Decreased clearance w/ ketoconazole & troleandomycin. Convulsions w/ cyclosporin.
Camelon 4 Decreased hepatic clearance & increased plasma conc w/ CYP3A4 inhibitors eg, antibacterial (INH), grapefruit juice, Ca antagonist (mibefradil), histamine H
2 receptor antagonist (cimetidine), antiemetic (aprepitant, fosaprepitant), antifungal (itraconazole), Ca channel blocker (diltiazem), OCs (ethinylestradiol/norethindrone), immunosuppressants (ciclosporin, cyclophosphamide, tacrolimus), macrolide antibacterial (clarithromycin, erythromycin), antivirals (HIV-PIs). Increased hepatic clearance & decreased plasma conc w/ CYP3A4 inducers eg, antitubercular antibiotic (rifampin, rifabutin), anticonvulsants (phenobarb, phenytoin, primidone, carbamazepine). May affect hepatic clearance w/ another CYP3A4 substrates eg, immunosuppressant (cyclophosphamide, tacrolimus). Potentially increased acetylation rate & clearance of INH. May reduce the effects of anticholinesterases in myasthenia gravis. May increase blood glucose conc of antidiabetic agents. May increase plasma conc w/ PIs (eg, indinavir, ritonavir). May induce metabolism of HIV-PIs. May exacerbate endocrine changes w/ aminoglutethimide-induced adrenal suppression. Increased incidence of GI bleeding & ulceration w/ NSAIDs. Decreased salicylate serum levels w/ high-dose aspirin. Acute myopathy w/ anticholinergics (eg, neuromuscular blocking drugs). Antagonism of the neuromuscular blocking effects of pancuronium & vecuronium. Enhanced efficacy of coumarin anticoagulants. Increased risk of hypokalemia w/ K-depleting agents (eg, diuretics), amphotericin B, xanthines, or β
2 agonists.
Camelon 8 May potentiate/increase glycoside effect w/ cardiac glycosides. May potentiate/increase K-depleting effect w/ diuretics. Reduced hypoglycaemic effect of antidiabetic agents & anticoagulant effect of coumarin derivatives. Reduced corticosteroid effect w/ rifampicin, phenytoin or barbiturates. May potentiate/increase clearance of chronic high-dose acetosal.
