Overview of Fluconazol Azoflune

Property Description
Active ingredient Fluconazole
Form Oral tablet, suspension, or intravenous solution
Pharmacological class Triazole antifungal
Common use Systemic and mucosal fungal/yeast infections
Rx Status (US/Global) Prescription only (Rx) for systemic use

Fluconazole is the international non-proprietary name (INN) for a synthetic, broad-spectrum antifungal medication. It belongs to the class of drugs known as triazole antifungals, which are effective against various fungal and yeast infections, particularly those caused by the Candida species.

While Fluconazole is the active ingredient, Azoflune is a specific brand name under which it is marketed in certain regions. The drug is highly valued in clinical settings due to its unique pharmacokinetic profile; it is well-absorbed orally and achieves good penetration into various bodily tissues and fluids, including the central nervous system. This effective distribution is clinically recognized for making it a vital option for treating serious, systemic infections, such as cryptococcal meningitis.

Fluconazole's high effectiveness and reliability have led to its inclusion in the World Health Organization's List of Essential Medicines. The original formulation received approval in 1990, establishing its long history of clinical use and supporting its current status as a widely prescribed medication.

What side effects are possible with Fluconazol Azoflune?

Possible Side Effects and Safety Information

The safety profile of fluconazole, the active ingredient in Fluconazol Azoflune, is formally detailed in regulatory documents by global health authorities. Adverse reactions are classified by frequency and grouped according to the body system affected.


Frequency-Classified Adverse Reactions

Adverse reactions are most commonly reported in the Gastrointestinal Disorders and Nervous System Disorders categories.

Classification Examples of Officially Documented Effects
Common (Affecting 1 in 10 to 1 in 100) Headache, nausea, vomiting, diarrhea, abdominal pain, rash, and elevation of liver enzymes (ALT/AST).
Uncommon Insomnia, dizziness, somnolence, vertigo, dry mouth, jaundice, pruritus, and urticaria.
Rare Anaphylaxis, severe blood disorders (e.g., agranulocytosis), serious skin reactions (Stevens-Johnson syndrome, Toxic Epidermal Necrolysis), and cardiac arrhythmias.

Serious Adverse Reactions and Restrictions

Regulatory labeling highlights specific rare but clinically significant adverse reactions. These include Hepatic Failure and serious Cardiac Arrhythmias (Prolongation of the QT interval and Torsade de Pointes).

Population Safety Notes: Specific safety considerations exist for certain groups. Caution is advised for patients with existing Hepatic Impairment. In cases of Renal Impairment, monitoring is required due to altered drug clearance. Additionally, the drug is contraindicated in individuals with a known hypersensitivity to fluconazole or co-administered with specific medications (e.g., cisapride, pimozide) that pose a risk for cardiac events.

Time-Related Patterns: Fluconazole-associated hepatotoxicity is generally reported as reversible upon discontinuation of the medication. The development of a rash, particularly in certain patient populations, requires close regulatory monitoring for progression to a severe cutaneous event.

Overdose and Emergency Response

Overdose and When to Seek Help

The official regulatory documentation for Fluconazol Azoflune addresses the profile of a potential overdose. A key clinical manifestation reported in cases of overdose has been severe neurobehavioral changes, including hallucination and paranoid behavior. The appearance of these specific symptoms should be considered an indication for immediate emergency medical evaluation.

In the event of a suspected overdose, contact emergency medical services immediately. The management of overdose is symptomatic and supportive, based on the severity of the patient's condition as assessed by a healthcare professional.

Since the substance is primarily excreted in the urine, procedures may be considered to accelerate its clearance from the body. Regulatory information notes that a three-hour session of hemodialysis is known to reduce the substance's plasma concentration by approximately 50%. The use of procedures such as gastric lavage and other supportive measures may be instituted, as determined by a healthcare provider based on the patient's clinical state and the time since ingestion.

If an overdose of Fluconazol Azoflune is suspected, urgent medical attention is required. Do not wait for symptoms to worsen; immediate action allows healthcare professionals to institute critical supportive and procedural management promptly.

What should I know about interactions with other medicines?

Interactions with other medicines and products

The interaction profile for Fluconazole (Azoflune) is strictly based on data from official government regulatory documents, describing documented interaction patterns and restrictions.

Detail Official Regulatory Documentation Statement
Medicinal product categories with documented interactions Anticoagulants, Immunosuppressants, HMG-CoA Reductase Inhibitors, Antiarrhythmics, Antihistamines, Diuretics.
Specific interacting medicines (if explicitly listed) Astemizole, Cisapride, Pimozide, Quinidine, Erythromycin, Terfenadine, Warfarin, Celecoxib, Cyclosporine, Fentanyl, Amiodarone, Rifampicin, Hydrochlorothiazide.
Mechanistic basis of interactions Pharmacokinetic: Inhibition of metabolic enzymes (CYP2C9, CYP3A4) leading to increased plasma levels of co-administered drugs; Pharmacodynamic: Additive effects increasing the risk of QT interval prolongation.
Timing-based interaction rules (if applicable) Fluconazole absorption is not affected by food or antacids; administration may be taken without regard to meals.
Population-specific interaction notes Elimination is markedly affected by reduced renal function. Pharmacokinetic parameters are generally higher in the elderly (≥ 65 years).

Official Interaction Statements

  • Co-administration with agents such as Astemizole, Cisapride, and Pimozide is formally prohibited due to the documented risk of cardiotoxicity.
  • Fluconazole significantly increases the exposure of medicines including Warfarin (raising Prothrombin Time) and Cyclosporine due to inhibited metabolic clearance.
  • Rifampicin is documented to decrease Fluconazole exposure by 25% (AUC). Conversely, Hydrochlorothiazide is documented to increase Fluconazole plasma levels by approximately 40%.
  • The contraindication with Terfenadine is constrained by the Fluconazole dose: prohibited only at multiple doses of ≥ 400 mg/day.

Connection to the overall interaction profile:

Official regulatory documents define Fluconazole's interaction structure primarily through its documented inhibition of key metabolic enzymes, resulting in a strict list of prohibited combinations and required management for numerous co-administered drugs. The profile also clearly notes the absence of pharmacokinetic interactions with meals, removing administration timing as a constraint in those contexts.

Mechanism of Action

Fluconazole, the active component in Azoflune, exerts its effect through selective biochemical disruption of the fungal cell structure, leading to compromised cell membrane function. The mechanism is highly selective, focusing on pathways unique to the pathogen.

Targeting the Fungal Sterol Synthesis Enzyme

The drug's action initiates at the molecular level by selectively and non-covalently binding to and inhibiting lanosterol 14-alpha demethylase (14alpha-demethylase), a critical enzyme in the fungal Cytochrome P450 system. This engagement is the initial molecular step that interrupts the ergosterol biosynthesis pathway, which is critical for the pathogen's metabolic and structural integrity.

Destabilization of the Fungal Cell Membrane

By blocking the enzyme, the fungal cell cannot produce ergosterol, the fundamental membrane component, while simultaneously accumulating toxic precursors like 14-alpha methyl sterols. This dual defect severely compromises the fungal cell membrane's structure and permeability, resulting in a fungistatic effect—inhibition of growth and replication.

Mechanisms Limiting Pharmacodynamic Efficacy

The mechanism's full potential can be constrained by fungal counter-responses, notably mutations in the ERG11 gene that reduce drug binding to the target enzyme, or the overexpression of efflux pumps which actively transport the drug out of the cell. These physiological adaptations prevent Fluconazole from achieving the necessary concentration to maintain consistent enzyme inhibition.

Dosage and Administration Information

Fluconazole Azoflune is administered either orally as a tablet, capsule, or liquid suspension, or via intravenous (IV) infusion. The official administration protocol establishes that the oral and intravenous forms are considered pharmacokinetically equivalent, permitting patients to transition between the two routes at the same daily dosage.


Dosing Regimens and Schedule

The standard approach to use often involves a loading dose on the first day of therapy, which is typically double the subsequent daily amount (e.g., 400 mg or 800 mg). Following the initial day, the medication is generally taken as a maintenance dose once daily. For certain acute, localized conditions, administration may consist of a single oral dose of 150 mg. The maximum dose is generally 400 mg daily, though up to 800 mg may be used for severe conditions.


Administration Conditions and Adjustments

The timing of the oral dose is not dependent on food intake; tablets, capsules, and the suspension may be taken with or without a meal. When using the oral suspension, the liquid must be shaken well before use and measured precisely with a calibrated device. The intravenous solution requires slow infusion, typically not exceeding 200 mg per hour. Dosing requires adjustment for specific populations: in adults with renal impairment, the dose must be reduced according to measured creatinine clearance, and pediatric dosing is calculated based on body weight in milligrams per kilogram (mg/kg). The duration of use is scenario-dependent, ranging from a single dose to long-term maintenance lasting many months.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Fluconazol Azoflune


Evidence for use in Systemic and Invasive Fungal Infections

Research explored the use of this medicine in conditions characterized by systemic or functional imbalance, such as severe, deep-seated infections like candidemia. The evidence includes Randomized Controlled Trials (RCTs), meta-analyses, and comparative studies. These studies monitored outcomes related to systemic or functional imbalance, including all-cause mortality rates, microbiological endpoints, and the measurement of changes in clinical signs observed in patients.

The research examined diverse populations, including critically ill surgical patients, non-neutropenic patients, and certain pediatric populations. Findings describe patterns observed in these studies, including the measured rates of fungal clearance and the proportion of patients reporting changes in clinical signs during the observed time intervals. However, data show patterns related to all-cause mortality that were mixed across different subgroups.


Evidence for use in Mucosal and Localized Fungal Infections

The medicine was studied for its use in conditions associated with acute or disruptive episodes, such as localized infections, including oral, esophageal, and vulvovaginal candidiasis. Short-term clinical trials and comparative studies were conducted during periods of increased symptom activity. Research examined outcomes related to physical discomfort, such as the measurement of changes in local symptoms like itching and soreness, alongside microbiological clearance.

Findings describe patterns related to the recurrence rate of infection, particularly in patient groups with ongoing immunosuppression. Research highlights changes measured during the study period, but the overall duration and stability of the observed response in immunocompetent patients following a single course of therapy are not broadly characterized in all study designs.


Evidence for use in Infection Prevention (Prophylaxis)

The medicine was evaluated in studies focusing on episodes where symptoms become more noticeable, specifically for its role in prophylaxis against fungal infections in high-risk settings. This research primarily involved Randomized, Placebo-Controlled Trials (RCTs), where studies monitored outcomes such as the incidence of invasive fungal infections and all-cause mortality. Findings related to all-cause mortality were observed to be heterogeneous across study designs and patient groups. Long-term effects on the overall microbial balance following a course of prevention are not fully established.
