Magnesium stearate: an underestimated allergen
Journal of Biological Regulators and Homeostatic Agents
|December 18, 2012
Summary
Magnesium stearate, a common pharmaceutical excipient, can cause allergic reactions. This case study details a 28-year-old woman who developed urticaria from this widely used substance.
Area of Science:
- Pharmacology
- Allergology
- Materials Science
Background:
- Magnesium stearate is a widely utilized excipient in pharmaceutical formulations.
- It serves as a lubricant and stabilizer in tablets and capsules.
- Its presence as a food additive is also common.
Observation:
- A 28-year-old female patient presented with an allergic reaction.
- The reaction manifested as urticarial skin lesions.
- The patient had exposure to magnesium stearate.
Findings:
- This report documents the first known case of an allergic reaction to magnesium stearate.
- The patient experienced urticaria attributed to magnesium stearate exposure.
- Diagnostic confirmation of the allergy was established.
Implications:
- Highlights the potential for hypersensitivity to common pharmaceutical excipients.
- Suggests the need for increased awareness among clinicians regarding magnesium stearate allergy.
- May prompt further investigation into the immunogenic properties of magnesium stearate.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

01:30Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...

Overview
01:30Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
01:27Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
01:29Asthma-I: Introduction
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
