6. Adverse Reactions/Side Effects

Viagra could soon be getting some very stiff competition. Researchers in Australia claim to have developed a nasal spray to combat erectile dysfunction — and it could be rolled out to American consumers within two years. The spray-to-play product reportedly works in as little as five minutes, meaning it could be a bedroom game changer for the 30 million Americans who struggle to gain and maintain an erection. “Our nasal delivery bypasses the digestive system, so it really goes straight into the bloodstream and has an effect in five to 15 minutes,” Lee Rodne, executive chairman of biotech company LTR Pharma, told the Australian on Monday. “We expect it to be a lot more effective than oral tablets so that it works consistently and in a quicker and faster amount of time, so men don’t have to plan ahead and they don’t have variable results,” he enthusiastically added.

Viagra is one of the most popularly prescribed medications for erectile dysfunction; however, it usually takes between 30 to 60 minutes to kick in. The new spray, dubbed SPONTAN, “repurposes” the PDE5 inhibitor Vardenafil, which is taken orally one to two hours before sexual activity. PDE5 inhibitors are a group of medications commonly used to treat erectile dysfunction and include sildenafil (sold under the brand name Viagra) and tadalafil (sold as Cialis). A clinical trial will soon begin in Australia to compare the results of SPONTAN against the results of a different PDE5 inhibitor that will be taken orally. LTR Pharma has “very high confidence” that the results will be a success and wants the product to hit the US market in 2025. 10 Mar 2026 Aspargo Laboratories filed application with MHRA to reclassify Sildenafil as Pharmacy (P) medicine status in the United Kingdom 24 Dec 2025 Aspargo Labs plans a phase I pharmacokinetics trial (in voulnteers) in March 2026 (NCT07302698) 24 Dec 2025 Aspargo Laboratories plans a phase II crossover trial for Erectile dysfunction (PO), in April 2026 (NCT07290400) Aspargo plans to file a new drug application with the FDA to support regulatory approval of ASP-001 for erectile dysfunction in the United States. Findings from a recent phase 1 trial show that ASP-001, an investigational sildenafil oral spray for patients with erectile dysfunction, achieved therapeutic levels at a significantly faster rate compared with traditional sildenafil citrate tablets (Viagra), announced Aspargo Labs, the developer of the formulation, in a news release.1 “The rapid and enhanced absorption profile demonstrated by ASP-001 in this phase 1 study highlight its potential to address key unmet needs in the treatment of erectile dysfunction,” said Steven Kaplan, MD, Chief Medical Officer at Aspargo Labs, director of the Men’s Wellness Program at the Mount Sinai Health System, and a professor at the Icahn School of Medicine at Mount Sinai.1 “Many patients struggle with the inconvenience and lack of spontaneity associated with planning ahead to take a tablet and the requirement to fast or time their dosing.

Warnings & Precautions

Less frequently, some men may encounter visual disturbances or stomach upset. It is important to adhere to recommended dosages and avoid exceeding the prescribed amount to minimize adverse effects. Users with certain health conditions, such sildenafil products over the counter as cardiovascular issues or those taking medications containing nitrates, should consult their healthcare provider before use. Alcohol consumption and high-fat meals can also affect the medication’s effectiveness, so caution is advised when combining these in lifestyle choices. For optimal results, it is recommended to spray the medication directly onto the inside of the mouth, preferably under the tongue or against the cheek.

This method allows for rapid absorption into the bloodstream. The timing of administration varies depending on individual response but generally should be taken about 15 to 30 minutes before intended sexual activity. The typical dose should not be exceeded to reduce the risk of side effects. It is vital to follow the instructions provided with the medication and to consult a healthcare professional if there is any uncertainty or existing health concerns.

If approved, ASP-001 would be a welcome addition to the treatment landscape, offering patients and their partners a novel and practical option to enhance their sexual health and overall quality of life.” Overall, data from the phase 1 study showed that ASP-001 achieved initial absorption within 5 minutes of administration. At this time point, the average amount of medication in the bloodstream was 0.615 ng/mL with ASP-001, vs 0 ng/mL with sildenafil tablets. The average level of medication in the bloodstream via mean plasma concentrations remained higher for those who received ASP-001 vs those who received sildenafil tablets for the first 30 minutes following administration. In total, the open-label, single center, 2-way crossover study included 53 healthy, fasted male volunteers. Participants were randomly assigned to receive either 4 mL of ASP-001 or to 100 mg sildenafil tablets.

16. How is Sildenafil Oral Suspension supplied

The Post has contacted the company for further comment. Meanwhile, SPONTAN isn’t the only product that could soon be challenging Viagra. Late last year, a saucy study found injections of Botox directly into the penis provide “a clear benefit” for men suffering from erectile dysfunction. Sildenafil Oral Spray is a convenient and rapidly absorbed medication designed to treat erectile dysfunction in men. Unlike traditional oral tablets, this spray form allows for easier and quicker administration.

It is formulated to provide the same benefits as the well-known Sildenafil Citrate but offers enhanced ease of use, especially for those who have difficulty swallowing pills or prefer a discreet method of intake. The medication works by increasing blood flow to the penile area, helping men achieve and maintain an erection suitable for sexual activity. The active ingredient in this medication, Sildenafil Citrate, is a phosphodiesterase type 5 (PDE5) inhibitor. When a man is aroused, nitric oxide is released in the erectile tissue of the penis. Nitric oxide activates an enzyme that increases levels of cyclic guanosine monophosphate (cGMP), leading to smooth muscle relaxation and increased blood flow. “Our innovative oral spray technology has been carefully developed to provide a novel approach for administering medication, simplifying the process of drug consumption,” said Michael Demurjian, CEO of Aspargo Labs, in the news release.1 “The study data provides evidence for the safety and pharmacokinetic profile of our oral spray technology. Our research has demonstrated that ASP-001 exhibits rapid absorption, surpassing the absorption rate of Viagra tablets in the initial minutes after administration. We look forward to collaborating with the FDA to file an NDA for ASP-001 for the treatment of ED under the 505(b)2 regulatory pathway and are enthusiastic about the opportunity to make this drug available to patients in the US.” Aspargo Labs announces data on first oral spray for erectile dysfunction, ASP-001, showing two times faster absorption compared to Viagra tablets.

Sildenafil works by inhibiting the PDE5 enzyme, which breaks down cGMP. This inhibition prolongs the effects of nitric oxide, facilitating a stronger and longer-lasting erection. Due to its spray form, the medication is absorbed through the mucous membranes in the mouth, allowing for faster onset compared to tablets taken orally." One of the key benefits of this medication is its rapid absorption. Typically, effects are felt within 15 to 30 minutes after application, making it a convenient choice for spontaneous intimacy. The spray form also reduces the chance of gastrointestinal discomfort that some may experience with tablets.

2. Topical ED gels (like MED3000/Eroxon)

Additionally, it offers precise dosage control, as each spray delivers a pre-measured dose of sildenafil. Its discreet nature makes it suitable for use in various settings without attracting attention. Patients also appreciate the reduced need to plan ahead, thanks to the quicker onset of action. While Sildenafil Oral Spray is generally well tolerated, some users may experience side effects. Common issues include headaches, flushing, nasal congestion, or dizziness. Aspargo announces completion of dosing of all subjects in sildenafil oral suspension bioavailability study and initiation of dosing in companion food-effect study. Hezkue is an oral spray for erectile dysfunction (ED) that can be used as an alternative to a pill like Viagra.
