ANALYTICAL METHOD DEVELOPMENT AND VALIDATION FOR SIMULTANEOUS DETERMINATION OF ZALTOPROFEN AND PARACETAMOL IN THEIR COMBINED SOLID DOSAGE FORM BYRP-HPLC METHOD
A simple, sensitive, linear, precise and accurate RP-HPLC method for simultaneous estimation of Zaltoprofen and Paracetamol in bulk and tablet formulation was developed and validated. The proposed RP-HPLC method utilizes Phenomenex C18 column (150 ×4.6 mm i.d., 5 µm), optimum mobile phase consisted of isocratic run of Phosphate buffer (pH-4.2): acetonitrile (40:60V/V) with the effluent flow rate...
A REVIEW ON PHARMACEUTICAL PREFORMULATION STUDIES IN FORMULATION AND DEVELOPMENT OF NEW DRUG MOLECULES
Preformulation is a group of studies that focus on the physicochemical properties of a new drug candidate that could affect the drug performance and the development of a dosage form. This could provide important information for formulation design or support the need for molecular modification. Every drug has intrinsic chemical and physical properties which has been consider before development of p...
Evolution of an existing drug molecule from a conventional form to a novel delivery system can significantly improve its performance in terms of patient compliance, safety and efficacy. In the form of a Novel Drug Delivery System an existing drug molecule can get a new life. An appropriately designed Novel Drug Delivery System can be a major advance for solving the problems related towards the rel...
This article mainly focuses on the approval process of drug import and export from India. Now a day’s foreign pharmaceutical companies have a better legal foundation for releasing new drugs in India. The Indian medical regulatory system has become more complicated, and new drugs can take a year or more to be approved for marketing. Ever-changing laws and regulations are driving demand for regula...
Heterocyclic compounds are of very much interest in our daily life. Heterocyclic compounds have one or more hetero atoms in their structure. They may be cyclic or non cyclic in nature. Heterocyclic compunds have a wide range of application. They are predominantly used as pharmaceuticals, as agrochemicals and as veterinary products. They also find applications as sanitizers, developers, antioxida...
Aim: To evaluate safety and efficacy of diclofenac 75 mg/1ml (Dynapar AQ) administered as IV bolus versus diclofenac 75mg/3ml administered as IV infusion in patients with postoperative pain. Methods: 350 postoperative adult patientswere randomized to receive either treatment. Primary efficacy endpoints were time to onset of analgesia and postoperative pain intensity while secondary efficacy end...
In the present article attempt has been made to explain the basic ideas and the significance of Thin layer Chromatography (TLC) in different analytical methods. As TLC is less time consuming, low cost, and can be performed with less complicated technique it has a wide application in pharmaceutical analysis. If performed precisely 32 amino acids can be separated by TLC. Also it has a wide app...
A transdermal patch is a medicated adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin and into the bloodstream. Often, this promotes healing to an injured area of the body. An advantage of a transdermal drug delivery route over other types of medication delivery such as oral, topical, intravenous, intramuscular, etc. is that the patch provides a con...
RP-HPLC METHOD FOR SIMULTANEOUS ESTIMATION OF IMPURITIES FROM EMTRICITABINE AND TENOFOVIR DISOPROXIL FUMARATE TABLET
Stability indicating RP-HPLC gradient method developed for simultaneous determination of impurities and degradation products from Emtricitabine and Tenofovir Disoproxil Fumarate in pharmaceutical tablet dosage form. The chromatographic separation was achieved by using column ACE C18 (250 x 4.6, 5μ). The mobile phase-A consists of 0.01M potassium dihydrogen phosphate buffer with pH 4.0 adjusted us...
