Fumigation Method for Pest Control Used in Aseptic Area
Fumigation:
Fumigation is a method of pest
control that completely fills an area with gaseous pesticides or fumigants
to suffocate or poison the pests within. It is utilized for control of pests.
Process:
Fumigation usually involves the following phases: First the area to be
fumigated is cleaned and disinfected as per SOP Clean up of Aseptic
Area. Next the fumigant (40
% formaldehyde solution is widely used as fumigant) is released (create fume by heating the
solution with a heater) into the space to be fumigated. After completely
evaporation of formaldehyde
solution the space is held for a
set period (eg. 6 hours) while the fumigant gas percolates through the space
and acts on and kills any infestation in the product, next the space is
ventilated so that the poisonous gases are allowed to escape from the space,
and render it safe for humans to enter.
Preparation of Fumigation Solution:
Prescription: Use formaldehyde at the rate of 2.5-mg/ liter volume space. [1litre
ยบ 0.03531466 cft]
Take the required
quantity of 40 % formalin according to the prescription and add 25 %
distilled water to make the stock solution.
Calculation:
40 % commercial formalin i.e.,
100ml contains 40gm of formaldehyde.

Parameters and Specification of Dissolution & Disintegration of Tablets
Tablets (Disintegration & Dissolution)
Tablets
are solid preparations each containing a single dose of one or more
active substances. They are obtained
by compressing uniform volumes of particles or by another suitable manufacturing technique,
such as extrusion, moulding or freeze- drying (lyophilisation). Tablets are
intended for oral administration. Some are
swallowed whole, some after being chewed, some are dissolved or
dispersed in water before being
administered and some are retained in the mouth where the active substance is liberated.
The
particles consist of one or more active substances with or without
excipients such as diluents, binders,
disintegrating agents, glidants, lubricants, substances capable of modifying the behaviour of the
preparation in the digestive tract, colouring
matter authorised by the competent authority and flavouring
substances.
Several categories of
tablets for oral use may be distinguished:
·
uncoated tablets;
·
coated tablets;
·
effervescent
tablets;
·
soluble tablets;
·
dispersible tablets;
·
orodispersible tablets;
·
gastro-resistant tablets;
·
modified-release tablets;
·
tablets for use in the mouth;
·
oral lyophilisates.

Dissolution:
Four types of apparatuses
are now described in the British and European Pharmacopoeias; the basket, the paddle, the reciprocating
cylinder and the flow-through
cell. The descriptions are concordant with those published in the United
States Pharmacopeia (USP).
Of the
two established apparatuses (basket
and paddle) the paddle is now the apparatus of choice for many
preparations. However, where a published test uses the basket, work to
validate a change to the paddle method is not contemplated. The reciprocating
cylinder is useful for pH profiling studies while the flow-through cell may
be appropriate for preparations of poorly soluble active ingredients (see
Annex).
Test conditions The harmonised test conditions included in Appendix XII B1 will be applied to
all new monographs of the British Pharmacopoeia. It is not the intention of
the British Pharmacopoeia Commission to apply these criteria retrospectively
to existing monographs. Where an individual monograph prescribes the use of
the requirements stated under Monographs of the British Pharmacopoeia
in Appendix XII B1, the following conditions using the basket or paddle
apparatus are preferred.
ร
rotation speed:100 rpm (basket), 50 rpm (paddle)
ร
dissolution medium volume: 900 ml
ร
dissolution medium composition: aqueous, commonly
0.1M hydrochloric acid or phosphate buffers of pH 6.8 to 7.6
ร
number of units tested: 6 (plus 6, if a retest is required).
The
number of units tested is specified in Appendix XII B1; other conditions are
specified in the relevant individual monographs.
In
situations where it has been demonstrated that the harmonised criteria are
not applicable (e.g. low solubility preparations, 'coning' of material in the
vessel, low concentration of analyte), modifications may be made to the test
conditions, such as, adding a surfactant, increasing the paddle rotation
speed or using a modified vessel and reducing the volume of dissolution
medium used.
