Avatar m tn I am not physically restricted - I walk 1 mile or more day and do 10 minutes of other light exercises most days. My BP runs under 120/80 most of the time. I understand carvedilol helps prevent stiffening of the heart muscle and can help restore LV function to some degree. How specially, so it do this? What is the biochemical mechanism?
Avatar m tn The mechanism of action of Campral® (acamprosate calcium) Delayed-Release Tablets in maintenance of alcohol abstinence is not completely understood. Originally, several neurotransmitter systems, including GABA, were investigated for a possible role in Campral's mechanism of action. However, recent evidence suggests Campral's main interaction is with the glutamate system. Chronic alcohol exposure is hypothesized to alter the normal balance between neuronal excitation and inhibition.

Avatar m tn Oyakawa I am in my 3rd year of medical school and I was wondering the mechanism of action of steroid injections in the eyelid causing cataracts. It is not an osmotic agent so why does that occur? thanks so much.

Avatar f tn Plavix has a unique mechanism of action by blocking the amplification of platelet activation by released ADP, and often used with aspirin to prevent the risk of clots for the first year after DES implant. Plavix and aspirin have different mechanism of action to prevent clots. After a year, plavix is usually discontinue as the risk for clots is decreased, and aspirin is continued long term. The risk of a clot is about 3%.
Avatar f tn A Study to Evaluate the Safety and Effect of ABT-450, Ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333 Coadministered With Ribavirin (RBV) in Hepatitis C Virus (HCV) Genotype 1-infected Adults With Compensated Cirrhosis. (TURQUOISE-II) The purpose of this study is to evaluate the safety and effect of ABT-450, ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333 coadministered with ribavirin (RBV) in HCV genotype 1-infected adults with compensated cirrhosis.
163305 tn?1333668571 The regimen’s success may testify to the utility of RBV in preventing resistance, or possibly, as some have speculated, to high intrahepatic concentrations of ritonavir-boosted ABT-450, permitting suppression of low-level resistant variants. The lower SVR rates in null responders, associated with substantial relapse rates, reflect an important emerging and unanticipated theme—the importance of host pathways, reflected by IFN responsiveness, in mediating viral eradication with IFN-free regimens.
Avatar f tn I have been running around to find a pharmacist who can arrange the same for me but I am scared as hell. Is it allowed to miss a single dose of lopi/ritonavir. I need an urgent expert opinion on this. I am still trying my level best to get it. Can someone please tell me the effects of missing a single dose in this case. I am going to the clinic early in the morning tomorrow.
Avatar f tn It also contains ritonavir, a previously approved drug, which is used to increase blood levels of paritaprevir. Viekira Pak can be used with or without ribavirin, but it is not recommended for patients whose liver is unable to function properly (decompensated cirrhosis). “The new generation of therapeutics for hepatitis C virus is changing the treatment paradigm for Americans living with the disease,” said Edward Cox, M.D., M.P.H.
184420 tn?1326739808 SCH 900518, when added to the current standard of care (SOC), peginterferon-alfa plus ribavirin, would likely increase the proportion of patients achieving undetectable HCV-RNA levels and sustained virologic response (SVR). In this study, SCH 900518 would be used in combination with low doses of ritonavir to enhance the levels of SCH 900518 within the body and reduce the number of daily SCH 900518 tablets required.

Avatar f tn Potassium is a chemical element and it is part of the electrolyte that should be in balance with other lytes to adequately conduct an electrical impulse that originates with the sinus node in the right atrium. The mechanism of action is not completely understood, but what is when a voltage (unit of potential for conduction) and electrolyte there will conduction and passage of electrical impluses.
Avatar m tn http://www.medscape.com/viewarticle/578705 Ribavirin improves early responses to peginterferon through improved interferon signaling. Gastroenterology. 2010 Jul;139 The therapeutic mechanisms of ribavirin for hepatitis C are unclear. Microarray analyses have shown that ribavirin increases induction of interferon-stimulated genes. We evaluated viral kinetics, serum cytokine expression, and viral mutagenesis during early stages of peginterferon therapy with and without ribavirin.

2046312 tn?1360379600 Coadministration with telaprevir may increase the plasma concentrations of drugs that are metabolized by CYP450 3A4. The mechanism is decreased clearance due to inhibition of CYP450 3A4 activity by telaprevir. MANAGEMENT: Caution is advised if telaprevir must be used concomitantly with medications that undergo metabolism by CYP450 3A4, particularly those with a narrow therapeutic range.
220090 tn?1379167187 The first phase of treatment lasts 1 to 2 days. This phase kills most of the virus circulating in your bloodstream. The action of Interferon in your bloodstream is simple. It mainly slows down the replication of the virus. In order for any life form to survive, it must live long enough to reproduce. By slowing down the rate of replication, the virus dies on its own without producing offspring. Phase 2 lasts from day 2 through day 14.

Avatar n tn Some medications are actually derived from plants. The mechanism of action and effect on the body determines the classification, therefore, laxatives can be synthetic or natural.

Avatar n tn "Mechanism of Action Oxomemazine, a phenothiazine derivative, is a sedating antihistamine" The above information is about all I could find on this drug. If it is used in the US, I have no idea what label it's under. Even if I had been able to find more information, I am not qualified to tell you to either stop or start or change any medications. You need to speak with your doctor or chemist for an answer to your question.
Avatar f tn , duloxetine) has a combination mechanism of action involving serotonin and norepinephrine making it useful in depression and also neuropathic pain. When a peripheral nerve is injured there is an increase in pain sensitive fibers leading to increase pain recognition. This causes a change in central (i.e., brain/spinal cord) recognition of pain. One major neurotransmitter involved in this is norepinephrine. Cymbalta works to modulate this change.
Avatar n tn A heart murmur is a sound heard as the blood flows through the heart and especially the blood flow through the heart valves. If there is a defect, a stethoscope hears a specific sound for different defects. ■Angiotensin-converting enzyme (ACE) inhibitors. ACE inhibitors lower the system's blood pressure. The mechanism of action is to relax the blood vessels and that provides less resistance for the heart to pump against and decreases blood pressure.
Avatar f tn boceprevir is in pharmacies now telaprevir should be by the end of the month they both have the same mechanism of action ( protease inhibitors ) and are comparable in efficacy mimi that 70% is for first timers only
