Caverject (20mcg) 1 Injection

Alprostadil, a synthetic prostaglandin E1 analog, exerts its effects by binding to prostaglandin receptors, primarily the EP1, EP2, EP3, and EP4 receptor subtypes. When administered, it stimulates adenylate cyclase, leading to increased intracellular cyclic adenosine monophosphate (cAMP) levels, which promotes smooth muscle relaxation. This mechanism is particularly relevant in vascular smooth muscle, where it induces vasodilation, resulting in the dilation of blood vessels and improved blood flow. Additionally, alprostadil inhibits platelet aggregation and promotes fibrinolysis, contributing to its therapeutic effects in certain cardiovascular and peripheral vascular disorders.

Following are the precautions and warnings for Alprostadil 20mcg injection:

• Not recommended for individuals with a known allergy to Alprostadil or other prostaglandins.
• Requires careful administration by a healthcare professional to avoid potential complications.
• Caution is advised in patients with cardiovascular diseases, as it may affect blood pressure and heart rate.
• Should not be used in patients with a history of severe bleeding disorders or those taking anticoagulant medications.
• Can cause penile pain and prolonged erections, immediate medical attention is necessary if the erection lasts longer than 4 hours.
• Not recommended for individuals with penile deformities or those who have had penile implants.
• The injection site should be monitored for signs of infection or tissue damage.

Following are the drug interactions for Alprostadil 20mcg injection:

• Alprostadil should not be used in combination with other vasodilators, including nitrates (e.g., nitroglycerin) or calcium channel blockers (e.g., verapamil), as the combination may lead to an excessive drop in blood pressure.
• Concurrent use of Alprostadil with antihypertensive drugs (e.g., ACE inhibitors, beta-blockers) may increase the risk of hypotension (low blood pressure). Blood pressure should be monitored closely.
• Combining Alprostadil with blood thinners (e.g., warfarin, aspirin) or antiplatelet agents (e.g., clopidogrel) may increase the risk of bleeding, especially in patients with a history of bleeding disorders.
• Alprostadil should be used cautiously with other drugs that can cause fluid retention or affect renal function (e.g., nonsteroidal anti-inflammatory drugs or NSAIDs), as this may enhance fluid retention and affect renal output.
• The use of Alprostadil in combination with other drugs that affect the prostate (e.g., alpha-blockers) may lead to an increased risk of adverse effects such as dizziness, hypotension, or fainting.
• When used with other medications that affect erectile function (e.g., PDE5 inhibitors like sildenafil), caution is necessary, as they may have an additive effect, potentially leading to prolonged erections (priapism) or other complications.
• Alprostadil may interact with certain drugs that affect platelet aggregation (e.g., heparin, warfarin), increasing the risk of bleeding. It is important to monitor for any signs of bleeding or bruising.
• Alprostadil should be used cautiously with other vasodilators (e.g., hydralazine), as there may be an enhanced risk of hypotension. Regular monitoring of blood pressure is recommended.

Following are the food interactions for Alprostadil 20mcg injection:

• Avoid grapefruit and grapefruit juice as they may influence blood pressure and heart rate, potentially affecting the efficacy of Alprostadil.
• Alcohol consumption should be limited as it can cause low blood pressure and may increase the risk of bleeding.
• Caffeine-rich foods and beverages like coffee, tea, and energy drinks should be consumed in moderation as they may affect blood pressure.
• High-fat meals can potentially delay the absorption of Alprostadil, so it's best to avoid fatty foods before and after the injection.
• Avoid spicy foods as they can influence blood circulation and potentially interact with the medication's effects.
• Salt intake should be monitored as high sodium levels can counteract the medication's effects on blood pressure.
• Stay hydrated by drinking enough water to maintain blood volume and support the medication's effects.
• Always consult your healthcare provider for specific dietary recommendations and adjustments during Alprostadil therapy.
