Drug interaction
Effect of other drugs on the pharmacokinetics of sildenafil
In vitro studies. Sildenafil metabolism occurs mainly under the action of cytochrome P450 (CYP) 3A4 (main pathway) and 2C9 (additional pathway) isoenzymes, so inhibitors of these isoenzymes may decrease sildenafil clearance, and inducers increase sildenafil clearance accordingly.
In vivo studies. Co-administration of CYP3A4 isoenzyme inhibitors (such as ketoconazole, erythromycin, cimetidine) and sildenafil reduces its clearance.
Ritonavir increases sildenafil AUC 11-fold, co-administration of these drugs is not recommended.
When sildenafil (100 mg 1 time / day) and HIV protease inhibitor and CYP3A4 isoenzyme inhibitor saquinavir are administered concomitantly with a sustained blood saquinavir concentration (1200 mg 3 times daily), sildenafil Cmax is increased by 140% and AUC is increased by 140% - 210%. Sildenafil has no effect on the pharmacokinetics of saquinavir. More potent CYP3A4 isoenzyme inhibitors, such as ketoconazole and itraconazole, may presumably cause more pronounced changes in the pharmacokinetics of sildenafil.
Using 100 mg of sildenafil 1 time / day with erythromycin, specific inhibitor of CYP3A4, against the background of achieving a constant concentration of erythromycin in the blood (500 mg 2 times / day for 5 days) leads to an increase in AUC of sildenafil by 182%. In healthy male volunteers, azithromycin (500 mg / d for 3 days) did not affect AUC, Cmax, Tmax, excretion rate constant, and T1 / 2 of sildenafil or its major circulating metabolite. Cimetidine (800 mg), a nonspecific CYP3A4 inhibitor, when co-administered with sildenafil (50 mg) in healthy volunteers caused a 56% increase in plasma sildenafil concentration.
Grapefruit juice, a weak CYP3A4 inhibitor, can moderately increase plasma concentrations of sildenafil.
Single use of antacids (magnesium hydroxide / aluminum hydroxide) does not affect the bioavailability of sildenafil. srdk srpc While no special pharmacokinetic studies have been performed, the population pharmacokinetic analysis did not reveal any changes in the pharmacokinetics of sildenafil, such as tolbutide , loop and potassium-sparing diuretics, ACE inhibitors, BPCs, beta-blockers or isoenzyme inducersCYP450 (such as rifamp ycin, barbiturates).
Nicorandil is a hybrid of nitrate and potassium channel activator. Due to the presence of the nitrate component, it can enter into serious interactions with sildenafil.
Effect of sildenafil on other drugs
In vitro studies. Sildenafil is a weak inhibitor of cytochrome P450 isoenzymes 1A2, 2C9, 2C19, 2D6, 2E1, and 3A4 (IR50 150 μmol). When sildenafil is used at the recommended doses, its Cmax in the blood plasma is about 1 μmol, so it is unlikely that Vizarsin® can affect the clearance of substrates of these isoenzymes.
There are no data on the interaction of sildenafil with non-specific PDE inhibitors, such as theophylline or dipyridamole.
In vivo studies. Given the known effect of sildenafil on NO / cGMP, it may potentiate the hypotensive action of nitrates, so its concomitant use with NO donors or nitrates in any form is contraindicated.
The concomitant use of sildenafil and alpha-blockers may lead to symptomatic arterial hypotension in selected susceptible patients. Arterial hypotension usually develops 4 hours after taking sildenafil.
In three special studies on drug interactions in patients with benign prostatic hyperplasia with stable hemodynamics, sildenafil (25, 50 or 100 mg) was used concomitantly with doxazosin (4 and 8 mg). In all three studies, an average additional decrease in BP in the lying position by 7/7 mm Hg was observed. in., 9/5 mm Hg. Art. and 8/4 mm Hg. Art., and additional reduction in blood pressure in the standing position at 6/6 mm Hg. in., 11/4 mm Hg. Art. and 4/5 mm Hg. Art. respectively. With the concomitant use of sildenafil and doxazosin in patients with stable hemodynamics, rare cases of symptomatic postural hypotension have been observed on the background of doxazosin administration. In these described cases, dizziness or a feeling of lightness developed, but without the development of fainting states.
No significant interactions were observed with sildenafil (50 mg) and tolbutamide (250 mg) or warfarin (40 mg) co-metabolized with CYP2C9.
Sildenafil (50 mg) does not potentiate the increase in bleeding time caused by acetylsalicylic acid (150 mg).
Sildenafil (50 mg) does not potentiate the antihypertensive effect of alcohol in healthy volunteers with a maximum blood alcohol content of 80 mg / dL.
Summary of available data on the following drugs: diuretics, beta-blockers, ACE inhibitors, angiotensin receptor blockers, vasodilators and antihypertensive agents of central action, blockers of adrenergic neurons, BKKi alpha-blockers found no difference in adverse reaction profile in patients taking sildenafil or placebo at the same time. In a specially conducted study, sildenafil (100 mg) was used concomitantly with amlodipine in patients with hypertension and further reduced SAD in the supine position by an average of 8 mm Hg. and DBP - by 7 mm Hg. Art. This additional reduction in blood pressure turned out to be the same as when using only sildenafil in healthy volunteers.
