There are numerous transdermal delivery systems currently available on the market. However, the transdermal market still remains limited to a narrow range of drugs. Further advances in transdermal delivery depend on the ability to overcome the challenges faced regarding the permeation and skin irritation of the drug mols. Emergence of novel techniques for skin permeation enhancement and development of methods to lessen skin irritation would widen the transdermal market for hydrophilic compds., macromols.

- Sildenafil gel is sometimes combined with other topical vasodilators to enhance effect.
- The onset of action generally occurs within 15-30 minutes after application.
- Duration of sildenafil gel effects typically lasts 1-2 hours.
- Side effects can include local burning, redness, or itching at the application site.
- It should not be applied to broken or irritated skin to avoid complications.
- Using sildenafil gel does not protect against sexually transmitted infections.

Skin electroporation for transdermal and topical delivery. 2004, 56, 659– 674, DOI: 10.1016/j.addr.2003.10.027Google Scholar15Skin electroporation for transdermal and topical deliveryDenet, Anne-Rose; Vanbever, Rita; Preat, VeroniqueAdvanced Drug Delivery Reviews (2004), 56 (5), 659-674CODEN: ADDREP; ISSN:0169-409X. Electroporation is the transitory structural perturbation of lipid bilayer membranes due to the application of high voltage pulses. Its application to the skin has been shown to increase transdermal drug delivery by several orders of magnitude.

Moreover, electroporation, used alone or in combination with other enhancement methods, expands the range of drugs (small to macromols., lipophilic or hydrophilic, charged or neutral mols.) which can be delivered transdermally. transport through transiently permeabilized skin by electroporation results mainly from enhanced diffusion and electrophoresis. The efficacy of transport depends on the elec. The in vivo application of high sildenafil 100g voltage pulses is well tolerated but muscle contractions are usually induced. The electrode and patch design is an important issue to reduce the discomfort of the elec. 16Ogura, M.; Paliwal, S.; Mitragotri, S. Low-frequency sonophoresis: current status and future prospects.
- Sildenafil gel allows more discreet and flexible dosing schedules.
- It offers an alternative for men experiencing side effects from oral sildenafil.
- Proper hygiene before application reduces infection risk.
