Persistent activation of N-methyl-D-aspartate (NMDA) receptors in Central Nervous System by the excitatory amino acid glutamate has been hypothesized to contribute to the symptomatology of Alzheimer's disease. Memantine is postulated to exert its the...
Metformin is a biguanide type oral antihyperglycemic drug used in the management of type 2 diabetes. It lowers both basal and postprandial plasma glucose. Its mechanism of action is different from those of sulfonylureas and it does not produce hypogl...
Pioglitazone depends on the presence of insulin for its mechanism of action. Pioglitazone decreases insulin resistance in the periphery and in the liver resulting in increased insulindependent glucose disposal and decreased hepatic g...
This tablet combines two antihyperglycemic agents with complementary mechanisms of action to improve glycemic control in patients with type 2 diabetes. Sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, and Metformin HCl, a member of the biguan...
Vildagliptin acts primarily by inhibiting DPP-4 (Dipeptidyl peptidase-4), the enzyme responsible for the degradation of the incretin hormones GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). The administration o...
methylphenidate (MPH) has been shown to act as a norepinephrine and dopamine reuptake inhibitor (NDRI), thereby increasing the presence of these neurotransmitters in the extraneuronal space and prolonging their action. There is a dose-related effect...
Methylprednisolone, a naturally occurring glucocorticoid (hydrocortisone and cortisone), which has also salt-retaining properties, is used as replacement therapy in adrenocortical deficiency states. This synthetic analog is primarily used for its pot...
Metoclopramide blocks dopamine receptors and in higher doses, it also blocks serotonin receptors in chemoreceptor trigger zone of the CNS. It enhances the response to acetylcholine of tissue in upper GI tract causing enhanced motility and accelerated...
Milnacipran is a potent inhibitor of neuronal norepinephrine and serotonin reuptake. It inhibits norepinephrine uptake with approx 3-fold higher potency in vitro than serotonin with directly affecting the uptake of dopamine or other neurotransmitters...
Moxifloxacin is a 4th generation synthetic broad spectrum, fluoroquinolone class of antibacterial drug. It has activity against a wide range of gram-positive, gram-negative, anaerobic and atypical bacteria including Mycoplasma pneumoniae. It acts by...
Nandrolone Decanoate is an injectable anabolic preparation. The pharmacologically active substance is nandrolone. The decanoate ester gives the preparation duration of action of about three weeks after injection. Nandrolone Decanoate is chemically re...
Nebivolol is a β adrenergic receptor blocking agent. Nebivolol inhibits both β1 and β1 adrenergic receptors. Nebivolol lacks intrinsic sympathomimetic and membrane stabilizing activity at therapeutically relevant concentrations. At cli...
Nefopam Hydrochloride is a centrally acting analgesic with a rapid onset of action. The main site of action appears to be in the central nervous system both at the brain and spinal levels. In vitro experiments have shown Nefopam to inhibit the re-upt...
Olopatadine, an antihistamine, works by blocking the action of histamine in the body, which reduces allergy symptoms. Olopatadine hydrochloride treats sneezing, itching, runny nose, and other nasal symptoms of allergies.
Mode of Ac...
Oxybuprocaine is a local anaesthetic. It may be less irritating than tetracaine, and the onset and duration of action are similar to tetracaine. Oxybuprocaine binds to sodium channel and reversibly stabilizes the neuronal membrane which decreases its...
Oxymetazoline Hydrochloride is an imidazoline derivative sympathomimetic amine. It is a direct agonist at α-adrenoceptors but has no action on β- adrenoceptors. It is used as a topical agent on the nasal mucosa, produces a rapid and long a...
Oxymorphone is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxymorphone is analgesia. Like all full opioid agonists,...
Oxyphencyclimine binds the muscarinic acetylcholine receptor. It may block all three types of muscarinic receptors including M-1 receptors in the CNS and ganglia, M-2 receptors in the heart (vagus) and M-3 receptors at the parasympathetic NEJ system....
Paracetamol has analgesic and antipyretic properties with weak anti-inflammatory activity. Paracetamol (Acetaminophen) is thought to act primarily in the CNS, increasing the pain threshold by inhibiting both isoforms of cyclooxygenase, COX-1, COX-2,...
The efficacy of Paroxetine is presumed to be linked to potentiation of serotonergic activity in the central nervous system resulting from inhibition of neuronal reuptake of serotonin (5-hydroxy-tryptamine, 5 HT). Studies at clinically relevant doses...
