Diovan Angiotensin Receptor Blocker GMP Valsartan White Crystalline Powder CAS 137862-53-4
Product Details:
Diovan Medicine Raw Material GMP Valsartan Treat Congestive Heart Failure CAS 137862-53-4
Description
Valsartan belong to non peptide, orally active angiotensin Ⅱ ( AT ) receptor antagonist. It is highly selective for Ⅰ type ( AT1 ) receptor, can be competitive antagonism to without any excitement. It can also be mediated by inhibition of AT1 receptor adrenal cells release aldehyde sterol, but for potassium caused by the release of valsartan no inhibition, it also suggests that valsartan for AT1 receptor selectivity.
The experiments of various types of hypertensive animal models showed that valsartan had a good hypotensive effect, which had no significant effect on cardiac systolic function and heart rate. Animals with normal blood pressure do not have a blood pressure lowering effect. The uptake was rapid and bioavailability was 23 %. The binding rate of plasma protein was 94% ~ 97%. About 70% of the excrement is excreted, and 30% of the renal excretion is in the original form. T1 over 2 beta is about 9 hours. It is not affected by the combination of food and food.
The blood pressure began to decline after 2 hours after taking a patient with high blood pressure, and the maximum blood pressure effect was reached between 4 and 6 hours. The hypotensive effect lasts for 24 hours. The maximal effect of blood pressure was decreased by 2 ~ 4 weeks after continuous use. It can be used in combination with hydrochlorothiazide, and the blood pressure can be enhanced.
Uses
Blood pressure medicine. Valsartan for angiotensin Ⅱ ( Ang Ⅱ) receptor antagonist, can selectively block Ang Ⅱ combined with AT1 receptor ( its specificity of AT1 receptor of antagonism effect about 20000 times greater than AT2 ), thus inhibiting vascular contraction and the release of aldosterone, antihypertensive effect.
Contraindications
The packaging for valsartan includes a warning stating the drug should not be used with the renin inhibitor aliskiren in people with diabetes mellitus. It also states the drug should not be used in people with kidney disease.
Valsartan falls in FDA pregnancy category D and includes a black box warning for fetal toxicity. Discontinuation of these agents is recommended immediately after detection of pregnancy and an alternative medication should be started. The US labeling makes no recommendation regarding continuation or discontinuation of valsartan for breast-feeding mothers. The Canadian labeling does not recommend use by nursing women.

PDE5 Inhibitor White Crystalline Powder Tadalafil 171596-29-5 For Male Erectile Dysfunction
Product Details:
PDE5 Inhibitor Medicine Raw Material Tadalafil For Male Erectile Dysfunction 171596-29-5
Description
Tadalafil ( INN ) is a PDE5 inhibitor marketed in pill form for treating erectile dysfunction ( ED ) under the name Cialis / siˈælᵻs / see - AL - iss, and under the name Adcirca / ædˈsɜːrkə / ad - SUR - kə for the treatment of pulmonary arterial hypertension. In October 2011 the U.S. Food and Drug Administration ( FDA ) approved Cialis for treating the signs and symptoms of benign prostatic hyperplasia ( BPH ) as well as a combination of BPH and erectile dysfunction when the conditions coincide.
It initially was developed by the biotechnology company ICOS, and then again developed and marketed worldwide by Lilly ICOS, LLC, the joint venture of ICOS Corporation and Eli Lilly and Company. Cialis tablets, in 2.5 mg, 5 mg, 10 mg, and 20 mg doses, are yellow, film - coated, and almond - shaped. The approved dose for pulmonary arterial hypertension is 40 mg ( two 20 mg tablets ) once daily.
Drug interactions
Since PDE5 inhibitors such as tadalafil may cause transiently low blood pressure ( hypotension ), alkyl nitrites ( poppers ) should not be taken for at least 48 hours after taking the last dose of tadalafil. Using poppers ( such as the sex drug amyl nitrite ) within this timeframe may increase the risk of life - threatening hypotension.
Since people who have taken tadalafil within the past 48 hours cannot take organic nitrates to relieve angina ( such as glyceryl trinitrate spray ), these patients should seek immediate medical attention if they experience anginal chest pain. In the event of a medical emergency, paramedics and medical personnel should be notified of any recent doses of tadalafil.
Tadalafil is metabolized predominantly by the hepatic CYP3A4 enzyme system. The presence of other drugs which induce this system can shorten tadalafil half - life and reduce serum levels, and hence efficacy, of the drug.

Valsartan White Crystalline Powder For Posterior Myocardial Infarction
Product Details:
Valsartan Medicine Raw Material for Treat Posterior Myocardial Infarction primary hypertension
Description
Valsartan is an angiotensin II receptor antagonist antihypertensive drugs, the drug is a make angiotensin Ⅱ type 1 ( AT1 ) receptor blockade, angiotensin Ⅱ plasma levels, stimulate non - sealing AT2 receptors, against the effect of AT1 receptor at the same time, so as to achieve to dilate blood vessels the effect of lowering blood pressure.
In the United States, valsartan is a drug used to treat hypertension, congestive heart failure and post - myocardial infarction.
Switzerland ciba - fine base company research and development production of the generation of valsartan in 1995 and 1996, respectively, to obtain a patent in the United States and Europe, and in July 1996 for the first time to market in Germany, then gradually in Europe, America, Japan. Valsartan has the characteristics of stable hypotension effect and small toxicity.
Medical uses
Valsartan is used to treat high blood pressure, congestive heart failure, and to reduce death for people with left ventricular dysfunction after having had a heart attack.
In people with type II diabetes and high blood pressure or albumin in the urine, valsartan is used to slow the worsening and the development end-stage renal disease.
Mechanism of action
Valsartan blocks the actions of angiotensin II, which include constricting blood vessels and activating aldosterone, to reduce blood pressure. The drug binds to angiotensin type I receptors ( AT1 ), working as an antagonist. This mechanism of action is different than the ACE inhibitor drugs, which block the conversion of angiotensin I to angiotensin II.
Since valsartan acts at the receptor, it can provide more complete angiotensin II antagonism since angiotensin II is generated by other enzymes as well as ACE. Also, valsartan does not affect the metabolism of bradykinin like ACE inhibitors do.
