Pravastatin

Pharmacodynamic effects

Possible increased risk of HMG CoA inhibitor toxicity.

Recommendations

Use this combination with caution.

Start with a small dosage. Monitor closely for signs and symptoms of toxicity and adjust dosage as a function of efficacy and tolerance.

Alternative solution(s)

Monitor

Symptoms of toxicity associated with hypolipidemic agents : gastrointestinal effects, fatigue and muscular weaknesses, myalgias, muscular cramps, myopathies, rhabdomyolysis and myoglobinuria leading to renal insufficiency.

Comment

The coadministration is generally well tolerated. Start with a low dose of pravastatin because a wide individual variability was reported.

Ref #2380 : Co-administration of pravastatin with darunavir/ritonavir increased pravastatin AUC by 21%.

Réf #2129 : However, in another study with darunavir/ritonavir, an average increase in pravastatin SSC of 81% was observed with increases of up to 5-fold in some subjects.

Réf #3391 : Case report of rhabdomyolysis in a patient on elvitegravir/cobicistat and pravastatin/fenofibrate.
