Acidifiers
Acidifiers are inorganic chemicals that, put into a human (or other mammalian) body, either produce or become acid. These chemicals increase the level of gastric acid in the stomach when ingested, thus decreasing the stomach pH. Out of many types of acidifiers, the main four are: * Gastric acidifiers, these are the drugs which are used to restore temporarily the acidity of stomach in patient suffering from hypochlorhydria * Urinary acidifiers, used to control pH in urine * Systemic acidifiers, used to control pH in the overall body * Acids, mostly used in laboratory experiments Acidifier performance in distal stomach is debatable. Patients who suffer from achlorhydria have deficient secretion of hydrochloric acid in their stomach. In such cases, acidifiers may provide sufficient acidity for proper digestion of food. Systemic acidifiers, usually given by injection, act by reducing the alkali reserve in the body, and are also useful in reducing metabolic alkalosis.Text Book of Pha ...

Sodium Bicarbonate
Sodium bicarbonate ( IUPAC name: sodium hydrogencarbonate), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation ( Na+) and a bicarbonate anion ( HCO3−). Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs. Nomenclature Because it has long been known and widely used, the salt has many different names such as baking soda, bread soda, cooking soda, and bicarbonate of soda and can often be found near baking powder in stores. The term ''baking soda'' is more common in the United States, while ''bicarbonate of soda'' is more common in Australia, United Kingdom and Ireland. and in many northern/central European countries it is called ...

Udenafil
The drug udenafil is marketed under the trade name Zydena. It is within the PDE5 inhibitor class (which also includes avanafil, sildenafil, tadalafil, and vardenafil). Like other PDE5 inhibitors, it is used to treat erectile dysfunction. Udenafil was developed by Dong-A Pharmaceutical. It has fairly rapid onset of action (peak plasma concentration after 1 to 1.5 hours), and has long duration of action (plasma half-life of 11 to 13 hours). Udenafil's pharmacokinetics allows once-daily dosage (in addition to on-demand use). Typical doses are 100 and 200 mg. Udenafil is available in Korea, Russia, and the Philippines. It has not yet been approved for use in the United States by the U.S. Food and Drug Administration The United States Food and Drug Administration (FDA or US FDA) is a federal agency of the Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food .... Refere ...

Avanafil
Avanafil is a PDE5 inhibitor approved for erectile dysfunction by the FDA on April 27, 2012 and by EMA on June 21, 2013. Avanafil is sold under the brand names Stendra and Spedra. It was invented at Mitsubishi Tanabe Pharma, formerly known as Tanabe Seiyaku Co., and licensed to Vivus Inc., which partnered with Menarini Group to commercialise Spedra in over forty European countries, Australia, and New Zealand. Metuchen Pharmaceuticals obtained exclusive rights within the United States. Avanafil acts by inhibiting a specific phosphodiesterase type 5 enzyme found in various body tissues, primarily in the corpus cavernosum penis. Other similar drugs are sildenafil, tadalafil and vardenafil. The advantage of avanafil is that it has very fast onset of action compared with other PDE5 inhibitors. It is absorbed quickly, reaching a maximum serum concentration in about thirty to forty-five minutes. About two-thirds of the participants were able to engage in sexual activity within fift ...

Vardenafil
Vardenafil is a PDE5 inhibitor used for treating erectile dysfunction that is sold under the brand name Levitra among others. Medical use Vardenafil's indications and contraindications are the same as with other PDE5 inhibitors; it is closely related in function to sildenafil citrate (Viagra) and tadalafil (Cialis). The difference between the vardenafil molecule and sildenafil citrate is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both sildenafil and vardenafil. Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's. Vardenafil also does not have an effect on PDE6, which means that it does not have vision adverse effects. Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where it may significantly increase the time from penetration to ejaculation.

Tadalafil
Tadalafil, sold under the brand name Cialis among others, is a medication used to treat erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension. It is taken by mouth. Onset is typically within half an hour and the duration is up to 36 hours. Common side effects include headache, muscle pain, flushed skin, and nausea. Caution is advised in those with cardiovascular disease. Rare but serious side effects include a prolonged erection that can lead to damage to the penis, vision problems, and hearing loss. Tadalafil is not recommended in people taking nitrovasodilators such as nitroglycerin, as this may result in a serious drop in blood pressure. Tadalafil is a PDE5 inhibitor which increases blood flow to the penis. It also dilates blood vessels in the lungs, which lowers the pulmonary artery pressure. Tadalafil was approved for medical use in the United States in 2003. It is available as a generic medication. In 2020, it was the 26 ...

Apomorphine
Apomorphine, sold under the brand name Apokyn among others, is a type of aporphine having activity as a non- selective dopamine agonist which activates both D2-like and, to a much lesser extent, D1-like receptors. It also acts as an antagonist of 5-HT2 and α-adrenergic receptors with high affinity. The compound is historically a morphine decomposition product made by boiling morphine with concentrated acid, hence the ''-morphine'' suffix. Contrary to its name, apomorphine does not actually contain morphine or its skeleton, nor does it bind to opioid receptors. The ''apo-'' prefix relates to it being a morphine derivative (" omesfrom morphine"). Historically, apomorphine has been tried for a variety of uses, including as a way to relieve anxiety and craving in alcoholics, an emetic (to induce vomiting), for treating stereotypies (repeated behaviour) in farmyard animals, and more recently in treating erectile dysfunction. Currently, apomorphine is used in the treatment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moxisylyte
Moxisylyte, also known as thymoxamine, is a drug used in urology for the treatment of erectile dysfunction. It is an α1-adrenergic antagonist. In the United Kingdom, Moxisylte is marketed as Opilon (Archimedes Pharma UK Ltd) and is used for the short-term treatment of primary Raynaud's syndrome Raynaud syndrome, also known as Raynaud's phenomenon, eponymously named after the physician Auguste Gabriel Maurice Raynaud, who first described it in his doctoral thesis in 1862, is a medical condition in which the spasm of small arteries cau .... This is a condition where the fingers and toes become discoloured and is triggered by responses to cold, or emotional distress. Opilon tablets help by improving blood circulation to the extremities.

Phentolamine
Phentolamine, sold under the brand name Regitine among others, is a reversible nonselective α- adrenergic antagonist. Mechanism Its primary action is vasodilation due to α1 blockade. Non-selective α-blockers can cause a much more pronounced reflex tachycardia than the selective α1 blockers. Like the selective α1 blockers, phentolamine causes a relaxation of systemic vasculature, leading to hypotension. This hypotension is sensed by the baroreceptor reflex, which results in increased sympathetic nerve firing on the heart, releasing norepinephrine. In response, the β1 adrenergic receptors on the heart increase their rate, contractility, and dromotropy, which help to offset the decrease in systemic blood pressure. Unlike the α1 selective blockers, phentolamine also inhibits the α2 receptors, which function predominantly as presynaptic negative feedback for norepinephrine release. By abolishing this negative feedback phentolamine leads to even less regulated norepinephr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yohimbin
Yohimbine (), also known as quebrachine, is an indole alkaloid derived from the bark of the African tree ''Pausinystalia johimbe''; also from the bark of the unrelated South American tree ''Aspidosperma quebracho-blanco''. Yohimbine is an α2-adrenergic receptor antagonist, and has been used in a variety of research projects. It is a veterinary drug used to reverse sedation in dogs and deer. While yohimbine behaves as an aphrodisiac in some mammals, it does not do so in humans. It has been prescribed as a treatment for erectile dysfunction, although its reported clinical benefits were modest and it has largely been superseded by the PDE5 inhibitor class of drugs. Substances that have purported to be extracts from the yohimbe tree have been marketed as dietary supplements for various purposes, but they contain highly variable amounts of yohimbine, if any; no published scientific evidence supports their efficacy. Uses Yohimbine is a drug used in veterinary medicine to reverse t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sildenafil
Sildenafil, sold under the brand name Viagra, among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. It is unclear if it is effective for treating sexual dysfunction in women. It is taken by mouth or by injection into a vein. Onset is typically within twenty minutes and lasts for about two hours. Common side effects include headaches, heartburn, and flushed skin. Caution is advised in those with cardiovascular disease. Rare but serious side effects include a prolonged erection (priapism) that can lead to damage to the penis, vision problems, and hearing loss. Sildenafil should not be taken by people on nitrates such as nitroglycerin (glycerin trinitrate), as this may result in a serious drop in blood pressure. Sildenafil should not be taken within four hours of taking an alpha blocker. Sildenafil acts by blocking phosphodiesterase 5 (PDE5), an enzyme that promotes breakdown of cGMP, which regulates blood flow in the p ...
