innovator product with which extensive clinical trials have been conducted to establish as therapeutic efficacy and safety profile by the innovator company. For most molecules the pharmacodynamics are closely linked to the pharmacokinetic profile (PK PD correlation) thus if the pharmacokinetic profile is matched with that of the innovator product‚ It is expected to have the same efficacy and safety profile. This gives the generic manufacturers a huge saving in the costs which goes into developing new drug

other AEDs tested revealed any binding to SV2A. The severe seizures observed in mice lacking SV2A support the interpretation that this protein influences mechanisms of seizure generation or propagation. Pharmacokinetics Levetiracetam comes especially close to fulfilling the desirable pharmacokinetic characteristics for an AED: (1) it has a high oral bioavailability; (2) it is not significantly bound to plasma proteins; (3) it is eliminated partly in unchanged form by the kidneys and partly by hydrolysis

modification to the pharmacokinetics of the drugs in older people. Absorption changes result from Morphological changes to the gastrointestinal mucosa. GI function changes have an effect on enzymatic breakdown‚ dissolution‚ and drug ionization which then leads to alterations in oral drug absorption. Intestinal absorption of some drugs is delayed due to reduction rate in gastric emptying. Another example is Elimination changes‚ which are caused by altered pharmacokinetics in renal function.

The high cost of mAbs also prevents it from being a more common therapeutic method for treating maladies. These costs can be attributed to the multiple large doses that must be administered intravenously at regular intervals in order to maintain systemic volumes of distribution. Therefore‚ it is beneficial to explore an alternative method of delivery that can sustain delivery of mAbs in its therapeutic window for long periods of time. Oral antibody dosing shows almost zero bioavailability. Intravenous

[2] The amount of administered dose of unchanged drug that reaches the systematic circulation is known as bioavailability. Bioavailability is important in pharmacokinetics‚ as it must be considered when calculating dosage for non-intravenous routes of administration. Bioavailability is affected by first pass metabolism‚ solubility and stability of the drug. Due to the low

Research Paper Critique Overcoming Biological Barriers 2013-2014 Abstract Is the abstract a concise summary? Does it focus on results and conclusions? The abstract of this paper is concise. The aim of this study was made clear. It was clear from the abstract that the aim of this paper was to develop chitosan microspheres of verapamil to administer it intranasally in order to enhance its low bioavailability. It was an interesting fact that the abstract

Pharmacokinetics and Pharmacodynamics Scenario Once a patient is admitted to the hospital‚ one key element is asked before a medication can be prescribe. That is the patient allergy. As mention in the media presentation‚ “no one drug works for every patient and you can never say a patient will not have a bad reaction to a drug” (Laureate Education‚ 2012) I can recalled a particular situation a few years ago with the administration of Narcan (naloxone). One morning during rounds‚ I received EB with
