Description
Diamox SR (sustained release) is an oral pill made up of acetazolamide, a carbonic anhydrase inhibitor and anticonvulsant. Diamox SR is the same as Diamox, however the sustained release tablet (Diamox SR) allows for drug released over a sustained period of time but not at a constant rate. This medication can be bought as the brand choice Diamox SR in 250mg!
Diamox SR is a medication prescribed to prevent and reduce symptoms of altitude sickness. Altitude sickness occurs when you begin to feel negative health effects from rapid exposure to high elevations and low oxygen (generally above 10,000 feet/3,048 meters). Symptoms can include headaches, tiredness, nausea and dizziness. Diamox SR helps this condition by inhibiting the carbonic anhydrase enzyme which counteracts with a low level of carbon dioxide in the blood that results from rapid or deep breathing (called respiratory alkalosis) which occurs during ascent to altitude while also allowing the excretion of bicarbonate in the urine; reducing altitude sickness.
This medication can alternatively be prescribed with other medications to treat high pressure located in the eye, caused by glaucoma. Edema can be reduced in people with congestive heart failure and certain types of seizures can also be treated with Diamox SR. Diamox SR helps these conditions by blocking and reducing the activity of carbonic anhydrase in the body which causes a decrease in fluids.
