Sildenafil does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).
7. Conclusions
Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily. If you are taking sildenafil to treat erectile dysfunction, you should know that it does not cure erectile dysfunction or increase sexual desire. Sildenafil comes as a tablet and suspension (liquid) to take by mouth.

Pharmacopeial Convention, Inc; January 2018.2. Extemporaneous sildenafil citrate oral suspensions for the treatment of pulmonary hypertension in children. Design and physicochemical stability studies of paediatric oral formulations of sildenafil. Extended stability of morphine and sildenafil for oral use in infants and young children. Allen LV Jr. The best time to take sildenafil is about 1 hour before sexual activity, but you can take the medication any time from 4 hours to 30 minutes before sexual activity. Sildenafil usually should not be taken more than once every 24 hours. If you have certain health conditions or are taking certain medications, your doctor may tell you to take sildenafil less often. You can take sildenafil with or without food. However, if you take sildenafil with a high-fat meal, it will take longer for the medication to start to work.

Standard operating procedure for performing physical quality assessment of oral and topical liquids. Bethesda, MD: American Society of Health-System Pharmacists; 2016:1918-1932.7. To comment on this article, contact rdavidson@uspharmacist.com. Sildenafil (Viagra) is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Sildenafil (Liqrev, Revatio) is used to improve the ability to exercise in adults (Liqrev, Revatio) and children 1 year of age and older (Revatio) with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). If you are taking sildenafil to treat PAH, you will probably take sildenafil three times a day with or without food.

How to Become a Distributor:
Stability: A beyond-use date of up to 91 days may be used for this preparation.1-4 Quality Control: Quality-control assessment can include weight/volume, pH, specific gravity, active drug assay, color, rheologic properties/pourability, physical observation, and physical stability (discoloration, foreign materials, gas formation, mold growth).5 Discussion: A number of stability studies have been conducted on oral liquid formulations of sildenafil for pediatric use. From these, it appears that sildenafil is relatively stable in vehicles, with an acidic pH around 4 to 5. Sildenafil for oral suspension at 10 mg/mL (Revatio) is commercially available with a beyond-use date of 60 days after reconstitution. One study involved compounded sildenafil citrate in a citrate-buffered solution (0.1 M, pH 4) and either a syrup excipient (resulting in a suspension) or a sugar-free syrup excipient (resulting in a solution); both had pH values of approximately 4.2. Both the suspension and the solution were slightly pink and fruit-flavored.
Warnings for other groups
The suspension demonstrated stability for 91 days at both 4°C and 25°C; however, the solution was stable only for 30 days, possibly related to a nonredispersible sediment at the bottom of the container.3 A study by Nahata and colleagues that involved sildenafil citrate tablets (Revatio 20 mg) with a mixture of 1:1 Ora-Sweet and Ora-Plus at 2.5 mg/mL and pH 4.5-4.7 demonstrated stability of 91 days at both 4°C and 25°C. Also studied was a mixture of 1:7 (1% methyl cellulose:simple syrup) at pH 5.1 to 4.9 that also demonstrated stability of 91 days at both 4°C and 25°C.4 Sildenafil citrate (C22H30N6O4S.C6H8O7, MW 666.70) occurs as a white to off-white, crystalline powder that is soluble 3.5 mg/mL in water. It is formulated as tablets equivalent to 25 mg, 50 mg, and 100 mg of sildenafil for oral administration. The tablets also contain microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, hydroxypropyl methylcellulose, titanium dioxide, lactose, triacetin, and FD&C Blue #2 Aluminum Lake.6,7 Ora-Plus is an oral suspending vehicle that accepts dilution of up to 50% or more with water, flavoring agents, or syrups while still retaining its suspending properties. It has a pH of approximately 4.2 and an sildenafil citrate 120 mg osmolality of about 230 mOsm/kg.
