Abstract:
A 73-year-old woman presented with an acute exacerbation of her long-standing psoriasis. Ciclosporin was commenced due to the severity of her symptoms resulting in remission within 2 weeks. Full blood count, urea and electrolytes following initiation of treatment were unremarkable, although she complained of muscle aches, which was attributed to her known multiple sclerosis. Three weeks later she was admitted to the hospital with diarrhoea and vomiting. Repeat blood tests revealed raised creatinine (528 μmol/L (normal range (NR) n=45-84 μmol/L)), urea (32.6 mmol/L (NR 2.5-7.8 mmol/L)) and creatine kinase (6792 IU/L (NR 25-200 IU/L)) levels and reduced estimated glomerular filtration rate of 7. A diagnosis of acute kidney injury secondary to rhabdomyolysis was made due to an interaction between ciclosporin and simvastatin, precipitated by the dehydration from gastroenteritis. Haemofiltration was required to stabilise her renal function and she made a complete recovery.

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.
