INPROCESS QUALITY CONTROL


This Program ensures finished dosage forms have uniform quality and purity within a batch and between batches.

This program is accomplished by identifying critical steps in the manufacturing process and controlling them within defined limits.

SUPER INFECTION

Super infection, according to Dorland’s illustrated is a condition produced by sudden growth of a type of bacteria, different from the original offenders in a wound or lesion under treatment.
In virology, super infection is the process by which a cell that has previously been infected by one virus gets confected with another virus at a later point in time. In medicine, super infection is an infection, especially

DRUG RESISTANCE


Drug resistance is the reduction in effective of a drug in curing a disease or improving a patient’s symptoms when the drug is not intended to kill or inhibit a pathogen then the term is equivalent to dosage failure or drug tolerance. More commonly the term is used in the context of diseases caused by pathogens.
Pathogens are said to be drug resistant when drug meant to neutralize then have reduced effect.

CHEMOTHERAPEUTIC INDEX

Chemotherapeutic agents need to act at a concentration that can be tolerated by the tissues of the host and therefore they must have a selective toxicity for micro organism compared with the host.
This selective toxicity expressed in terms of the “Chemotherapeutic Index” that compress the maximum dose that can be tolerated by the host without causing death (The maximum tolerated dose) with the minimum

NON PHARMACOLOGICAL THERAPY OF HYPERTENSION


Weight reduction and regular aerobic exercise (E.g: Jogging) are recommended as the first step in treating mild to moderate hypertension.
Regular mild exercise improves blood flow and helps to reduce resting heart rate and blood pressure.
These steps are highly effective in reducing B.P.

EYE DROPS


Definition: Aqueous or oily solutions or suspensions for instilling into the conjuctival sac.
Eye drops are used as
ü  Anaesthetics,
ü  Anti-inflammatory agents

EXHIBIT BATCH VS PILOT BATCH

Exhibit batch is one which can be manufactured in production plant or even in pilot plant which have similar equipments such as in production facility. An exhibit batch is also called LATE PILOT BATCH which is used to provide the major stability data as per ICH guidelines to submit for an ANDA application.

PREVENTION OF CROSS-CONTAMINATION DURING PROCESSING

       Line clearance should be performed as per SOP & check list and recorded.
·         Check for absence of any starting materials, products, product residues, documents of previous product.
·         Wherever possible adopt “Closed system” while handling materials.
·         Processing of only one material at a time in same cubicle.

SOP FOR BURSTING STRENGTH TESTER

Objective
To provide a procedure for the operation of bursting strength tester.
Scope
Applicable to the bursting strength tester in quality control department.

PRINCIPLE AND CALIBRATION OF ULTRAVIOLET AND VISIBLE ABSORPTION SPECTROPHOTOMETRY

Ultraviolet and visible absorption spectrophotometry is the measurement of the absorption of monochromatic radiation by solution of chemical substances, in the range of 185 nm to 380 nm, and 380 nm to 780 nm of the spectrum, respectively.
The magnitude of the absorption of a solution is expressed in terms of the absorbance, A, defined as the

CALIBRATION OF UV/ VISIBLE SPECTROPHOTMETER

ATOMIC EMISSION SPECTROMETRY

The technique is used to determine the concentration of certain metallic ions by measuring the intensity of emission of light at a particular wavelength by the vapour of the element generated from the substance. The measurement of the intensity of one of the emission lines of the atomic vapour of the element generated from a solution of that element is the basis of atomic emission spectrometry. The determination is carried out at the

ATOMIC ABSORPTION SPECTROMETRY

This technique is based on the fact that when atoms, ions or ion complexes of an element in the ground state are atomized in a flame, they absorb light at the characteristic wavelength of that element. If the absorption process takes place in the flame under reproducible conditions, the absorption is proportional to the number of absorbing atoms.
