  2. Bioavailability - Wikipedia

    en.wikipedia.org/wiki/Bioavailability

    Therefore, a drug given by the intravenous route will have an absolute bioavailability of 100% (f = 1), whereas drugs given by other routes usually have an absolute bioavailability of less than one. If we compare the two different dosage forms having same active ingredients and compare the two drug bioavailability is called comparative ...

  3. Equianalgesic - Wikipedia

    en.wikipedia.org/wiki/Equianalgesic

    Simply switching the patient from 40 mg of morphine to 10 mg of levorphanol would be dangerous due to dose accumulation, and hence frequency of administration should also be taken into account. There are other concerns about equianalgesic charts. Many charts derive their data from studies conducted on opioid-naive patients.

  4. Hydromorphone - Wikipedia

    en.wikipedia.org/wiki/Hydromorphone

    Hydromorphone is a rapid-acting painkiller; however, some formulations may last up to several hours. Patients who stop taking this drug abruptly may experience withdrawal symptoms, [28] [30] which may start within hours of taking the last dose of hydromorphone, and last up to several weeks. [26]

  5. Area under the curve (pharmacokinetics) - Wikipedia

    en.wikipedia.org/wiki/Area_under_the_curve...

    Absolute bioavailability refers to the bioavailability of a drug when administered via an extravascular dosage form (i.e. oral tablet, suppository, subcutaneous, etc.) compared with the bioavailability of the same drug administered intravenously (IV). This is done by comparing the AUC of the non-intravenous dosage form with the AUC for the drug ...

  6. Route of administration - Wikipedia

    en.wikipedia.org/wiki/Route_of_administration

    Routes of administration are usually classified by application location (or exposition). The route or course the active substance takes from application location to the location where it has its target effect is usually rather a matter of pharmacokinetics (concerning the processes of uptake, distribution, and elimination of drugs).

  7. Hydrocodone - Wikipedia

    en.wikipedia.org/wiki/Hydrocodone

    Oral hydrocodone has a mean equivalent daily dosage (MEDD) factor of 0.4, meaning that 1 mg of hydrocodone is equivalent to 0.4 mg of intravenous morphine. However, because of morphine's low oral bioavailability , there is a 1:1 correspondence between orally administered morphine and orally administered hydrocodone.

  8. Loop diuretic - Wikipedia

    en.wikipedia.org/wiki/Loop_diuretic

    A bolus intravenous dose of 10 or 20 mg of furosemide can be administered and then followed by intravenous bolus of 2 or 3% hypertonic saline to increase the serum sodium level. [12] Pulmonary edema - Slow intravenous bolus dose of 40 to 80 mg furosemide at 4 mg per minute is indicated for patients with fluid overload and pulmonary edema. Such ...

  9. Furosemide - Wikipedia

    en.wikipedia.org/wiki/Furosemide

    Furosemide is a known ototoxic agent generally causing transient hearing loss but can be permanent. Reported cases of furosemide-induced hearing loss appeared to be associated with rapid intravenous administration, high dosages, concomitant renal disease, and coadministration with other ototoxic medication.
