What is purified water and injection IP?

Is purified water the same as water for injection?

Water for injection has the highest purity possible and it is sterile. … The main difference between a PW and a WFI loop is that the purified water is held at room temperature while the WFI is kept at 80-90oC.

What is purified water IP?

Purified water is used in many pharmaceutical products as an ingreadient as well as it is used for washing of manufacturing equipment. …

Can I use purified water for injection?

Purified water.

Purified water is most commonly used as a diluent in the production of non-sterile products for injection, infusion or implantation, cleaning equipment, and cleaning non-sterile product-contact components.

What is water for injection IP?

Sterile Water for Injection, IP is a sterile, nonpyrogenic preparation of water for injection which contains no bacteriostat, antimicrobial agent or added buffer and is supplied only in single-dose containers to dilute or dissolve drugs for injection.

How do you make a purified water IP?

Distillation. Distilled water is produced by a process of distillation. Distillation involves boiling the water and then condensing the vapor into a clean container, leaving solid contaminants behind. Distillation produces very pure water.

What is the pH for sterile water for injection IP?

Sterile Water for Injection, USP, is sterile, nonpyrogenic, distilled water in a single dose container for intravenous administration after addition of a suitable solute. It may also be used as a dispensing container for diluent use. No antimicrobial or other substance has been added. The pH is 5.5 (5.0 to 7.0).

Can you drink purified water?

While most sources of public drinking water are closely regulated and safe to drink, many prefer to drink purified water. Purified water is relatively safe and may reduce exposure to certain contaminants that can be found in tap water. Remember that water quality can vary depending on where you live.

Is purified or distilled water better?

Purified water is usually a good option since the purification process removes chemicals and impurities from the water. You should not drink distilled water since it lacks naturally-occurring minerals, including calcium and magnesium, that are beneficial for health.

How do you prepare water for injection IP?

Water For Injection System (WFI) can be created through distillation and through further purification by Reversed Osmosis. The more common method is through distillation, which is an intrinsically safe method. If a distiller would fail or produce insufficient heat, there is no evaporation and no WFI generation.

What is purified water in pharmacy?

Purified water is intended for use in formulation of medicines that are not intended to be sterile and apyrogenic. It is also the feed water for the production of water for injection (WFI) and for pharmaceutical grade clean steam. …

What is the difference between purified water and potable water?

Nowadays water is frequently purified by processes like capacitive deionization, carbon filtering, reverse osmosis, micro-filtration, ultra-filtration, ultraviolet oxidation etc. Potable water is water which is fit for consumption by human beings and other animals. … One of the easiest way to treat water is boiling.

What are the different types of water for injection?


  • Non-potable.
  • Potable (drinkable) water.
  • USP purified water.
  • USP water for injection (WFI)
  • USP sterile water for injection.
  • LUSP sterile water for inhalation.
  • USP bacteriostatic water for injection.
  • USP sterile water for irrigation.

Why water for injection should be stored at 2 C or 80 C?

According to the USP, a temperature of 80 °C during sanitisation serves to achieve the necessary germicidal temperature even at colder points in the (ring pipe) system. … A suitable reduction of the sanitising temperature can therefore reduce operating costs, decrease rouging and extend the longevity of plant components.

What happens if you inject sterile water?

Sterile water for injection is 0 mOsm/L, which can be fatal. It should never be given intravenously to patients. PA-PSRS and other medication error reporting pro- grams have received reports of events involving the IV administration of sterile water to patients.

When should I use water injection?

Water for injections is used to dissolve or dilute substances or preparations for parenteral administration. Water for injections may also be used as an irrigating solution for small wounds or during minor surgical procedures.
