- Absorption, oral: time to peak concentration 7h
- Elimination half-life = 12 h
(It says also that in general it can be administered once daily because it has a 24 h effect.Why?)
- Can you give another example to clarify it better please?
- When it says divide in 2 doses , does it mean only in the morning and dinner? 3 doses (morning-lunch-dinner)?
Thank you for taking the time to answer!!
You are correct that Truvada is a combination of tenofovir and emtricitabine, and is generally prescribed for patients with HIV. Being a HBV forum, most of us know very little about Truvada except that it is prescribed off-label for HBV by some doctors, and that it is recommended for HBV patients who develop resistance to Tenofovir.
I was also a reciever. After 40 hours I went to the first clinic and they gave me PEP (TenofovirDF, emtricitabine + lamivudine). The clinic looks very unprofessional, but it was my only chance. I didn't do any hiv or std test, a month before the exposure i had HIV test which was negative. After few days I had a mild sore throat, i still have it, i don't have fever, running nose, rash or anything else. My questions are..
An international study found the antiviral combination of tenofovir and emtricitabine (Truvada) was most effective in treating younger adult hepatitis B patients with high viral load and normal ALT levels.
Doctors historically have not treated this group because there appeared to be no sign of liver damage. However, doctors now know that high viral loads may increase patients’ risk of liver damage and cancer as they age, despite their normal ALT levels.
What are my chances of getting infected. Another question was administered a PEP drug emtricitabine and tenofovir, can it prevent me from contracting HiV.
FTC is Emtricitabine.
This is a potential concern because the drugs in Truvada – tenofovir and emtricitabine – are active against HBV as well as HIV.
HIV and HBV are spread through some common transmission routes, including sexual transmission, vertical transmission (mother to child) and via multi-person use of injection equipment.
I asked her of her status and she stated clean. I started PEP within 24 hours. (Teneogovir, emtricitabine, lamivudine ) What are the odds of being infected ? is this low risk ?
I started a course of PEP that included Tenvor-EM (Indian version Emtricitabine/Tenofovir DF) and Kaluvia (generic of lopinavir/retonavir) for 25 days and interrupted it for two reasons:
1-My partner tested Negative(Antigen/ Antibody) on 22 days post exposure
2-Thinking that i might be developing facial Lipodystrophy (slight facial fat loss under cheek bones). I cant tell if my face was like this before the treatment or it is just an illusion.
Good afternoon. There is a double-acting drugs - lamivudine, emtricitabine, tenofovir. This is known. Are there any similar action in the protease inhibitor, such as Kaletra (lopinavir) for example?
Have you ever thought about that?
I read - sometimes laugh. Simvastatin, vitamin D, which the Chinese poeben, mythical new drugs, masturbation with measurements of the level of HBsAg, and other nonsense....
m thinking about taking Tenofovir only because I will move to a place where Emtricitabine is not available. I know it is better to combo. But can you tell me how risky it is if I take tenofovir only (LAM resistance)? stef2011?
I can't help out on the pharmacokinetics, but your reasoning is sound: it doesn't make sense to dose so that the drug runs out.
I'd query Schering-Plough as well as your hepatologist, if I were you.
Please give me a heads-up if you solve the riddle.
truvada is just tenofovir+ftc, it is sueless on hbv unless non response to tenofovir, which is extremely rare
it adds toxicity and higher price because truvada patent is not expiring in 2014, no difference on hbsag.
instead of truvada it is best only for those non responding to combo tenofovir+lamivudine.
the second component is unchanged, 200mg of emtricitabine, also called FTC, a fluor substituted form of Lamivudine, that provides protection from the development of mutants that will lower the responsiveness to tenofovir.
it's side effects are generally considered very mild, equivalent to lamivudine.
This is theoretically good news for hbv patients waiting eagerly for TAF to be available for HBV.
The problem is the high price: 1500$ for one month supply of 30 pills.
Hepatic Impairment
In volunteers with hepatic impairment (Child-Pugh Class A and B), sildenafil clearance was reduced, resulting in higher plasma exposure of sildenafil (47% for Cmax and 85% for AUC). The pharmacokinetics of sildenafil in patients with severely impaired hepatic function (Child-Pugh Class C) have not been studied. A starting dose of 25 mg should be considered in patients with any degree of hepatic impairment [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3)].
