Summary
Sodium nitroprusside (SNP) infusion can rarely cause Toxic Epidermal Necrolysis (TEN), a severe skin reaction. This case highlights a potential link between SNP and sequential IgE and non-IgE mediated hypersensitivity reactions.
Area of Science:
- Clinical Medicine
- Pharmacology
- Dermatology
Background:
- Sodium nitroprusside (SNP) is a critical parenteral antihypertensive agent for severe hypertension.
- Toxic Epidermal Necrolysis (TEN) is a rare, severe, often drug-induced mucocutaneous reaction with high mortality.
- Understanding drug-induced hypersensitivity reactions is crucial for patient safety.
Observation:
- A 15-year-old female on hemodialysis developed a maculopapular rash minutes after SNP infusion for hypertension.
- The rash rapidly progressed to widespread skin detachment, consistent with TEN, within 72 hours.
- Skin biopsy confirmed the diagnosis of Toxic Epidermal Necrolysis.
Findings:
- This case presents the first reported association between Sodium Nitroprusside and Toxic Epidermal Necrolysis in English literature.
- The patient experienced a rare sequential IgE and non-IgE mediated hypersensitivity reaction.
- Clinical data on SNP-induced hypersensitivity, particularly TEN, is notably scarce.
Implications:
- Clinicians should be aware of the potential for SNP to induce severe hypersensitivity reactions like TEN.
- This case underscores the need for vigilance and prompt recognition of adverse drug reactions during antihypertensive therapy.
- Further research into the mechanisms of SNP-induced hypersensitivity may improve patient management and outcomes.

01:23Antihypertensive Drugs: Vasodilators
Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...
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...
01:202° Amines to N-Nitrosamines: Reaction with NaNO2
Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.
01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
01:25Bioactivation and Tissue Toxicity
Bioactivation is a metabolic process that transforms less reactive substances into highly reactive metabolites, initiating tissue toxicity. This transformation can lead to various toxic effects, including carcinogenesis and teratogenesis. Reactive metabolites are classified into two main types: electrophiles and free radicals.Electrophiles are electron-deficient species and are produced primarily by the enzyme cytochrome P-450 during the metabolism of compounds containing carbon, nitrogen, or...

In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
