triamcinolone moxifloxacin

Applies to: moxifloxacin / triamcinolone and moxifloxacin / triamcinolone

MONITOR CLOSELY: Concomitant administration of corticosteroids may potentiate the risk of tendinitis and tendon rupture associated with fluoroquinolone treatment. The mechanism is unknown. Tendinitis and tendon rupture have most frequently involved the Achilles tendon, although cases involving the rotator cuff (the shoulder), the hand, the biceps, and the thumb have also been reported. Some have required surgical repair or resulted in prolonged disability. Tendon rupture can occur during or up to several months after completion of fluoroquinolone therapy.

MANAGEMENT: Caution is recommended if fluoroquinolones are prescribed in combination with corticosteroids, particularly in patients with other concomitant risk factors (e.g., age over 60 years; recipient of kidney, heart, and/or lung transplant). Patients should be advised to stop taking the fluoroquinolone, avoid exercise and use of the affected area, and promptly contact their physician if they experience pain, swelling, or inflammation of a tendon. In general, fluoroquinolones should only be used to treat conditions that are proven or strongly suspected to be caused by bacteria and only if the benefits outweigh the risks.

cholestyramine triamcinolone

Applies to: cholestyramine and moxifloxacin / triamcinolone

ADJUST DOSING INTERVAL: Concurrent administration of bile acid sequestrants may delay and/or decrease the absorption of oral corticosteroids. Bile acid sequestrants can bind certain drugs in the intestine to form an insoluble complex that is excreted in the feces. Reduced bioavailability of hydrocortisone has been reported during concomitant administration with cholestyramine and colestipol. It is not known whether the interaction occurs with other bile acid binding resins such as colesevelam or with corticosteroids other than hydrocortisone, but the possibility should be considered.

MANAGEMENT: Oral corticosteroids should be administered at least 1 hour before or 4 to 6 hours after a cholestyramine or colestipol dose, and at least 4 hours before a colesevelam dose.

cholestyramine food

Applies to: cholestyramine

ADJUST DOSING INTERVAL: Bile acid sequestrants and the phosphate binder, sevelamer, can decrease the absorption of fat-soluble vitamins A, D, E, and K. By binding bile acids, these agents may interfere with normal fat digestion and absorption, thereby preventing the absorption of fat-soluble vitamins. When 8 grams of cholestyramine was administered simultaneously with a normal meal containing 250,000 units of vitamin A acetate in four healthy young adult subjects, plasma vitamin A levels were significantly reduced during a 9-hour postprandial period compared to the values obtained with the control meal. Coadministration with 4 grams of cholestyramine had no significant effect. In a crossover study involving healthy subjects, coadministration of sevelamer with calcitriol resulted in a significant reduction in bioavailability for calcitriol (calcitriol with sevelamer vs calcitriol alone: AUC 137 pg*h/mL vs 318 pg*h/mL and Cmax 40.1 pg/mL vs 49.7 pg/mL, respectively). Chronic use of bile acid sequestrants has been rarely associated with an increased bleeding tendency due to hypoprothrombinemia resulting from vitamin K deficiency. Isolated cases of Vitamin A (including one case of night blindness) and D deficiencies have also been reported with chronic cholestyramine therapy.

MANAGEMENT: When bile acid sequestrants are given for prolonged periods, some manufacturers recommend that concomitant supplementation with water-miscible or parenteral forms of fat-soluble vitamins be considered. If oral vitamin supplements are used with cholestyramine or colestipol, advise patients to take them at least 1 hour before or 4 to 6 hours after the bile acid sequestrant to minimize the potential impact on their absorption. No recommendations are available for sevelamer, but it may be advisable to follow the same precautions.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
