It is an antimicrobial (triple, quadruple drugs) drug .

Antimicrobial that are used clinically against H.pylori are:- Amoxicillin, Clarithromycin, tetracycline and metronidazole/ Tinidazole. Any single antibiotic is ineffective.

H.pylori is agents used in treatment of Helicobacter Pylori are medicines used for stomach acid inhibition, combined with antibacterial agents. Treatment is for one week with a proton pump inhibitor or an antacid (or antisecretory agents), and two appropriate antibacterial agents. This one week triple therapy does give a good eradication rate.

PHARMACOLOGY & MECHANISM OF ACTION:-

H.pylori is a gram negative bacillus uniquely adapted to survival in the hostile environment of stomach. It attached to the surface epithelium beneath the mucus, has High urease activity produced ammonia which maintains a neutral microenvironment around the bacteria,and promotes back diffusion OF H+ ions. It has been found as a commensal in 20-70% normal individuals,and is now accepted as an important contributors to the causation of chronic gastritis, dyspepsia,peptic ulcer, gastric lymphoma and gastric carcinoma . H .pylori infection starts with a neutrophilic gastric lasting 7-10days which is usually asymptomatic. Once established,H.pylori generally persists of duodenal and gastric ulcer have tested positive for H. Pylori

Eradication of H . Pylori concurrently with H2 blocker / PPI therapy of peptic ulcer has been associated with faster ulcer healing and largely prevents ulcer relapse. All H.pylori positive ulcer patients should receive H.pylori eradication therapy. In the absence of H. Pylori testing,all cases with failed conventional ulcer therapy and relapse cases must be given the benefits of H.pylori eradication.

Antimicrobial that are used clinically against H.pylori are:- Amoxicillin, Clarithromycin, tetracycline and metronidazole/ Tinidazole. Any single antibiotic is ineffective. Resistance develops rapidly, especially to metronidazole/ tinidazole and Clarithromycin,but Amoxicillin resistance is infrequent. In tropical countries, metronidazole resistance is more common than Clarithromycin resistance. Since bismuth (CBS) is active against H. pylori and resistance does not develop to it , combination regimens including bismuth may be used in case of metronidazole and Clarithromycin double resistance. Routine use of CBS is precluded by poor patient acceptability. Acid supression by PPIs/H2 blockers enhances effectiveness of anti -H . Pylori anti biotics, and optimum benefits are obtained when gastric pH is kept > 5 for at least 16-18 hours per day . This is a higher degree of round - the - clock acid supression than is needed for duodenal ulcer healing or for reflux esophagitis. Only twice daily PPI dosing can achieve this degree of acid supression. The PPIs benefits by altering the acid environment for H. Pylori as well as by direct inhibitory effects. One of the PPIs is an integral component of all anti-H .pylori regimens along with 2 (triple) or 3 (quadruple) drugs antimicrobials.

USED:- in Helicobacter pylori infection ,lower ulcer disease prevalence and prevention of gastric carcinoma/Lymphoma etc.

DOSE:- 1 weeks - twice daily

2 weeks -Twice daily.

Mainly treatment course are 14 days

SIDE EFFECTS:-

Mainly diarrhoea & stomach cramps or other.

BENDROFLUMETHIAZIDE Uses, Side Effects, and More

BENDROFLUMETHIAZIDE Brand name:- Bendrofulazide, Aprinox. BENDROFLUMETHIAZIDE is a type of medicine called a diuretic. It's used to treat high blood pressure (hypertension) and the build-up of fluid in your body (oedema). Diuretics are sometimes called "water tablets" because they make you pee more. This helps get rid of extra fluid in your body. Bendroflumethiazide is only available on prescription. It usually comes as tablets. It can also come as a liquid you swallow, but this has to be specially ordered. PHARMACODYNAMIC:- Bendroflumethiazide, a thiazide diuretic, removes excess water from the body by increasing how often you urinate (pass water) and also widens the blood vessels which helps to reduce blood pressure. It inhibits Na+/Cl- reabsorption from the distal convoluted tubules in the kidneys. Thiazides also cause loss of potassium and an increase in serum uric acid. Thiazides are often used to treat hypertension, but their hypotensive effects are not necessari...

CLOMIPHENE CITRATE Uses, Side Effects, and More

CLOMIPHENE CITRATE BRAND NAME:- CLOMIPHENE, FERTOMED, CLOFERT, CLOME 25,50,100mg tab. Clomiphene is a selective estrogen receptor modulator (SERM) which treats female infertility. It works by promoting the release of reproductive hormones. This helps stimulate the release of eggs from the ovary (ovulation). PHARMACODYANIMCS:- Clomifene (previously clomiphene) is an orally administered, non steroidal, ovulatory stimulant that acts as a selective estrogen receptor modulator (SERM). Clomifene can lead to multiple ovulation, and hence increase the risk of conceiving twins. In comparison to purified FSH, the rate of ovarian hyperstimulation syndrome is low. There may be an increased risk of ovarian cancer and weight gain. Clomifene is capable of interacting with estrogen-receptor-containing tissues, including the hypothalamus, pituitary, ovary, endometrium, vagina, and cervix. It may compete with estrogen for estrogen-receptor-binding sites and may delay replenishment of intracel...

Carbidopa Uses, Side Effects, and More

Carbidopa Brand name:- lodosyn. Carbidopa is always given with levodopa. It works by preventing levodopa from being broken down before it reaches the brain. This allows for a lower dose of levodopa, which causes less nausea and vomiting. Pharmacodynamic:- When mixed with levodopa, carbidopa inhibits the peripheral conversion of levodopa to dopamine and the decarboxylation of oxitriptan to serotonin by aromatic L-amino acid decarboxylase. This results in an increased amount of levodopa and oxitriptan available for transport to the central nervous system. Carbidopa also inhibits the metabolism of levodopa in the GI tract, thus, increasing the bioavailability of levodopa. The presence of additional units of circulating levodopa can increase the effectiveness of the still functional dopaminergic neurons and it has been shown to alleviate symptoms for a time. The action of carbidopa is very important as levodopa is able to cross the blood-brain barrier while dopamine cannot...
