Tablet and spray formulations are referred to as short-acting preparations. Disadvantages of semi-solid dosage forms: The major disadvantage of the semi-solid dosage form is that it has no dose accuracy and it needs to be applied directly. Importantly, if the API falls into DCS IIb as it is highly insoluble, the development savings can be substantial if bioavailability challenges are addressed ahead of first-in-human studies, as this will minimise the chances that a reformulation will be necessary after trials have started. Suitable for substances having bitter taste and unpleasant odor. A majority of people suffer from severe migraine headaches due to several reasons with most being sensitive to intense light or sound. Like drip irrigation, micro-spray is considered a type of low-pressure irrigation typically operating with pressures between 15 and 30 psi. Chronic obstructive pulmonary diseases (including bronchitis and emphysema) Bronchiectasis. Nozzles are prone to becoming clogged, and rotary disk atomizers can become corroded over time. Besides using a nasal spray to stop runny nose, you can also cure chronic sinusitis to get better results. There are several reasons for this, but particularly notable is the fact that disintegration, flow and density challenges are amplified when developing a spray dried amorphous product, which may extend timelines and introduce complexities that are not commonly seen with more traditional tablets and powder-filled capsules. It is also important to consider moisture protection as amorphous APIs tend to be more hygroscopic than crystalline forms. Spray drying offers a gentle method of drying by exposing substances to only a short burst of extreme temperature, then providing a cooling effect via the evaporation process, which protects spray dried pharmaceuticals from higher bulk temperatures. An atomized feed generates a vast array of droplets from a liquid stream, creating a sizable surface area. (b) Irritation of mucosal surfaces can occur. Terminology: Decongestant Nasal Spray (DNS), Nose/Nasal Spray, Inhalation Spray, Oxymetazoline Hydrochloride(Afrin), or Nasal Oxymetazoline. Easy to use without any mixing of external components. This part becomes more sensitive and dry during summer disturbing which can lead to nose bleeding. (G) Zinc gluconate lozenges and zinc acetate lozenges: As it is known, zinc is an essential mineral and antioxidant found in every body cell.
