Description
Didanosine is an orally active purine dideoxynucleoside analog indicated for adult and
pediatric patients with advanced HIV infection who are either intolerant or significantly
deteriorated on zidovudine. It appears to increase CD4 cell counts and decrease p24
antigen levels.Major adverse effects are pancreatitis, peripheral neuropathy and
diarrhea.Unlike zidovudine, didanosine exhibits insignificant bone marrow
suppression.
-
Uses
Antiviral;Transrcriptase inverse
inhibitor 2?,3?-Dideoxyinosine is a potent anti-retroviral agent. It is most effective in combination therapy for the treatment of HIV and related lymphoma.
-
Indications
Didanosine (ddI, Videx) is an adenosine analogue with
activity against HIV-1, HIV-2, and HTLV-I. It is approved
as part of a multidrug regimen for the therapy of
HIV infection and is also used as postexposure HIV
prophylaxis
-
Therapeutic Function
Antiviral
-
Clinical Use
The most common adverse effect produced by didanosine
is diarrhea.Abdominal pain, nausea, vomiting,
anorexia, and dose-related peripheral neuropathy may
occur. Pancreatitis occurs rarely, as do hyperuricemia,
bone marrow suppression, retinal depigmentation, and
optical neuritis. Resistance to didanosine appears to result
from mutations different from those responsible for
zidovudine resistance.
-
Drug interactions
Potentially hazardous interactions with other drugsAllopurinol: concentration of didanosine increased
- avoid.Antibacterials: ciprofloxacin, tetracyclines, and other
antibiotics affected by indigestion remedies - do not
administer within 2 hours of didanosine.Antivirals: absorption of atazanavir reduced (give
at least 2 hours before or 1 hour after didanosine
tablets); manufacturer of darunavir advises to take
didanosine 1 hour before or 2 hours after darunavir;
didanosine tablets reduce absorption of indinavir
(give at least 1 hour apart); concentration possibly
increased by ganciclovir, valganciclovir and tenofovir
- avoid with tenofovir; give didanosine and ritonavir
at least 2.5 hours apart; increased risk of side effects
with ribavirin and stavudine - avoid; concentration
reduced by tipranavir (give tipranavir and didanosine
capsules at least 2 hours apart); give didanosine 2
hours before or 4 hours after rilpivirine.Cytotoxics: increased risk of toxicity with
hydroxycarbamide - avoid.
Orlistat: absorption of didanosine possibly reduced.
