Overview of Ofuxal

Quick Facts Name Description
Active ingredient Alfuzosin hydrochloride
Form Extended-release tablet (oral)
Pharmacological class Alpha-1 Adrenergic Receptor Antagonist (Alpha-Blocker)
Common use Symptomatic relief for lower urinary tract issues in adult men
Origin Synthetic compound (quinazoline derivative)

Defining the Medicinal Entity: Alfuzosin

Ofuxal is a prescription-only pharmaceutical preparation whose active substance is Alfuzosin hydrochloride, a synthetic compound classified chemically as a quinazoline derivative. The medicine belongs to the major pharmacological classification known as the alpha-1 adrenergic receptor antagonist class, which is frequently termed an alpha-blocker. Alfuzosin provides targeted support for symptoms associated with lower urinary tract issues in adult men. This single-ingredient drug is intended for oral consumption, representing a focused, chemically precise therapeutic agent.

Composition and Pharmaceutical Form

The medicine is manufactured exclusively as an extended-release tablet, defined as an oral dosage form designed to control the rate of drug release over many hours. The tablet comprises the active ingredient, Alfuzosin hydrochloride, embedded within the necessary solid pharmaceutical excipients. The extended-release design is engineered to allow for a gradual, stable delivery of Alfuzosin into the system, a feature intended to maintain a more consistent therapeutic concentration than conventional forms.

General Purpose and Action of Alfuzosin

The overall purpose of Alfuzosin is functional: to relieve symptomatic discomfort in the lower urinary system by reducing muscle tone. Its classification as an alpha-blocker means it works by establishing a selective post-synaptic alpha-1 blockade, interrupting the signals that cause the smooth muscle tissue in structures like the bladder neck and prostate gland to tighten involuntarily. The primary therapeutic effect of this mechanism is the functional relaxation of these muscles, which results in a reduction of resistance and pressure on the urethra, thereby facilitating easier passage of fluid and providing symptomatic relief.

What side effects are possible with Ofuxal?

Possible Side Effects and Safety Information

The official safety information for Alfuzosin (Ofuxal) documents possible adverse reactions based on frequency and system-organ classification. The risk profile is primarily influenced by its function as an alpha-blocker, affecting the vascular and nervous systems.


Frequency and System Classification

Adverse reactions are formally categorized in regulatory documentation. Common reactions often observed in clinical trials include Dizziness, Headache, Fatigue (Asthenia), and Postural Hypotension (a drop in blood pressure upon standing). Uncommon documented effects include Syncope (fainting), Tachycardia (increased heart rate), Palpitations, and Rhinitis (stuffy nose). Gastrointestinal issues, such as nausea and abdominal pain, are also reported.


Serious Adverse Reactions

Regulatory sources explicitly define specific serious events that have been documented. These include Syncope, related to blood pressure effects, and Priapism, a painful, persistent erection that requires immediate medical attention. Intraoperative Floppy Iris Syndrome (IFIS), a complication during cataract or glaucoma surgery, has also been reported in patients taking this class of medication. Additionally, post-marketing surveillance has documented cases of Serious Hepatic Injury.


Safety Constraints and Special Populations

Official prescribing information establishes specific limitations for use. The medicine is Contraindicated in individuals with severe hepatic (liver) impairment and those using potent CYP3A4 inhibitors (which increase drug levels). Caution is required for patients with coronary artery disease, as the drug may cause or worsen angina. Time-related patterns show that reactions like postural hypotension may be more likely to occur shortly after the first dose or during dose escalation.

Overdose and Emergency Response

Overdose and When to Seek Urgent Medical Help

If an overdose of a medication like Ofuxal (Alfuzosin Hydrochloride) is suspected, immediate medical attention is required regardless of the presence of symptoms. Contact a poison control center or seek emergency services right away.

Officially Documented Overdose Presentations and Management

Overdose Manifestation Primary Required Emergency Action Special Considerations
The most prominent documented sign of overdosage is hypotension (low blood pressure). Cardiovascular support is of first importance to restore blood pressure and normalize heart rate. Dialysis may not be of benefit due to the high protein binding of the drug (82% to 90%).

Regulatory documents emphasize that the support of the cardiovascular system should begin without delay. Initial steps include keeping the affected individual in the supine position (lying on the back). If this measure is insufficient to stabilize blood pressure, the administration of intravenous fluids should be considered. Furthermore, if these initial measures are still inadequate, the use of vasopressors may be necessary.

Following stabilization, the official guidance requires that renal function should be monitored and supported as needed to manage the overall clinical picture. The prompt implementation of these measures is essential in an overdose situation.

Therapeutic Uses of Ofuxal

What Ofuxal Treats: Main Uses and Benefits

Ofuxal is an alpha-1 blocker medication primarily used to manage symptoms associated with certain urological conditions. Its active ingredient, alfuzosin, acts on specific receptors to help improve urinary flow and comfort.

Primary Indications

The medication is most commonly used for the following purposes:

  • Benign Prostatic Hyperplasia (BPH): Ofuxal is used to treat the symptoms of an enlarged prostate, a non-cancerous condition common in aging men. By relaxing the smooth muscles in the prostate and the neck of the bladder, it helps alleviate urinary difficulties.
  • Acute Urinary Retention (AUR): In some cases, it is used as an adjunctive therapy for patients experiencing a sudden inability to urinate. It may be administered alongside catheterization to increase the likelihood of successful voiding after the catheter is removed.

Key Benefits and Effects

By targeting the muscle tissues involved in urination, the medication provides several clinical benefits:

  • Improved Urinary Flow: By reducing the resistance at the bladder outlet, it helps the urine flow more freely and strongly.
  • Reduction of Lower Urinary Tract Symptoms (LUTS): It addresses common issues such as the frequent urge to urinate (especially at night), a weak or interrupted stream, and the sensation that the bladder is not completely empty.
  • Rapid Symptom Relief: Unlike some other prostate treatments that may take months to show results, the relaxing effect on smooth muscle typically begins to improve urinary symptoms shortly after starting the treatment.
  • Selective Action: The medication is designed to target receptors in the urinary tract more specifically, which helps maintain efficacy while minimizing effects on systemic blood pressure.

Eligibility and Restrictions for Use

Eligibility Profile: Official Regulatory Rules

Ofuxal (Alfuzosin hydrochloride) is officially indicated for use only in adult men to manage symptoms related to Benign Prostatic Hyperplasia (BPH). Its eligibility profile is strictly defined by regulatory authorities based on specific patient demographics, organ function, and concurrent medications.


Absolute Contraindications

Use of this medicine is prohibited in specific patient groups, as defined in the official labeling:

  • Severe Hepatic Impairment: The medicine is contraindicated in patients with moderate or severe liver impairment (Childs-Pugh B and C).
  • Hypersensitivity: Patients with known hypersensitivity to Alfuzosin or any component of the tablet.
  • Concurrent Medication Use: Contraindicated in patients concurrently taking other alpha-1 blockers or potent CYP3A4 inhibitors (such as certain antivirals or antifungals).
  • Orthostatic Hypotension: A history of orthostatic hypotension may be listed as a contraindication in some regulatory documents.

Restricted or Non-Recommended Use

  • Severe Renal Impairment: Use is not recommended in patients with severe kidney problems (creatinine clearance < 30 mL/min), as safety data are limited.
  • Cardiovascular Conditions: Caution is required for patients with a history of QT prolongation or those with coronary insufficiency. If angina worsens, use must be discontinued.
  • Age and Gender: The medicine is not indicated for use in women or the pediatric population (under 18 years) as the BPH indication is male-specific and efficacy in children is not established.

What should I know about interactions with other medicines?

Interactions with other medicines and products

The interaction profile for Alfuzosin hydrochloride is officially documented through specific pharmacokinetic and pharmacodynamic restrictions, as defined by regulatory authorities.

Formal Restrictions and Contraindications

Co-administration is formally contraindicated with certain substances due to the risk of severe interaction:

  • Potent CYP3A4 Inhibitors: Medicines such as Ketoconazole and Ritonavir are prohibited. These substances block the primary enzyme responsible for Alfuzosin metabolism, which is officially documented to significantly increase Alfuzosin exposure and blood levels.
  • Other Alpha-1 Adrenergic Antagonists: The use of other medicines belonging to the alpha-blocker class is prohibited due to the potential for severe additive effects, specifically a high risk of symptomatic hypotension.

Clinically Significant Interactions

The potential for pharmacodynamic interactions extends to other medications that affect blood pressure. The risk of hypotension is officially documented to increase when Alfuzosin is co-administered with antihypertensive drugs, nitrates, or Phosphodiesterase-5 (PDE5) inhibitors (e.g., Sildenafil). Moderate CYP3A4 inhibitors, such as Diltiazem, also increase Alfuzosin plasma concentrations.

Administration and Clearance Constraints

A critical constraint is the mandatory requirement to take the extended-release tablet with food. Administration in a fasted state is officially documented to reduce absorption by 50%. Furthermore, the medicine is contraindicated in patients with moderate or severe hepatic impairment because their reduced clearance leads to increased Alfuzosin blood levels.

Mechanism of Action

Targeting Alpha-1 Adrenergic Receptors to Block Sympathetic Signals

The core action of Alfuzosin is a competitive blockade of the post-synaptic alpha1-adrenoceptors, which are concentrated on smooth muscle tissue in the lower urinary tract . By occupying the receptor site, the drug prevents the endogenous neurotransmitter norepinephrine from initiating its signal, thus suppressing the sympathetic input that initiates muscle contraction.


Molecular Cascade and Smooth Muscle Relaxation

Blocking the alpha1-receptor interrupts the internal Gq protein signaling cascade, which normally triggers the release of intracellular calcium ions ( Ca^2+). The resulting suppression of Ca^2+ release leads directly to the relaxation of the smooth muscle tissue in the prostate and bladder neck.


Modulation of Dynamic Urethral Resistance

The resulting smooth muscle relaxation is characterized by functional uroselectivity and produces a key physiological change: a reduction of pressure and resistance at the bladder outlet. The mechanism's influence is restricted to the dynamic (muscle tone) component, as opposed to fixed physical volume.

Dosage and Administration Information

How Ofuxal is Used: Administration Guidelines

Ofuxal is formulated as a 10 mg extended-release tablet and is taken orally. The administration follows specific protocols to ensure consistent absorption of the active ingredient, Alfuzosin hydrochloride.


Dosing and Administration

Instruction Entity Administration Details
Route of Administration The medication is taken orally (swallowed by mouth).
Standard Dosing The recommended dosage is one 10 mg extended-release tablet per day.
Timing in Relation to Meals Must be taken immediately after the same meal each day. The absorption of Alfuzosin is 50% lower if taken in a fasting state.
Preparation Requirements The tablet must be swallowed whole with a sufficient amount of liquid.
Missed Dose Rules If a dose is missed, the patient should skip the missed dose and resume the schedule with the next dose. Do not take two tablets at the same time to compensate.

Procedural and Population Constraints

Special Procedural Conditions

The extended-release tablet must not be chewed, crushed, or split. Breaking the tablet compromises the controlled-release mechanism, which may lead to inappropriate absorption of the entire dose.

Population-Specific Rules

  • Pediatric Use: The medication is not indicated for use in the pediatric population (patients under 18 years of age).
  • Older Adults: No routine dose adjustment is required for geriatric patients (aged 65 years and over).
  • Hepatic Impairment: The 10 mg extended-release tablet is contraindicated for use in patients with moderate or severe liver impairment.

This regimen is structured for long-term daily use to provide continuous management of symptoms, and adherence to the fixed, once-daily dose taken with food is central to the prescribing protocol.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Ofuxal

Evidence for Use in Lower Urinary Tract Symptoms (LUTS) due to BPH

Research exploring Alfuzosin in studies for symptoms of an enlarged prostate has been conducted using several different study types. The core evidence stems from multiple randomized, controlled trials (RCTs). In these trials, adult males with moderate to severe LUTS due to Benign Prostatic Hyperplasia (BPH) were given either the study medicine or an inactive substitute called a placebo for a short duration, usually around three months.

In these studies, researchers monitored changes in subjective measures, such as the International Prostate Symptom Score (IPSS). The research also monitored objective measures, such as Peak Urinary Flow Rate (Qmax) and Post-Void Residual (PVR) urine volume. Short-term findings described patterns where patients receiving the medicine had different measurements in these symptom and flow scores compared to patterns observed in the placebo groups.

Evidence in Acute Urinary Retention (AUR) Settings

Research explored Alfuzosin in a specific, acute setting: the temporary inability to pass urine, known as Acute Urinary Retention (AUR), when it is related to BPH. This research involved conducting randomized trials on adult males immediately after they experienced their first episode of AUR and required a catheter. The trials were designed to examine outcomes describing episodic or acute symptom patterns. The main focus was monitoring the proportion of patients who achieved successful catheter-free voiding after the catheter was removed, compared to those receiving a placebo.

Long-Term Studies and Durability of Follow-up

To examine the long-term patterns related to symptoms and flow measures, researchers conducted open-label studies, often as extensions of the original short-term trials, using data from extended-duration observational studies that followed patients for periods extending up to three years or more. Some research also explored long-term BPH progression endpoints, such as the need for BPH-related surgery or the recurrence of AUR.

What is Still Uncertain About the Research

The highest quality comparative evidence (double-blind, placebo-controlled data) is primarily limited to short-term observation periods (around 3 months). Long-term effects are not fully established under those strict trial conditions. Comparative evidence is lacking for direct, head-to-head trials against all alternative alpha-blocker formulations currently available. The research does not predict whether an individual will respond similarly, as findings describe group patterns, not personal outcomes.
