Interaction Details
Ulipristal Acetate 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.

Algin Overview
Algin is a type of polysaccharide that is extracted from brown algae and also made naturally by some types of bacteria. It is most commonly referred to as sodium alginate. It is used as a thickening agent, stabilizer, and emulsifier in a variety of products. In food, algin is commonly used as a gelling agent to create a variety of textures. In manufacturing, algin is used as a binding and disintegrating agent in tablets, and as a binding and demulcent in lozenges. It has been studied for potential health benefits, such as reducing cholesterol levels and improving digestive health.
Ulipristal Acetate Overview
-
Ulipristal is used to prevent pregnancy after unprotected sexual intercourse (sex without any method of birth control or with a birth control method that failed or was not used properly [e.g., a condom that slipped or broke or birth control pills that were not taken as scheduled]). Ulipristal should not be used to prevent pregnancy on a regular basis. This medication is to be used as an emergency contraceptive or backup in case regular birth control fails or is used incorrectly. Ulipristal is in a class of medications called progestins. It works by preventing or delaying the release of an egg from the ovary. It also may work by changing the lining of the uterus (womb) to prevent development of a pregnancy. Ulipristal may prevent pregnancy, but it will not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.
