The amount of degradation products demonstrated an increasing trend over time in all conditions, but all met the required specification. The purity testing for the degradation product (0.2% or less) showed significant results (p value < 0.05) at initial and 60°C in all the three samples. The process was evaluated across a range of manufacturing conditions, and all intermediates and sildenafil ODF showed reliable performance that yielded a consistent product meeting all specifications at release and after three weeks of storage under stressed conditions. These results, shown in , indicate the robust performance of the sildenafil ODF across a range of manufacturing conditions. In addition, the water content stayed in a tight range regardless of the film casting parameters, and this remains true of the packaged product even after 3 weeks at 60°C.

Who should not take sildenafil?

ED is defined as the persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance [Citation76,Citation79–81]. ED still prevails as an unprecedented diagnosis and undertreated condition that contributes to increased physical and psychosocial burden. It negatively impacts the wellbeing, relationships, and health-related quality of life (HR-QoL) of patients and their partners [Citation82,Citation83], and thus, any treatment interventions that substantially revive sexual function have the prospect to reinforce patient health and overall HR-QoL. ED may present with clinically relevant forms but also subclinical conditions deserving medical attention. Worldwide, various forms of ED are diagnosed in up to 150 million men and it has been projected to surge to 322 million cases by 2025.

5.8 Effects on Bleeding

ED has affected 52% of men in the age group of 40 and 70 years and 70% of men above 70 years [Citation84–87]. The primary risk factors include diabetes mellitus, hypertension, and hyperlipidemia and modifiable risk factors like obesity, physical inactivity, alcoholism, and cigarette smoking [Citation88–90]. In addition, there is increasing evidence that ED can be considered as the perfect gender-dependent (early) biomarker of non-communicable diseases (NCDs) including peripheral vascular disease and cardiovascular disease, with a heightened risk of cardiovascular mortality as largely demonstrated by epidemiological studies [Citation91]. Indeed, ED can be considered a symptom for underlying NCD that may be explained as the classical canary in the coalmine [Citation92]. The management of ED includes the identification and control of risk factors and appropriate pharmacological and non-pharmacological therapy. ED is defined as the persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance [Citation76,Citation79–81].

Indeed, ED can be considered a symptom for underlying NCD that may be explained as the classical canary in the coalmine [Citation92]. The management of ED includes the identification and control of risk factors and appropriate pharmacological and non-pharmacological therapy. The treatment strategies undoubtedly can reduce the initial symptoms and halt the progression of the disease. Some of the treatment approaches encompass psychosexological strategies, intraurethral or intracavernosal alprostadil self-injections, vacuum-assisted erection devices, low-intensity extracorporeal shock wave treatment, and penile implants. Nevertheless, after the efforts to modify unhealthy lifestyle and control risk factors and comorbidities, pharmacological management with oral buy sildenafil uk PDE5-Is stays as the first-line treatment choice for ED because of its proven efficacy and better safety profile [Citation8]. The PDE5-Is inhibit the PDE5 enzyme concentrated in the smooth muscle cells in the blood vessels [Citation93]. Due to this inhibition, PDE5-Is prevent the enzyme-initiated degradation of cyclic guanosine monophosphate (cGMP), which causes elevation of cGMP in the vascular smooth muscle. Elevated cGMP levels lead to dilatation of the blood vessels due to phosphorylation of various downstream effector molecules, ensuring relaxation of smooth muscles [Citation94]. Inhibiting PDE5 produces a dilatation of the penile arteries that leads to a more prolonged and stable erection. Futhermore, PDE5-Is improve endothelial function and decrease apoptosis of smooth muscle cells in the corpus cavernosum [Citation93,Citation95]. Till date, the PDE5 inhibitors approved for the treatment of ED by the US Food and Drug Administration and European Union (EU) include sildenafil, tadalafil, vardenafil, and avanafil [Citation82,Citation96–98].

Sildenafil citrate, the first-in-class PDE5-I, is the most potent and selective inhibitor of cGMP-specific PDE5.

What are the serious side effects of sildenafil?

Since its launch for the treatment of ED in 1998 in the market, there has been a well-established evidence base for its effectiveness and safety of sildenafil. It is the most efficacious drug, from a vascular perspective, among other PDE5-Is [Citation99]. This established efficacy of sildenafil in ED is irrespective of confounding factors including age, baseline severity, or etiology of ED [Citation100]. Although, sildenafil ODT is marketed at various strengths of 25, 50, and 100 mg, 50 mg is the recommended dose for most of the patients with directions to be approximately taken one hour before sexual activity. The dose can be titrated to a maximum of 100 mg or reduced to 25 mg considering individual patient’s needs, tolerability, and efficacy.

Headache and flushing are the most commonly reported side effects [Citation101]. Sildenafil is supplied in both solid film-coated tablet (FCT) and orodispersible tablet formulations. The sildenafil ODT and ODFs are made available through implementation of innovative manufacturing technologies [Citation8,Citation102]. It is also offered as chewable tablets and an orally soluble orodispersible film formulation [Citation82]. conducted a randomized clinical trial that reported bioequivalence of sildenafil ODT with or without water compared to marketed film-coated tablets. This study also identified the effect of food on the release pattern of drug and demonstrated the benefits of the administration of sildenafil ODT on empty stomach [Citation103].

What other information should I know?

examined and reported the bioequivalence of sildenafil citrate ODF and FCT with and without water in 2 randomized crossover studies [Citation75]. Owing to its unique pharmacological characteristics, quick disintegration within seconds, the novel sildenafil ODF is widely prescribed and preferred among ED patients. A study conducted in Japan surveyed 25 patients with ED regarding the ease of consumption and portability with the use of sildenafil ODF formulation. The survey items comprised (i) portability, (ii) storage techniques, (iii) ease of consumption, (iv) comfortableness, (v) extent of self-consciousness with their partner, (vi) thoughts on administering the film formulation, (vii) comparison with the tablets, and (viii) efficacy and adverse reaction. Of all the participants, 61.5% of the patients who switched from tablets to film quoted that storage and portability were improved and were comfortable during consumption. The study reported that most of their patients felt more at ease (69.2% who swapped from tablets to film and 75.0% belonged to the prescribed film-only category) and more comfortable with the film (61.5% who switched from tablets to film and 66.7% belonged to the prescribed film-only category). Mild hot flashes and headache were the only two adverse reactions with no severe adverse reaction reported by the study participants.

Common side effects include headache, flushing, and nasal congestion.
Serious side effects are rare but may include vision changes or priapism.
Always consult with a healthcare provider before use.

The survey demonstrated improved ease of intake and portability with the orodispersible film compared to tablets [Citation104].

Sildenafil film tablets are available by prescription only.
They may interact with nitrates, causing dangerous blood pressure drops.
Alcohol can impair the effectiveness of these tablets.

However, the efficacy sildenafil citrate tablets for female of PDE5-Is has been thoroughly established, and the documented evidence reveals that a prominent proportion of patients discontinued this pharmacological therapy prematurely. There is a gradual dissatisfaction noticed with the prescribed therapy among patients despite their successful intercourse.

Side Effects

There is a gradual dissatisfaction noticed with the prescribed therapy among patients despite their successful intercourse. Studies depict that approximately 50% of men abandon their treatment with PDE5-Is in conventional formulations within a year [Citation105]. There is an immense need to understand individual patient’s needs and expectations regarding treatment for ED and also to comprehend their personal experiences and preferences. This will be instrumental in deciphering successful patient outcomes and satisfaction regarding the pharmacological therapy [Citation8]. ODFs were developed to overcome the above drawbacks of conventional oral solid dosing forms and to significantly improve patients’ compliance and acceptability to the pharmacological therapy.

Does sildenafil interact with foods or drinks?

ODFs are innovative and sophisticated drug delivery systems that disintegrate instantly in the mouth without the need for water. They unveil a prudent and easy mode of administration, with no risk of choking or inconvenience during swallowing. These attributes of ODFs improve compliance specifically in patients with dysphagia, and children and elderly population with comorbidities (e.g., renal impairment or congestive heart failure) when compared with conventional tablets or capsules. This noninvasive drug delivery system offers an altered clinical profile as it surpasses the enterohepatic circulation [Citation8]. Since the drug gets absorbed majorly from buccal mucosal tissues, it also reduces the risk of formation of toxic metabolites due to lowered hepatic metabolism [Citation106].

Sildenafil Oral Film Dosage and Administration

ODFs with their convenience, together with superior dosing accuracy and swift onset of action, have transpired in strong patient preference among various patient groups. Since each film or strip consists of precise quantities of the APIs and is devoid of physiological variability in the gastrointestinal tract, there is minimal intersubject variability in clinical response unveiled by ODFs [Citation107]. Given all these advantages, growing body of research illustrates that majority of patients and prescribers prefer orodispersible dosage forms over conventional oral solid dosage forms [Citation108,Citation109]. There are fewer limitations with ODFs such as complex manufacturing processes and requirement of specialized equipment that may significantly increase the production costs. Also, these innovative formulations may face different challenges compared to traditional dosage forms during application and regulatory approval processes, necessitating additional studies to evaluate safety, efficacy, and stability. Studies depict that approximately 50% of men abandon their treatment with PDE5-Is in conventional formulations within a year [Citation105]. There is an immense need to understand individual patient’s needs and expectations regarding treatment for ED and also to comprehend their personal experiences and preferences.

Sildenafil film tablets typically start working within 30-60 minutes.
The recommended dose varies, often 50mg before sexual activity.
Do not take more than one tablet per 24 hours.

This will be instrumental in deciphering successful patient outcomes and satisfaction regarding the pharmacological therapy [Citation8]. ODFs were developed to overcome the above drawbacks of conventional oral solid dosing forms and to significantly improve patients’ compliance and acceptability to the pharmacological therapy.

5.2 Prolonged Erection and Priapism

Headache and flushing are the most commonly reported side effects [Citation101]. Sildenafil is supplied in both solid film-coated tablet (FCT) and orodispersible tablet formulations.
