Viagra, Cialis, Levitra and Lasik

Erectile Dysfunction medications and interaction with Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, CK, RLE, and P-IOL

Viagra, Cialis, and Levitra may not directly affect Lasik, but their side effects can be similar.

 

The use of the class of drugs called phosphodiesterase-5 (PDE-5) inhibitors including sildenafil (Viagra), vardenafil (Levitra) and tadalafil (Cialis) for erectile dysfunction should not be a direct contraindication for most cornea-based refractive surgery techniques, including conventional or wavefront Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, and CK, nor should it be a direct problem for lens-based P-IOL, and RLE, however these medications can be a serious indirect problem.

Some of the side effects of erectile dysfunction medications are similar to side effects of refractive surgery.  If something goes wrong after surgery and the patient is using an erectile dysfunction medication, it may be difficult to determine if the cause is the surgery or the medication.

Some of the common and less common side effects of this class of medicine are headache, nasal congestion, abnormal vision including blurred vision, seeing shades of colors differently than before, or sensitivity to light, dizziness, bleeding of the eye, decreased or double vision, redness, burning, or swelling of the eye, and anxiety.  Needless to say, someone who has just had surgery doesn't want any of these potential problems.  Additionally, these types of medications may interfere or be a contraindication for other medications that could become necessary after refractive surgery.

It appears that it would be best to refrain from use of erectile dysfunction medications for at least three days before surgery and until the eye is healed and stabilized.  Of course, this is an issue that needs to be discussed with your physician and refractive surgeon.

If you are ready to choose a doctor to be evaluated for conventional or custom wavefront Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, NearVision CK, RLE, or any refractive surgery procedure, we highly recommend you consider a doctor who has been evaluated and certified by the USAEyes nonprofit organization.

Mechanism of relaxation and interaction with nitric oxide of the soluble guanylate cyclase stimulator BAY 41-2272 in mouse gastric fundus and colon.

Mechanism of relaxation and interaction with nitric oxide of the soluble guanylate cyclase stimulator BAY 41-2272 in mouse gastric fundus and colon.

Eur J Pharmacol. 2012 May 2;

Authors: Cosyns SM, Lefebvre RA

Abstract
BAY 41-2272 is a heme-dependent nitric oxide-independent soluble guanylate cyclase (sGC) stimulator, but its relaxant effect in vascular, respiratory and urogenital tissue is only partially dependent on sGC activation. As its mechanism of action has not been studied in the gastrointestinal tract, it was investigated in mouse gastric fundus and colon. Circular smooth muscle strips were mounted in organ baths under nonadrenergic noncholinergic (NANC) conditions for isometric force recording and cGMP levels were determined using an enzyme immunoassay kit. BAY 41-2272 induced concentration-dependent relaxation in both tissues and increased cGMP levels. The sGC inhibitor ODQ totally inhibited this BAY 41-2272-induced increase of cGMP, but only partially reduced the corresponding relaxation. PDE-5 inhibitor sildenafil had no effect on BAY 41-2272-induced responses. The NO synthase inhibitor L-NAME caused a significant decrease in BAY 41-2272-induced responses in colonic strips. Electrical field stimulation in the presence of BAY 41-2272 induced increased NANC relaxation in fundus, while in colon, rebound contraction at the end of the stimulation train was no longer visible. This suggests synergy with endogenously released NO. Responses to BAY 41-2272 were not significantly influenced by apamin, charybdotoxin or ouabain, excluding interaction with small, intermediate and large conductance Ca(2+)-activated K(+) channels and with Na(+)-K(+)-ATPase. Under depletion of intracellular calcium, CaCl(2)-induced contractions were significantly reduced by BAY 41-2272 in an ODQ-insensitive way. The present study demonstrates that BAY 41-2272 exerts its relaxing effect in mouse gastric fundus and colon partially through a cGMP-dependent mechanism and at least one additional cGMP-independent mechanism involving Ca(2+)-entry blockade.
