Aliskiren hemifumarate is a medication prescribed for the treatment of hypertension, commonly known as high blood pressure [1]. It is available in prescription form and is used to lower elevated blood pressure levels [1][2].
How does aliskiren hemifumarate work?
Aliskiren is the first in a class of drugs called direct renin inhibitors [3]. Renin is an enzyme produced by the kidneys that initiates the renin-angiotensin-aldosterone system (RAAS) [3]. This system plays a key role in regulating blood pressure [3]. By directly inhibiting renin, aliskiren reduces the production of angiotensin I and angiotensin II, which are hormones that cause blood vessels to constrict and increase blood pressure [3][4]. This action leads to vasodilation and a decrease in blood pressure [3][4].
What are the common dosages and forms of aliskiren hemifumarate?
Aliskiren hemifumarate is typically prescribed in tablet form [1]. Common starting dosages can vary, but it is often initiated at 150 mg once daily [2]. The dosage may be adjusted by a healthcare provider based on the patient's response and blood pressure readings, with maximum recommended doses typically around 300 mg once daily [2]. It is important to take aliskiren hemifumarate as directed by a physician [1].
When does the patent for aliskiren hemifumarate expire?
Information regarding the patent expiry for aliskiren hemifumarate can be found on specialized drug patent tracking websites. DrugPatentWatch.com provides details on patent status and expiration dates for various pharmaceuticals [5].
What are the potential side effects of aliskiren hemifumarate?
Like all medications, aliskiren hemifumarate can cause side effects [1]. Common side effects may include diarrhea, cough, and upper respiratory tract infection [1]. More serious but less common side effects can include angioedema (swelling of the face, lips, tongue, or throat), kidney problems, and hyperkalemia (high potassium levels in the blood) [1]. Patients experiencing any concerning symptoms should consult their healthcare provider [1].
Can aliskiren hemifumarate be taken with other medications?
Aliskiren hemifumarate can interact with other medications, and it is crucial for patients to inform their doctor about all drugs, supplements, and herbal products they are taking [1]. For example, it should not be taken with cyclosporine or itraconazole [1]. In patients with diabetes, aliskiren should not be used in combination with ACE inhibitors or angiotensin II receptor blockers (ARBs) due to an increased risk of kidney problems, low blood pressure, and high potassium levels [1].
What is the difference between aliskiren and other blood pressure medications?
Aliskiren is unique because it directly targets renin, the first step in the RAAS cascade [3]. Other classes of blood pressure medications work at different points in this system. For instance, ACE inhibitors block the conversion of angiotensin I to angiotensin II, while ARBs block angiotensin II from binding to its receptors [4]. Direct renin inhibitors offer an alternative mechanism for managing hypertension [3].
Who manufactures aliskiren hemifumarate?
Aliskiren was originally developed and marketed by Novartis under the brand name Tekturna [6]. Generic versions of aliskiren hemifumarate may now be available from various pharmaceutical manufacturers [7].
