Paracetamol:-

Paracetamol is a metabolite of phenacetin.It is also known as Acetaaminophen.It is potent antipyretic and is also effective as an analgesic in mild or moderate degrees of msculo-skeletal pain.But it possesses no anti-inflammatory effect.Paracetamol is well absorbed on oral administration.It is metabolized in liver and excreted in urine in a conjugated form.

Aceclofenac:-

Aceclofenac is a non steroidal anti inflammatory drug(NSAID).It is used for the pain and inflammation in rheumatoid arthritis,osteoarthritis and ankylosing spondylitis.Aceclofenac has higher anti-inflammatory action than conventional NSAIDs.It is a cytokine inhibitor.Aceclofenac works by blocking the action of a substance in the body called cyclo oxygenase.Cyclo oxygenase involvde in the production of prostaglandins(chemical in the body) which causes the pain,swelling and inflammation.aceclofenac is a glycolic ester of diclofenac.

Cefixime:-

Cefixime is oral third generation cephalosporin antibiotic.cefixime is a cephalosporin antibiotic used to treat infections caused by bacteria.These include infections of the ear(otitis media caused by haemophilus influenzae,moraxella catarrhalis and S.pyogenes)Nose,sinuses(sinusitis),Throat(tonsillitis,pharyngitis caused by S.pyrogenes),chest and lungs(bronchitis,pneumonia caused by streptococcus pneumoniae and Haemophilus influenzae) and urinary system and uncomplicated gonorrhea caused by Neisseria gonorrhoeae.The bactericidal action of cephalosporin due to the inhibition of cell wall synthesis.

Pantoprazole:-

Pantoprazole is a proton pump inhibitor drug that inhibit the gastric acid secretion.pantoprazole is metabolized in the liver by the cytochrome P450 system.Metabolism mainly consists of demethylation by CYP2C19 followed by sulfation.Other metabolic pathway is oxidation by CYP3A4.Pantoprazole metabolites are not thought to have any pharmacological significance.Pantoprazole is rarely free of drug interaction.Generally inactive at acidic PH of stomach,thus it is usually given with a pro kinetic drug.Pantoprazole binds irreversibly to proton pumps and suppress the secretion of acid.Pantoprazole is used to short term treatment of erosion and ulceration of the esophagus caused by gastroesophageal reflux disease.

Domperidone:-

Domperidone is an antidopaminergi drug,used orally,rectally or intravenously,generally to suppress the nausea and vomiting,as prokinetic agent and for promoting lactation.Domperidone blocks the action of dopamine.It has strong affinities for the D2D3 dopamine receptors,which are found in the Chemoreceptor trigger zone(CTZ),located just outside the blood brain barrier,which among others, regulates nausea and vomiting(area postrema on the floor of the fourth ventricle and rhomboid fossa).Domperidone has anti emetic activity.Domperidone is used together with metolopramide,cyclizine and 5HT3 receptor antagonists(such as granisetron) in the treatment of nausea and vomiting.Domperidone is a first choice antiemetic in some countries.Domperidone is sometimes purchased from pharmacies in other countries for this purpose.It can be used in the patient with Parkinson disease unlike metoclopramide, domperidone does not cross the blood-brain barrier.Domperidone is also found effective in the treatment of gastroparesis,a stomach motility condition and for paediatric gastroesophageal reflux(infant vomiting).

Ceftriaxone:-

Ceftriaxone is a third generation cephalosporin antibiotic like other third generation cephalosporins, it has broad spectrum activity against gram-positive and Gram-negative bacteria.in most cases it is considered to be equivalent to cefotaxime in terms of safety and efficacy.ceftriaxone is often used(in combination,but not direct,with macrolide and/or aminoglycoside antibiotics)for the treatment of community acquired or mild to moderate healthcare associated pneumonia.It is also a choice drug for the treatment of bacterial meningitis.In pediatrics,it is commonly used in febrile infants between 4 and 8 weeks of age who are admitted to the hospital to exclude sepsis.It haso been used in the Lyme disease,Typhoid fever and Gonorrhea.Ceftriaxone 98% bound to plasma proteins.Ceftriaxone cross the blood brain barrier.

Sulbactam:-

Sulbactam is a molecule which is given in combination with beta-lactam antibiotics to inhibit beta lactamase,an enzyme produced by bacteria that destroys the antibiotics.sulbactam is a irreversible inhibitor of beta-lactamase,it binds the enzyme and does not allow it to interact with the antibiotic.Sulbactam is able to inhibit the most ommon forms of beta lactamase.sulbactam is a penicillinate sulfone.Being a beta lactamase inhibitor,it is synergistic with many beta lactamase labile drugs penicillins and cephalosporins.The combination of sulbactam and ceftriaxone is active against all the organisms sensitive to ceftriaxone.In addition,it demonstrates synergistic activity(reduction in MICs for the combination versus those of each component) in avariety of organism.Sulbactam is metabolized to a single metabolite that lacks pharmacological and antibacterial activities.sulbactam is eliminated via kidney by glomerular filteration and tubular secretion.sulbactam is also secreted in to the bile.sulbactam is approximately 30% bound to plasma proteins.

Vitamins:-

Vitamins are essential microconstituent of diet,which do not give energy but are necessary for the normal metabolism of the body.although some of the vitamins like vitamin k,pantothenic aid,folic acid,cyanocobolamin,vitamin D are synthesized in the body but their rate of production is not sufficient for maintenance of health.The importance of vitamins as drug is primarily in the prevention and treatment of deficiency diseases.The deficiency states can develop due to inadequate diet,impaired absorption,in efficient utilization,increased requirement or increased rate of excretion.Although rare,toxic effects of vitamin A,D and B6 are well known.
Vitamins are broadly classified in to two groups.
1)Water soluble vitamins:-B complex,C.These are meagerly stored in the body and the excess is excreted with little chance of toxicity.
2)Fat soluble vitamins:-A,D,E,K.These are stored in the body for prolonged periods and liable to cause cumulative toxicity after regular ingestion of large amount.
