Spotlight on Posaconazole: A Leading Antifungal Medication


Posaconazole CAS No:171228-49-2

Posaconazole is a type of oral triazole antifungal API that has shown a high rate of efficacy for a number of fungal conditions without the risk of severe side effects. While many antifungal medications have ostensibly similar jobs, each one has their own limitations and patient disadvantages. Posaconazole was developed as an alternative on the market to help immune-compromised patients get the relief they need without the risk.

Inhibiting Fungus Growth

Like many fungal medications, Posaconazole actively interferes with the ergosterol of the fungus, making it harder for the fungus to multiply. However, it takes a slightly different approach by working against the cytochrome P-450 enzyme. By blocking this enzyme, the fungus either won’t be able to grow or it will expedite fungal cell death. It’s similar in chemical makeup to Itraconazole, but it replaces the fluorine in the phenyl ring with chlorine instead. This switch makes Posaconazole more powerful and flexible when it comes to handling different strains and strengths of common fungi. Posaconazole is processed through the liver and can take up to five hours to absorb into the body.

How It’s Used

Posaconazole is generally prescribed to immunocompromised patients with fungal conditions. It was successfully tested against a broad spectrum of common yeasts and fungi, such as Aspergillus and Mucor. Posaconazole has shown particular promise to treat the zygomycetes and Fusarium species of fungus. As fungus continues to mutate to adapt to new medications, Posaconazole may be an effective alternative where other methods fail and can be used across the board for mild and deadly diseases alike. It can just as easily be prescribed to someone with a mild yeast infection, as a patient diagnosed with the deadly Chagas Disease.

The Big Picture

The number of immunocompromised individuals around the world only continues to increase as life expectancy does the same. Posaconazole was developed to be a safe and effective alternative to harsher medications that are currently on the market. For example, Amphotericin B is effective at killing off infections, but the strength of the actual chemicals also inspired severe reactions such as high fevers or GI disruptions in certain immunocompromised patients. When it comes to efficacy rates for certain strains, Posaconazole may fare better in the long-term than other fungal inhibitors. For example, after 14 days of clinical trials for patients with Oropharyngeal Candidiasis, Fluconazole had a slight edge over Posaconazole (92.5% vs. 91.7%.) But after a full four weeks had passed, the success rates shifted to favor Posaconazole at 68.5% vs. 61.8%.

Easier on the Body

Posaconazole is also easier for the body to handle, and existing evidence suggests there are no adverse reactions to accidentally taking too much of drug. In clinical trials, participants on the higher doses had roughly similar experiences to those on the lower doses. When one person mistakenly took 2,400 milligrams of Posaconazole a day for three days (which was 800 milligrams higher than the highest dose in the trial), they found that the participant’s health remained unharmed. And while it’s true that Posaconazole will clash with other types of medications, it also doesn’t have nearly as many limitations as its cousin Itraconazole.
