Interaction Details
Conjugated Estrogens is classified as belonging to the following category: Oral Drugs
Agar forms a thick gel, which may disrupt the absorption of nutrients and medications. Animal research suggests that consuming a diet consisting of 5% to 10% agar alters the absorption of nutrients from the diet. In one study, consuming a diet composed of 10% agar reduced the absorption of all evaluated minerals. Theoretically, agar may also impair the absorption of oral drugs.

Agar Overview
Agar is a type of polysaccharide that is extracted from red algae. It is used as a gelling agent in food, pharmaceuticals, and other products. In cooking, agar is commonly used to make jellies, puddings, and other desserts. It is also used in scientific laboratories as a solid growth medium for microorganisms (i.e., an agar petri dish). Agar is a vegetarian alternative to gelatin, and is a food rich in certain minerals, vitamins, and dietary fiber.
Conjugated Estrogens Overview
-
The estradiol cypionate and estradiol valerate forms of estrogen injection are used to treat hot flushes (hot flashes; sudden strong feelings of heat and sweating) and/or vaginal dryness, itching, and burning in women who are experiencing menopause (change of life; the end of monthly menstrual periods). However, women who need a medication only to treat vaginal dryness, itching, or burning should consider a different treatment. These forms of estrogen injection are also sometimes used to treat the symptoms of low estrogen in young women who do not produce enough estrogen naturally. The estradiol valerate form of estrogen injection is also sometimes used to relieve the symptoms of certain types of prostate (a male reproductive organ) cancer. The conjugated estrogens form of estrogen injection is used to treat abnormal vaginal bleeding that a doctor has decided is caused only by a problem with the amounts of certain hormones in the body. Estrogen injection is in a class of medications called hormones. It works by replacing estrogen that is normally produced by the body.
