Posaconazole AHCL

Treatment should be initiated by a physician experienced in the management of fungal infections or in the supportive care of high-risk patients for which posaconazole is indicated as prophylaxis. Non-interchangeability between Posaconazole AHCL oral suspension and posaconazole tablets or posaconazole gastro-resistant powder and solvent for oral suspension.

Posaconazole oral suspension is indicated for the adult population (≥18 years old) only. The oral suspension is not to be used interchangeably with either the tablet or gastro-resistant powder and solvent for oral suspension due to the differences in frequency of dosing, administration with food and plasma drug concentration achieved.

Therefore, follow the specific dose recommendations for each formulation. Posology Posaconazole is also available as 100 mg gastro-resistant tablet, 300 mg concentrate for solution for infusion and 300 mg gastro-resistant powder and solvent for oral suspension.

Posaconazole tablets generally provide higher plasma drug exposures than posaconazole oral suspension under both fed and fasted conditions. Therefore, the tablets are the preferred formulation over the oral suspension to optimize plasma concentrations.

Recommended dose is shown in Table 1. Table 1. Recommended dose in adults according to indication. 2) Refractory invasive fungal infections (IFI)/patients with IFI intolerant to 1st line therapy 200 mg (5 mL) four times a day. Alternatively, patients who can tolerate food or a nutritional supplement may take 400 mg (10 mL) twice a day during or immediately following a meal or nutritional supplement.

Duration of therapy should be based on the severity of the underlying disease, recovery from immunosuppression, and clinical response. 5 mL) once a day for 13 days. Each dose of Posaconazole AHCL should be administered during or immediately after a meal, or a nutritional supplement in patients who cannot tolerate food to enhance the oral absorption and to ensure adequate exposure Prophylaxis of invasive fungal infections 200 mg (5 mL) three times a day.

Each dose of Posaconazole AHCL should be administered during or immediately after a meal, or a nutritional supplement in patients who cannot tolerate food to enhance the oral absorption and to ensure adequate exposure. The duration of therapy is based on recovery from neutropenia or immunosuppression.

Summary of the safety profile The safety of posaconazole oral suspension has been assessed in > 2,400 patients and healthy volunteers enrolled in clinical studies and from post-marketing experience. The most frequently reported serious related adverse reactions included nausea, vomiting, diarrhoea, pyrexia, and increased bilirubin.

Tabulated list of adverse reactions Within the organ system classes, adverse reactions are listed under headings of frequency using the following categories: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥ 1/10,000 to <1/1,000); very rare (<1/10,000); not known (cannot be estimated from the available data).

Hypersensitivity There is no information regarding cross-sensitivity between posaconazole and other azole antifungal agents. Caution should be used when prescribing posaconazole to patients with hypersensitivity to other azoles. g. mild to moderate elevations in ALT, AST, alkaline phosphatase, total bilirubin and/or clinical hepatitis) have been reported during treatment with posaconazole.

Elevated liver function tests were generally reversible on discontinuation of therapy and in some instances these tests normalised without interruption of therapy. Rarely, more severe hepatic reactions with fatal outcomes have been reported.

2). Monitoring of hepatic function Liver function tests should be evaluated at the start of and during the course of posaconazole therapy. Patients who develop abnormal liver function tests during posaconazole therapy must be routinely monitored for the development of more severe hepatic injury.

Patient management should include laboratory evaluation of hepatic function (particularly liver function tests and bilirubin). Discontinuation of posaconazole should be considered if clinical signs and symptoms are consistent with development of liver disease.

QTc prolongation Some azoles have been associated with prolongation of the QTc interval. 5). 3). Electrolyte disturbances, especially those involving potassium, magnesium or calcium levels, should be monitored and corrected as necessary before and during posaconazole therapy.

5). g. midazolam, triazolam, alprazolam) should only be considered if clearly necessary. 5). Vincristine toxicity Concomitant administration of azole antifungals, including posaconazole, with vincristine has been associated with neurotoxicity and other serious adverse reactions, including seizures, peripheral neuropathy, syndrome of inappropriate antidiuretic hormone secretion, and paralytic ileus.
