[Dalbavancin: pharmacokinetic and pharmacodynamic parameters].

Dalbavancin is a new lipoglycopeptide antibiotic whose structure influences its pharmacokinetic profile. It is not absorbed after oral administration and is therefore administered intravenously. It is distributed through intracellular fluid, reaching adequate concentrations in the skin, bone, blister fluid and synovial fluid.

Safety and Efficacy Clinical Trials for SYL1001, a Novel Short Interfering RNA for the Treatment of Dry Eye Disease.

Purpose: To evaluate the efficacy and safety of SYL1001, a short interfering (si) RNA targeting the transient receptor potential cation channel subfamily V member 1 (TRPV1), for the treatment of dry eye disease (DED).

Methods: This study combines a phase I and two phase II clinical trials to test different doses of SYL1001 in a total of 156 healthy subjects and patients with DED. After 10 days of treatment, the primary efficacy endpoints were the effect on (1) the scoring in the Visual Analogue Scale (VAS) and Ocular Surface Disease Index (OSDI) questionnaires, and (2) ocular tolerance evaluated by corneal fluorescein staining and conjunctival hyperemia.

[Pharmacology of the antifungals used in the treatment of aspergillosis].

The treatment of invasive aspergillosis requires the use of drugs that characteristically have complex pharmacokinetic properties, the knowledge of which is essential to achieve maximum efficacy with minimal risk to the patient. The lipid-based amphotericin B formulations vary significantly in their pharmacokinetic behaviour, with very high plasma concentrations of the liposomal form, probably related to the presence of cholesterol in their structure. Azoles have a variable absorption profile, particularly in the case of itraconazole and posaconazole, with the latter very dependent on multiple factors.

Randomized pharmacokinetic study comparing subcutaneous and intravenous palonosetron in cancer patients treated with platinum based chemotherapy.

Background: Palonosetron is a potent second generation 5- hydroxytryptamine-3 selective antagonist which can be administered by either intravenous (IV) or oral routes, but subcutaneous (SC) administration of palonosetron has never been studied, even though it could have useful clinical applications. In this study, we evaluate the bioavailability of SC palonosetron.

Patients And Methods: Patients treated with platinum-based chemotherapy were randomized to receive SC or IV palonosetron, followed by the alternative route in a crossover manner, during the first two cycles of chemotherapy.

Anidulafungin dosing in critically ill patients with continuous venovenous haemodiafiltration.

Background: Anidulafungin is indicated as a first-line treatment for invasive candidiasis in critically ill patients. In the intensive care unit, sepsis is the main cause of acute renal failure, and treatment with continuous renal replacement therapy (CRRT) has increased in recent years. Antimicrobial pharmacokinetics is affected by CRRT, but few studies have addressed the optimal dosage for anidulafungin during CRRT.

Phase I clinical trial of SYL040012, a small interfering RNA targeting β-adrenergic receptor 2, for lowering intraocular pressure.

The objective of this study was to evaluate ocular tolerance, safety, and effect on intraocular pressure (IOP) of a topically administered small interfering RNA; SYL040012, on healthy volunteers. The study was an open-label, controlled, single-center study comprised of two intervals that enrolled 30 healthy subjects having IOP below 21 mmHg. SYL040012 was administered to one eye as a single dose to six subjects during interval 1.

Critical appraisal of bilastine for the treatment of allergic rhinoconjunctivitis and urticaria.

Bilastine is a second generation antihistamine indicated for the treatment of seasonal or perennial allergic rhinoconjunctivitis and chronic urticaria with a daily dose of 20 mg, in adults and children over 12 years of age. The efficacy of bilastine has been shown to be similar to that of the comparator drugs for the control of the nasal and nonnasal symptoms of allergic rhinoconjunctivitis, while also showing a subjective improvement in the quality of life and in overall clinical impression. For chronic urticaria the symptoms (itching and the development of papules) lessens from the second day of treatment onwards, in a similar way to other antihistamines used as comparators.

[Antibiotic use in patients with renal or hepatic failure].

Renal or hepatic failure implies the need adjust the dosage of antibiotics that are eliminated in active form through the kidneys or metabolized through the liver. In the first case, the dose should be reduced by 30% for each level of renal impairment (moderate and severe). In hepatic failure, there is no general rule, and the specific information provided for each antibiotic should be used.

Simultaneous determination of diosmin and diosmetin in human plasma by ion trap liquid chromatography-atmospheric pressure chemical ionization tandem mass spectrometry: Application to a clinical pharmacokinetic study.

Diosmetin (3',5,7-trihydroxy-4'-methoxyflavone) is the aglycone of the flavonoid glycoside diosmin (3',5,7-trihydroxy-4'-methoxyflavone-7-ramnoglucoside). Diosmin is hydrolyzed by enzymes of intestinal micro flora before absorption of its aglycone diosmetin. A specific, sensitive, precise, accurate and robust HPLC assay for the simultaneous determination of diosmin and diosmetin in human plasma was developed and validated.

A fast reverse-phase high performance liquid chromatographic tandem mass spectrometry assay for the quantification of clindamycin in plasma and saliva using a rapid resolution package.

A new method for the quantitative analysis of clindamycin in human plasma and saliva by liquid chromatography/electrospray ionisation tandem mass spectrometry (LC/ESI-MS/MS) has been developed using a rapid resolution C18 column (2.1 mm x 30 mm x 3.5 microm).

[Tenofovir: pharmacology and interactions].

Tenofovir is a nucleotide analogue and consequently its mechanism of action differs from that of nucleoside analogues. This drug is administered orally in the form of disoproxil ester, which is deesterified to achieve a bioavailability of more than 20%. This bioavailability slightly increases if tenofovir is taken with a fat-rich meal.

[Recommendations for antibiotic monitoring in ICU patients].

Monitoring plasma concentrations of antimicrobial agents used to treat infection in critically ill patients is one of the recommended strategies for improving clinical outcome. Drug monitoring has a double aim: to limit adverse events and to increase the effectiveness of the drugs. In clinical practice, however, this approach is mainly limited to monitoring plasma concentrations of vancomycin and aminoglycosides, although future extension to other antimicrobial agents would be desirable.

Bioequivalence of two oral formulations of triflusal capsules in healthy volunteers.

Triflusal (CAS 322-79-2) is an antiplatelet agent related to salicylates used in several European and Latin American countries in the treatment of cardiovascular diseases. The aim of this paper was to evaluate the bioequivalence of triflusal derived from two preparations using both parent drug and metabolite pharmacokinetic data. The bioavailabolity was measured in 24 healthy male Caucasian volunteers following a single oral dose (600 mg) of the test or reference products in the fasting state.
