Instructions
Dosage forms

ATC Code

C02CA04 (Doxazosin)

Active Substance

Doxazosin (Rec.INN registered by WHO)

Clinical-Pharmacological Group

Alpha₁-adrenergic blocker. Antihypertensive agent. Agent used for urination disorders in benign prostatic hyperplasia

Pharmacotherapeutic Group

Antihypertensive agents; peripheral-acting antiadrenergic agents; alpha-adrenergic blockers

Pharmacological Action

A selective competitive blocker of postsynaptic α₁-adrenergic receptors. It causes dilation of peripheral vessels, which leads to a decrease in total peripheral vascular resistance and a reduction in blood pressure. It contributes to an increase in the HDL/total cholesterol ratio and a reduction in the total levels of triglycerides and cholesterol.

With long-term use, regression of left ventricular hypertrophy is observed, platelet aggregation is suppressed, and the tissue content of plasminogen activator increases. Blockade of α₁-adrenergic receptors located in the stroma and capsule of the prostate gland and in the bladder neck leads to a decrease in resistance and pressure in the urethra and a reduction in resistance at its internal orifice. It improves urodynamics and reduces the manifestations of benign prostatic hyperplasia (BPH).

Pharmacokinetics

After oral administration, it is well absorbed from the gastrointestinal tract. C_max in plasma is reached after 1.5-3.6 hours. Plasma protein binding is 98-99%. It is extensively metabolized in the liver. T_1/2 is 19-22 hours. It is excreted mainly through the intestines as metabolites, 5% unchanged; 9% is excreted by the kidneys.

Indications

Benign prostatic hyperplasia (BPH); arterial hypertension (including symptomatic) as part of combination therapy.

Dosage Regimen

The method of application and dosage regimen for a specific drug depend on its form of release and other factors. The optimal dosage regimen is determined by the doctor. It is necessary to strictly adhere to the compliance of the dosage form of a specific drug with the indications for use and dosage regimen.

Tablets

Orally. The dose and regimen are determined individually, depending on the indications and clinical situation.

For BPH, the recommended initial dose is 1 mg/day. Depending on the clinical situation, the dose can be increased to achieve the optimal therapeutic effect. The average daily dose is 2-4 mg. The maximum daily dose is 8 mg.

For arterial hypertension, the dose varies from 1 to 16 mg/day. Treatment is recommended to start with a dose of 1 mg once/day. To achieve the desired reduction in blood pressure, if necessary, the daily dose should be increased gradually, maintaining uniform intervals to 4 mg, 8 mg, and up to the maximum of 16 mg, depending on the severity of the patient’s response to doxazosin. The average daily dose is 2-4 mg.

Contraindications

Hypersensitivity to doxazosin and other quinazoline derivatives; severe hepatic insufficiency (in the absence of experience of use in this category of patients); urinary tract infections; anuria; progressive renal failure; arterial hypotension and tendency to orthostatic disorders (including in history); concomitant obstruction of the upper urinary tract; bladder stones; urinary incontinence due to bladder overflow (paradoxical ischuria); children and adolescents under 18 years of age.

With caution: pulmonary edema caused by mitral valve stenosis or aortic stenosis; heart failure with high cardiac output; right ventricular failure due to pulmonary embolism or exudative pericarditis; left ventricular failure with low filling pressure; cerebrovascular disorders; age over 65 years due to the risk of developing orthostatic symptoms (syncope, dizziness); simultaneous use with phosphodiesterase type 5 (PDE-5) inhibitors (risk of symptomatic arterial hypotension); impaired liver function; pregnancy; during cataract surgery.

Use in Pregnancy and Lactation

Adequate and strictly controlled studies on the safety of doxazosin use during pregnancy and lactation (breastfeeding) have not been conducted. During pregnancy and breastfeeding, it should be used only after consultation with a doctor, in cases where the intended benefit to the mother outweighs the potential risk to the fetus or infant.

Use in Hepatic Impairment

Contraindicated in severe hepatic insufficiency.

Use in Renal Impairment

Contraindicated in progressive renal failure.

Pediatric Use

Contraindicated in children and adolescents under 18 years of age.

Geriatric Use

Should be used with caution in patients over 65 years of age due to the risk of developing orthostatic symptoms (syncope, dizziness).

Special Precautions

After taking the initial dose of doxazosin, orthostatic hypotension may develop (first-dose phenomenon), especially in the standing position. This condition is more often observed in patients with hypovolemia, sodium deficiency, and in the elderly. In this regard, the initial dose is recommended to be taken at bedtime.

Doxazosin should be used with caution in elderly patients due to the possibility of developing orthostatic hypotension. With age, the risk of dizziness, visual disturbances, and fainting increases.

The patient should be informed about the increased risk of orthostatic hypotension when consuming alcohol, prolonged standing, or exercising, as well as in hot weather.

In patients with BPH, Doxazosin can be prescribed both in the presence of arterial hypertension and with normal blood pressure. When used in patients with BPH and normal blood pressure, the change in the latter is insignificant. At the same time, in patients with a combination of arterial hypertension and BPH, monotherapy is possible.

Before starting therapy for BPH, its malignant transformation must be ruled out. Doxazosin does not affect the concentration of prostate-specific antigen (PSA) in blood plasma.

Caution should be exercised when prescribing doxazosin, as well as other drugs that are completely biotransformed in the liver, to patients with impaired liver function, avoiding the prescription of maximum doses.

Intraoperative floppy iris syndrome. Intraoperative floppy iris syndrome (a variant of the “small pupil” syndrome) was observed in some patients during cataract surgery who were receiving or had previously received treatment with α₁-adrenergic blockers. The surgeon must be warned that the patient is currently taking or has previously taken α₁-adrenergic blockers before the surgery.

Priapism. Cases of prolonged erection and priapism have been reported during therapy with α₁-adrenergic receptor blockers, including doxazosin. If an erection persists for more than 4 hours, immediate medical attention should be sought. If therapy for priapism is not carried out immediately, this can lead to damage to the penile tissues and irreversible loss of potency.

There is no clinical experience with the use of doxazosin in children.

Effect on ability to drive vehicles and operate machinery

At the beginning of therapy or when increasing the dose of doxazosin, a sharp decrease in blood pressure is possible, as a result of which dizziness may develop. In this regard, caution must be exercised when driving vehicles and working with complex technical devices that require increased concentration and speed of psychomotor reactions.

Drug Interactions

With simultaneous use with antihypertensive drugs, mutual enhancement of effects is possible.

With simultaneous use with PDE5 inhibitors (sildenafil, tadalafil, vardenafil), symptomatic arterial hypotension may develop in some patients.

It is not recommended to take Doxazosin simultaneously with other α₁-adrenergic receptor blockers.

With simultaneous use with calcium channel blockers, there is some risk of developing pronounced arterial hypotension.

With simultaneous use with nitrates, agents for general anesthesia, tricyclic antidepressants, and ethanol, an enhancement of the hypotensive effect is possible.

With simultaneous use of agents that affect the rate of metabolism in the liver, the metabolism of doxazosin may slow down or accelerate.

NSAIDs (especially indomethacin), estrogens, and sympathomimetic agents may reduce the hypotensive effect of doxazosin. By eliminating the alpha-adrenostimulating effects of epinephrine (adrenaline), Doxazosin can lead to tachycardia and arterial hypotension.

With simultaneous use with sildenafil for the treatment of pulmonary hypertension, the risk of orthostatic hypotension increases.
