Objective. The study aimed to evaluate the influences of coadministration of antiepileptic drugs (AEDs) on an antimalarial candidate 99/411 pharmacokinetic (PK) profile. Method. For this, single oral dose PK drug interaction studies were conducted between 99/411 and FDA approved AEDs, namely, Phenytoin (PHT), Carbamazepine (CBZ), and Gabapentin (GB) in both male and female SD rats, to assess th...

This study was conducted to evaluate the likelihood of daprodustat to act as a perpetrator in drug-drug interactions (DDI) with the CYP2C8 enzyme and OATP1B1 transporter using the probe substrates pioglitazone and rosuvastatin as potential victims, respectively. Additionally, this study assessed the effect of a weak CYP2C8 inhibitor, trimethoprim, as a perpetrator of a DDI with daprodustat. Thi...

Coadministration of azoles and vincristine has been shown to increase vincristine neurotoxic effects due to the inhibition of cytochrome P450 (CYP) isoform 3A4, for which vincristine is a substrate. Despite the absence of any casual relationship between seizure and coadministration of azoles, few case reports of vincristine-induced seizure have been documented after coadministration of fluconaz...

BACKGROUND Women of childbearing age represent a growing proportion of people living with HIV. Preventing pregnancy is important in HIV-infected women receiving efavirenz as part of their antiretroviral therapy. METHODS The effects of coadministration of efavirenz (600 mg once daily) on the pharmacokinetics (PK) of the active components (ethinyl estradiol [EE] and 17-deacetyl norgestimate [NG...

BACKGROUND The aim of this study was to determine the impact of fluvoxamine, an inhibitor of Cytochrome P450 (CYP) 2C19 (CYP2C19), on the pharmacokinetics of escitalopram, a substrate of CYP2C19. METHODS Thirteen depressed patients initially received a 20-mg/d dose of escitalopram alone. Subsequently, a 50-mg/d dose of fluvoxamine was administered because of the insufficient efficacy of escit...

BACKGROUND Minocycline and a non-steroidal anti-inflammatory drug (NSAID) indomethacin, have anti-inflammatory activities and are both used in the management of rheumatoid arthritis. However, there are no reports on whether coadministration of these drugs could potentiate each other's activities in alleviating pain and weight bearing deficits during arthritis. METHODS LPS was injected to BALB...

introduction: ghrelin increases growth hormone secretion and food intake. growth hormone (gh), steroid hormones and opioids are involved in the regulation of food intake. so, they may have a role in the regulation of ghrelin secretion. we determined the effect of intravenous injections of progesterone, gh and morphine or co-administration of these hormones on ghrelin concentration and body weig...

background: clopidogrel is a prodrug that converts in the liver to an active thiol metabolite, which irreversibly inhibits the platelet p2y12 adenosine diphosphate receptor. it seems that methadone as cyp2c19 inhibitor affects ticlopidine activity in vivo. this study aimed to test the ability of methadone in changing ticlopidine pharmacokinetics. methods: we conducted a case–control study in 10...

CONTEXT Drugs are related to the etiology of acute pancreatitis in approximately 1.4-2.0% of cases. Although antibiotics constitute a small number of the drugs suspected, tetracycline is the most encountered antibiotic among those drugs. CASE REPORT A 33-year-old woman was admitted to the emergency room complaining of nausea and abdominal pain after the use of doxycycline 500 mg and ornidazol...
