Aliskiren

See also Renin inhibitors, direct General information Aliskiren is an orally active, non-peptidic inhibitor of renin, and is the only direct renin inhibitor approved for the treatment of hypertension. Its potential adverse effects and a comparison with other renin–angiotensin blockers have been reviewed [ ]. Aliskiren is a novel compound that was developed by the use of X-ray crystallography of the active site of renin and…

Aliphatic alcohols

General information The lower aliphatic alcohols (ethanol, isopropanol, 2-propanol, N -propanol, and 1-propanol) are widely used for skin antisepsis. In appropriate concentrations, these alcohols are bactericidal to most of the common pathogenic bacteria, but some rare species survive and can grow, especially since these alcohols are inactive against dried spores. Seven cases of gaseous edema were observed in the former German Democratic Republic (GDR) after intramuscular…

Alfuzosin

See also Alpha-adrenoceptor antagonists General information Alfuzosin is a uroselective alpha 1 -adrenoceptor antagonist used to relieve the symptoms of prostatic hyperplasia [ ]. Its safety has been investigated in a large prospective 3-year open trial in 3228 patients with benign prostatic hyperplasia. There were no unexpected adverse effects. Only 4.2% of the patients dropped out owing to adverse effects. In a large database of 7093…

Alfentanil

See also Opioid analgesics General information Alfentanil is a potent short-acting opioid used in anesthesia. Beside its effects on opioid receptors, there is some evidence that it may affect acetylcholine, since intrathecal neostigmine produced a dose-dependent increase in the effect of alfentanil [ ]. Its rapid onset and short duration of action make alfentanil suitable for use in day care, although it is important to treat…

Alemtuzumab

See also Monoclonal antibodies General information Alemtuzumab (campath-1H) is a humanized monoclonal antibody specific for the CDw52 antigen, present on cell membranes of lymphocytes and monocytes. It has been used for treatment of patients with rheumatoid arthritis and vasculitis, is being investigated for the treatment of chronic lymphocytic leukemia, and has been used to deplete circulating lymphocytes in patients with multiple sclerosis [ ]. In 2001,…

Alefacept

General information Alefacept is a bioengineered fusion protein of soluble lymphocyte function antigen (LFA-3) with Fc fragments of IgG1. It blocks the LFA-3/CD2 interaction necessary for activation and proliferation of memory effector T cells by binding to CD2 expressed on the surface of T cells. It has been used in the treatment of psoriasis and psoriatic arthritis. There has also been a small pilot study of…

Aldose reductase inhibitors

General information Aldose reductase inhibitors [ ] have been developed for the treatment of secondary complications in diabetes [ , ]. They include alrestatin, benurestat, epalrestat, fidarestat, imirestat, lidorestat, minalrestat, ponalrestat, ranirestat, risarestat, sorbinil, tolrestat, zenarestat, and zopolrestat. The aldose reductase inhibitors inhibit or reduce secondary complications induced by diabetes, specifically in tissues in which glucose uptake is not insulin-dependent (probably neural tissue, the lens, and…

Aldesleukin

General information Aldesleukin (interleukin-2, celmoleukin, proleukin, teceleukin) is produced by activated T lymphocytes and has pleiotropic immunological effects, including the proliferation of T lymphocytes. Non-glycosylated recombinant aldesleukin has been approved for the treatment of metastatic renal cell carcinoma [ ] and is also being investigated in other malignant neoplasms. Low-dose aldesleukin is a relatively safe treatment of HIV infection [ ]. The adverse effects of aldesleukin…

Alcuronium

See also Neuromuscular blocking drugs, non-depolarizing General information Alcuronium is a synthetic derivative of toxiferine, an alkaloid of calabash curare, and is a non-depolarizing relaxant with properties and adverse effects similar to those of D-tubocurarine. It is about twice as potent as D-tubocurarine, 0.15–0.25 mg/kg usually being adequate for abdominal relaxation, and has a similar onset time and a slightly shorter duration of action. It is…

Albumin

General information Adverse reactions to human serum albumin are uncommon and usually mild, such as itching and urticaria. Serious reactions are rare. A patient who has reacted violently to albumin on one occasion may tolerate it well on another after being given an antihistamine such as diphenhydramine [ ]. Aggregates present in protein preparations may be the cause of some reactions. Another postulated cause may be…

Albendazole

See also Benzimidazoles General information The benzimidazole antihelminthic drugs albendazole and mebendazole (qv) are commonly used to treat soil-transmitted helminth infections, such as gastrointestinal roundworms, hydatid disease, neurocysticercosis, larva migrans cutanea, and strongyloidiasis [ ]. They bind to nematode β tubulin and inhibit parasite microtubule polymerization, which causes death of adult worms after a few days. Although both albendazole and mebendazole are broad-spectrum antihelminthic drugs, their…

Alatrofloxacin and trovafloxacin

See also Fluoroquinolones General information Alatrofloxacin is a fluoronaphthyridone that is hydrolysed to the active moiety, trovafloxacin, after intravenous administration. This fourth-generation broad-spectrum fluoroquinolone has activity against Gram-positive, Gram-negative, anerobic, and atypical respiratory pathogens. Because it has significant hepatotoxicity, the list of appropriate indications for trovafloxacin has been restricted. In a multicenter, double-blind, randomized comparison of trovafloxacin 200 mg and clarithromycin 500 mg bd in 176…

Ajmaline and its derivatives

General information Ajmaline and its derivatives, prajmalium bitartrate (rINN; N-propylajmaline), lorajmine (rINN; chloroacetylajmaline), detajmium bitartrate (rINN), and diethylaminohydroxypropylajmaline, are Rauwolfia alkaloids. Their use is restricted by serious adverse effects, such as neutropenia and cardiac dysrhythmias, which have been reviewed [ ]. Other adverse effects include dizziness, headache, and a sensation of warmth after intravenous injection. Organs and systems Cardiovascular Ajmaline occasionally causes cardiac dysrhythmias [ ].…

Adrenoceptor agonists

General information Subtypes of adrenoceptors were first described by Ahlquist in 1948 [ , ]. Adrenoceptor agonists evoke physiological responses similar to those produced by stimulation of adrenergic nerves or the physiological release of adrenaline (see Table 1 ). For many of these responses it is currently possible to conclude that only an alpha-adrenoceptor or a beta-adrenoceptor is involved, and in some cases one can distinguish…

Adrenaline (Epinephrine)

See also Adrenoceptor agonists General information Note on nomenclature Although “epinephrine” is the recommended International Non-proprietary Name (rINN), there are good reasons why the name “adrenaline” should be preferred, based on usage, history, etymology, and, most importantly, risk of clinical errors [ ]. For these reasons, the name “adrenaline” is used in many pharmacopoeias, including the British and European Pharmacopoeias. Uses Adrenaline is a catecholamine with…
