Moreover, the comparison of pharmacokinetic parameters between the sildenafil ODF administered with and without water and the conventional film-coated tablet were similar. It also demonstrated reliable performance that yielded a consistent product, meeting all specifications at release and after three weeks of storage under stressed conditions (60°C). Sildenafil ODF warrants improved ease of intake, taste, portability, storage, and compliance among ED patients, making it the potential most preferred formulation and drug of choice.

Expert Commentary

Erectile dysfunction (ED) prevails as an unprecedented diagnosis and undertreated condition. It is considered as the perfect gender-dependent (early) biomarker of non-communicable diseases (NCDs) including central and peripheral cardiovascular disease, with a heightened risk of related mortality. The effective management of ED reduces these risk factors and sildenafil pills halts the progression of disease. Sildenafil citrate, a selective phosphodiesterase-5 inhibitor, is recommended as a first-line treatment for ED owing to its proven efficacy and established safety profile. Recently, a novel sildenafil orodispersible film (ODF) dosage form, which offers rapid disintegration in seconds when placed on the tongue, was developed. Although there are several names employed to refer oral film dosage forms like thin strips, oral thin films, quick dissolve films, oral films, melt-away films, orally dissolving films, and wafers, they are officially named as ODF by the European Medicines Agency (EMA) or as soluble films by the United States Food and Drug Administration (U.S.

Currently, they are available in various forms, including adhesive tablets, gels, ointments, patches, and mouth-dissolving films for buccal delivery [Citation4]. These buccal drug delivery systems over time became a suitable alternative drug form for tablets or capsules. In addition, the oral cavity serves as an ideal route of administration due to its highly vascularized thin membranous structure. Apparently, the lower enzymatic activity in the oral mucosa provides greater permeability and rapid absorption of several drugs, especially drugs with low aqueous solubility. It also bypasses first-pass metabolism, potentiates higher systemic bioavailability of active pharmaceutical ingredients (APIs), and ensures a rapid onset of action [Citation5].

Discreet Package

Oral disintegrating tablets (ODTs) are a kind of oral solid dosage form intended to disintegrate swiftly within seconds of placement on the tongue without necessitating water or chewing [Citation5,Citation6]. Orodispersible films buy sildenafil uk (ODFs) are a drug delivery system that encompasses thin, flexible sheets manufactured with or without plasticizers that usually disperse or disintegrate promptly, usually within seconds, once placed in the mouth. They are designed to be positioned in the buccal cavity either above the tongue or between the gums and cheeks and get directly absorbed into the blood stream. They can be used to deliver different categories of medications, including prescription and non-prescription, or over-the-counter drugs [Citation5]. The use of ODFs is well-known to resolve issues related to conventional oral dosage forms that include but are not limited to (i) accelerating the time of drug release, (ii) prolonged duration of drug action, (iii) reduced number of dose administrations, and (iv) maximized efficacy of APIs [Citation7]. Other relevant articles were identified by manually reviewing the reference list of selected articles. Orodispersible dosage forms have an ever growing presence in the pharmaceutical market considering that their administration can enhance the bioavailability of most of the drugs and their prescription can ameliorate patient adherence and/or compliance [Citation10].

Orodispersible film (ODF) is one of the novel formulations that disintegrate rapidly in the mouth without the requisite for water compared to other conventional oral solid dosage formulations. This delivery system serves as a convenient mode of administration, especially in patients who have dysphagia and fluid restriction, being beneficial to pediatric, geriatric, and bedridden patients. A novel sildenafil ODF containing sildenafil citrate is formulated to be used in patients with erectile dysfunction (ED). This novel technique has transformed the usual drug delivery methodology for oral drugs.

Society and culture

We conducted this narrative review to understand the advancements, advantages, and disadvantages of these innovative formulations. ODFs are innovative and sophisticated drug delivery systems that offer several advantages over conventional formulations. The unique benefits of sildenafil ODF includes administration of the film before engaging in sexual activity without the need for water and rapid disintegration of ODF within seconds unlike traditional pills. The sildenafil ODF also demonstrated reliable performance at elevated temperature (stress test), ensuring the stability of the pharmaceutical product during transport, storage, and handling. ODFs have transformed the conventional ways of oral drug delivery.

6.1 Clinical Trials Experience

The sildenafil ODF is widely prescribed and preferred among ED patients as it respects patients’ privacy with its ease of use, portability, efficacy, and safety. Oral medications remain the most preferred and accustomed method of drug delivery owing to several advantages they offer, including convenience of self-administration and high patient compliance among others [Citation1]. However, some patient groups, including the geriatric and pediatric groups, individuals with Parkinson’s disease or Alzheimer’s disease and psychiatric conditions, and patients with dysphagia, often confront challenges in swallowing and chewing solid oral dosage forms [Citation1–3]. Thus, to overcome these issues, extensive efforts were taken to create novel oral drug delivery systems with the aim of providing drugs that could dissolve or disperse in the oral cavity and form solution or suspension without the requirement of water. These fast-dissolving oral drug delivery systems were first devised in the late 1970s and became prominent as oral mucosal dosage formulations. These modified dosage forms, oral films, have replaced oral tablets as they have achieved altered drug release characteristics and faster disintegration.

• Sildenafil oral strips provide a non-invasive way to treat ED.
• They avoid swallowing pills, which some patients find difficult.
• Strips are often manufactured with pleasant flavors to enhance appeal.
• The medication’s effect can be influenced by food intake.
• Alcohol consumption may reduce effectiveness or increase side effects.
• Sildenafil strips should be used as prescribed and not mixed with other ED drugs.
• These strips are designed for quick absorption in the oral mucosa.
• Overuse or misuse can lead to adverse health effects.
• Proper dosing helps minimize risks of prolonged erections or priapism.
• Sildenafil strips do not cure ED but help manage symptoms.
• They may be used in combination with psychological or lifestyle interventions.
• Always check expiration dates before using sildenafil strips.

Also, conventional tablets may get easily broken down, necessitating considerable packaging during handling, storage, and transit, while oral films are flexible, handy, and can be kept for long-term use [Citation14]. An ideal and authentic rapid dissolving delivery system is expected to possess the following properties: (i) optimal stability and transportability, (ii) uncomplicated handling and administration, (iii) no distinctive packaging material or processing requirements, (iv) no requirement of water for application, and (v) acceptable palatability.

Introduction to S-FILM Orally Disintegrating Strip

Besides, this innovative drug delivery system or film technology offers an array of benefits during the pharmacokinetics and pharmacodynamic aspects of the drugs, including (i) improved absorption and metabolism, (ii) site-specific action, (iii) lowering of side effects, and (iv) most significantly enhancing the drug’s bioavailability. ODFs also confer expeditious dissolution, pertinent drug loading capacities, and improved stability and durability of drug formulations. Moreover, they are safe, secure, nontoxic, bioresorbable, and biodegradable. Furthermore, as ODTs evolved, the ODFs achieved patient compliance by circumventing discomfort due to their user-friendly advantages. Thus, the ODFs provide immediate release and disintegration; rapid onset of action; and disease- and target-specific drug action that results in instant and effective reduction of symptoms, relieves discomfort, and restores normal physiological function.
