Bibliometric analyses at the research team level in the pharmacology and pharmacy (F&F) subfield allow in-depth analysis of the findings obtained at higher aggregation levels.
Publications of Spanish authors in pharmacological journals covered by the Science Citation Index (SCI) are studied and the most productive Spanish teams during 1986-1989 and 1990-1993 are identified through in-house programmes based on co-authorship analysis. Team composition is defined and team size, scientific output, productivity, expected impact factor and collaboration pattern of the most productive teams are analysed as well as its evolution over time.
The observed annual increasing rate in the number of publications and authors in the field (11%) was similar to that of the number of researchers in the Spanish scientific system (8%). The number of highly productive teams doubled from the first to the second period (28 and 61 teams, respectively). The average team size was 8 researchers, showing an average scientific output of 3 documents/year and an average, productivity of 1.7 publications per author and team in each period. Over the years, an increase in the expected impact factor (EIF) of the publication journals and significant changes in the team composition were observed. A total of 13 stable teams were identified, with a greater size and output than the rest of the groups, and showing an upward trend in their expected impact factor and international collaboration rate. Stable teams did not show the negative correlation between team size and productivity observed for the total of the highly productive teams.
The F&F subfield is in a very dynamic stage, with a great increase in the number of researchers, starting of new teams and consolidation of others. A trend was observed towards the concentration of activity in the most productive teams, that are the most visible internationally both in number of publications in the SCI and in the impact factor of the publication journals.
药理学与药学（F&F）子领域研究团队层面的文献计量分析能够深入剖析在更高聚合层面所取得的研究成果。
对科学引文索引（SCI）收录的药理学期刊中西班牙作者的出版物进行研究，并通过基于共同作者分析的内部程序确定1986 - 1989年和1990 - 1993年期间产出最高的西班牙团队。定义团队构成，并分析产出最高团队的团队规模、科研产出、生产力、预期影响因子和合作模式及其随时间的演变。
该领域观察到的出版物数量和作者数量的年增长率（11%）与西班牙科学系统中研究人员数量的年增长率（8%）相似。高产团队的数量从第一个时期到第二个时期增加了一倍（分别为28个和61个团队）。平均团队规模为8名研究人员，每个时期平均科研产出为每年3篇文献，每位作者和团队的平均生产力为每年1.7篇出版物。多年来，观察到出版期刊的预期影响因子（EIF）有所增加，团队构成也发生了显著变化。共识别出13个稳定团队，其规模和产出均大于其他组，且预期影响因子和国际合作率呈上升趋势。稳定团队并未呈现出高产团队整体所观察到的团队规模与生产力之间的负相关关系。
F&F子领域正处于非常活跃的阶段，研究人员数量大幅增加，新团队不断涌现，其他团队也在巩固。观察到一种趋势，即活动集中在产出最高的团队，这些团队在SCI出版物数量和出版期刊影响因子方面在国际上最为引人注目。
