Promoting appropriate drug use through the application of the Spanish drug-related problem classification system in the primary care setting.

Background: According to the Second Consensus of Granada (2002), the term drug-related problem (DRP) is defined as a health problem resulting from pharmacotherapy and is considered a negative clinical outcome (ie, a therapeutic objective is not achieved or adverse effects are reported). DRP classification systems used in primary care settings can be useful tools to detect, evaluate, and resolve DRPs.

Objective: To encourage appropriate drug use in the ambulatory clinical setting through DRP detection and evaluation by means of the Spanish DRP classification system, and to document how pharmacists can help resolve DRPs through interventions with both general practitioners (GPs) and patients.

Novel cationic and neutral glycocholic acid and polyamine conjugates able to inhibit transporters involved in hepatic and intestinal bile acid uptake.

To obtain novel drugs able to inhibit transporters involved in bile acid uptake, three compounds were synthesized by conjugating N-(3-aminopropyl)-1,3-propanediamine (PA) with one (BAPA-3), two (BAPA-6), or three (BAPA-8) moieties of glycocholic acid (GC) through their carboxylic group. The expected net charge in aqueous solutions was 2+ (BAPA-3), 1+ (BAPA-6), and 0 (BAPA-8). They were purified by liquid chromatography and their purity checked by HPLC before being chemically characterized by elemental analysis, NMR, and FAB-MS.
