Bosentan Pharmacology
Bosentan
Metabolism: Hepatic
Elimination: Biliary excretion; less than 3% is recovered in urine.
2.Flushing
3.Itching
4.Runny nose, sore throat, and other cold symptoms
5.Heartburn
2.Coadministration of cyclosporine or glyburide
2.Bosentan use requires hematocrit monitoring due to potential onset of anemia.
3.Hormone-based contraception is not possible in women taking Bosentan, due to a pharmacokinetic a interaction.
4.This drug may make you dizzy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such
2.Cyclosporine :Bosentan trough concentrations may be increased, while cyclosporine plasma levels may be decreased; coadministration is contraindicated.
3.Glyburide :Plasma concentrations of both glyburide and bosentan may be decreased; coadministration is contraindicated.
4.HMG-CoA reductase inhibitors (eg, atorvastatin, lovastatin, simvastatin) :Plasma concentrations of simvastatin and its metabolite may be decreased when coadministered with bosentan. Bosentan is also expected to reduce plasma concentrations of other HMG-CoA reductase inhibitors metabolized by CYP3A4 (ie, atorvastatin, lovastatin). Monitor cholesterol levels and adjust the HMG-CoA reductase inhibitor dose accordingly.
5.Hormonal contraceptives:Plasma concentrations may be reduced by bosentan, decreasing the effectiveness. Women should not rely on hormonal contraception alone when taking bosentan.
6.Ketoconazole :Plasma concentrations of bosentan may be increased. No dosage adjustment is necessary
7.Phosphodiesterase type 5 inhibitors (eg, sildenafil) :Coadministration may elevate bosentan plasma concentrations, increasing the pharmacologic effects and risk of toxicity. Phosphodiesterase type 5 inhibitor concentrations may be reduced, decreasing the pharmacologic effects. Coadminister these agents with caution
8.Rifampin :Coadministration may increase bosentan trough concentrations after the first concomitant dose and decrease bosentan trough concentrations at steady state
9.Ritonavir-containing regimens :Coadministration may increase bosentan trough concentrations. In patients receiving ritonavir for at least 10 days, start bosentan at 62.5 mg once daily or every other day based on tolerability. In patients receiving bosentan, stop bosentan at least 36 h before starting ritonavir. At least 10 days after starting ritonavir, resume bosentan at 62.5 mg once daily or every other day based upon tolerability.
10.Warfarin :Warfarin plasma concentrations may be decreased by bosentan. Because warfarin has a narrow therapeutic index, monitor coagulation parameters and adjust the warfarin dose as needed
PO 62.5 mg twice daily for 4 wk, then increase to maintenance dosage of 125 mg twice daily. In patients with a body weight less than 40 kg, the recommended maintenance dosage is 62.5 mg twice daily.
Dosage adjustments are necessary in patients developing aminotransferase abnormalities
Symptoms of overdose may include:
1.Headache
2.Upset stomach
3.Vomiting
4.Fast heartbeat
5.Fainting
6.Dizziness
7.Blurred vision
