Interaction Details
Isoniazid, Pyrazinamide, Rifampin is classified as belonging to the following category: Oral Drugs
Theoretically, algin can alter the absorption of oral drugs. Laboratory research shows that algin, when consumed as part of the diet or used as a thickening agent in infant formula, reduces the absorption of certain minerals. Also, algin has been used as a tablet binder and disintegrant to enhance drug bioavailability. To avoid changes in absorption, take algin 30-60 minutes after oral medications.
