Unfortunately any amount exceeding 2 mg of bupe will block for at least 48 hours. 16 mg is a shitload. For me (everyone is different), it takes up to four days for this much to stop blocking enough for any agonist to be worth it. 1 point 3 years ago. Beta Blocker is an important drug widely used for maintaining the blood pressure. The drug is usually prescribed to treat the high blood pressure. The main ingredient of the drug is beta-adrenergic blocking substance. It actually blocks the adrenalin substance in the body in order to control the blood pressure. However, if the prescribed dose.

Pharmacologic Category

  • Alpha1 Blocker
  • Antihypertensive

Pharmacology

Hypertension: Competitively inhibits postsynaptic alpha1-adrenergic receptors which results in vasodilation of veins and arterioles and a decrease in total peripheral resistance and blood pressure; ~50% as potent on a weight by weight basis as prazosin.

BPH: Competitively inhibits postsynaptic alpha1-adrenergic receptors in prostatic stromal and bladder neck tissues. This reduces the sympathetic tone-induced urethral stricture causing BPH symptoms.

Metabolism

Extensively hepatic to active metabolites; primarily via CYP3A4; secondary pathways involve CYP2D6 and 2C9

Excretion

Feces (~63%, primarily as metabolites [4.8% as unchanged]); urine (9%, primarily as metabolites)

Time to Peak

Serum: Immediate release: 2 to 3 hours; Extended release: 8 ± 3.7 to 9 ± 4.7 hours

Duration of Action

>24 hours

Half-Life Elimination

Immediate release: ~22 hours; Extended release: 15 to 19 hours

Protein Binding

~98%

Special Populations: Hepatic Function Impairment

Immediate release: 40% increase in exposure in mild impairment (Child-Pugh class A).

Special Populations: Elderly

Extended release: Cmax and AUC increased 27% and 34% respectively in elderly patients.

Use: Labeled Indications

Benign prostatic hyperplasia: Treatment of signs and symptoms of benign prostatic hyperplasia (BPH).

Hypertension (immediate release only): Management of hypertension. Note: Alpha blockers are not recommended as first line therapy (ACC/AHA [Whelton 2017]).

Off Label Uses

Ureteral calculi expulsion

Use of alpha-1 adrenergic blockers, including doxazosin, for treating ureteral calculi is supported by data from a meta-analysis as well as numerous controlled trials. Tamsulosin has the most data, but doxazosin has also demonstrated efficacy in facilitating expulsion of ureteral stones (<10 mm) as medical therapy alone or as an adjunct to shock wave lithotripsy and ureteroscopy. Some trials indicate a class effect of alpha-1 adrenergic blockers, with doxazosin reported to be equally effective as terazosin, tamsulosin, and alfuzosin [Ates 2012], [Campshroer 2018], [Gurbuz 2011], [Hollingsworth 2016], [Zehri 2010]

American Urological Association/Endourological Society guidelines and European Association of Urology guidelines recommend use of alpha-1 blockers, including doxazosin, for treating ureteral calculi [AUA/ES [Assimos 2016]], [EAU [Türk 2019]]

Contraindications

Hypersensitivity to doxazosin, other quinazolines (eg, prazosin, terazosin), or any component of the formulation.

Canadian labeling: Additional contraindications (not in US labeling): Galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption.

Dosing: Adult

BPH: Oral:

Immediate release: Initial: 1 mg once daily; may titrate (by doubling the daily dose [eg, to 2 mg, then 4 mg, then 8 mg]) at 1- to 2-week intervals up to 8 mg once daily based on patient response and tolerability (maximum: 8 mg/day).

1 Blocker 1 4 8 Mg

Reinitiation of therapy: If therapy is discontinued for several days, restart at 1 mg dose and titrate using initial dosing regimen.

Extended release: 4 mg once daily; may titrate based on response and tolerability every 3 to 4 weeks to 8 mg once daily (maximum: 8 mg/day).

Reinitiation of therapy: If therapy is discontinued for several days, restart at 4 mg dose and titrate using initial dosing regimen.

Note: Conversion to extended release from immediate release: Omit final evening dose of immediate release prior to starting morning dosing with extended release product; initiate extended release product using 4 mg once daily.

Warnings/Precautions

Concerns related to adverse effects:

• Allergic reactions: May occur, including skin rash, urticaria, pruritus, angioedema, and respiratory symptoms.

• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery or driving).

• Floppy iris syndrome: Intraoperative floppy iris syndrome has been observed in cataract surgery patients who were on or were previously treated with alpha1-blockers; there appears to be no benefit in discontinuing alpha-blocker therapy prior to surgery. May require modifications to surgical technique.

• Hematologic effect: Decreases in white blood cells (WBC) and neutrophil count have been reported; WBC and neutrophils returned to normal after discontinuation.

• Orthostatic hypotension/syncope: May cause orthostatic hypotension and syncope within a few hours after dosing, but may occur later; anticipate a similar effect if therapy is interrupted for a few days, if dosage is increased, or if another antihypertensive drug, PDE-5 inhibitor, or nitrates are introduced. Use with caution in patients with symptomatic orthostatic hypotension.

• Priapism: Priapism has been associated with use (rarely); seek immediate medical assistance for erections lasting longer than 4 hours.

Disease-related concerns:

• Cardiovascular disease: Use with caution in patients with heart failure, angina pectoris, or recent acute myocardial infarction (within the last 6 months). If symptoms of angina pectoris appear or worsen, discontinue use. In a scientific statement from the American Heart Association, doxazosin has been determined to be an agent that may exacerbate underlying myocardial dysfunction (magnitude: moderate) (AHA [Page 2016]).

• Hepatic impairment: Use with caution in patients with mild to moderate impairment (Child-Pugh class A and B); monitor blood pressure and for symptoms of hypotension. Not recommended in severe impairment (Child-Pugh class C) (extensively metabolized).

• Prostate cancer: Rule out prostatic carcinoma before beginning therapy (many symptoms of BPH and prostate cancer are similar).

Dosage form specific issues:

• Extended release: Consists of drug within a nondeformable matrix; following drug release/absorption, the matrix/shell is expelled in the stool. The use of nondeformable products in patients with known stricture/narrowing of the GI tract has been associated with symptoms of obstruction. Use caution in patients with increased GI retention (eg, chronic constipation) as doxazosin exposure may be increased.

Other warning/precautions:

• Appropriate use: Extended release: Not indicated for use in women or for the treatment of hypertension.

Monitoring Parameters

Blood pressure routinely and for at least 6 hours after initial dose and with each dose increase (standing and sitting/supine); monitor patients with mild-to-moderate impairment for symptoms of hypotension.

Hypertension: The 2017 Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults (ACC/AHA [Whelton 2017]):

Confirmed hypertension and known CVD or 10-year ASCVD risk ≥10%: Target blood pressure <130/80 mm Hg is recommended

Confirmed hypertension without markers of increased ASCVD risk: Target blood pressure <130/80 mm Hg may be reasonable

Pregnancy Considerations

Doxazosin crosses the placenta (Versmissen 2016).

Chronic maternal hypertension may increase the risk of birth defects, low birth weight, preterm delivery, stillbirth, and neonatal death. Actual fetal/neonatal risks may be related to duration and severity of maternal hypertension. Untreated hypertension may also increase the risks of adverse maternal outcomes, including gestational diabetes, myocardial infarction, preeclampsia, stroke, and delivery complications (ACOG 203 2019).

Agents other than doxazosin are more commonly used to treat hypertension in pregnancy (ACOG 203 2019; ESC [Regitz-Zagrosek 2018]). Females with preexisting hypertension may continue their medication during pregnancy unless contraindications exist (ESC [Regitz-Zagrosek 2018]). Although rare, use of doxazosin for the treatment of hypertension due to a pheochromocytoma during pregnancy has been described; treatment was generally started after the first trimester (Lenders 2019; van der Weerd 2017).
