Abstract:
For more than 50 years, methotrexate (MTX), when used in low doses, has been one of the most commonly used drugs in the treatment of psoriasis. It has immunosuppressive as well as anti-inflammatory properties. Pancytopenia, hepatic dysfunction, respiratory toxicity, and acute renal failure are some of the reported side effects. This is a case study of a patient who had developed florid symptoms of methotrexate toxicity as a result of erroneous overdosing of methotrexate, which was given to her for psoriasis management.
Insights
Methotrexate (MTX) is a common psoriasis treatment, but overdosing can cause severe toxicity. This case highlights the critical need for accurate dosing to prevent serious side effects.
Area of Science:
- Dermatology
- Pharmacology
- Toxicology
Background:
- Methotrexate (MTX) is a widely used immunosuppressive and anti-inflammatory drug for psoriasis treatment.
- Low-dose MTX has been a mainstay in psoriasis management for over 50 years.
- Potential side effects include pancytopenia, liver dysfunction, respiratory issues, and kidney failure.
Observation:
- This case study details a patient experiencing severe methotrexate toxicity.
- The toxicity resulted from an accidental overdose of methotrexate prescribed for psoriasis.
- The patient presented with pronounced symptoms indicative of MTX toxicity.
Findings:
- Erroneous overdosing of methotrexate led to florid symptoms of toxicity.
- The patient's condition underscores the narrow therapeutic index of methotrexate.
- Accurate dosage is paramount in preventing MTX-related adverse events.
Implications:
- This case emphasizes the importance of meticulous medication management in dermatology.
- Healthcare providers must ensure precise methotrexate dosing to avoid life-threatening toxicity.
- Patient safety protocols should be reinforced to prevent medication errors in chronic disease management.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
