Why was Levitra discontinued?

Could you please elaborate on the reasons behind the discontinuation of Levitra? Was it due to safety concerns, lack of efficacy, or perhaps a strategic decision by the manufacturing company? Consumers who have relied on this medication for their health needs would surely be curious to understand the rationale behind this decision. Additionally, are there any alternative treatments or medications that patients can consider as a replacement for Levitra? It would be helpful to have a clear picture of the situation and its implications for patients' health and wellbeing.
