- cabotegravir
- Galzin (zinc acetate)
Interactions between your drugs
zinc acetate cabotegravir
Applies to: Galzin (zinc acetate) and cabotegravir
ADJUST DOSING INTERVAL: Coadministration with antacids, mineral supplements, or other medications containing polyvalent cations such as magnesium, aluminum, calcium, and iron may decrease the bioavailability of oral cabotegravir. The proposed mechanism involves chelation of cabotegravir by polyvalent cations, forming a complex that is poorly absorbed from the gastrointestinal tract. The interaction has not been studied with cabotegravir, but has been reported with other integrase strand transfer inhibitors (INSTIs).
MANAGEMENT: To minimize the risk of reduced viral susceptibility and resistance development associated with subtherapeutic levels of cabotegravir, medications containing polyvalent cations such as antacids and mineral supplements should be administered at least 2 hours before or 4 hours after the oral cabotegravir dose.

Drug and food interactions
zinc acetate food
Applies to: Galzin (zinc acetate)
ADJUST DOSING INTERVAL: The presence of certain foods (e.g., bread, bran, hard boiled eggs, coffee, and milk) may significantly delay the absorption of zinc acetate. Fibres, phytates, and other substances in food prevent zinc from entering intestinal cells by binding with it. Protein does not appear to interfere with its absorption.
MANAGEMENT: Zinc acetate should preferably be taken on an empty stomach, at least one hour before or two to three hours after meals. It may be taken with small amounts of protein such as meat.
