Blood levels of cyclosporine are increased if taken with grapefruit juice. A plausible mechanism involves the combined inhibition of enteric CYP3A4 and P-glycoprotein, which potentially leads to serious adverse events (e.g., nephrotoxicity).Blood levels of tacrolimus (Prograf) can also be equally affected for the same reason as with cyclosporine.
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?
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.

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%.
went to see a urologist saturday 19th sept after talking to him he told me that i may need to take a procedure called a penile doppler but in the mean time he prescribed levitra i would like to no if its safe and is there did it worked for you or anybody you know
I have been prescribed Levitra and viagra for the past ten years and they have worked well. I was talking mainly 20mg Levitra. A few months ago this only resulted in a less than satisfactory "half erection" and that has been the case since. However I have been woken during the night with a good erection so the "plumbing must still be working.
The testosterone shots decreased your body's mechanism that normally would have stimulated your testes to produce testosterone. Now that you are not taking the shots, this mechanism may start working again and your testes may grow. But I am not sure that this will happen. A serum LH (luteinizing hormone) level may help to give you an idea about what is happening. If this is low, your body is not resuming this stimulation at this point.
I’ve not heard of this condition before and it’s not happened to me before now. It began last week when I took a Levitra to have sex with my spouse. All was well, and I was lasting extra long. She was finished, and then I kept trying for a while, but I could not. She tried other ways to help, but no luck. I haven’t been able to orgasm through any method since then. What does this sound like, and what can I do about it? I am a Type 2 Diabetic, and take Metformin, Januvia, and Zoloft for anxiety.

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.
although I agree that overdoing it on the masturbation can lead to problems, refraining for 30 days (and after that, what's permitted ?) is not very practical. It's called 'self pleasuring' for a reason - it's pleasurable. Refraining in order to make oneself more excited about sex - a good idea in theory, but the 'cure' will probably be too restrictive for most males.
hi i'm 50 years old and dabetic so i'm taking levitra for erctil disfunction for five years but i'm notice my penis sudely become shorter and curve and with a litte pain at the end of the intercourse do i have demage my penis

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.
I'll try to keep this brief, but want to include some medical and overall life details. I'm 41, been divorced for just over five years, and met a lady a little over two months ago, and we've fallen in love quickly. I'm not used to falling fast, but I don't regret it. We decided we wanted to be intimate last night, but it didn't work too well. It's been about a year and a half since my last sexual experience.

Hi, 3 weeks ago I used a 5mg levitra sample for performance anxiety, that morning I woke up with a very hard erection, but ever since then my penis when flaccid is very hard to the touch, I have lost spontaneous erections and morning erections. Have I caused permanent damage? Will it become soft again? I was worried I had priapism whilst sleeping with levitra in my system but am unsure. Do you know why my penis feels hard in the flaccid state??
