Gooch RA, Kahn JM.; JAMA. 2014 Feb 12;311(6):567-8.
Intensive care is a substantial financial burden on the US health care system, with spending on critical illness exceeding $80 billion per year, approximately 3% of all health care spending and nearly 1% of the gross domestic product. In contrast, the United Kingdom spends only 0.1% of its gross domestic product on critical care services, with no evidence of worse patient outcomes and similar life expectancies as in the United States...
Gandhi S, Fleet JL, Bailey DG, McArthur E, Wald R, Rehman F, Garg AX.; JAMA. 2013 Dec 18;310(23):2544-53.
IMPORTANCE: Calcium-channel blockers are metabolized by the cytochrome P450 3A4 (CYP3A4; EC 188.8.131.52) enzyme. Blood concentrations of these drugs may rise to harmful levels when CYP3A4 activity is inhibited. Clarithromycin is an inhibitor of CYP3A4 and azithromycin is not, which makes comparisons between these 2 macrolide antibiotics useful in assessing clinically important drug interactions.
