Riba and fatty meals

Concerning taking riba with a fatty meal..How many grams of fat would be sufficient for proper riba absorbtion?

[RobertBeWell]

I don't think it really matters. The idea is to get a little fat in there, so either take them with a meal, or eat a "fat snack" before hand.

Example:

Avocado, peanut butter, trail mix bar, ice cream.

I'm sure you can find dozens of options. Personally, I take my first dose after breakfast, at which I always eat either some sausage, ham steak, or bacon. For the evening dose, I usually just have an ice cream bar and a trail mix bar, then down the meds. Once in a while I'll fix a peanut butter sandwich.

Tried avocado, but it was quite unappetizing to me.

I really had a hard time eating on treatment especially in the morning so when I really couldn't I'd at least have a yogurt shake or some peanut butter crackers.  You don't have to go nuts or anything.  Plus ice cream isn't a bad thing to have to suffer through ;)

For what it’s worth….

From Schering-Ploughs PEG-Intron prescribing info:

Effect of food on absorption of ribavirin:

Both AUC and C-MAX increased by seventy percent when Rebetol Capsules were administered with a high fat meal: (841 kcal, 53.8 g fat, 31.6 g protein, and 57.4 g carbohydrate) in a single-dose pharmacokinetic study.

LOL, that's like, eating a big mac and supersize order of fries twice a day. Perhaps not quite that much, but it's a substantial meal. If I ate like that twice a day, I'd gain 100 lbs over the course of treatment.

And something else just occurred to me. After a time, the Ribavirin, like the IFN, achieves a more or less steady-state serum level. Is there really any benefit to getting more? That is, I am assuming that the Ribavirin is manufactured, dispensed and prescribed in a manner that ACCOUNTS for the 45% absorbtion rate. In other words, the recommended dosage is probably based on assuming the patient IS NOT going to be eating like that twice a day.

Is it not so?

"After a time, the Ribavirin, like the IFN, achieves a more or less steady-state serum level."

For the IFN, that's true for Pegasys (interferon alfa-2a) anyhow. For PEG-Intron, I think the pharmacokinetics are substantially different. Just like to be clear.

LOL, but you'd be better off just letting the HepC run it's course and not bother treating, cause you'd live longer I'm betting.
