Macrolide antibiotics

See also Methadone General information The basic structure of the macrolide antibiotics is characterized by a lactonic cycle with two osidic chains, and they are classified according to the number of carbon atoms in the cycle: 14-membered macrolides (for example clarithromycin, dirithromycin, erythromycin, roxithromycin, troleandomycin), 15-membered macrolides (for example azithromycin, an azalide), and 16-membered macrolides (for example josamycin, midecamycin, spiramycin). The azalides, such as azithromycin, are…

Lysine acetylsalicylate

See also Acetylsalicylic acid General information Lysine acetylsalicylate is a soluble form of salicylate developed for intravenous administration in acute pain. Its mode of action and scope of adverse reactions are similar to those of aspirin [ ], although it has a faster onset of action [ ] and causes less gastrointestinal bleeding [ ]. Lysine acetylsalicylate has been used as a challenge test in diagnosing…

Lysergide

See also Cannabinoids General information Lysergide (lysergic acid diethylamide, LSD) is a hallucinogen that is usually taken orally. Its initial effects, anticholinergic and sympathomimetic in type, occur within about half an hour and include tachycardia, hyperthermia, mydriasis, piloerection, hypertension, and occasionally nausea and vomiting. The more important psychoactive effects develop 1–2 hours later and can last 24–48 hours. They are principally changes in perception, mood, and…

Loxoprofen

See also Non-steroidal anti-inflammatory drugs (NSAIDs) General information Data on the safety of loxoprofen are based on an open, multicenter trial of about 4000 elderly patients in Japan [ ]. Adverse reactions were mainly gastrointestinal, but other adverse effects, common to every NSAID, included edema, dizziness, skin rashes, pruritus, and a case of eosinophilic pneumonia and liver dysfunction [ ].

Loxapine

General information Loxapine is a dibenzoxazepine neuroleptic drug. After 6 and 12 weeks of treatment with loxapine, patients with schizophrenia (n = 24; aged 18–70 years) showed both lymphocyte D2 dopamine-like and 5HT2A platelet receptor binding down-regulation, which suggests that both receptors are involved in the mechanism of action of the drug, as well as possible extrapyramidal adverse reactions [ ].

Lovastatin

See also HMG coenzyme-A reductase inhibitors General information The adverse events profile of lovastatin in 8245 patients with moderate hypercholesterolemia has been evaluated in a double-blind, diet- and placebo-controlled trial [ ]. The difference between lovastatin and placebo in the incidence of adverse events that required discontinuation was small, ranging from 1.2% at 20 mg bd to 1.9% at 80 mg Among a variety of symptoms,…

Losartan

See also Angiotensin II receptor antagonists General information Losartan is a non-peptide, selective angiotensin type 1 (AT1) receptor antagonist. Because it has been suggested that there is a local renin–angiotensin system in the eye, losartan may be useful in treating glaucoma. In a small, well-designed, placebo-controlled, crossover study in four groups of subjects—controls, hypertensive patients with normal intraocular pressure, and patients with primary open-angle glaucoma with…

Lornoxicam

See also Non-steroidal anti-inflammatory drugs (NSAIDs) General information Data are insufficient to indicate whether the oxicam NSAID lornoxicam is safer for the gastrointestinal tract than other oxicam derivatives [ ].

Lorenzo’s oil

General information Lorenzo’s oil is a 4:1 mixture of glyceryl trioleate and glyceryl trierucate. It is used in patients with adrenoleukodystrophy. The dyslipidemia in patients with adrenoleukodystrophy consists of increased blood concentrations of very-long-chain saturated fatty acids, particularly hexacosaenoic acid (C26:0). Treatment with Lorenzo’s oil has tended to normalize the abnormality in the blood while the patient deteriorates. Neurological changes are unrelated to the fatty acid…

Lorcainide

See also Antidysrhythmic drugs General information The clinical pharmacology, clinical use, efficacy, and adverse effects of lorcainide have been reviewed [ ]. The adverse effects of lorcainide may be partly caused by its active metabolite, norlorcainide, which accumulates during treatment [ ]. Organs and systems Cardiovascular Cardiovascular effects of lorcainide are reportedly uncommon (under 1% of cases) and have mostly been associated with intravenous administration. They…
