Moexipril an angiotensin converting enzyme inhibitor (ACE inhibitor) used for the treatment of hypertension and congestive heart failure. Moexipril can be administered alone or with other antihypertensives or diuretics.It works by inhibiting the conversion of angiotensin I to angiotensin II.It was patented in 1980 and approved for medical use in 1995. Moexipril is available from Schwarz Pharma under the trade name Univasc. Side effects
Moexipril is generally well tolerated in elderly patients with hypertension. Hypotension, dizziness, increased cough, diarrhea, flu syndrome, fatigue, and flushing have been found to affect less than 6% of patients who were prescribed moexipril. Mechanism of action
As an ACE inhibitor, moexipril causes a decrease in ACE. This blocks the conversion of angiotensin I to angiotensin II. Blockage of angiotensin II limits hypertension within the vasculature. Additionally, moexipril has been found to possess cardioprotective properties. Rats given moexipril one week prior to induction of myocardial infarction, displayed decreased infarct size. The cardioprotective effects of ACE inhibitors are mediated through a combination of angiotensin II inhibition and bradykinin proliferation. Increased levels of bradykinin stimulate in the production of prostaglandin E2 and nitric oxide, which cause vasodilation and continue to exert antiproliferative effects. Inhibition of angiotensin II by moexipril decreases remodeling effects on the cardiovascular system. Indirectly, angiotensin II stimulates of the production of endothelin 1 and 3 (ET1, ET3) and the transforming growth factor beta-1 (TGF-β1), all of which have tissue proliferative effects that are blocked by the actions of moexipril.
Prothrombin complex concentrate (PCC), also known as factor IX complex, is a medication made up of blood clotting factors II, IX, and X. Some versions also contain factor VII. It is used to treat and prevent bleeding in hemophilia B if pure factor IX is not available. It may also be used for reversal of warfarin therapy. It is given by slow injection into a vein.Common side effects include allergic reactions, headache, vomiting, and sleepiness. Other serious side effects include blood clots which may result in a heart attack, stroke, pulmonary embolism, or deep vein thrombosis. Antibodies may form after long term use such that future doses are less effective.Prothrombin complex concentrate came into medical use in the 1960s. It is on the World Health Organizations List of Essential Medicines. It is made from human plasma. Recombinant factor IX is also available in a stand-alone preparation. In the United States a dose of PCC costs about US$900. A number of different formulations are available globally. Medical uses
Prothrombin complex concentrate reverses the effects of warfarin and other vitamin K antagonist anti-coagulants and is used in cases of significant bleeding in people with a coagulopathy. It is also used when such a person must undergo an emergency operation. Other uses include a deficiency of one of the included clotting factors, either congenital or due to liver disease, and hemophilia.
