Atorvastatin is supposed to be one of the two most effective statins in lowing cholesterol so you are on a good one. Bioavailability is how well a med is absorbed and used by the body and bioavailability varies among the statins. It's actually a desired thing. The liver is the target organ so if it is slowed down in the liver (where this happens), it's in the target organ. But honestly, that is hard for me to understand.
i wouldnt lower the tacrolimus dose further
The specialist reviewed all of the options with us - cyclosporine, pilocarpine or tacrolimus with sirolimus. She said that very rarely has she seen any dog respond to cyclosporine after not responding to tacrolimus. She also said that because our dog doesn't have a dry, goopy nose, that pilocarpine wouldn't be a first choice. She recommended a mix of tacrolimus with sirolimus. She said sirolimus is new. I have not been able to find anything about this drug on the internet.
Although a standard meal did not affect ribavirin bioavailability (F1), administration of ribavirin with a high-fat meal increased bioavailability by 46% relative to the fasting state. A high-fat meal prolonged the duration of the zero-order input part of the absorption model, with D1 increasing from 0.498 h (fasting and standard meal) to 0.740 h. The type of meal also influenced the first-order input part of the absorption model (Table 1).
His cretanine is almost 1.4 or around. My question is that should he continue his TACROLIMUS tablets or should switch to some other tablets which are safe for kidneys?
Secondly , in my sorrounding there is an opinion that lowering the TACROLIMUS dose also let the liver enzymes to increase? Do you favour such opinions as my father has lowered his tacrolimus dose to keep his kidneys safe?
Sir ,will wait for your kind reply.
Thanks.
s hard to perform my job or other daily tasks when my eyelids are so inflamed. I guess steroids are the only option until they develop something better. Is Tacrolimus a promising nonsteroidal option?
The treatments of this condition are application of topical corticosteroids (betamethasone, clobatesol, flucinolone) which will reduce the inflammatory process. Topical immunomodulators like pimecrolimus and tacrolimus can be used in severe conditions.
I hope it helps. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor.
Hormonal contraceptives such as the pill and the patch may increase the blood level of tacrolimus. Tacrolimus may also reduce the effectiveness of these hormonal contraceptives. For this reason women who could get pregnant should ideally use a non-hormonal method of contraception, eg condoms, to prevent pregnancy while taking this medicine. Seek advice from your doctor or pharmacist.
there are prograf assistance programs that the company offers. If this is not feasible than using other cheaper medications such as verapamil for example for HTN for example will alllow much lower doses of prograf to be used (it delays metabolism of the medication) and thus it comes out cheaper.
AS I HAVE SUFFERED BREATHLESSNESS AND WALKING PROBLEMS,I HAVE BEEN TAKEN OFF TACROLIMUS AND PUT ON NEORAL-YET THERE IS NO IMPROVEMENT IN MY CONDITION.IS THERE ANY OTHER ANTI REJECTION DRUG THAT YOU WOULD RECOMMEND (I HAVE HAD A LIVER TRANSPLANT RECENTLY)? IN YOUR EXPERIENCE,CAN MY SITUATION BE IMPROVED?THANKS.
When a medication is administered intravenously, its bioavailability is 100%. However, when a medication is administered orally, its bioavailability decreases because not all of it is absorbed. So 70% bioavailability means that, from the dose you took, 70% of it reached systemic circulation.
"Two studies have been carried out to assess the effect of food (ie, a high-fat breakfast) on the bioavailability of a SINGLE oral dose of ribavirin. An initial study by ICN Pharmaceuticals, Inc.
Also as a side note, Opana oral bioavailability is actually very low. Lower than morphine I believe the bioavailability is around 10 percent. However, if you reach your optimal dose, bioavailability matters little.
I see that this post is from October 2011. But since I have this typed, I'll post anyway :) Good luck and gentle hugs.
i would be extremely cautious about using it until more data is available especially since its purported effects on tacrolimus and cyclosporine metabolism are extreme. i am quite confident that there will be clinical trials coming down the road extremely soon.
Blood tests are not accurate for testing the active bioavailability of sex hormones in the cells and tissues. They only test what's in the blood stream. They aren't accurate for testing when a patient is using bioidentical topical creams. I've had two holistic doctors tell me this and have read numerous articles about which testing is correct depending on which type of hormones you're taking.
The ascorbate in Ferrous Ascorbate helps retardation or prevention of Fe(II) oxidation by ascorbate and to the existence of Fe(II) as a chelate with ascorbate ( vitamin C if you like ). Ferrous Ascrorbate will have a better bioavailability but you can add a vitamin C and vitamins B complex with sodium feredetate and have pretty good results.
Depending on your needs; are you lacking iron? anemia?
My tacrolimus level is 4.2 after 4 months of liver transplant, Is it dangerous? what should i do?
Treatment is by topical steroids or oral therapy of corticosteroids in severe cases. Topical creams like tacrolimus ointment (Protopic) and pimecrolimus cream (Elidel) are also useful.
If still the symptoms do not improve then please get a clinical examination done by a dermatologist.
I hope it helps. Take care and please do keep me posted in case you have any additional doubts. Kind regards.
The component of the final population pharmacokinetic model that describes the absorption phase is complex. Although a standard meal did not affect ribavirin bioavailability (F1), administration of ribavirin with a high-fat meal increased bioavailability by 46% relative to the fasting state. A high-fat meal prolonged the duration of the zero-order input part of the absorption model, with D1 increasing from 0.498 h (fasting and standard meal) to 0.740 h.
