1. Dear Drugs-Forum readers: We are a small non-profit that runs one of the most read drug information & addiction help websites in the world. We serve over 4 million readers per month, and have costs like all popular websites: servers, hosting, licenses and software. To protect our independence we do not run ads. We take no government funds. We run on donations which average $25. If everyone reading this would donate $5 then this fund raiser would be done in an hour. If Drugs-Forum is useful to you, take one minute to keep it online another year by donating whatever you can today. Donations are currently not sufficient to pay our bills and keep the site up. Your help is most welcome. Thank you.

Opiate use in the eldery!

Opiate use in the eldery!

  1. Spucky
    Pain treatment in the elderly is an important challenge to Western societies due to increasing numbers of old persons, their higher
    incidence of pain, and their greater susceptibility to adverse effects of pain medication. We provide an overview of the factors liable
    to influence opioid action in the elderly population.
    A major challenge for the physician prescribing opioids in the elderly is their greater risk of medication-associated problems.
    Thus, older patients suffer increased vulnerability to adverse drug effects and interactions, higher rates of polypharmacy, and more
    comorbidity. These problems are compounded by a relative lack of definitive published information. There is clearly a need for more
    research in this area.
    Aging affects opioid pharmacokinetics via altered body composition (distribution volumes) and organ function (liver = metabolism,
    kidney = excretion). Pharmacodynamics is affected via impaired neurotransmitter/peptide production and changed receptor
    affinities/populations. Older women may need less morphine analgesia postoperatively, while pain sensitivity tends to increase particularly
    in older men. However, the net effects of changes in opioid pharmacology with age on clinical opioid analgesia remain
    unclear, probably due to the significantly greater variability in body function with increasing age.
    Practical recommendations for opioid prescription in the elderly include meticulous review of indication for opioid use, not only
    initially but also at regular intervals thereafter. A policy of careful titration should be followed, with conservative choice of dosage
    on starting. Dosing intervals may need to be lengthened subsequently. Finally, it should be remembered that old persons do not
    necessarily need less opioid than younger ones.
