- 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!!
I took my first dose of Alendronate and then experience significant muscle pain for the next 4 days. Does anyone know if I should expect this to happen each time I take it or is it something to happen for the first few times until my body adjusts to the medicine?
Do you mean Fosamax (alendronate)? If you do, its for treating bone problems like Osteoperosis by adding bone mass and slows bone loss. I use it for Osteopenia.
The prescription drug Fosamax (the generic is alendronate sodium) is a medication which has been prescribed to hundreds of thousands of postmenopausal women to treat osteoporosis and help increase bone mass thereby reducing the chance of spinal or non-spinal fractures. Fosamax has also been prescribed to increase bone mass in men with osteoporosis. Brand name Fosamax is manufactured in the United States by Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc.
The authors examined the effects of high-dose oral alendronate (40 mg daily) for 6 months on 3 adult patients with intractable headache due to fibrous dysplasia of the skull. Each patient had disease processes not amenable to surgery. The patients underwent clinical follow-up at 1, 3, and 6 months. Their pain levels were documented at each visit by using a visual analog scale. All 3 patients demonstrated a significant decrease in pain levels and became independent of scheduled analgesics.
I am also taking Aromasin for bc. Stopped alendronate (I am osteopenic due to 30 yrs of prednisolone and Arimidex) in case this caused the oesophagitis. Would appreciate your advice.
thankyou,i am with contact of my doctor ,he said there is no solution for damaged vertibras,but calcium and vitiman d and alendronate sodium/cholecaiciferol tablets will help spine and bones from further damages but what to do with prednisones i cant stop them because of asthma and taking of them will damage other bones isnt there any other solution instead of prednisones, i know there is nothing accept these because my doctor told me:(

Osteoporosis medications like Raloxifene (Evista), alendronate (Fosomax), risendronate (Actonel) and ibandronate (Boniva) all can cause flu like symptoms in individuals that are taking them. I am not sure what medications you are on, but this could be your problem.
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.
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)].
Folic acid supplementation in folate-deficient patients with epilepsy changes the pharmacokinetics of phenytoin, usually leading to lower serum phenytoin concentrations and possible seizure breakthrough..."
It however says that initiation of Folic acid and phenytoin together is beneficial.
Since you can't go back and start all over again, you can take a small dose. It has been observed that as los as 1mg dose can perturb phenytoin’s levels, You may take doses lower than 1mg/day.
The Phase 1 trial was designed to characterize the safety profile of ARC-520 across a range of doses and evaluate pharmacokinetics. It is a single-center, randomized, double-blind, placebo-controlled, single dose-escalation, first-in-human study of ARC-520 administered intravenously to healthy adult volunteers. All subjects have been dosed and received either placebo or ARC-520 in doses ranging from 0.01 mg/kg to 2 mg/kg.
i believe in the pre-clinical trials with healthy volunteers, researchers used Carbon14 to gauge the half-life and paths of elimination during pharmacokinetics studies. it is a common practice. perhaps that is what you are thinking about?
Nitazoxanide, brand name alinia, had also excellent ed50 results in an in vitro inhibition study, just as good as lamuvidine, so this sounded fascinating for a possible combination towards true synergism, to finally suppress virion production to a level so low that the silent daily reinfection will be reduced, allowing a slow net clearance of infected cells with a resulting drop in surface antigen.
