Age, weight, and severity of the infection are important factors in determining the proper dosage. The usual dosage is 30 to 50 mg/kg/day, in equally divided doses. For more severe infections this dosage may be doubled but should not exceed 4 g per day.

In the treatment of streptococcal infections of the upper respiratory tract (e.g., tonsillitis or pharyngitis), the therapeutic dosage of Abomacetin should be administered for at least ten days.

Abomacetin interactions

Abomacetin use in patients who are receiving high doses of theophylline may be associated with an increase in serum theophylline levels (Abomacetin ethylsuccinate) and potential theophylline toxicity. In case of theophylline toxicity and/or elevated serum theophylline levels, (Abomacetin ethylsuccinate) the dose of theophylline should be reduced while the patient is receiving concomitant Abomacetin therapy.

Hypotension, bradyarrhythmias, and lactic acidosis have been observed in patients receiving concurrent verapamil, belonging to the calcium channel blockers drug class.

Concomitant administration of Abomacetin and digoxin has been reported to result in elevated digoxin serum levels. (Abomacetin ethylsuccinate)

There have been reports of increased anticoagulant effects when Abomacetin and oral anticoagulants were used concomitantly. Increased anticoagulation effects due to interactions of Abomacetin with various oral anticoagulants may be more pronounced in the elderly.

Abomacetin is a substrate and inhibitor of the 3A isoform subfamily of the cytochrome p450 enzyme system (CYP3A). Coadministration of Abomacetin and a drug primarily metabolized tions. Interactions with other drugs metabolized by the CYP3A isoform are also possible. The following CYP3A based drug interactions have been observed with Abomacetin products in post-marketing experience:

Ergotamine/dihydroergotamine

Concurrent use of Abomacetin and ergotamine or dihydroergotamine has been associated in some patients with acute ergot toxicity characterized by severe peripheral vasospasm and dysesthesia.

Triazolobenzodiazepines (such as triazolam and alprazolam) and related benzodiazepines

Abomacetin has been reported to decrease the clearance of triazolam and midazolam, and thus, may increase the pharmacologic effect of these benzodiazepines.

HMG-CoA Reductase Inhibitors

Abomacetin has been reported to increase concentrations of HMG-CoA reductase inhibitors (e.g., lovastatin and simvastatin). Rare reports of rhabdomyolysis have been reported in patients taking these drugs concomitantly.

Sildenafil (Viagra)

Abomacetin has been reported to increase the systemic exposure (AUC) of sildenafil. Reduction of sildenafil dosage should be considered.

There have been spontaneous or published reports of CYP3A based interactions of Abomacetin with cyclosporine, carbamazepine, tacrolimus, alfentanil, disopyramide, rifabutin, quinidine, methylprednisolone, cilostazol, vinblastine, and bromocriptine.

Concomitant administration of Abomacetin with cisapride, pimozide, astemizole, or terfenadine is contraindicated.

In addition, there have been reports of interactions of Abomacetin with drugs not thought to be metabolized by CYP3A, including hexobarbital, phenytoin, and valproate.

Abomacetin has been reported to significantly alter the metabolism of the nonsedating antihistamines terfenadine and astemizole when taken concomitantly. Rare cases of serious cardiovascular adverse events, including electrocardiographic QT/QT interval prolongation, cardiac arrest, torsades de pointes, and other ventricular arrhythmias have been observed. In addition, deaths have been reported rarely with concomitant administration of terfenadine and Abomacetin.

There have been post-marketing reports of drug interactions when Abomacetin is co-administered with cisapride, resulting in QT prolongation, cardiac arrhythmias, ventricular tachycardia, ventricular fibrillation, and torsades de pointes, most likely due to inhibition of hepatic metabolism of cisapride by Abomacetin. Fatalities have been reported.

Drug/Laboratory Test Interactions

Abomacetin interferes with the fluorometric determination of urinary catecholamines.
