COMPOSITION
Each sugar – coated tablet contains:
Zinc sulfate monohydrate USP - 55mg
Folic Acid BP – 5 mg
Colours ponceau 4R & titanium Dioxide BP
DESCRIPTION:
folinz is a single tablet containing Folic Acid and Zinc, which
makes it an important vitamin nutritional supplement, Zinc is a vital trace
element plying multiple role in the human body. Zinc boosts up immunity,
improves resistance in disease conditions. Zinc also plays a major role in many
metabolic activities in the body. Folic acid helps to prevent first occurrence
of spina bifida and other neural tube defects in the newborn.
PHARMACOLOGY:
PHARMACOKINETICS:
Folic acid is absorbed mainly
from the proximal part of the small intestine. Folate polyglutamates are
considered to be de – conjugated to monoglutamates during absorption. Folic
acid rapidly appears in the blood, where it is extensively bound to plasma
proteins. The amounts of Folic acid absorbed from normal diets are rapidly
distributed in body tissues and about 4 to 5 micrograms is excreted in the
urine daily. When larger amounts are absorbed, a high proportion is metabolised
in the liver to other active forms of folate and a proportion is stored as reduced
and methylated folate. Larger amounts of folate are rapidly excreted in the
urine. Zinc and its salts are poorly absorbed from GIT (in duodenum and ileum) and only small
portion of dietary Zinc is absorbed and is widely distributed throughout the
body and excreted mainly in the feces and only traces are found in the urine
since kidney has little role in regulating body Zinc content. Endogenous Zinc
be reabsorbed in ileum and colon creating enterohepatic circulation of Zinc.
After absorption Zinc is bound in the intestines to protein metallo thionein.
Zinc is primarily stored in RBCs, WBCs, muscle, bone, Skin, Kidneys, Liver,
pancreas, retina, prostate etc, The
extent of binding is 0% to plasma
albumin, 30-40% to alpha 2
macroglobulins or transferrin and 1% to amino acids like histidine and
cysteinc. Peak peas ma concentration occurs in approximately 2 hours and
elimination is primarily fecal constituting 90%
and small amounts in urine and sweat.
PHARMACODYNAMICS:
The daily folate requirement rises steeply
during the final trimester of pregnancy, and evidence of maternal depletion may
be found. To ensure normal tissue folate levels in the mother after delivery a
daily supplement of about 300 micrograms is required during the second and
third trimester of pregnancy. This does not obscure the blood picture of
addisonian pernicious anaemia.
Zinc is an essential element of
nutrition and traces are present is wide range of foods.
Zinc is an essential element of
nutrition and traces are present is wide range of foods Zinc salts (usually
Zinc sulfate) are used as supplements to correct Zinc deticiency and have been
used to treat large number of conditions because of an associated reduction in
the concentration of Zinc in the body
INDICATIONS:
folinz is recommended as a Vitamin & Zinc supplement and are in
especially beneficial in following condition:
For the prophylaxis and
treatment of nutritional megaloblastic anaemias associated with folic acid
deficiency, as in the anaemias of pregnancy, pellagra, sprue and that following
gastrectomy and in pernicious anaemia.
Vital role in various intercellular reactions likely conversion of
Serine, glycine, Synthesis of Purines,
DNA and RNA.
Coenzyme
for metabolic processes.
Used in the treatment of
folate deficiency.
Boosting up Immunities.
Proper growth of foetus.
For the periconceptual supplementation of Folic Acid to help prevent
first occurrence of spina bifida and other neural tube defects in the new born.
Prevent foetus malformations
due to Zinc deficiency in pregnancy.
CONTRAINDICATIONS:
folinz in contraindicated in patients
with known hypersensitivity to any of the ingedients in the formulation. It should never be used
in the therapy of patients with vitamin B12 deficiency of any cause unless here
is associated folate deficiency. Proper haematological diagnosis is essential.
WARNING:
Concurrent administration of Zinc
might diminish the effect of penicillamine. Folic should never be given alone
in the treatment of Addison’ s pernicous anaemia and other vitamin B 12
deficiency states because it may precipitate the onset of subacute combined
degeneration of the spinal cord.
SIDE EFFECTS:
folinz is generally well tolerated in recommended doses. Rare side
effects may include gastro – intestinal disturbances, nausea, vomiting and
diarrhoea. Accumulation of Zinc may occur in cases of renal failure.
PREGNANCY AND LACTATION:
there is published evidence that folic acid is
beneficial in the prevention of neural tube defects.
INTERACTIONS:
folic acid occasionally reduces
plasma levels of anticonvulsants. Particularly
phenytoin.
DOSAGE:
As directed by the Physician.
OVERDOSAGE:
No cases of acute overdosage of
Folic acid appear to have been reported, but even extremely hihg doses are
unlikely to cause harm to patients.
PRESENTATION:
Folinz tablets are available in blister strip of 30 tablets in an
attractive carton.
STORAGE:
Store below 25 C in a dry a place. Protect
from light Keep out of reach of children.
