Folic acid tablets

My sister is pregnant and the doctor has given her vitamin folic acid tablets to take. My grandmother is 84 and very absent-minded and the doctor has also given her folic acid tablets. She is not pregnant. My father, who recently had a mild heart attack, was also prescribed some foliate tablets. Why has the doctor given all three similar tablets ...

Phenytoin decreases folic add absorption, but folic acid replacement enhances phenytoin clearance and can result in loss of efficacy. Phenytoin tablets and suspension contain phenytoin acid, while the capsules and parenteral solution are phenytoin sodium, which is 92% phenytoin. Clinicians should remember that there are two different strengths of phenytoin suspension and capsules. 

Part—IV has been entirely devoted to various Optical Methods that find their legitimate recognition in the arsenal of pharmaceutical analytical techniques and have been spread over nine chapters. Refractometry (Chapter 18) deals with refractive index, refractivity, critical micelle concentration (CMC) of various important substances. Polarimetry (Chapter 19) describes optical rotation and specific optical rotation of important pharmaceutical substances. Nephelometry and turbidimetry (Chapter 20) have been treated with sufficient detail with typical examples of chloroetracyclin, sulphate and phosphate ions. Ultraviolet and absorption spectrophotometry (Chapter 21) have been discussed with adequate depth and with regard to various vital theoretical considerations, single-beam and double-beam spectrophotometers besides typical examples amoxycillin trihydrate, folic acid, glyceryl trinitrate tablets and stilbosterol. Infrared spectrophotometry (IR) (Chapter 22) essentially deals with a brief introduction of group-frequency... 

The SP procedure of water-soluble vitamins from multivitamin tablets is particularly challenging due to the diverse analytes of varied hydrophobicities and pfC. Water-soluble vitamins (WSVs) include ascorbic acid (vitamin C), niacin, niacinamide, pyridoxine (vitamin B ), thiamine (vitamin Bj), folic acid, riboflavin (vitamin B2) and others. While most WSVs are highly water soluble, riboflavin is quite hydrophobic and insoluble in water. Folic acid is acidic while pyridoxine and thiamine are basic. In addition, ascorbic acid is light sensitive and easily oxidized. The extraction strategy employed was a two-step approach using mixed solvents of different polarity and acidity as follows ... 

Water-soluble vitamins in formulations have been determined by use of ion-pair chromatography. The vitamins include several B vitamins as well as niacin, folic acid, and ascorbic acid (565). Vitamins D and Da were rapidly separated on reverse phase columns (247) as are vitamins A, D, and E in multivitamin tablets (564). Addition of silver ions to the mobile phase has been shown to increase the flexibility inherent in RPC by complexing with the unsaturated bonds and thereby decreasing the retention factor. This effect is also observed with other unsaturated drug molecules including steroids (247). Vitamin A and related compounds have... 

Dietary supplements are products taken by mouth that contain an ingredient intended to supplement the diet, such as vitamins, minerals, herbs or other botanicals, amino acids, and substances such as enzymes, organ tissues, and metabolites. Dietary supplements come in many forms, including extracts, concentrates, tablets, capsules, gel caps, liquids, and powders. They have special requirements for labeling. In the U.S., the Dietary Supplement Health and Education Act of 1994 states that dietary supplements are considered foods, not drugs. (Note that some dietary supplements are used in conventional medicine for example, folic acid... 

Folacin bioavailability varies among the vitamers (120,125). Folic acid is more readily available than the naturally occurring food folates but may be less available from fortified foods than in aqueous solution or tablet form. Food folates have been reported to be 30-80% as available as folic acid. Folacin availability, absorption, and metabolism were recently reviewed (20,120,122). 

An interesting example is die assay of clonidine hydrochloride in injections and tablets (British Pharmacopoeia, 1980). In 0.01 Mhydrochloric acid, clonidine exhibits two sharp maxima ne - 272 nm and 279 nm, which are not suitable for precise measurement. However, clonidine forms an ion pair with bromothymol blue, and this can be readily extracted into chloroform for subsequent measurement of the broad maximum near 420 nm. Because of the intiinsic variabihty of reagents used in such methods, a pharmacopoeial reference standard is employed for cahbration. A similar policy is adopted for assays involving chemical modification of the drug, as in the tetrazolium assay for corticosteroids, the assay for folic acid involving hydrolysis, diazotisation, and coupling with N-(l-naphthyl)ethylenediamine, and the reaction of penicillins with imidazole and mercuric salts. 

Pyrimethamine acts synergistically with suifadoxine (as Fansidar) to inhibit folic acid metabolism (see antifols, above) suifadoxine is excreted in the urine. The combination is chiefly used with quinine to treat acute attacks of malaria caused by susceptible strains of Plasmodium falciparum a single dose of pyrimethamine 75 mg plus suifadoxine 1.5 g (3 tablets) usually suffices. 

Pregnancy. The extra iron required by mother and fetus totals 1000 mg, chiefly in the latter half of pregnancy. The fetus takes iron from the mother even if she is iron deficient. Dietary iron is seldom adequate and iron and folic acid (50-100 mg elemental iron plus folic acid 200-500 micrograms/day) should be given to pregnant women from the fourth month. Opinions differ on whether all women should receive prophylaxis or only those who can be identified as needing it. There are numerous formulations. Parents should be particularly warned not to let children get at the tablets.

It s best to take SAMe with vitamins Bs, B, folic acid, magnesium, and calcium. These help it work better and reduce any side-effect risks. Because this supplement is highly unstable, buy it in the form of enteric-coated tablets stored in foil packets and keep the pills in the foil until just before you take them.

Pyroxidine, thiamin hydrochloride, cyanocobalamin, and folic acid from tablets were resolved on a 35°C ) -cyclodextrin column, (A = 254nm) using a 20/80 methanol/water (50 mM phosphate buffer pH 7) mobile phase [331], Elution was complete in <7 min. Peaks shapes were somewhat broad. A lower pH and a more concentrated buffer would most likely help correct this problem. 

Graphene modified with a selection of porphyrins and phthalocyanines was tested for the analysis of folic acid in pharmaceutical tablets [135].
