简要总结
This study is aimed to evaluate the bioavailability of methylprednisolone in healthy subjects of both genders, with administration intranasally versus intravenous
详细描述
The most important property of a drug dosage is its ability to deliver the active ingredient to the site of action in a quantity sufficient to exert the expected pharmacological effect. This ability is known as bioavailability. Methylprednisolone is a drug with wide clinical use in patients with inflammatory pathologies (infectious or non-infectious). The main routes of administration are oral and intravenous. The intranasal route could be one more effective, less invasive that would allow to obtain a faster therapeutic concentration and in greater concentration in the lungs and in the central nervous system than the intravenous route, maintaining very similar systemic concentrations to those achieved intravenously. For these reasons, it is important to know the bioavailability of methylprednisolone administered by this route in order to establish the best dosing regimen. The pilot study is of an exploratory nature (descriptive, comparative or informative), whose objective is to know the pharmacokinetic characteristics of a new route of administration of a drug in the study population to establish the pharmacokinetic parameters, and the comparison between the intranasal bioavailability against the intravenous administration by determining confidence intervals and calculating one-sided double t of Scuirmann.
Objetive: To evaluate the bioavailability of methylprednisolone in healthy subjects of both genders, with administration intranasally versus intravenous dose of 1 ml of methylprednisolone sodium succinate equivalent to 62.5 mg of methylprednisolone.

研究组 & 干预措施
Intravenously MEP
Single dose of MEP sodium succinate intravenously administered. MEP (equivalent to 62.5 mg of Methylprednisolone).
Samples were obtained at 0.333, 0.50, 0.667, 0.833, 1, 1.0, 2, 3, 4, 6, 8, 10, 12 and 24 h after MEP administration.
干预措施: Evaluation of bioavailability of methylprednisolone succinate administered intravenously (Drug)
Intranasally MEP
Volunteers were randomly assigned to receive a single dose of MEP intranasally administered (equivalent to 62.5 mg of Methylprednisolone), using a Mucosal Atomization Device (MAD Nasal). Samples were obtained at 0.333, 0.50, 0.667, 0.833, 1, 1.0, 2, 3, 4, 6, 8, 10, 12 and 24 h after MEP administration.

结局指标
主要结局
Absolute Bioavailability of Methylprednisolone, Intranasal Route vs. Intravenous Route
时间窗: 2 weeks
The sample size used for this exploratory study (descriptive, comparative or informative) made it possible to determine the absolute bioavailability (with informative value), for which the bioavailability was compared in the 2 types of administration: Intranasal vs. Intravenous with a sample size of 8 research subjects, even though the ANADEVA is informative, the requirements regarding type I error (alpha), type II error (beta) and a minimum difference to detect between the 2 routes of administration: intranasal vs. IV. The realization of the present study allowed to know the pharmacokinetic and safety parameters of the drug MEP administered by 2 different routes, as well as to determine the CVintra%
