Sildenafil oral suspension formulation for erectile dysfunction: is it love at first sight?. Efficacy of topical sildenafil formulations in enhancing wound healing outcomes: a narrative review Archives of Dermatological Research (2025) REVATIO- sildenafil citrate tablet, film coated REVATIO- sildenafil citrate injection, solution REVATIO- sildenafil citrate powder, for suspension Pfizer Laboratories Div Pfizer Inc REVATIO is indicated for the treatment of pulmonary arterial hypertension (WHO Group I) in adults to improve exercise ability and delay clinical worsening. The delay in clinical worsening was demonstrated when REVATIO was added to background epoprostenol therapy [see Clinical Studies (14)]. Studies establishing effectiveness were short-term (12 to 16 weeks), and included predominately patients with New York Heart Association (NYHA) Functional Class II–III symptoms and idiopathic etiology (71%) or associated with connective tissue disease (CTD) (25%). Limitation of Use: Adding sildenafil to bosentan therapy does not result in any beneficial effect on exercise capacity [see Clinical Studies (14)].
- Sildenafil oral solution is a liquid form of erectile dysfunction medication.
- It allows for easier swallowing compared to pills.
- Typically, it's used when oral tablets are unsuitable.
The recommended dose of REVATIO is 5 mg or 20 mg three times a day. Administer REVATIO doses 4–6 hours apart. In the clinical trial no greater efficacy was achieved with the use of higher doses.

Treatment with doses higher than 20 mg three times a day is not recommended. REVATIO injection is for the continued treatment of patients with PAH who are currently prescribed oral REVATIO and who are temporarily unable to take oral medication. The recommended dose is 2.5 mg or 10 mg administered as an intravenous bolus injection three times a day. The dose of REVATIO injection does not need to be adjusted for body weight. A 10 mg dose of REVATIO injection is predicted to provide pharmacological effect of sildenafil and its N-desmethyl metabolite equivalent to that of a 20 mg oral dose.
What should I know about storage and disposal of this medication?
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription. Keep a written list of all of the prescription and nonprescription (over-the-counter) medicines, vitamins, minerals, and dietary supplements you are taking. Bring this list with you each time you visit a doctor or if you are admitted to the hospital. You should carry the list with you in case of emergencies.
Thermal Analysis and Solid-State Characterisation
Erectile dysfunction (ED) affects about 50% of men over 40, with 26% of new cases occurring in men under 40 [1,2,3]. ED can significantly impact self-esteem, sexual well-being, and relationships, ultimately lowering overall quality of life [4]. Additionally, ED serves as an early indicator of undiagnosed or future cardiovascular issues, making its detection and management crucial for men’s overall health [5,6,7]. Phosphodiesterase type 5 inhibitors (PDE5i) are among the first-line treatment options for ED in clinical practice. Several PDE5i are available (sildenafil, tadalafil, vardenafil, avanafil), each with distinct pharmacokinetic properties and side effect profiles, along with different formulations (film-coated, oro-dispersible film) and a wide range of dosages [6], allowing for a tailored treatment strategy. Tap the bottle to release the powder.
What special precautions should I follow?
Nonetheless, most men with ED discontinue therapy within the first year due to medical and psychosocial factors (e.g., cost, relationship issues, concerns about loss of spontaneity in intercourse) [8]. Therefore, developing new PDE5i formulations that align with patients’ needs and expectations is crucial for improving treatment adherence and ultimately the couple’s sexual life. A new sildenafil oral suspension formulation (OSF) has been introduced and assessed in Spain [9].

Deaths were first observed after about 1 year and causes of death were typical of patients with PAH.
| Parameter | Value | Description | Notes |
|---|---|---|---|
| Absorption time | 30-60 minutes | Time to reach peak plasma levels | Faster onset compared to tablets |
| Peak plasma concentration | 150-200 ng/mL | Max systemic concentration | Varies per dose and individual |
| Half-life | 4-5 hours | Time to reduce concentration by half | Helps determine dosing intervals |
| Bioavailability | 40-50% | Fraction reaching systemic circulation | Slightly variable across patients |
Use of REVATIO, particularly chronic use, is not recommended in children [see Use in Specific Populations (8.4)].
- The cost of sildenafil oral solution varies depending on brand and pharmacy.
- Generic versions are typically less expensive.

REVATIO has vasodilatory properties, resulting in mild and transient decreases in blood pressure. Before prescribing REVATIO, carefully consider whether patients with certain underlying conditions could be adversely affected by such vasodilatory effects (e.g., patients on antihypertensive therapy or with resting hypotension [BP less than 90/50], fluid depletion, severe left ventricular outflow obstruction, or autonomic dysfunction). Monitor blood pressure when co-administering blood pressure lowering drugs with REVATIO.
