Gabapentin enacarbil (Horizant in USA, Regnite in Japan), is a prodrug of gabapentin, an antiepileptic drug (AED). It was designed for increased oral bioavailability over gabapentin and to be transported through two high capacity transporters in the intestine, sodium-dependent multivitamin transporter (SMVT) and MCT1. It was shown that the prodrug is a substrate for both MCT1 and SMVT. The oral bioavailability of gabapentin following the administration of its prodrug was found to be 84.2% compared with 25.4% after a similar oral dose of gabapentin. Discovered and developed by XenoPort, gabapentin enacarbil was approved in the United States in 2011 for the treatment of moderate-to-severe primary restless legs syndrome (RLS) in adults and in June 2012 for the management of postherpetic neuralgia (PHN) in adults. Therapeutic effects of gabapentin enacarbil in RLS and PHN are attributable to gabapentin. The precise mechanism by which gabapentin is efficacious in RLS and PHN is unknown. In vitro studies have shown that gabapentin binds with high affinity to certain parts of voltage-activated calcium channels in the central nervous system. However, the relationship of this binding to the therapeutic effects of gabapentin enacarbil in RLS and PHN is unknown. The most common adverse reactions for adult patients with moderate-to-severe primary RLS and PHN receiving Horizant were somnolence/sedation, dizziness, headache, nausea and fatigue.

Conditions:
Loratadine is a derivative of azatadine and 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. Loratadine competes with free histamine and exhibits specific, selective peripheral H1 antagonistic activity. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms (eg. nasal congestion, watery eyes) brought on by histamine. Loratadine has low affinity for cholinergic receptors and does not exhibit any appreciable alpha-adrenergic blocking activity in-vitro. Loratadine also appears to suppress the release of histamine and leukotrienes from animal mast cells, and the release of leukotrienes from human lung fragments, although the clinical importance of this is unknown.

Torasemide is a pyridine-sulfonylurea type loop diuretic mainly used for the treatment of edema associated with congestive heart failure, renal disease, or hepatic disease. Also for the treatment of hypertension alone or in combination with other antihypertensive agents. It is also used at low doses for the management of hypertension. It is marketed under the brand name Demadex. Torasemide inhibits the Na+/K+/2Cl--carrier system (via interference of the chloride binding site) in the lumen of the thick ascending portion of the loop of Henle, resulting in a decrease in reabsorption of sodium and chloride. This results in an increase in the rate of delivery of tubular fluid and electrolytes to the distal sites of hydrogen and potassium ion secretion, while plasma volume contraction increases aldosterone production. The increased delivery and high aldosterone levels promote sodium reabsorption at the distal tubules, and by increasing the delivery of sodium to the distal renal tubule, torasemide indirectly increases potassium excretion via the sodium-potassium exchange mechanism. Torasemide's effects in other segments of the nephron have not been demonstrated. Thus torasemide increases the urinary excretion of sodium, chloride, and water, but it does not significantly alter glomerular filtration rate, renal plasma flow, or acid-base balance. Torasemide's effects as a antihypertensive are due to its diuretic actions. By reducing extracellular and plasma fluid volume, blood pressure is reduced temporarily, and cardiac output also decreases.

Felbamate is an antiepileptic indicated as monotherapy or as an adjunct to other anticonvulsants for the treatment of partial seizures resulting from epilepsy. Receptor-binding studies in vitro indicate that felbamate has weak inhibitory effects on GABA-receptor binding, benzodiazepine receptor binding, and is devoid of activity at the MK-801 receptor binding site of the NMDA receptor-ionophore complex. However, felbamate does interact as an antagonist at the strychnine-insensitive glycine recognition site of the NMDA receptor-ionophore complex. The mechanism by which felbamate exerts its anticonvulsant activity is unknown, but in animal test systems designed to detect anticonvulsant activity, felbamate has properties in common with other marketed anticonvulsants. In vitro receptor binding studies suggest that felbamate may be an antagonist at the strychnine-insensitive glycine-recognition site of the N-methyl-D-aspartate (NMDA) receptor-ionophore complex. Antagonism of the NMDA receptor glycine binding site may block the effects of the excitatory amino acids and suppress seizure activity. Animal studies indicate that felbamate may increase the seizure threshold and may decrease seizure spread. It is also indicated that felbamate has weak inhibitory effects on GABA-receptor binding, benzodiazepine receptor binding. Felbamate should be used only in those patients who respond inadequately to alternative treatments and whose epilepsy is so severe that a substantial risk of aplastic anemia and/or liver failure is deemed acceptable in light of the benefits conferred by its use. Felbatol is the brand name used in the United States for felbamate.

Sotalol has both beta-adrenoreceptor blocking and cardiac action potential duration prolongation antiarrhythmic properties. Sotalol inhibits response to adrenergic stimuli by competitively blocking β1-adrenergic receptors within the myocardium and β2-adrenergic receptors within bronchial and vascular smooth muscle. It is FDA approved for the treatment of ventricular arrhythmias, symptomatic atrial fibtillation, symptomatic atriall flutter. Common adverse reactions include bradyarrhythmia, chest pain, lightheadedness, palpitations, rash, nausea, dizziness, headache, dyspnea, fatigue. Proarrhythmic events were more common in sotalol treated patients also receiving digoxin. Sotalol should be administered with caution in conjunction with calcium blocking drugs because of possible additive effects on atrioventricular conduction or ventricular function. Patients treated with sotalol plus a catecholamine depletor should therefore be closely monitored for evidence of hypotension and/or marked bradycardia which may produce syncope.

Cefpodoxime is an orally administered, extended spectrum, semi-synthetic antibiotic of the cephalosporin class. Cefpodoxime is a bactericidal agent that acts by inhibition of bacterial cell wall synthesis. Cefpodoxime has activity in the presence of some beta-lactamases, both penicillinases and cephalosporinases, of Gram-negative and Gram-positive bacteria. Cefpodoxime is indicated for the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions: acute otitis media; pharyngitis and/or tonsillitis; community-acquired pneumonia; acute bacterial exacerbation of chronic bronchitis; gonorrhea; uncomplicated skin and skin structure infections; acute maxillary sinusitis and uncomplicated urinary tract infections (cystitis). Common adverse reactions include diarrhea, nausea, vaginal fungal infections, vulvovaginal infections, abdominal pain, headache. Concomitant administration of high doses of antacids (sodium bicarbonate and aluminum hydroxide) or H2 blockers reduces peak plasma levels by 24% to 42% and the extent of absorption by 27% to 32%, respectively. Oral anti-cholinergics (e.g., propantheline) delay peak plasma levels (47% increase in Tmax), but do not affect the extent of absorption (AUC). Probenecid: As with other beta-lactam antibiotics, renal excretion of cefpodoxime was inhibited by probenecid and resulted in an approximately 31% increase in AUC and 20% increase in peak cefpodoxime plasma levels.

Oxaprozin is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic properties. Anti-inflammatory effects of Oxaprozin are believed to be due to inhibition of cylooxygenase in platelets which leads to the blockage of prostaglandin synthesis. Antipyretic effects may be due to action on the hypothalamus, resulting in an increased peripheral blood flow, vasodilation, and subsequent heat dissipation. Oxaprozin is a non-selective NSAID, with a cell assay system showing lower COX-2 selectivity implying higher COX-1 selectivity. Oxaprozin is used to treat rheumatoid arthritis, osteoarthritis, dysmenorrhea, and to alleviate moderate pain.
