Filtration
Filtration is the process of separating liquids from solids with the view of obtaining the liquids in a transparent condition.
The intervention of a porous substance, called the filter, is necessary in performing the process of filtration. The filter may be made of paper, paper pulp, sand, ground glass, charcoal, porous stone, etc.
The liquid, which has passed through the filter is called the filtrate and it should be perfectly clear.
Paper filters are the most useful of all filters for the pharmacist, and they are employed in all the finer operations requiring filtration, She solid particles are much more completely separated by filtration through good paper filters than through strainers, owing to the pores of the paper being smaller and more numerous. The paper used for this purpose is specially prepared and is called filter paper.
The filter in the runnel should, be moistened with the liquid to be filtered or with a liquid corresponding to the solvent employed. This promotes rapid, filtration, and washes the filter besides. If the liquid to be filtered contains free acid or alkali, or a very fine precipitate, or is very dense or hot, a double filter should be used.
One of the most important uses of precipitation is in testing as it affords the most ready means of identifying chemical substances or of ascertaining their purity. A great many pharmacopoeia! tests are based upon this process. The colour, quantity and character of the precipitate are all taken into account. The terms curdy, granular, flocculent, gelatinous, crystalline, bulky and others, which are sufficiently distinctive, are used to define the particular form which the precipitate assumes.

Methazid
White crystalline powder of bitter taste. Melting point is 175-180. Soluble in mineral and organic acids, insoluble in water and the usual organic solvents.
In its antitubercular potency methazid is close to phthivazid. It is considerably less toxic than tubazid and is readily absorbed from the gastrointestinal tract, penetrating into the spinal fluid.
Indications for use are the same as for phthivazid. Methazid is used in all forms of pulmonary tuberculosis in children and adults, both in fresh cases of the disease and during exacerbations of a chronic process and the presence of symptoms of intoxication. It is likewise indicated in tuberculosis of the larynx and oral cavity, tuberculosis of the serous membranes, tuberculosis of the peripheral lymph nodes, bones and joints, skin. In miliary tuberculosis and tubercular meningitis, methazid is used in conjunction with streptomycin.

Methazid is prescribed orally, before meals. During the first few days adults are given 0.2 gm twice a day, if the drug is tolerated well, the dose is increased to 0.3-0.5 gm 3 times daily. Children are given methazid in a daily dose of 0.02 gm per kg body weight, this being prescribed in 2-3 divided doses. The duration of treatment is the same as for phthivazid.
Methazid can be used in hospitals and sanatorium conditions, and also in outpatient conditions. The duration of treatment depends on the peculiarities of the disease in each case, the effectiveness of treatment, and so on. She course of treatment may last from 2 or 3 months to a year or more.
There is usually good tolerance to the drug. During lengthy use the same complications may set in as during the reception of other derivatives of isonicotinic acid. Hydrazide: vertigo, headache, pain in the region of the heart, dermatitism paresthesia, dysuric symptoms, nausea, vomiting, and anorexia. In such cases the dose must be reduced or the drag temporarily withdrawn.
