Merivit Plus Uses, Dosage, Side Effects, Food Interaction and all others data.

Pepsin is a potent enzyme in gastric juice that digests proteins such as those in meat, eggs, seeds, and dairy products .

Studies on gastric digestion from 1820-1840 led to the discovery of pepsin as the substance which, in the presence of stomach acid, causes nutrients including meat or coagulated egg whites to dissolve. Soon afterward, it was shown that these protein nutrients were cleaved by pepsin to products called peptones .

Pepsin is often used as a replacement enzyme for those with pancreatic insufficiency . Stimulation of the pancreas and therefore enzymatic digestion of food is a tightly controlled and is a hormonally mediated process. Any changes or conditions affecting metabolic steps for successful digestion and absorption negatively affect pancreatic enzymatic secretion, entry into the intestine, functionality once inside the intestine, and appropriate mixing with foods/nutrients. Many causes of pancreatic insufficiency require that enzyme replacement therapy is started, including cystic fibrosis, pancreatic cancer, acute and chronic pancreatitis, as well as pancreatic surgery .

Vitamin-B complex contains the most important members of the vitamin B group in pure form and in therapeutically balanced proportions. The members of the vitamin B group contained in Vitamin-B complex are components of enzyme systems that regulate various stages of carbohydrate, fat and protein metabolism, each of the components playing a specific biological role. Deficiency of B vitamin causes glossitis, stomatitis, cheilosis, polyneuritis, beriberi, pellagra and vascularisation of cornea.

Uses

Pepsin is a protease indicated in the treatment of digestive disorders.

Used as a pancreatic enzyme replacement in pancreatic insufficiency . It is intended to mimic naturally produced human pepsin .

Pepsin powder is prepared from the gastric mucosa of pigs, cattle or sheep . In the laboratory, it is primarily used for the unspecific hydrolysis of proteins and peptides in acidic media. In addition, it provides limited hydrolysis of native immunoglobulins, yielding biologically active fragments .

In certain supplements, pepsin may be combined with betaine and HCl (hydrochloric acid) to aid in digestion in various gastrointestinal conditions , .

Each Tablet/ Capsule contains:

Thiamine Hydrochloride 5 mg
Riboflavin 2 mg
Pyridoxine hydrochloride 2 mg
Nicotinamide 20 mg

Each 5 ml Syrup contains:

Thiamine Hydrochloride 5 mg
Riboflavin 2 mg
Pyridoxine hydrochloride 2 mg
Nicotinamide 20 mg

Each 2 ml Injection contains:

Thiamine Hydrochloride 50 mg
Riboflavin 4 mg
Pyridoxine hydrochloride 10 mg
Nicotinamide 100 mg
D-Panthenol 5 mg

Vitamin-B complex is used for prophylactic or therapeutic nutritional supplementation in physiologically stressful conditions. These include: Conditions causing depletion, or reduced absorption or bioavailability of essential B-vitamins manifested by glossitis, stomatitis, cheilosis, beriberi Vitamin-B complex is used for prophylactic or therapeutic nutritional supplementation in physiologically stressful conditions. These include: Conditions causing depletion, or reduced absorption or bioavailability of essential B-vitamins manifested by glossitis, stomatitis, cheilosis, beriberi

Merivit Plus is also used to associated treatment for these conditions: Diarrhoea, Gastritis Chronic, Hypochlorhydria, Postoperative digestive insufficiency

How Merivit Plus works

Glands present in the mucous membrane lining of the stomach produce and store an inactive protein named pepsinogen. Impulses from the vagus nerve and the hormonal secretions of the hormones gastrin and secretin promote the release of pepsinogen into the stomach, where it is mixed with hydrochloric acid and quickly converted to the active enzyme pepsin. The digestive potency of pepsin is highest at the acidic pH of normal gastric juice. In the intestine, the gastric acids are then neutralized, and pepsin is no longer effective .

Pepsin, the proteolytic enzyme of the stomach is normally responsible for less than 20% of the protein digestion occuring the gastrointestinal tract. It is an endopeptidase enzyme that metabolizes proteins to peptides. It preferentially hydrolyzes peptide linkages where one of the amino acids is aromatic. Pepsin, like other protease enzymes, is produced from an inactive precursor, pepsinogen, which is stored in granule form in the chief cells of the stomach and are released by a process called exocytosis .

In the digestive tract, pepsin activity only contributes to the partial breakdown of proteins into smaller units called peptides, which then either are absorbed from the intestine into the bloodstream or are broken down further by pancreatic enzymes .

Dosage

Merivit Plus dosage

Tablet/ capsule:usual recommended dose is 1-2 tablet/capsule 3 times daily or as directed by the physician.

Syrup:2-3 teaspoonful daily or as directed by the physician.

Injection:It is for intramuscular and intravenous administration. Usual recommended dose is 2 ml daily or as directed by the physician. In addition withThiamine, Riboflavin, Nicotinamide, Pyridoxine; injectable dosage from containsD-Panthenol 5 mg.

Side Effects

Adverse reactions have been reported with specific vitamins and minerals, but generally at levels substantially higher than those in Vitamin-B complex. However, allergic and idiosyncratic reactions are possible at lower levels. Iron, even at the usual recommended level has been associated with gastrointestinal intolerance in some patients.

Toxicity

Oral LD50 Rat 90000 mg/kg

Chronic backflow of pepsin, acid, and other substances from the stomach into the esophagus, is the basis of reflux conditions, particularly gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux. In the latter, pepsin and acid travel all the way up to the larynx, where they can lead to damage of the laryngeal mucosa and lead to symptoms ranging from hoarseness of the voice and chronic cough to laryngospasm (involuntary contraction of the vocal cords) as well as laryngeal cancer .

Though limited data is available on the toxicity of exogenous pepsin (not naturally produced in one's gastrointestinal tract), it can be extrapolated from the above-mentioned information that pepsin overdose may lead to mucosal tissue damage of the gastrointestinal tract.

Interaction

As little as 5 mg pyridoxine daily can decrease the efficacy of levodopa in the treatment of parkinsonism. Therefore, Vitamin-B complex is not recommended for patients undergoing such therapy
