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.
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).
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.
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?
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.
Thank you for your question,
Yes, it is recommended you take it in the morning on an empty stomach, at least 30 minutes before food. Taking levothyroxine with food may cause reduced bioavailability and may lower drug levels leading to signs or symptoms of hypothyroidism. In addition, cottonseed meal, walnuts, and dietary fiber may decrease absorption of levothyroxine from the GI tract.
Often I’ve had twitching in various parts of my body, even my eyelid, and after taking a magnesium supplement (Magnesium citrate is one of the best and has very good bioavailability; Magnesium Oxide is not recommended because of its very poor bioavailability!), my twitches stopped within a day! It’s easy to find on Amazon. I only mention these things because it is common to have low Vitamin D as well as low Magnesium. I hope your husband is feeling better soon.
If you are interested in enhanced bioavailability, the Swanson product included Bioperine, which can reportedly more than double the bioavailability. At 17 cents per 500 mg of curcuminoids, Life Extension Super Curcumin with Bioperine was also a good value. Products that include BCM-95 may have even greater bioavailability (about seven times that of normal curcumin).
It could be a psychological effect or a minor change in the composition of the in active ingredients because bioavailability (how much drug is actually available) of the drug is usually the same. If you do not get pain relief from zapain, you could ask your doctor to re-prescribe co-codamol. Take care!

Vitamins esp (ADEC) as well as calcium are better absorbed in a food state. Calcium citrate is more bioavailable then calcium bicarbonate. Checking the bioavailability for each vitamin supplement takes too much work for me so I just eat the foods directly.
Take 25% of those morphine mg per hour numbers above and that will yield the bioavailability of morphine (i.e.,how much of the dose in the pill is actually active towards relieving your pain). Don't let the bioavailability fool you into thinking you are not getting enough medication for your pain. Bioavailabilities can be extremely low and still provide sufficient pain relief as the manufacturer puts enough mgs in the pill to ensure the patient is receiving a therapeutic dose.
There have been several studies that showed the bioavailability of ribavirin increased with a high fat meal. The question is how much fat. My guess is to take with some fat (10 g?), not the 20 g needed for Inc. This has been discussed frequently on the forum if you care to search more.

Effect of Food on Absorption of Ribavirin
Bioavailability of a single oral dose of Ribavirin was increased by co-administration with a high-fat meal.
Food enhanced the exposure of boceprevir by up to 65% at the 800 mg three times daily dose, relative to the fasting state. The bioavailability of boceprevir was similar regardless of meal type (e.g., high-fat vs. low-fat) or whether taken 5 minutes prior to eating, during a meal, or immediately following completion of the meal. Therefore, VICTRELIS may be taken without regard to either meal type or timing of the meal.
It is only present in suboxone to prevent abuse (people using suboxone interveinously) and nothing more. It has a low bioavailability when taken orally, and is overpowered by the Bupe in the suboxone, which has a higher bioavailability. The other drug is wasted and expelled along with the other opiates you were taking.
Yes, although the generic manufacturers are supposed to duplicate the exact chemical composition of the name- brand drug that they make, I happen to know that there are differences in the peak serum levels. I used to sell generic drugs and know that there are subtle differences. We used to provide BA/BE studies for our pharmacists and physicians - that's bioavailability and bioequivalency studies, which show things like the peak serum levels, etc.
