viread patent expiry

It costs me HK$3,000 (US$400) a month in last 2 years. I expect the price to drop sharply after the patent expiry. But, it did not. Anyone has any idea ?

it is not more efficacious it has less toxicity than tdf on kidneys but also this is not an issue on hbv, until now it is more a way to patent a new version of tenofovir because viread will soon be out of patent, trials will confirm its utility but with all the new drugs coming out the next few years i dont see it as uselfull for hbv especially if viread will be much cheaper

Why? Gilead loses the patent on Viread in 2017/2018. Their cash cow will have run its course and they will be more than happy to release this drug to continue to reap the money for HBV treatment. There is one thing I remember Dr. Gish telling me that I won't forget. He said "you know Gilead is working on a drug that will make it so you don't have to take Viread for ever. It's kind of odd that they'd be working on a drug that will eliminate their Viread income".

I would think TAF in time will be approved for HBV too , just like Viread has. When TAF becomes approved it will come with that patent that Viread has now. No big surprise I read that TAF is said to get FDA approved around the time Viread's patent ends. Personally, I feel it's a big game the drug company uses to continue to make more money. Gilead knows Viread will be available as Generic in the near future, so they have to have a new Brand up and coming with TAF.

tenofovir disoproxil fumarate) is a prodrug of tenofovir. The 'disoproxil' is a side chain attached to the active component 'tenofovir'. Inside our body, this side chain gets cleaved off by an enzyme to release the active tenofovir. AGX-1009 has a different side chain attached to the active component 'tenofovir'. It may show higher potency and/or lower toxicity compared to Viread because of this different side chain (At least that's what Agenix is hoping for).

so it is not that if you buy in US you have a better chemical for sure viread itself is very cheap in india thanks to competition, entecavir lost patent, it had no rights to patent the compound, actually even tdf was an already know substance so india did not allow the patent by the way when i used nitazoxanide to try clear hbsag i had a test for purity on drugs said to be produced in US (they are not, they are produced in cheap countries and just relabeled), the worst was that produced in US

reduced bone density, more toxic to the kidneys, and possible changes in body fat. Viread offers a 5% chance of loss of HBsAg in 48 weeks while Baraclude offers a 5% chance in 96 weeks. Why not just take Baraclude?

My docter said she might want me to swith to viread but im thinking doesnt viread also warn about lactic acidos? Also could it be the fact that I was exercising recently that caused this?

My husband is currently taking Viread for HepB and his doctor told us that there is a 5-6% chance of birth defects if I become pregnant. Has anyone heard this before? I see that women who are the ones taking the med take it while pregnant so I'm a bit confused/hopeful.

why etv costs more than double tdf?why patent was illegal?why the drug development was not stopped when mice developed lung cancer knowing tdf was the most potent at a research and development level?why was tdf demonized with untrue sides effects to justify its prescription over tdf?

Would it be safe to use this unopened bottle as I have read that most medications are really good for 5 years after expiry and drug companies just put the expiry dates on so people will throw them away. I had my cataract surgery January 2011 so it is completely healed but I still have inflammation so I need to keep taking Voltaren eye drops.

not allowed on pregnancy, only tenofovir (viread) is good on preganancy, no resistance, most potent on hbv and even much cheaper than entecavir, it is also about to lose patent so it may become as cheap as indian generics which are as low as 21usd per month peginterferon must be used after 3-5 years on tenofovir to work and clear hbv, hbsag is cleared in 50% peginterferon monotherapy can work only for very low hbsag and very low hbvdna otherwise it is useless to try just 7% hbsag clearance yo

Also, how do they decide if you should be on viread tablets or on the injection (peginterferon)? If your on viread do you have to take it for life? And if you take the peginterferon injection then after one year if hbv dna is undetected can you stop taking all medication? Finally, is the coast of viread tabs close to a 1000dollars a month? Thats damn expensive.

Stefano and others, thanks for your help. As I posted before, 2 of my relatives are currently undergoing Hepsera monotherapy. I went to a new doctor for a second opinion and the Hepsera-prescribing current doctor for an explanation of treatment choice. The first doctor agreed that Baraclude and Viread are to be dispensed per current AASLD guidelines but, once you've started with Hepsera, there is no need to change. He felt that the resisitance rate for Hepsera (vs.

No don't stop viread and wait for a couple of month till taf arrives completely in market and then switch to it as is renosafe. Stopping viread will flush ur 8 years of virus control and chances to lose hbsag in future may go in vane.
