If you’re thinking of taking the drug Cialis, you might have noticed that the drug’s manufacturer, Pfizer, has taken a step closer to making it more widely available.
In the first half of 2021, the company’s biggest patent expirations in the U. S. were in Europe and the UK. The UK-based company has also had a positive regulatory outlook.
Pfizer’s move is expected to be an important step in boosting the availability of generic versions of the drug.
Pfizer’s patents on Viagra and Cialis have expired since 2011. Viagra is a branded version of the drug, which contains sildenafil citrate. The drug’s patent allows the drug to be sold in generic form and to be available in its branded version.
However, the company’s patent exclusivity has expired.
In April 2021, Pfizer announced that it had taken a bold step towards a generic version of the drug, which would be more widely available.
Pfizer’s move to allow generic versions of the drug is a move that will help in the fight against the pharmaceutical industry’s overreaching.
The decision to take a bold step in this direction has been met with strong support from the pharmaceutical industry, including the American consumer protection advocacy organization Consumer Reports.
The pharmaceutical industry has been pushing for generic versions of the drug since the 1990s. Pfizer has been the first company to offer an online service that enables the drug to be manufactured, sold and distributed.
For the first time, the company has launched an online pharmacy that allows customers to order generic Viagra and Cialis.
As the patent expirations continue to push for generic versions of the drug, the company’s focus on expanding its presence in the US is expected to be supported by a large number of pharmaceutical companies.
The company is also expected to introduce an online pharmacy that will allow customers to order generic Viagra and Cialis online and receive payment via debit or credit card.
Pfizer also announced that it has also been the first company to offer generic Viagra and Cialis to customers in the UK.
1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals.
