PDE3s belong to the phosphodiesterases family, where the PDE3A isoform is the major subtype in platelets involved in the cAMP regulation pathway of platelet aggregation. PDE3A inhibitors have been designed as potential antiplatelet agents. In this work, a homology model of PDE3A was developed and used to obtain the binding modes of bicyclic heteroaromatic pyridazinones and pyrazolones. Most of ...
BACKGROUND Pyrazolones are the most common causes of selective nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity. We studied a large group of patients with immediate and delayed selective responses to metamizole. METHODS Patients with suspicion of hypersensitivity to metamizole were evaluated. We verified acetylsalicylic acid tolerance and classified patients as immediate or delaye...
New heteroleptic complexes (1-8) containing Zn(II) ion coordinated to an N,N-chelating ligand (the 4,4'-dinonyl-2,2'-bipyridine, bpy-9) and to diketonates L such as tropoloids (Tropolone and Hinokitiol) or 1-phenyl-3-methyl-4-R-5-pyrazolones have been synthesized by using different stoichiometric ratio with respect to the L ancillary ligand. The molecular structure of the bis-tropolonate deriva...
BACKGROUND Several studies have identified neuromuscular blocking agents as the most common cause of anaphylaxis during general anesthesia. The reported frequencies vary considerably between countries. There are few reports from Spain, probably due to the low prevalence of reactions. METHODS For 5 years (1998-2002), all the patients who presented perioperative anaphylactic-type reactions, wer...
OBJECTIVE To determine the prevalence of potential clinically relevant drug- drug interactions in adult oncological inpatients, as well as to describe the most frequent interactions. A standard database was used. METHOD An observational, transversal, and descriptive study including patients admitted to the Oncology Service of a reference hospital. All prescriptions were collected twice a w...
Nonsteroidal anti-inflammatory drugs (NSAIDs) are used throughout the world to treat pain and inflammation; however, they can trigger several types of drug hypersensitivity reactions (DHRs) in all age groups. Although most such reactions occur through activation of the leukotriene pathway without specific immunological recognition (cross-intolerance), a significant number of DHRs to NSAIDs are ...
