RESUMO
The physical and chemical compatibility of an enteral diet (standard Precitene) with a series of liquid preparations included in the hospital's formulary was evaluated. These preparations are included in the following groups: vitamins, antibiotics and chemotherapeutic drugs, analgesics, antiepileptic drugs, neuroleptics, bronchodilators, expectorants, antihistamines, immunosuppressors and short chain triglycerides. Phase separation, particle growth pH variation, osmolality increase and viscosity increase were studied. The results obtained indicate that the majority of the drugs studied are compatible from a physical and chemical point of view with the enteral diet used, at least during a 24 hour period, with the exception of those drugs which, because of their pH, acidify the mixture, causing problems of increased viscosity and particle growth, and of those liquid preparations of continuous oleous phase where phase separation is unavoidable. Lastly, a series of recommendations are given on cases where joint administration of drugs with enteral nutrition is suitable.

Lysinuric protein intolerance (LPI) or dibasic amino acid aminoaciduria is an unusual metabolic illness which, in countries where it is most common, affects one individual for every 60,000-80,000 births, and which is characterised by the inability to transport dibasic amino acids to the interior of the different cells of the organism. This paper sets out the design for an enteral modular formula for a pediatric patient very probably suffering from LPI. The formula has a very limited protein content, and incorporates L-citruline, a non-proteinogenic amino acid which intervenes in the urea cycle.
