| Loperamide | One of the long-acting synthetic antidiarrheals; it is not significantly absorbed from the gut, and has no effect on the adrenergic system or central nervous system, but may antagonize histamine and interfere with acetylcholine release locally. (PubChem) Pharmacology: Loperamide is a synthetic anti-diarrheal indicated for the control and symptomatic relief of acute nonspecific diarrhea and of chronic diarrhea associated with inflammatory bowel disease. Loperamide is also indicated for reducing the volume of discharge from ileostomies. In man, Loperamide prolongs the transit time of the intestinal contents. It reduces the daily fecal volume, increases the viscosity and bulk density, and diminishes the loss of fluid and electrolytes. Tolerance to the antidiarrheal effect has not been observed. Loperamide is an opioid receptor agonist and acts on the mu opioid receptors in the myenteric plexus large intestines; it does not affect the central nervous system like other opioids. It works specifically by decreasing the activity of the myenteric plexus which decreases the motility of the circular and longitudinal smooth muscles of the intestinal wall. This increases the amount of time substances stay in the intestine, allowing for more water to be absorbed out of the fecal matter. Loperamide also decreases colonic mass movements and suppresses the gastrocolic reflex. Mechanism of action: In vitro and animal studies show that Loperamide acts by slowing intestinal motility and by affecting water and electrolyte movement through the bowel. Loperamide inhibits peristaltic activity by a direct effect on the circular and longitudinal muscles of the intestinal wall. It is a non-selective calcium channel blocker and binds to opioid mu-receptors. Evidence also suggests that at higher concentrations it binds to NMDA receptors and to calmodulin. Drug type: Approved.

| Lopinavir | Lopinavir (ABT-378) is an antiretroviral of the protease inhibitor class. It is marketed by Abbott as Kaletra, a co-formulation with a sub-therapeutic dose of ritonavir, as a component of combination therapy to treat HIV/AIDS. Pharmacology: Lopinavir is an antiretroviral of the protease inhibitor class. Mechanism of action: Lopinavir inhibits the HIV viral proteinase enzyme which prevents cleavage of the gag-pol polyprotein, resulting in noninfectious, immature viral particles. Drug type: Approved. Small Molecule. Drug category: Anti-HIV Agents.

| Loracarbef | Loracarbef is a carbacephem antibiotic sometimes grouped together with the second-generation cephalosporin antibiotics. It is marketed under the trade name Lorabid. Pharmacology: Loracarbef is considered a second generation cephalosporin antibiotic. The advantages of cephalosporin antibiotics include a broad range of activity, a safe record in children with almost no dose-related toxicity, and the lack of need to monitor levels. Adverse reactions are rare and consist primarily of hypersensitivity reactions with urticaria, nonspecific rash, and pruritus. Loracarbef can be used to treat a large number of bacterial infections caused by gram-negative and gram-positive bacteria, including upper respiratory tract bacterial infections, chronic bronchitis, pneumonia, sinusitis, pharyntitis and tonsillitis, skin absceses, urinary tract infections and pyelonephritis caused by E. coli, S. pyogenes, S. aureus, S. saprphyticus, S. penumoniae, H. influenzae and M. catarrhalis. Mechanism of action: Loracarbef is an oral, synthetic beta-lactam antibiotic of the carbacephem class. Chemically, carbacephems differ from cephalosporin-class antibiotics in the dihydrothiazine ring where a methylene group has been substituted for a sulfur atom. Loracarbef has a spectrum of activity similar to that of the second generation cephalosporins. It is structurally identical to cefaclor except for a sulfur atom that has been replaced by a methylene group. This change gives greater chemical stability in solution and allows storage at room temperature. Loracarbef, like all b-lactams and cephalosporins, inhibits penicillin binding proteins, enzymes that create the cross-linkage of the peptidoglycan polymer. This binding leads to interference with the formation and remodeling of the cell wall structure. Drug type: Approved. Small Molecule. Drug category: Anti-Bacterial Agents. Anti-Infective Agents.

| Loratadine | A second-generation histamine H1 receptor antagonist used in the treatment of allergic rhinitis and urticaria. Unlike most classical antihistamines (histamine H1 antagonists) it lacks central nervous system depressing effects such as drowsiness. (PubChem) Pharmacology: Loratadine, a non-sedating H1-blocker similar in structure to cyproheptadine and azatadine, is used to treat seasonal allergic rhinitis. Unlike other H1-blockers, loratidine does not penetrate the CNS effectively and has a low affinity for CNS H1-receptors. Mechanism of action: Like other H1-blockers, loratadine competes with free histamine for binding at H1-receptors in the GI tract, uterus, large blood vessels, and bronchial muscle. Loratadine also has a weak affinity for acetylcholine and alpha-adrenergic receptors. Drug type: Approved. Small Molecule. Drug category: Anti-Allergic Agents. Antihistamines. Antipruritics.

| Lorazepam | A benzodiazepine used as an anti-anxiety agent with few side effects. It also has hypnotic, anticonvulsant, and considerable sedative properties and has been proposed as a preanesthetic agent. (PubChem) Pharmacology: Lorazepam, a benzodiazepine not transformed to active metabolites, is used to treat anxiety, status epilepticus, and for sedation induction and anterograde amnesia. Mechanism of action: Lorazepam binds to central benzodiazepine receptors which interact allosterically with GABA receptors. This potentiates the effects of the inhibitory neurotransmitter GABA, increasing the inhibition of the ascending reticular activating system and blocking the cortical and limbic arousal that occurs following stimulation of the reticular pathways. Drug type: Approved. Small Molecule. Drug category: Anti-anxiety Agents. Anticonvulsants. Antiemetics. Benzodiazepines. GABA Modulators.

| Lormetazepam | A 1,4-benzodiazepinone compound having a methyl substituent at the 1-position, a hydroxy substituent at the 3-position, a 2-chlorpophenyl group at the 5-position and a chloro substituent at the 7-position. | ILX:0106367 | 3 | FDI Lab - SciCrunch.org | 06/18/2018 | FDI Lab - SciCrunch.org | term | 12/08/2016 | 0 | NeuroLex | NeuroLex |
| Losartan | An antagonist of angiotensin type 1 receptor with antihypertensive activity due to the reduced pressor effect of angiotensin II. (PubChem) Pharmacology: Losartan is the first of a class of antihypertensive agents called angiotensin II (AG II) receptor antagonists. It is, along with its longer acting active metabolite (E-3174), a specific and selective AT1 receptor antagonist. Losartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor found in many tissues, (e.g., vascular smooth muscle, adrenal gland). Mechanism of action: Losartan and its longer acting active metabolite (E-3174) interfere with the binding of angiotensin II to the angiotensin II AT1-receptor by, themselves, binding reversibly to the receptors in vascular smooth muscle and the adrenal gland. As angiotensin II is a vasoconstrictor, which also stimulates the synthesis and release of aldosterone, blockage of its effects results in decreases in systemic vascular resistance. Neither Losartan or its metabolite inhibit the angiotensin converting enzyme, other hormone receptors, or ion channels. Drug type: Approved. Small Molecule. Drug category: Angiotensin II Receptor Antagonists. Angiotensin II Type 1 Receptor Blockers. Anti-Arrhythmia Agents. Antiarrhythmic Agents.

| Loteprednol | Loteprednol (as Loteprednol Etabonate) is a topical corticoid antiinflammatory. It is used in ophthalmic solution for the treatment of steroid responsive inflammatory conditions of the eye such as allergic conjunctivitis, uveitis, acne rosacea, superficial punctate keratitis, herpes zoster keratitis, iritis, cyclitis, and selected infective conjunctivitides. As a nasal spray, is used for the treatment and management of seasonal allergic rhinitis. Pharmacology: Loteprednol etabonate (LE) is a "soft" steroid belonging to a unique class of glucocorticoids. LE possesses a metabolically labile 17 beta-chloromethyl ester function which was designed in order to be hydrolyzed to an inactive carboxylic acid moiety. This inactive metabolite is more hydrophilic and is thus readily eliminated from the body. Loteprednol etabonate has good ocular permeation properties and good skin permeation properties similar to "hard" steroids. It is used as a topical agent for the treatment of steroid responsive inflammatory conditions of the eye such as allergic conjunctivitis, uveitis and iritis. Mechanism of action: Loteprednol etabonate (LE) is a "soft" steroid belonging to a unique class of glucocorticoids. Loteprednol etabonate is structurally similar to other glucocorticoids. However, the number 20 position ketone group is absent. It is highly lipid soluble which enhances its penetration into cells. Loteprednol etabonate is synthesized through structural modifications of prednisolone- related compounds so that it will undergo a predictable transformation to an inactive metabolite. It is a competitive inhibitor of the type II glucocorticoid receptor. Corticosteroids inhibit the inflammatory response to a variety of inciting agents and probably delay or slow healing. They inhibit the edema, fibrin deposition, capillary dilation, leukocyte migration, capillary proliferation, fibroblast proliferation, deposition of collagen, and scar formation associated with inflammation. There is no generally accepted explanation for the mechanism of action of ocular corticosteroids. However, corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2. Drug type: Small Molecule. Drug category: Anti-Allergic Agents.

| Lovastatin | A fungal metabolite isolated from cultures of Aspergillus terreus. The compound is a potent anticholesteremic agent. It inhibits 3-hydroxy-3-methylglutaryl coenzyme A reductase (hydroxymethylglutaryl COA reductases), which is the rate-limiting enzyme in cholesterol biosynthesis. It also stimulates the production of low-density lipoprotein receptors in the liver. (PubChem) Pharmacology: Lovastatin, an antilipemic agent produced by fermentation of Aspergillus terreus, is the first of a class of lipid-lowering agents known as the HMG-CoA reductase inhibitors. Lovastatin is used to treat hypercholesterolemia, to slow coronary atherosclerosis, and to prevent myocardial infarction and stroke. Lovastatin, like simvastin and unlike pravastatin, is a prodrug, concentrating active drug in the liver during first-pass circulation. Mechanism of action: Lovastatin is a lactone that is readily hydrolyzed in vivo to the corresponding b-hydroxyacid, a potent inhibitor of HMG-CoA reductase, the enzyme that catalyzes the conversion of HMG-CoA to mevalonate. The conversion of HMG-CoA to mevalonate is an early step in the biosynthetic pathway for cholesterol. Drug type: Approved. Investigational. Small Molecule. Drug category: Anticholesteremic Agents. Antineoplastic Agents. HMG-CoA Reductase Inhibitors.
