure and disease progression[1].
2. Increased Infection Risk: For patients on immunosuppressive therapy, underdosing can result in insufficient immune suppression, increasing the risk of infections, which can be particularly severe in immunocompromised patients[2].
3. Therapeutic Failure: Overall, underdosing can lead to suboptimal therapeutic outcomes, necessitating adjustments in treatment plans and potentially leading to more aggressive interventions later on[3].

Identification and Management

Healthcare providers must be vigilant in monitoring medication adherence and dosing. Strategies to manage underdosing include:

• Patient Education: Ensuring patients understand the importance of adhering to prescribed dosages.
• Regular Monitoring: Frequent assessments of drug levels and clinical response can help identify underdosing early.
