What Type of Medicine is Fluconazol 1A Pharma?

Fluconazol 1A Pharma is a specific trade name for a medicine containing the active ingredient Fluconazole. This compound is classified as an antifungal agent belonging specifically to the triazole antifungal group. The medication is synthetic and functions as a systemic anti-infective, a classification that indicates its use is clinically recognized for targeting internal fungal infections. The product is a common generic equivalent manufactured by 1A Pharma GmbH, typically reserved as a prescription-only medicine, reflecting its potent systemic action.

Composition and General Purpose

Fluconazol 1A Pharma is a single active ingredient product commonly supplied in solid dosage forms for oral use, most frequently as a tablet or hard capsule. The general therapeutic purpose of the medicine is to clear fungal infections by interfering with the fungus's ability to maintain its cellular structure. Fluconazole acts as a potent sterol synthesis inhibitor. By selectively blocking the production of ergosterol, an essential component of the fungal cell membrane, the drug causes the fungal cell wall to become compromised. This fundamental action allows the medicine to actively combat and reduce the burden of fungal disease.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Fluconazole carries the risk of clinically significant interactions with numerous other medicinal products. These interactions are primarily based on the drug's activity as a strong inhibitor of Cytochrome P450 enzymes CYP2C9 and CYP2C19, and a moderate inhibitor of CYP3A4.

Contraindicated Combinations

The following drugs must not be used concomitantly due to the high risk of serious cardiac events, including prolonged QT interval and Torsade de Pointes:

  • Astemizole
  • Cisapride
  • Pimozide
  • Quinidine
  • Terfenadine (when Fluconazole dose is ge 400 mg/day)

Significant Pharmacokinetic Interactions

Co-administration with Fluconazole increases the systemic exposure (AUC/Cmax) of many medicines, necessitating close monitoring and potential dose adjustment:

  • Immunosuppressants: Increases levels of Cyclosporine, Tacrolimus, and Sirolimus.
  • Anticoagulants: Increases levels of Warfarin, raising the risk of bleeding.
  • Statins: Increases concentrations of statins metabolized by CYP3A4 or CYP2C9 (e.g., Simvastatin, Atorvastatin), increasing the risk of muscle toxicity (rhabdomyolysis).

Additionally, some medicines can alter Fluconazole levels; for example, Rifampicin significantly decreases Fluconazole concentration. No clinically significant impairment of Fluconazole absorption is documented when administered with food.

Mechanism of Action

Inhibition of Fungal Cell Membrane Synthesis

Fluconazole belongs to the triazole class, and its action involves the specific modulation of a key enzyme-mediated signaling pathway within the fungal cell. The mechanism focuses on disrupting the organism's structural integrity. Fluconazole engages mechanisms that regulate the production of ergosterol, an essential component of the fungal cell membrane. The drug modifies early molecular steps by binding to and inhibiting the fungal cytochrome P450 enzyme, lanosterol 14-alpha-demethylase (or CYP51).


Destabilization of Fungal Cell Structure

The inhibition of lanosterol 14-alpha-demethylase causes a mechanistic cascade resulting in the depletion of ergosterol and the accumulation of abnormal, methylated sterols within the fungal cell membrane. This alters pathway activity that controls membrane fluidity and permeability, ultimately leading to the loss of membrane integrity and disruption of fungal proliferation. This intracellular consequence represents the system-level physiological modulation that restricts the organism's ability to propagate.

Dosage and Administration Information

Official Administration Guidelines

Fluconazol 1A Pharma is taken by the oral route (capsule or suspension) and can be consumed with or without food. The dosage regimen is highly variable, determined by the prescribing physician, and may range from a single dose to once daily or once weekly administration. Treatment requires that the full prescribed course must be completed to prevent the recurrence of infection, even if symptoms appear to improve.

Procedural Requirements

  • Capsules: Swallow the capsule whole with a glass of water.
  • Oral Suspension (Liquid): The bottle must be shaken well before each use. The dose must be accurately measured using a proper oral dosing syringe or measuring spoon, not a household utensil, to ensure the correct volume is administered.
  • Timing: For daily regimens, it is advised to take the medicine at approximately the same time each day to maintain consistent drug levels.

Dosing Adjustments for Specific Populations

The required dose is modified for certain patients:

Patient Condition Initial Dose (if multi-dose) Subsequent Daily Dose
Creatinine Clearance >50 mL/min Full recommended dose 100% of recommended dose
Creatinine Clearance ≤50 mL/min Full recommended dose 50% of recommended dose
Hemodialysis Full recommended dose 100% of recommended dose after each dialysis session
  • Children: Doses for pediatric patients are calculated based on body weight (mg/kg). Neonates (first four weeks of life) have specific, extended-interval dosing schedules that must be followed.

Missed Dose Instructions

If a dose is missed, it should be taken as soon as remembered. However, if it is almost time for the next scheduled dose, the missed dose must be skipped, and the regular schedule continued. Do not take a double dose to compensate for the missed one.

Recent Clinical Evidence

Research evidence / Overview of studies for Fluconazol 1A Pharma


Evidence for Use in Systemic and Invasive Fungal Infections

The research on systemic infections, such as candidemia (infections that enter the bloodstream) and cryptococcal meningitis, was evaluated in Randomized Controlled Trials (RCTs) and controlled comparative studies. These studies were designed to measure high-level outcomes reflecting physiological strain or stress. Researchers monitored outcomes such as overall survival and whether the fungal organism was observed for clearance from the bloodstream or the spinal fluid.

For severe Candida infections, trials have explored how changes in patient status were measured when fluconazole was evaluated in comparison to other established antifungal treatments. For cryptococcal meningitis, research examines the role of fluconazole in the phases following an initial intensive treatment. Ongoing research is focused on better understanding its role in combination treatment regimens. Long-term effects for specific populations, such as outcomes related to daily functioning or activity level years after treatment, are not fully established.


Evidence for Use in Mucosal and Localized Fungal Infections

The evidence for localized conditions, such as oral, throat, and vaginal yeast infections (mucosal candidiasis), was evaluated in a large number of short-term RCTs, systematic reviews, and meta-analyses. Researchers studied the medicine for outcomes related to physical discomfort and outcomes linked to inflammatory or irritative states. Short-term trials reported how symptoms evolved in the observed populations, and findings describe patterns observed in the studies related to the resolution of visible signs of infection and clearance of the fungal organism.

What remains uncertain relates to the variability of outcomes due to emerging resistance in some fungal populations. Long-term follow-up durations were limited in many trials, meaning data for sustained clearance and recurrence prevention is less comprehensive than data for the initial response.


Research on Prophylaxis (The Attempt to Prevent the Onset) of Fungal Infections

Fluconazole was studied for prophylaxis (the attempt to prevent the onset) of invasive fungal infections. This research relied primarily on RCTs, including double-blind placebo-controlled designs, in specific high-risk groups, such as very low birth weight preterm neonates and adult patients undergoing intensive chemotherapy. Findings describe patterns observed in the studies, indicating associations with the incidence of invasive fungal infection in these cohorts. However, findings were mixed when assessing outcomes related to overall mortality, meaning data show patterns related to survival that were not consistent across all patient groups studied for prophylaxis.
