Moclobemide

Moclobemide (sold as Amira, Aurorix, Clobemix, Depnil and Manerix) is a reversible inhibitor of monoamine oxidase A (RIMA) drug primarily used to treat depression and social anxiety. It is not approved for use in the United States, but is approved in other Western countries such as the UK and Australia (TGA approved in December 2000). It is produced by affiliates of the Hoffmann–La Roche pharmaceutical company. Initially, Aurorix was also marketed by Roche in South Africa, but was withdrawn after its patent rights expired and Cipla Medpro's Depnil and Pharma Dynamic's Clorix became available at half the cost. No significant rise in blood pressure occurs when moclobemide is combined with amines such as tyramine-containing foods or pressor amine drugs, unlike with the older nonselective and irreversible monoamine oxidase inhibitors (MAOIs), which cause a severe rise in blood pressure with such combination. Due to the lack of anticholinergic, cardiovascular, cognitive and psychomotor impairments moclobemide is advantageous in the elderly as well as those with cardiovascular disease.

Parietal lobe

The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus. The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation (proprioception), the main sensory receptive area for the sense of touch (mechanoreception) in the somatosensory cortex which is just posterior to the central sulcus in the postcentral gyrus, and the dorsal stream of the visual system. The major sensory inputs from the skin (touch, temperature, and pain receptors), relay through the thalamus to the parietal lobe. Several areas of the parietal lobe are important in language processing. The somatosensory cortex can be illustrated as a distorted figure – the homunculus (Latin: "little man"), in which the body parts are rendered according to how much of the somatosensory cortex is devoted to them.Schacter, D. L., Gilbert, D. L. & Wegner, D. M. (2009). Psychology. (2nd ed.). New York (NY): Worth Publishers. The superior parietal lobule and inferior parietal lobule are the primary areas of body or spacial awareness. A lesion commonly in the right superior or inferior parietal lobule leads to hemineglect. The name comes from the parietal bone, which is named from the Latin paries-, meaning "wall".

Paroxetine

Paroxetine, also known by trade names including Paxil and Seroxat among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It is used to treat major depressive disorder, obsessive-compulsive disorder, social anxiety disorder, panic disorder, posttraumatic stress disorder, generalized anxiety disorder and premenstrual dysphoric disorder. It has also been used in the treatment of hot flashes and night sweats associated with menopause. It has a similar tolerability profile to other SSRIs. The common side effects include drowsiness, dry mouth, loss of appetite, sweating, trouble sleeping and delayed ejaculation. It may also be associated with a slightly increased risk of birth defects. The rate of withdrawal symptoms in young people may be higher with paroxetine and venlafaxine than other SSRIs and SNRIs. Several studies have associated paroxetine with suicidal thinking and behavior in children and adolescents. Marketing of the drug began in 1992 by the pharmaceutical company SmithKline Beecham, known since 2000 as GlaxoSmithKline. Generic formulations have been available since 2003 when the patent expired. The United States Department of Justice fined GlaxoSmithKline $3 billion in 2012, including a sum for withholding data on paroxetine, unlawfully promoting it for under-18s and preparing an article, following one of its clinical trials, study 329, that misleadingly reported the drug was effective in treating adolescent depression.

Propranolol, sold under the brand name Inderal among others, is a medication of the beta blocker type. It is used to treat high blood pressure, a number of types of irregular heart rate, thyrotoxicosis, capillary hemangiomas, performance anxiety, and essential tremors. It is used to prevent migraine headaches, and to prevent further heart problems in those with angina or previous heart attacks. It can be taken by mouth or by injection into a vein. The formulation that is taken by mouth comes in short-acting and long-acting versions. Propranolol appears in the blood after 30 minutes and has a maximum effect between 60 and 90 minutes when taken by mouth. Common side effects include nausea, abdominal pain, and constipation. It should not be used in those with an already slow heart rate and most of those with heart failure. Quickly stopping the medication in those with coronary artery disease may worsen symptoms. It may worsen the symptoms of asthma. Caution is recommended in those with liver or kidney problems. Propranolol may cause harmful effects in the baby if taken during pregnancy. Its use during breastfeeding is probably safe, but the baby should be monitored for side effects. It is a non-selective beta blocker which works by blocking β-adrenergic receptors. Propranolol was discovered in 1964. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. Propranolol is available as a generic medication. The wholesale cost in the developing world is between 0.24 and 2.16 per month as of 2014. In the United States it costs about $15 per month at a typical dose.
