Cholecalciferol is a steroid hormone produced in the skin when exposed to ultraviolet light or obtained from dietary sources. The active form of cholecalciferol, 1,25-dihydroxycholecalciferol (calcitriol) plays an important role in maintaining blood calcium and phosphorus levels and mineralization of bone. The activated form of cholecalciferol binds to vitamin D Read More …

Aripiprazole is a quinoline derivate and atypical antipsychotic agent. Aripiprazole has partial agonistic activity at dopamine D2 receptors and serotonin 5-HT1A receptors, as well as potent antagonistic activity on serotonin 5-HT2A receptors. This drug stabilizes dopamine and serotonin activity in the limbic and cortical system. Aripiprazole is used in managing symptoms of schizophrenia and of acute manic Read More …

Ziprasidone Hydrochloride is the hydrochloride salt form of ziprasidone, a benzothiazolylpiperazine derivative and an atypical antipsychotic agent with an antischizophrenic property. Ziprasidone hydrochloride functions as an antagonist at the dopamine D2 and serotonin 5-HT2A and 5-HT1D receptors, and as an agonist at the 5-HT1A receptor. Ziprasidone hydrochloride also inhibits synaptic reuptake Read More …

Risperidone is a benzisoxazole derivative with the antipsychotic property. Risperidone selectively antagonizes serotonin (5-HT) effects via the cortical 5-HT2 receptor, and, to a lesser extent, competes with dopamine at the limbic dopamine D2 receptor. The antagonism leads to decreased psychotic effects, such as hallucinations and delusions. In addition, risperidone has low to moderate Read More …

Clozapine is a synthetic dibenzo-diazepine derivative, atypical antipsychotic Clozapine blocks several neurotransmitter receptors in the brain (dopamine type 4, serotonin type 2, norepinephrine, acetylcholine, and histamine receptors). Unlike traditional antipsychotic agents, it weakly blocks dopamine type 2 receptors. It relieves schizophrenic symptoms (hallucinations, delusions, dementia). or Clozapine is a tricyclic dibenzodiazepine, classified Read More …

Glycopyrrolate is a medication of the muscarinic anticholinergic group. It does not cross the blood-brain barrier and consequently has no to few central effects. A synthetic quaternary amine, it is available in oral and intravenous forms and as inhalation. It was developed by Sosei and licensed to Novartis in 2005. The cation, Read More …

Umeclidinium is a long-acting muscarinic antagonist (LAMA) used as maintenance treatment for symptoms of chronic obstructive pulmonary disease (COPD). It is available as a once-daily inhalation monotherapy or as a fixed-dose combination product with the long-acting beta2-agonist vilanterol. COPD is a progressive Read More …

Olodaterol is a novel, long-acting beta2-adrenergic agonist (LABA) that exerts its pharmacological effect by binding and activating beta2-adrenergic receptors located primarily in the lungs. Beta2-adrenergic receptors are membrane-bound receptors that are normally activated by endogenous epinephrine whose signaling, via a downstream L-type calcium channel interaction, Read More …

Arformoterol is a beta2-Adrenergic Agonist. The mechanism of action of arformoterol is as an Adrenergic beta2-Agonist. Formoterol is a long-acting beta-adrenergic receptor agonist with bronchodilator activity. Formoterol selectively binds to beta-2 adrenergic receptors in bronchial smooth muscle, thereby activating intracellular adenyl cyclase, an enzyme that catalyzes Read More …

Indacaterol is a novel, ultra-long-acting, (2)-adrenoceptor agonist developed for Novartis for the once-daily treatment of asthma and chronic obstructive pulmonary disease. It was approved by the European Medicines Agency (EMA) under the trade name Onbrez on November 30, 2009, and by the United Read More …

Pirbuterol is a short-acting, beta-adrenergic receptor agonist with bronchodilator activity. Pirbuterol selectively binds to beta-2 adrenergic receptors in bronchial smooth muscle, thereby activating intracellular adenyl cyclase, an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3′,5′-adenosine monophosphate (cAMP). Increased cAMP levels cause relaxation of the Read More …

Levosalbutamol/Levalbuterol also known as levalbuterol is a short-acting β2 adrenergic receptor agonist used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). Salbutamol has been marketed as a racemic mixture, although beta2-agonist activity resides almost exclusively in the (R)-enantiomer. The enantioselective disposition of salbutamol and the possibility that Read More …
