Papaverine

Drug Details

Papaverine is a vasodilator medication that relaxes smooth muscles in blood vessels, leading to their dilation and improved blood flow. It is used to treat various conditions involving smooth muscle spasms, such as certain types of chest pain, circulation problems, and disorders of the stomach or gallbladder. Papaverine is available in different forms, including tablets, extended-release capsules, and injections. When taken orally, the tablet is usually administered three to five times a day, while the extended-release capsule is typically taken every 8 to 12 hours. It's important to follow the prescribed dosage and not to crush, chew, or divide the extended-release capsules. Papaverine should not be used to treat erectile dysfunction, as improper use can lead to serious complications, including painful or prolonged erections that may require medical intervention. Common side effects may include dizziness, bruising or bleeding at the injection site, and mild burning along the penis when injected. Patients should consult their healthcare provider for personalized advice and report any adverse effects promptly.
