Nitazoxanide

Nitazoxanide is a broad-spectrum antiparasitic and broad-spectrum antiviral drug that is used in medicine for the treatment of various helminthic, protozoal, and viral infections. It is indicated for the treatment of infection by Cryptosporidium parvum and Giardia lamblia in immunocompetent individuals and has been repurposed for the treatment of influenza. Nitazoxanide has also been shown to have in vitro antiparasitic activity and clinical treatment efficacy for infections caused by other protozoa and helminths; emerging evidence suggests that it possesses efficacy in treating a number of viral infections as well.

Chemically, nitazoxanide is the prototype member of the thiazolides, a class of drugs which are synthetic nitrothiazolyl-salicylamide derivatives with antiparasitic and antiviral activity. Tizoxanide, an active metabolite of nitazoxanide in humans, is also an antiparasitic drug of the thiazolide class.

Valdecoxib

Valdecoxib is a non-steroidal anti-inflammatory drug (NSAID) used in the treatment of osteoarthritis, rheumatoid arthritis, and painful menstruation and menstrual symptoms. It is a selective cyclooxygenase-2 inhibitor.

 

Valdecoxib was manufactured and marketed under the brand name Bextra by G. D. Searle & Company as an anti-inflammatory arthritis drug. It was approved by the United States Food and Drug Administration on November 20, 2001, to treat arthritis and menstrual cramps. and was available by prescription in tablet form until 2005 when the FDA requested that Pfizer withdraw Bextra from the American market. The FDA cited "potential increased risk for serious cardiovascular (CV) adverse events," an "increased risk of serious skin reactions" and the "fact that Bextra has not been shown to offer any unique advantages over the other available NSAIDs."

Testosterone enanthate

Testosterone enanthate (USAN, BAN) (brand names Delatestryl, Testostroval, Testro LA, Andro LA, Durathate, Everone, Testrin, Andropository), or testosterone heptanoate, is an androgen and anabolic steroid and a testosterone ester. Along with testosterone cypionate and testosterone propionate, it is one of the most widely used testosterone esters. Testosterone enanthate was first introduced in 1952. Administered via intramuscular injection, it is the most widely used form of testosterone in androgen replacement therapy.

Testosterone enanthate has an elimination half-life of 4.5 days and a mean residence time of 8.5 days when used as a depot intramuscular injection. It requires frequent administration of approximately once per week, and large fluctuations in testosterone levels result with it, with levels initially being elevated and supraphysiological.

Applications:

There is no one "standard" dosage for testosterone enanthate. Your healthcare provider will essentially guess at an appropriate starting amount, based on your age, diagnosis, and testosterone levels. From there, your healthcare provider will adjust your dose as needed, based on how you react to the medication (how your testosterone levels change and how your symptoms improve).

The normal dosing range for this medication is 50 to 400 mg given every two to four weeks, although there are certainly plenty of individuals who end up needing a higher or lower amount.

To start puberty in adolescent males, various dosage regimens have been suggested. Some healthcare providers like to start with a low dosage and gradually work up to a higher one. Others prefer to start with a high amount, lowering it once puberty is under way.

For treating women with breast cancer, standard dosages range from 200 to 400 mg every two to four weeks.

The medication is an injection that is given once every two to four weeks. It is typically given into the gluteal muscle.

Some people are able to give themselves the injections. Others have a friend or family member give it.Others only feel comfortable with a healthcare provider giving the injection.

Quercetin

Quercetin is a plant polyphenol from the flavonoid group, found in many fruits, vegetables, leaves, and grains. It can be used as an ingredient in supplements, beverages, or foods.

Clinical research

 

Although quercetin is under basic and early-stage clinical research for a variety of disease conditions, there is insufficient evidence on whether quercetin promotes DNA repair in humans. Claims about the role of quercetin in liver and kidney system function, mental performance or cardiovascular health in the human body are insufficiently defined to draw any conclusions. The US FDA has issued warning letters to emphasize that quercetin is not a defined nutrient nor an antioxidant, cannot be assigned a dietary content level, and is not regulated as a drug to treat any human disease.

Levothyroxine

Levothyroxine, also known as L-thyroxine, is a manufactured form of the thyroid hormone, thyroxine (T4). It is used to treat thyroid hormone deficiency including the severe form known as myxedema coma. It may also be used to treat and prevent certain types of thyroid tumors. It is not indicated for weight loss. Levothyroxine is taken by mouth or given by injection into a vein. Maximum effect from a specific dose can take up to six weeks to occur.
Side effects from excessive doses include weight loss, trouble tolerating heat, sweating, anxiety, trouble sleeping, tremor, and fast heart rate. Use is not recommended in people who have had a recent heart attack. Use during pregnancy has been found to be safe. It is recommended that dosing be based on regular measurements of TSH and T4 levels in the blood. Much of the effect of levothyroxine is following its conversion to triiodothyronine (T3).

Dihydrotestosterone (DHT)

Dihydrotestosterone (DHT), or 5α-dihydrotestosterone (5α-DHT), also known as 5α-androstan-17β-ol-3-one, is an endogenous androgen sex steroid and hormone. The enzyme 5α-reductase catalyzes the formation of DHT from testosterone in certain tissues including the prostate gland, seminal vesicles, epididymides, skin, hair follicles, liver, and brain. This enzyme mediates reduction of the C4-5 double bond of testosterone. Relative to testosterone, DHT is considerably more potent as an agonist of the androgen receptor (AR).

Methocarbamol

Methocarbamol is a central muscle relaxant used to treat skeletal muscle spasms. Under the trade name Robaxin, it is marketed by Actient Pharmaceuticals in the United States and Pfizer in Canada. The mechanism of action of methocarbamol is currently unknown, but may involve the inhibition of carbonic anhydrase. The muscle relaxant effects of methocarbamol are largely attributed to central depressant effects; however, peripheral effects of methocarbamol to prolong muscle refractory period have also been reported.

Metabolism

 

Methocarbamol is the carbamate of guaifenesin, but does not produce guaifenesin as a metabolite, because the carbamate bond is not hydrolyzed metabolically; metabolism is by Phase I ring hydroxylation and O-demethylation, followed by Phase II conjugation. All the major metabolites are unhydrolyzed carbamates.

Amlodipine

Amlodipine, sold under the brand name Norvasc among others, is a medication used to treat high blood pressure and coronary artery disease. While calcium channel blockers are not typically recommended in heart failure, amlodipine may be used if other medications are not sufficient for high blood pressure or heart related chest pain. Amlodipine is taken by mouth and has an effect for at least a day.

 

Common side effects include: swelling, feeling tired, abdominal pain, and nausea. Serious side effects may include low blood pressure or a heart attack. It is unclear if use is safe during pregnancy or breastfeeding. Doses should be decreased in people with liver problems and those who are old. Amlodipine is a long acting calcium channel blocker of the dihydropyridine type. It works partly by increasing the size of arteries.

 

Medical uses

Amlodipine is used in the management of hypertension[7] and coronary artery disease (chronic stable angina, vasospastic angina, and angiographically documented CAD without heart failure or ejection fraction < 40%.) It can be used as either monotherapy or combination therapy for the management of hypertension or coronary artery disease. Amlodipine can be administered to adults and children 6–17 years of age.

Dehydroepiandrosterone (DHEA)

Dehydroepiandrosterone (DHEA), also known as androstenolone or as prasterone (INN), is an endogenous steroid hormone. It is one of the most abundant circulating steroids in humans, in whom it is produced in the adrenal glands, the gonads, and the brain, where it functions as a metabolic intermediate in the biosynthesis of the androgen and estrogen sex steroids. However, DHEA also has a variety of potential biological effects in its own right, binding to an array of nuclear and cell surface receptors, and acting as a neurosteroid and neurotrophin. DHEA is also used orally as a medication and dietary supplement, to restore or increase DHEA and DHEA sulfate (DHEA-S) levels.

Application: For the synthesis of steroid hormone drugs.
Dehydroepiandrosterone acetate is an important intermediate for the synthesis of various hormones, family planning supplies and other steroid hormones. Also used as an important intermediate for the synthesis of testosterone, methyl testosterone, β -estradiol, Estriol.

Pregnenolone

Pregnenolone is a natural hormone that cannot be patented. Back in the 1940's, when researchers started experimenting with it, they realized that it could be helpful for people under stress and it could increase energy in those who were fatigued. However, about the same time, cortisol, another closely related hormone, was discovered.
